When Ichiro joined his high-school baseball team, his father told the coach, “No matter how good Ichiro is, don’t ever praise him. We have to make him spiritually strong.” When he was ready to enter high school, Ichiro was selected by a school with a prestigious baseball program, Nagoya’s Aikodai Meiden (ja:愛工大名電) High School. Ichiro was primarily used as a pitcher instead of as an outfielder, owing to his exceptionally strong arm. His cumulative high-school batting average was .505, with 19 home runs. He built strength and stamina by hurling car tires and hitting Wiffle balls with a heavy shovel, among other regimens. These exercises helped develop his wrists and hips, adding power and endurance to his thin frame. Despite his outstanding numbers in high school, Ichiro was not drafted until the fourth and final round of the NPB draft in November 1991, because many teams were discouraged by his small size of 5 ft 9 ⁄2 in (177 cm) and 124 pounds (56 kg). Years later, Ichiro told an interviewer, “I’m not a big guy, and hopefully kids could look at me and see that I’m not muscular and not physically imposing, that I’m just a regular guy. So if somebody with a regular body can get into the record books, kids can look at that. That would make me happy.”

Ichiro made his NPB Pacific League debut in 1992 for the Orix BlueWave at the age of 18, but he spent most of his first two seasons in the farm system (accumulating 156 minor league hits and a .368 batting average) because his then-manager, Shōzō Doi, refused to accept Ichiro’s unorthodox swing. The swing was nicknamed ‘pendulum’ (振り子打法, Furiko Dahō) because of the pendulum-like motion of his leg, which shifts his weight forward as he swings the bat, and goes against conventional hitting theory. In his second career game, he recorded his first ichi-gun (Japan’s Nippon Professional Baseball League) hit in the Pacific League against Fukuoka Daiei Hawks pitcher Keiji Kimura. Even though he hit in 1993 a home run against Hideo Nomo, who later won an MLB National League Rookie of the Year Award while a Los Angeles Dodger, Ichiro was nevertheless sent back to the farm system on that very day. In 1994, he benefited from the arrival of a new manager, Akira Ōgi, who played him every day in the second spot of the lineup. He was eventually moved to the leadoff spot, where his immediate productivity dissolved any misgivings about his unconventional swing. He set a Japanese single-season record with 210 hits, the first player ever to top 200 hits in a single season. Five other players have since done so: Matt Murton, Norichika Aoki (twice), Alex Ramírez, Tsuyoshi Nishioka, and Shogo Akiyama’s 216 hits in 2015, but those players benefited from 140+ game seasons while Ichiro’s 210 hits had come in a 130-game season.

Due to an agreement between Japanese baseball and the MLB, Ichiro was not allowed to play in the United States before 2001. His move to the United States was viewed with some interest because he was among the first Japanese position players to play for an MLB team. In the same way that many Japanese teams had considered the 18-year-old Ichiro too small to draft in 1992, many Americans believed he would prove too frail to succeed against Major League pitching or endure the longer 162-game season. Ichiro made an auspicious debut with Seattle, and in the Mariners’ eighth game revealed his tremendous throwing arm by gunning down Oakland’s Terrence Long, who had tried to advance from first to third on a teammate’s single to right field. That play would be dubbed “The Throw” by Japanese media covering Ichiro’s progress.

Ichiro’s .385 batting average in 1994 was a Pacific League record and won the young outfielder the first of a record seven consecutive batting titles. Ichiro also hit 13 home runs and had 29 stolen bases, helping him to earn his first of three straight Pacific League MVP (Most Valuable Player) awards.

On 6 September against the Oakland A’s, Ichiro collected his 2,000th MLB hit on the second pitch of the game, a double along the first base foul line. He is the second-fastest player to reach the milestone, behind Al Simmons. On 13 September against the Texas Rangers, Ichiro collected his 200th hit of the season for the ninth consecutive year, setting an all-time major league record. Ichiro recorded 210 hits with Orix in 1994, thereby giving him a total of ten 200 hit seasons in his professional career.

