I’m not sure how well that works when the ground keeps moving. Some places manage it to a degree, but the cultures that come to mind (Aztec) weren’t on land as shaky as Japan.

I'd reconsider that. The Aztec culture was spread over much of central and southern Mexico, a region known for having an abundance of tectonic and also even volcanic instability. Even the case of their capital is almost amusing in that it was built over sand and mud, on a lake, in the middle of a valley severely prone to very heavy earthquakes.
