The third headmaster of the Tenshinsho Jigen Ryu Hyōhō was Terasaka Yakuro Masatsune (赤坂 弥九郎 政雅, 1567- 1594), also known by his Buddhist dharma name, Zenkitsu (善吉, also read Zenkichi).
In 1963, the Tenshisho Jigen Ryu would see a revival under the 27th headmaster, Ueno Yasuyuki Genshin (上野 靖之 源心, 1913- 1972), when he began instructing at the Shobukan in Asakusa, Tokyo until his death in 1972 [REF].