In 1995, Ichiro led the Blue Wave to its first Pacific League pennant in 12 years. In addition to his second batting title, he led the league with 80 RBI and 49 stolen bases, while his career-high 25 home runs were third in the league. By this time, the Japanese press had begun calling him the “Hit Manufacturing Machine” (安打製造機, Anda Seizōki). The following year, with Ichiro winning his third-straight MVP award, the team defeated the Central League champion, Yomiuri Giants, in the Japan Series. Following the 1996 season, playing in an exhibition series against a visiting team of Major League All-Stars kindled Ichiro’s desire to travel to the United States to play in the Major Leagues.

Ichiro has long been interested in pitching professionally, and he actually took the mound to pitch to one batter in the 1996 NPB All Star game, reaching close to 91 MPH (145 km) in warm up pitches. In 2009, it was reported that during an early February workout at the World Baseball Classic his fastball was clocked at 92 MPH. On the final day of the 2015 season on 4 October, Ichiro pitched in his first MLB game, throwing one complete inning at the end of a 7–2 Marlins loss against the Philadelphia Phillies, allowing one run on two hits. He was still able to touch 88 mph with his fastball to go along with a mid 80s slider.

In May and June, Ichiro hit in 25 consecutive games, breaking the previous Seattle Mariners record set by Joey Cora in 1997. Ichiro broke Tim Raines’ American League record by stealing 41 consecutive bases without being caught. Ichiro extended the record to 45; the major league record of 50 belongs to Vince Coleman.

In November 1998, Ichiro participated in a seven-game exhibition series between Japanese and American all-stars. Ichiro batted .380 and collected seven stolen bases in the series, winning praise from several of his MLB counterparts, including Sammy Sosa and Jamie Moyer (who would become his teammate with the Mariners).

Ichiro married Yumiko Fukushima (福島弓子, Fukushima Yumiko), a former TBS TV announcer, on 3 December 1999, at a small church in Santa Monica, California. They have no children. They have a pet dog (Shiba Inu) named Ikkyu, a combination of “Ichi” (一) of “Ichiro” and “Yumi” (弓) of “Yumiko”, which can be vocalized kyu as well. The couple resided in Issaquah, Washington, during the season while he played in Seattle and in Greenwich, Connecticut, while he played for the Yankees. They resided in Miami Beach during seasons with the Marlins.

In 2000, Ichiro was still a year away from being eligible for free agency, but the Blue Wave was no longer among Japan’s best teams. Because the team would probably not be able to afford to keep him, and would lose him without compensation in another year, Orix allowed him to negotiate with Major League clubs. Ichiro used the posting system, and the Seattle Mariners won the right to negotiate with him with a bid of approximately $13 million. In November, Ichiro signed a three-year, $14 million contract with the Seattle Mariners. In his nine NPB seasons in Japan, Ichiro had 1,278 hits, a .353 career batting average, and won seven Golden Glove Awards. Ichiro’s time in the Japanese baseball leagues matured him as a player and a person, and he often credits it for his success.

Since November 2000, Nobuyuki has run the Ichiro exhibition room named “I-fain” in Toyoyama, Ichiro’s hometown. It exhibits a wide variety of Ichiro memorabilia, including personal items from his childhood and up-to-date baseball gear.

2001 had been an exceptionally successful regular season for the Seattle Mariners as a team, as they matched the 1906 Chicago Cubs’ Major League record of 116 wins. In his only postseason appearance with the Mariners, Ichiro continued his hot hitting into the playoffs, batting .600 in the ALDS against the Cleveland Indians. However, on Ichiro’s 28th birthday, Seattle’s stellar season ended against the New York Yankees in the ALCS, as Ichiro was held to a .222 average during the series. Yankees manager Joe Torre had emphasized to his pitchers, “Do not let Ichiro beat you. He is the key to Seattle’s offense.” Informed of this assessment, Ichiro said, “If that is true, it would give me great joy. I don’t believe he is right.”

From 2001 to 2004, Ichiro had more hits (924) than anyone in history over any four-year period, breaking the record of 918 that Bill Terry accumulated from 1929 to 1932; Terry, however, played in 34 fewer games than Ichiro during their respective four-year spans. He would later surpass his own mark by recording 930 hits from 2004 to 2007. During one 56-game stretch in 2004, Ichiro batted over .450. By comparison, Joe DiMaggio batted .408 during his record-setting 56-game hitting streak. Ichiro batted over .400 against left-handed pitching in 2004.

