Japanese dual citizen tax residency

I'm in a weird situation. I'm a dual US/Japanese citizen (yes I know all about this), so from Japan's perspective I am a Japanese citizen. I am planning to work remotely for a US company for less than a year in Japan. Does this make me a tax resident of Japan? The money would never enter Japan – US company, payed into a US bank account.

All I can find is quotes that "you become a tax resident if you have a jusho or kyusho in Japan for more than 1 year", which will not be the case for me. This seems pretty clear to me, but everything in the english-speaking internet is written from the perspective of permanent residents who are _not_ Japanese citizens, and my Japanese tax/legal related reading comprehension is not that great..
