Takeyama Yoshinao (YOS 1606) was born in Gifu prefecture in 1908 as Takayama Isao. 1941 Hagio Takahashi listed him as Joko no Retsu, whilst Kurihara Hikosaburo listed him in the following year as Chu Saku. He was, in short, a middle ranking competent smith
Takeyama Yoshinao is listed in Japanese sources such as Nihonto Meikan and Tosho Zenshu as a Rikugun Jumei Tosho. Smiths in the RJT scheme were given tamehagane with which to make traditionally made swords. The swords produced under this scheme are identified with a star stamp.