As of 2001, Ichiro had deals with the US company golfwear company Cutter & Buck, Upper Deck trading card company, and sporting goods company Majestic Athletic.

Ichiro finished his second year in American baseball with 208 total hits, making him the first Mariners player ever with two consecutive seasons of 200+ hits. He got off to a hot start in 2002, but a late-season slump drove his batting average down to .321, 29 points below his batting average as a rookie. He was the fifth player in MLB history to start a career with two 200-hit seasons. Ichiro finished the season second in the AL in hits, fourth in batting average, and fourth in steals. Ichiro led the major league All-Star balloting for the second straight year. Although the Mariners had a 93–69 record, that was good for only a third-place finish in the competitive AL West.

Ichiro’s father, Nobuyuki, handled Ichiro’s finances early in his career until, in 2002, due to Nobuyuki underreporting Ichiro’s income, Ichiro was saddled with a significant bill for unpaid taxes. The scandal cost Ichiro an undisclosed amount of money and caused him great embarrassment. This incident, along with Nobuyuki’s relentless training and unforgiving attitude toward his son, caused their relationship to collapse. Subsequently, Ichiro’s finances have been looked after by his wife Yumiko.

In 2003, Ichiro became just the third player in history to begin his career with three 200-hit seasons, by garnering 212. He again finished in the top ten for hits, batting average, steals, and runs, and, again, a late season slump brought his average down almost 40 points (to .312). Ichiro was elected to his third All Star game in the three years he had been in the league, and he was again the vote leader in both leagues. However, the second-place Mariners again fell short of the playoffs.

Ichiro’s agent, Tony Attanasio, described his client’s status: “When you mail Ichiro something from the States, you only have to use that name on the address and he gets it [in Japan]. He’s that big.” Ichiro’s status in Japan fueled interest in Major League Baseball in Japan, including the $275 million broadcasting rights deal between MLB and Dentsu Inc. in 2003.

Ichiro had his best offensive season in 2004, highlighted by his breaking of George Sisler’s 84-year-old record for most hits (257) in a season. An increase in games played benefited Ichiro, as he accumulated only 251 hits through the first 154 games of the season. Ichiro recorded 50 hits in four different months of the year (September and October are combined by MLB for this computational purpose), becoming the first player ever to have four in a season. With 51 hits in August 2001, Ichiro joined Pete Rose as the only players with five 50-hit months in a career.

While he is known for his hitting ability, he did not draw many walks. In 2004, when he set the single-season record for hits, his low walk total (49) led to him being on base a total of 315 times. It was the 58th-most times a player has reached base in a season and short of the major league record of 379 set by Babe Ruth in 1923.

In 2005, Ichiro had his second worst year in his MLB career to date, collecting only 206 hits (the lowest total of his career to that point). However, he reached the plateau of a .300 batting average, 100+ runs, 30+ steals, and 200+ hits for the fifth straight season. That allowed Ichiro to become the first player to collect 200 hits per season in each of his first five years in the Major Leagues. Only Willie Keeler, Wade Boggs, Chuck Klein, Al Simmons, and Charlie Gehringer had had five consecutive 200-hit seasons at any point in their careers. During the season, he accumulated 1,000 career hits, reaching the career milestone faster than any other player in MLB history. Ichiro hit a career-high 15 home runs. In the off-season, Ichiro played himself in Furuhata Ninzaburō, a Japanese Columbo-like TV drama that he loves. In the drama, he kills a person and is arrested.

Ichiro played for the Japan national baseball team in the inaugural World Baseball Classic in March 2006. During 15 March Japan-Korea game Ichiro was booed by a few spectators during every at-bat, reportedly in response to a previous statement that he wanted “to beat South Korea so badly, that the South Koreans won’t want to play Japan for another 30 years.” That, however, was an incorrect translation mostly spread to the public through ESPN. Ichiro was variously quoted as saying “I want to win in a way that the opponent would think, ‘we cannot catch up with Japan for the coming 30 years’. We should not merely win the games.” Japan would later beat Korea in the playoffs and win the tournament after defeating Cuba in the finals, 10–6. For the tournament, Ichiro had twelve hits including a home run, seven runs, and four stolen bases.

