Re: yamato ryu
The translators misread the name. It is actually Daiwa-ryu. The author is also known as Sato Kinbei. He claimed myriads of menkyo kaiden. 14, if I recall. Among them is Daito-ryu. I forget who his teacher was. He also claimed a surfeit of certificates in Chinese martial arts. He made an amalgam of all he studied. Thsts his Daiwa.
