In the 1980s, led by Shogen Okabayashi ("Okabayashi Shogen", born 1949-2018), who was sent by the elderly Hisa to train under the headmaster, the Takumakai made a move to implement the forms for teaching the fundamentals of the art as originally established by Tokimune Takeda. This move upset some preservers of Hisa's original teaching method, leading to the formation of a new organization called the Daibukan, founded by a long term student of Hisa, Kenkichi Ohgami ("Ōgami Kenkichi", born 1936). Later, in order to implement greater changes to the curriculum, Okabayashi himself chose to separate from the Takumakai and formed the Hakuho-ryu.
