In 1980, as the result of a conflict between Ōtsuka and the Wadōkai organization over personal withdrawals from the organization's bank accounts, he stepped down as head of the Wadōkai. Eiichi Eriguchi took over his place within that organization. On 1 April 1981, Ōtsuka founded the "Wadōryū Karatedō Renmei." ("Renmei" means "group" or "federation.") After only a few months, he retired as head of this organization. His son, Jiro Ōtsuka, took his place. On 29 January 1982, Hironori Ōtsuka died, and in 1983, Jiro Ōtsuka succeeded him as grandmaster of Wadō-ryū. The younger Ōtsuka changed his name to "Hironori Otsuka II" in honor of his late father. In 1989, Tatsuo Suzuki founded the third major Wadō-ryū organization, "Wadō Kokusai" (Wadō International Karatedō Federation; WIKF). ("Kokusai" means "international.")
