TAKEBE Katahiro (1664-1739) was a famous mathematician in the Edo period in Japan and was an outstanding pupil of SEKI Takakazu (?-1708) who was an authority on Japanese traditional mathematics. The Enri Kohai-jutsu has been thought to be a book by TAKEBE. One of the manuscripts is preserved in the Hayashi collection of Tohoku University's library (call number : Hayashi 911) and there is another manuscript in the Boso sugaku collection of Natural History Museum and Institute, Chiba (call number : Boso sugaku-collection No. 178). Differences can be found between them. They are especially different in the second half.

The Takuma School is one of the schools of Japanese traditional mathematics in the Kansai district. Toshikiyo KAMATA (1678-1747) is the head of the third generation of the Takuma School. The Takuma-ryu Enri preserved in the library of the University of Tokyo consists of five volumes and the first two volumes have been thought to be KAMATA'S works. The Takuma-ryu Enri vol. 1 by Toshikiyo KAMATA is especially famous for the calculation of pi. The Takuma-ryu Enri Hijutsu is in the same library and one theory holds that its author is Toshikiyo KAMATA too. The Kohai-mitsujutsu Kigen preserved in the Ogura collection of Waseda University's library is composed of two volumes. The first volume is a variant text of the Takuma-ryu Enri Hijutsu and the second is an alternate version of the Takuma-ryu Enri vol. 2. At the end of the Kohai-mitsujutsu Kigen vol. 2 the description "Yoshikazu MATSUOKA respectfully has written this from 1792 to 1804 " can be found. Yoshikazu MATSUOKA (1737-?) is the head of the fifth generation of the Takuma School. By this fact and other reasons it is probable that the author of the Takuma-ryu Enri vol. 2 and the Takuma-ryu Enri Hijutsu is not Toshikiyo KAMATA but Yoshikazu MATSUOKA.
