I considered trying to incorporate a lot of ideas from this and build a place here in Japan, but the insurance side of it made things basically impossible, especially given how prevalent large earthquakes are here. That’s not to say there’s nothing to take away from it here, it’s just that certain materials and design choices shouldn’t be done here. There are a couple of earthships in Japan, but IIRC they’re not insured at all and every single one has to be approved by an independent architect and engineer or be in questionable legal status.
