Kyoho scale - Kyohojaku

Japanese: 享保尺 - きょうほうじゃく

〘Noun〙 A carpenter's ruler (kanejaku) instituted by Shogun Yoshimune during the Kyoho era ( 1716-36 ). Measures had been inconsistent since the Middle Ages, but they were unified with a standardized standard of 303.65 mm, modeled after the ancient ruler at Kumano Shrine in Kii Province (Wakayama Prefecture). Later, surveyor Ino Tadataka combined this with the matashiro ruler (302.37 mm) used by carpenters to create the so-called compromise ruler (302.97 mm). This compromise ruler was approved by the Meiji government's Dajokan (Grand Council of State) and adopted as the official carpenter's ruler.

〘名〙享保年間（一七一六‐三六）将軍吉宗が制定した曲尺(かねじゃく)をいう。中世以降不統一だった尺度を、紀伊国（和歌山県）熊野神社の古尺を模して、三〇三・六五ミリメートルを原尺として統一したもの。のち測量家伊能忠敬は、木匠たちが使っていた又四郎尺（三〇二・三七ミリメートル）とこれとを折衷して、いわゆる折衷尺（三〇二・九七ミリメートル）を作った。この折衷尺が明治政府太政官の認可を得て正規の曲尺として採用された。
