A few more details about Takanofuji (Née Takayoshitoshi) and his incident of violence have appeared in the Japanese press and media.
The incident took place on August 31st, right after the YDC keiko-soken was over and Takanofuji returned to the heya. Apparently he was displeased with the tsukebito’s attitude, and hit him on the head once.
The victim, who is a Jonidan rikishi, was still around the heya on September 1st. However, it appears that Takanofuji followed up with some brutal keiko, and the following day, three low-rankers went AWOL. Chiganoura oyakata noticed that, contacted them, and learned about the incident. He immediately reported the issue to the Compliance Committee, and has already publicly apologized for the incident.
The victim does not wish to involve the police and intends to come back to the heya.
Takanofuji has admitted to the facts, and is currently in “disciplinary kyujo” through Aki, and restricted to the heya by his oyakata.
Shibatayama oyakata commented that “Following a series of workshops, to have the same sekitori act violently a second time is exceedingly regrettable. Chairman Hakkaku says the same”. The procedure established in such cases is for the Compliance Committee to investigate the matter, consider an appropriate punishment, and report to the board, which makes the decision. The standard for a violent sekitori is suspension for one basho, but this being a repeat offense, the odds are high that it will be more severe than that.
Takagenji’s response: “This is a real shame. I don’t know what the punishment will be, but if it will be permitted, I hope we will be able to continue to do sumo together”.
(Internet speculation points to Takamasaki being the victim. He is ranked in Jonidan, and has been officially reported as one of Takanofuji’s tsukebito back in Haru this year. However, none of this has been confirmed nor is likely to ever be).
