I've been looking at dome houses and found some pre-fab Japanese dome homes[1] that are certified by the Japanese "Minister of Land, Infrastructure, Transport and Tourism" [2].

They are packed less densely than I imagine most Japanese housing, but they are still quite small by western standards. 1: https://www.i-domehouse.com/case/project_house/plan_00004.html https://www.i-domehouse.com/case/project_house/plan_00004.ht... 2: https://www.i-domehouse.com/page03.html https://www.i-domehouse.com/page03.html