Ichiro’s 2006 season got off to a disappointing start, with the outfielder hitting as low as .177 in the season’s third week. He quickly rebounded, finishing the season with a .322 average (sixth in the AL and 11th in the majors). Ichiro’s 224 hits led the majors, and he recorded 110 runs and 45 stolen bases. Ichiro was caught stealing only twice in 2006 for a 96% success rate. His 1,354 career U.S. hits topped Wade Boggs’s record for the most hits in any six-year period. In his sixth year in the majors, Ichiro collected his sixth Gold Glove Award, and a sixth All-Star Game selection. He also won a Fielding Bible Award as the best fielding MLB right fielder.

Ichiro began wearing high stocking baseball pants in the 2006 World Baseball Classic.

When he first came to the United States, he especially enjoyed trips to Kansas City to talk with former Negro Leagues star Buck O’Neil. When O’Neil died in 2006, Ichiro sent a very large memorial wreath to the funeral service. The following year, he visited the Negro Leagues Baseball Museum while on a road trip to Kansas City, and made what, as of 2016, remains the largest contribution ever made to the museum by an active MLB player.

On 10 July 2007, he became the first player to hit an inside-the-park home run in any MLB All-Star Game after an unpredictable hop off the right field wall of AT&T Park in San Francisco. It was the first inside-the-park home run of Ichiro’s professional career. Ichiro was a perfect 3-for-3 in the game and was named the Most Valuable Player in the American League’s 5–4 victory.

2007 marked the end of Ichiro’s second contract with the Mariners, and he initially told MLB.com that he would likely enter the free agent market, citing the team’s lack of success in recent years. However, Ichiro signed a five-year contract extension with Seattle in July. The deal was reported to be worth $90 million, consisting of a $17 million annual salary and $5 million signing bonus. The Associated Press reported that Ichiro’s contract extension defers $25 million of the $90 million at 5.5% interest until after his retirement, with payments through 2032. Other provisions in Ichiro’s contract included a yearly housing allowance of more than $30,000, and four first-class round-trip tickets to Japan each year for his family. He was provided with either a new Jeep or Mercedes SUV, as well as a personal trainer and interpreter.

On 29 July 2007, Ichiro collected his 1,500th U.S. hit, the third fastest to reach the MLB milestone behind Al Simmons and George Sisler. Ichiro had 213 hits in 2008, his eighth straight 200-hit season. This tied the 107-year-old record set by Wee Willie Keeler. Typically, Ichiro was among baseball’s leaders in reaching base on an error (14 times in 2008, more than any other batter in the AL), and in infield hits (his 56 were the most in the majors). Ichiro has amassed more than 450 infield hits in his U.S. career. Detroit third baseman Brandon Inge told The New York Times, “I wish you could put a camera at third base to see how he hits the ball and see the way it deceives you. You can call some guys’ infield hits cheap, but not his. He has amazing technique.” In May 2008, Ichiro stole two bases, giving him a career total of 292, surpassing the previous Seattle Mariners team record of 290 set by second baseman Julio Cruz. Cruz, who now does Spanish-language broadcasts of Mariners games, was watching from the broadcast booth as Ichiro broke his record.

On 29 July 2008, Ichiro became the second-youngest player to amass 3,000 top-level professional hits (1,278 in Japan + 1,722 in the U.S.) after Ty Cobb. He also became just the second Japanese professional to get 3,000 hits. (Nippon Professional Baseball’s record holder is Isao Harimoto, with 3,085 hits).

By 2008, it had emerged in the media that Ichiro was known within baseball for his tradition of exhorting the American League team with a profanity-laced pregame speech in the clubhouse prior to the MLB All-Star Game. Asked if the speech had had any effect on the AL’s decade-long winning streak, Ichiro deadpanned, “I’ve got to say over 90 percent.” Minnesota first baseman Justin Morneau describes the effect: “If you’ve never seen it, it’s definitely something pretty funny. It’s hard to explain, the effect it has on everyone. It’s such a tense environment. Everyone’s a little nervous for the game, and then he comes out. He doesn’t say a whole lot the whole time he’s in there, and all of a sudden, the manager gets done with his speech, and he pops off.” Boston’s slugger David Ortiz says simply, “It’s why we win.”

