The Japanese government officially asked internet service providers in Japan to block access to three pirated manga websites including Mangamura in April 2018.
Police stated a man believed to be Adachi contacted Fukuoka police earlier in August stating he wanted to turn himself in.
According to Japan’s Content Overseas Distribution Association (CODA), between September 2017 and February 2018, users accessed Mangamura about 620 million times.
Police in Fukuoka arrested Wataru Adachi (37) on Saturday on suspicion of uploading unauthorized images from Eiichiro Oda’s One Piece manga to the Japanese manga piracy website Mangamura in May 2017.
