He was barred from working in the entertainment industry temporarily by his entertainment agency, MTM Productions, and his comment was "I wish miniskirts were obliterated from the Earth." While he was barred, he did volunteer work such as carrying the wash and serving meals in a nursing home 3 days a week. On June 28, 2001, he announced his return to the entertainment world by saying, "Please give Masashi Tashiro one more chance." (もう1度だけ田代まさしを、よろしくお願い致します)
In July 2001 he appeared as a guest on television programs such as "Downtown DX," "Guruguru Ninety-Nine" (ぐるぐるナインティナイン) and "Mecha-Mecha Iketeru!" (めちゃ2イケてるッ!). He also returned as part of the regular cast in "Shimura Ken no Bakatono-sama" (志村けんのバカ殿様). To become a regular in another program, "HAMADA COMPANY Dangan! Heroes" (HAMADA COMPANY 弾丸!ヒーローズ), he was challenged to travel from Tokyo to Okinawa without being discovered by anyone. He lost the contest when he was found out in Kyoto and 100 pictures of him were taken, but the public liked his stunt and his popularity soared back.
On December 9, 2001, he was arrested for peeping through the bathroom window of a man's house near his home in Kita-senzoku, Ōta, Tokyo by Den-en-chōfu police. According to the police, the 32-year-old man who was being spied spotted Tashiro and ran after him for 300 meters wearing only a bath towel around his waist, eventually catching him and delivering him to the station. An eyewitness reported that Tashiro put on a cap like a ski cap, spoke loudly "Forgive me" (許してくれ, yurushitekure), "It was a misunderstanding" (勘違いだ, kanchigai da) when he was caught and there was a camcorder in the vicinity of the scene recording. He was released on bail without punishment.
However, he was arrested for possession and use of amphetamine on December 12, 2001. The seven police detectives carried out a home search in Tashiro's house as a corroborative investigation into his Peeping Tom incident and discovered a bag containing 0.4 ~ 0.9g of speed. Tashiro stated that, "I bought it", but how he used it was unknown because a syringe used to inject drugs was not discovered in the home search. He was detained as a suspect at the police station after his arrest until February 1 of the next year. As a result, he was dismissed by MTM Production on the same day because of the repeated scandals.
On December 28, 2001, he was prosecuted for the violation of Stimulant Drugs Control Law. He testified that, "I used drugs to get rid of stress and tension before appearing on a TV program" for the investigation by Tokyo District Prosecution Office. He also said, "I lived confined to the house and I began to worry. From about this April, I used it once every few days". According to an indictment, he warmed amphetamine over a fire and absorbed it in his home's video room. His first trial for drug use and other crimes was in Tokyo District Court on February 1, 2002. Judgement was given on the case in the same court on February 8, 2002, where he was found guilty. However, he was given 3 years suspended sentence of 2 years imprisonment.
In 2001, users of internet forum 2channel voted en-masse Tashiro as Time Magazine's Person of the Year. This act was soon dubbed the "Tashiro Festival" (Tashiro Matsuri, 田代祭) by 2ch users. 2channel programmers developed many scripts such as "Tashiro Cannon" (Tashiro-hō, 田代砲), "Mega particle Tashiro Cannon" (Mega-ryūshi Tashiro-hō, メガ粒子田代砲), "25 repeated blows Tashiro Cannon" (Nijū-go renda Tashiro-hō, 25連打田代砲) "Super Tashiro Cannon" (Chō Tashiro-hō, 超田代砲) to be able to vote repeatedly. "Super Tashiro cannon" was so powerful that it crashed Time's server. Afterwards, "Satellite Cannon -Tashiro-" was developed, but it was not deployed. Due to the votes of 2channel users, he got to the No. 1 position temporarily on December 21, 2001. However, Time's staff realized that something was unusual, and Tashiro was removed as a candidate.