In July 2009, while in St. Louis for his ninth All-Star appearance, Ichiro made a trip to Sisler’s grave. He later told reporters, “There’s not many chances to come to St. Louis. In 2004, it was the first time I crossed paths with him, and his family generously came all the way to Seattle. Above all, it was a chance. I wanted to do that for a grand upperclassman of the baseball world. I think it’s only natural for someone to want to do that, to express my feelings in that way. I’m not sure if he’s happy about it.”

Ichiro was named #30 on the Sporting News’ 2009 list of the 50 greatest current players in baseball, voted upon by a 100-person panel of experts and former stars. In May and June, Ichiro surpassed his own franchise record with a 27-game hitting streak. Ichiro went on to record 44 hits in June 2009, his 20th career month with 40 or more hits. The previous players to have accomplished this were Stan Musial in the NL and Lou Gehrig in the AL.

On 26 September 2009, Ichiro was ejected from a game for the first time in his professional career. Arguing that a strikeout pitch from Toronto’s David Purcey had been outside, Ichiro used his bat to draw a line on the outer edge of the plate, and was immediately tossed by umpire Brian Runge. He was the only Mariner to be ejected from a game all season. The ejection may have hurt Ichiro’s chances regarding an esoteric record: the longest playing streak without going hitless in consecutive games. Ichiro’s stretch was at 180 games, the longest in the majors since Doc Cramer went 191 consecutive games without back-to-back 0-fers in 1934–35. Ichiro went hitless in the following afternoon’s game.

Ichiro again led the majors in hits in 2009, with 225. In spite of hitting ground balls at a rate of 55 percent, he grounded into only one double play all season, in 15 April game, his first game played in 2009. He won his second Fielding Bible Award as the best fielding right fielder in MLB.

Ichiro’s 32 career leadoff home runs rank ninth all time. Nevertheless, in 2009, Ichiro told The New York Times:

After playing in the season opener against the Oakland Athletics, Ichiro became eligible for Hall of Fame consideration, by playing in his tenth MLB season. On 5 June 2010, Ichiro scored his 1,000th career MLB run against the Angels on Franklin Gutierrez’s RBI groundout. He is the third Mariner in history to reach that milestone. On 1 September 2010, Ichiro also collected his 2,200th hit, a leadoff infield single against Cleveland Indians pitcher Josh Tomlin.

Ichiro won his tenth consecutive Rawlings Gold Glove Award in 2010, tying Ken Griffey Jr., Andruw Jones, and Al Kaline, and trailing only Roberto Clemente and Willie Mays (twelve each) for major league outfielders. Ichiro also won his second consecutive and third overall Fielding Bible Award for his statistically based defensive excellence in right field, as the only right fielder to have so far received multiple Bible awards. Jason Heyward subsequently equaled Ichiro with his third Bible in 2015; thereafter Mookie Betts promptly became the third right fielder to achieve this distinction in 2018, on three consecutive awards.

On 2 April 2011, Ichiro broke the Seattle Mariners’ all-time career hits record with his 2,248th hit in the 9th inning versus the Oakland Athletics, overtaking the team’s previous leader Edgar Martínez. 2011 marked the first time in Ichiro’s 11 seasons that he failed to make the all star team. He batted under .300 (.277) before the all star break for the first time in his career. On 10 July, manager Eric Wedge did not start Ichiro, ending his then-major league-best active streak of 255 consecutive starts. Ichiro followed with an 11-game hitting streak, but Wedge noted “it’s not that easy to give that guy a day off” due to Ichiro’s iconic stature. On 22 August, Ichiro hit his 35th career leadoff homer, tying him for 6th place with Bobby Bonds. Ichiro finished the season batting a career-low .272 with 184 hits, the first time in his 11-year MLB career he did not record 200 hits. It was also his first season not playing in the All-Star game, as well as his first season not winning a Gold Glove.

