アイスリボン
On December 14, 2011, Ice Ribbon's founder Emi Sakura announced that she was leaving the promotion for "personal reasons" following the January 7, 2012, event in Sendai. Following Sakura's departure, Hikaru Shida and Tsukasa Fujimoto took over the training duties at the Ice Ribbon dojo. The initial training program, from which one can graduate to become an official Ice Ribbon trainee, is currently run by Ice Ribbon's Referee Mio Shirai and ICE ribbon's own Tsukushi. During 2012, Ray, Sayaka Obihiro, and Ice Ribbon originals Hikari Minami and Riho also left Ice Ribbon, while Dorami Nagano went inactive to concentrate on her studies. To combat the decreasing number of wrestlers on its active roster, Ice Ribbon introduced the first six wrestlers trained by Hikaru Shida and Tsukasa Fujimoto: Eri Wakamatsu, Fumiko Sato, Risa Okuda, Rutsuko Yamaguchi, Oshima Kujira and Shoko Hotta. Wakamatsu and Hotta, along with Ayano Takeda and Hiroko Terada, two other Shida and Fujimoto trainees who debuted before the end of 2012, all had quit their professional wrestling careers by April 2013. Risa Sera (renamed from Risa Okuda) is still active.
