ATS Japan supplies container houses using used containers and JIS-compatible new containers, with public material describing building-confirmation-ready options for homes, shops and offices, including two- and three-storey container buildings. It is relevant for buyers comparing container construction against regular prefab because the site publishes price references and invites pre-arranged visits.

Buyers should verify whether a project uses used or new units, which JIS or code route applies, and how foundation, insulation and transport are priced.