On 18 March 2011, Ichiro donated ¥100 million ($1.25 million) to the Japanese Red Cross for earthquake and tsunami relief efforts.

On 19 June 2012, Ichiro led off a game against the Arizona Diamondbacks with a single to center field, the 2,500th hit of his MLB career. Ichiro reached the milestone in the fourth-fewest games in major league history, after Al Simmons, Ty Cobb, and George Sisler. In a 13-inning road loss to the Oakland A’s on 8 July, Ichiro was placed second in the batting order and responded by going 2 for 6 to bring his season batting average to .261 heading into the All-Star break. In the previous night’s game, Ichiro recorded two hits to break a career-worst 0-for-23 hitless streak. Ichiro had also been tried at the three-spot in the batting order during a season for which he earned $18 million. Former teammate Jay Buhner stated he felt Ichiro was the recipient of too much blame for the Mariners’ difficulties but “at the same time, they need help desperately.” Buhner stated that if Ichiro were awarded a three-year contract extension for somewhere between $35 million and $40 million, “I’d vomit. I mean, really, no offense. No offense, we’ve got to get this organization turned around. You can’t be spending all the money on one guy.”

Ichiro approached the Mariners to ask for a trade at midseason in 2012, as he felt guilty for taking a roster spot from a younger player while his team was in a rebuilding process. His first choice was to play for the New York Yankees. The Mariners traded him to the Yankees for minor league pitchers D. J. Mitchell and Danny Farquhar on 23 July. Seattle also received cash in the trade. Ichiro left Seattle hitting .261 with a .288 on-base percentage (OBP), four home runs, 28 RBIs and 15 stolen bases in 95 games. His first game as a Yankee was played the night of the trade, at Safeco Field against the Mariners. Before the trade was consummated, Ichiro agreed to the Yankees’ conditions, which stated that they would play Ichiro primarily in left field, bat him at the bottom of the lineup, and occasionally sit him against left-handed pitching. Ichiro would go on to hit safely in his first 12 games as a Yankee, tying a record set by Don Slaught. He wore number 31 during his tenure with the Yankees, as his traditional 51 had not been used since the 2006 retirement of Bernie Williams, who wore it while playing for the Yankees; the Yankees retired the number permanently in 2015.

Ichiro performed well in his first playoff appearance since the beginning of his career. Against the Baltimore Orioles in the 2012 ALDS, Ichiro ran home on a ball hit by Robinson Canó. Despite the ball beating him to the plate, Orioles catcher Matt Wieters had difficulty tagging Ichiro, who evaded multiple tag attempts by jumping over and around Wieters. In Game 1 of the 2012 ALCS, Ichiro hit his first career postseason home run; however, the Yankees lost the series to the Detroit Tigers in only 4 games.

On 19 December 2012, Ichiro finalized a $13 million deal for two years with the Yankees.

When Ichiro was traded to the Yankees in July 2012, longtime Mariners fan Ben Gibbard (of Death Cab for Cutie) posted his tribute song, “Ichiro’s Theme”, on his SoundCloud page. The previous year, The Baseball Project had released the tribute song “Ichiro Goes To The Moon” on their album Volume 2: High and Inside.

On 25 June 2013, Ichiro hit a walk-off home run against Rangers pitcher Tanner Scheppers with two outs in the bottom of the ninth inning. Earlier in the game, three of his teammates had led off the fourth, fifth, and sixth innings with home runs, so all of the Yankees’ runs in the game were provided by solo home runs.

On 21 August 2013, Ichiro collected his 4,000th professional career hit with a single off Toronto Blue Jays pitcher R.A. Dickey, becoming the seventh player in professional baseball history known to have reached the mark after Pete Rose, Ty Cobb, Julio Franco, Hank Aaron, Jigger Statz, and Stan Musial. It is quite possible that Jake Beckley and Sam Crawford may have also produced 4,000 hits, but data for some of their minor league seasons is missing.

On 10 July 2014, Ichiro collected his 2,800th MLB hit off of Cleveland Indians pitcher Scott Atchison in the top of the eighth inning at Progressive Field. On 9 August 2014, Ichiro hit a single in a game against the Astros to pass George Sisler on the all-time hit list with his 2,811th hit. Ichiro had previously broken Sisler’s single season hit record in the 2004 season.

