Japanese character 里
In Japanese names, this character can (rarely) be read "satoshi". It is an uncommon Chinese/Japanese character on its own, and an infrequent radical (kangxi #166). It can be seen as a radical in the common kanji 理 and 量, used in meaningful words like: 理想 (ideals), 理論 (theory), 理性 (reason), 理科 (science), and 量 (quantity). "Satoshi" is a rare reading; more commonly it is read as "ri" or "sato". -source for Japanese character or symbol is https://en.bitcoin.it/wiki/Satoshi_(unit)
