Bleach Japan was a Japanese non-profit organization and yakuza front organization which was founded in 2004 by Ryo Aoki and Hajime Ogasawara with the objective of "bleaching" Japan's "gray zones" (hubs of semi-illegal activity such as prostitution and gambling) "white". Bleach Japan's anti-corruption and anti-vice agenda took on right-wing populist and social conservative undertones such as targeting sex workers, foreigners, and the homeless. Aoki left the movement to enter politics with a run for the House of Councilors in 2010, and Ogasawara became Bleach Japan's new leader. In spite of its active campaginging against nightlife establishments and other semi-illegal businesses, Bleach Japan served as a front group for the Omi Alliance, as Aoki ordered Omi members to join the group as both muscle and to intimidate anyone in the group who would question him. In 2019, Ogasawara was murdered on Aoki's orders after failing to reveal the Ijin Three's counterfeiting operation at Otohime Land in Yokohama, and Aoki personally led the effort to eradicate the majority of nightlife operations in the Isezakicho district. However, the joint dissolution of the Omi Alliance and the Tojo-kai left Bleach Japan without its criminal backing, and, on the eve of Aoki's successful election campaign, the press revealed his past as yakuza boss Masumi Arakawa's son. Disgruntled Bleach Japan chapter leader Sota Kume responded by murdering Aoki, but not before the revelations of Aoki's corruption brought down several top law enforcement personnel who were associated with him and his movement.