On 23 January 2015, Ichiro agreed to a one-year, $2 million contract with the Miami Marlins. The Marlins originally planned for him to be their fourth outfielder, but he finished the season with 439 plate appearances due to team injuries—primarily Giancarlo Stanton, who suffered a season-ending injury on 26 June. On 25 April, Ichiro scored his 1,310th major league run, which, combined with the 658 runs he scored in Japan, surpassed the record for runs scored by a Japanese player set by Sadaharu Oh. On 18 June, he was batting .294 after playing in 64 of the Marlins’ 68 games, but his average fell to .229 by season’s end. On 14 August at Busch Stadium, Ichiro singled off St. Louis Cardinals starter John Lackey to earn his 4,192nd top-level hit, passing Ty Cobb. On 29 July, Ichiro recorded his 2,900th major league hit, against Washington Nationals pitcher Doug Fister. On 18 August, Ichiro had his first four-hit game since 2013. On 31 August, against the Atlanta Braves, Ichiro scored his 2,000th professional run when combining his runs scored in MLB (1,342) and in Japan’s NPB (658). On 5 September, Ichiro recorded his 100th right field assist in the major leagues. In the season finale against the Philadelphia Phillies on 4 October, he made his major league pitching debut, completing the final inning and allowing one run and two hits in a 7–2 loss. For the 2015 season, he batted .229/.282/.279 with 11 stolen bases.

On 6 October 2015, Ichiro and the Marlins agreed on a one-year, $2 million contract for the 2016 season. The deal also came with a $2 million club option for 2017. He stole his 500th career MLB base on 29 April 2016, against the Milwaukee Brewers, and led off the game with a single against Zach Davies to move ahead of Frank Robinson into 33rd place on the all-time MLB hit list with the 2,944th hit of his career.

After the 2016 season, the Marlins exercised their option on Ichiro’s contract for the 2017 season, and added an option for the 2018 season.

On 25 June, Ichiro (age 43 and 246 days) became the oldest player to start a game in center field since at least 1900, breaking the record previously held by Rickey Henderson. On 29 June, Ichiro became the oldest active MLB player when Bartolo Colón was designated for assignment by the Atlanta Braves, although Colon latched on with the Minnesota Twins a few weeks later. On 6 July, Ichiro hit two singles against the St. Louis Cardinals, bringing his hits total to 3,054 and surpassing Panamanian-born Rod Carew as the all-time leader in MLB hits among foreign-born players. Dominican born Adrian Beltre surpassed Ichiro as the foreign hits leader on 13 June 2018.

On 7 March 2018, Ichiro signed a one-year contract to return to the Mariners after several team outfielders were injured during spring training. On Opening Day, 29 March, against the Cleveland Indians, Ichiro became the 20th outfielder all-time to record 5,000 career putouts at the position. At 44 years old, he entered the 2018 season as the second-oldest active player in baseball, behind only Bartolo Colón.

On 2 October 2018, it was announced that Ichiro would be on the Mariners’ active roster when they opened the 2019 season against the Oakland Athletics in Japan. Ichiro was re-signed to a minor league deal on 23 January 2019.

On 20 March 2019, the Mariners opened the MLB season against the Athletics at the Tokyo Dome and Ichiro started the game in right field, becoming at 45 years old the second oldest position player (behind Julio Franco) to start for a team on its opening day. The next night, the Mariners again played the Athletics at the Tokyo Dome and Ichiro played in his final professional game. He went 0–4 at the plate and in the bottom of the 8th inning walked off the field to applause from his native-country crowd. Later in the day, Ichiro officially announced his retirement. He was the oldest active MLB player at the time.

2019 was Ichiro’s 19th season in the MLB, and including the 9 years he played in Japan’s NPB, Ichiro’s 28 seasons of playing in baseball’s top-tiered leagues eclipsed the record of most seasons played by a position player held previously by 19th century MLB player Cap Anson. (MLB pitcher Nolan Ryan, like Anson, also played 27 seasons, while NPB pitcher Kimiyasu Kudo played 29 seasons).
