Some time ago, Meik Skoss of Yagyu Ryu and Toda Ha Buko Ryu made a post where he said he wouldn't accept a student who had tatttoos. He said that he inspects the applicant first (and his wife checks the females). Is this generally true of koryu teachers? Including those in Japan? Will they refuse a student with tattoos? If so, why exactly? Is it because they would suspect them of being connected to Yakuza?
