For the past 4 years, his access to the website has been suspended for a total of 6 times, not only for his violation of the protocol but also for the defamation of the participants and well-known figures including the author of a bestselling book (Eigo-mimi), Kiyoshi Matsuzawa.
He is also notorious for sending spam e-mails from his former company, IBS, and widely accused for constituting an invasion of privacy by revealing private e-mails sent to him from Matsuzawa, and a famous voice trainer, Kazuhiro Takemura.
