Io Shirai
On May 23, 2012, Nosawa and former girlfriend Io Shirai were arrested at the Narita International Airport in Narita, Chiba upon their return from Mexico to Japan under suspicion of trying to smuggle 75 grams of marijuana, hidden inside paintings of the two, into the country. On July 9, Mexico-based Japanese wrestler Takuya Sugi held a press conference and confessed to planting the drugs on Shirai and Nosawa. According to Sugi, Masahiro Hayashi, who worked as a liaison between AAA and Japan and who had a personal grudge with Nosawa, had promised him a contract extension with AAA in exchange for the deed.
