Keizo Sakurai or 桜井恵三◆aRZpjQmYwQ (May 1944-) is allegedly an English-Japanese interpreter based in Saitama, Japan. He has been continually promoting his self-produced English education materials at 2 Channel where such promotions are strictly prohibited.
Since 2004, his access to the website has been suspended for a total of 11 times (as of October, 2010), 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[1], and widely accused for constituting an invasion of privacy by revealing private e-mails sent to him from Matsuzawa[2], and a famous voice trainer, Kazuhiro Takemura[3]. His access to the Internet was temporarily disabled after a number of his illegal activities, and enraged Sakurai has sued his Internet provider Nifty for intrusion of privacy[4].
