My point is just that Japanese homes are not built with any ductwork at all, aside from a vent above the stove and in the shower/bathroom. A "whole-home" device

My point is just that Japanese homes are not built with any ductwork at all, aside from a vent above the stove and in the shower/bathroom. A "whole-home" device like those you linked would require installing air ducts to every room, and the homes just aren't designed for it.
- throw0101a 7y agoActually you wouldn't have to duct the whole house: humidity does not concentrate like heat does, but rather diffuses. So even if you only have a dehumidify one part of the house, the moisture level would level average out (over a given period of time). Though this does depend slightly on air circulation, but a couple of tubes (e.g.) connecting floors would help balance things out. Japanese companies produce many quality products that deal with indoor air quality: * https://news.panasonic.com/global/topics/2017/53539.html https://news.panasonic.com/global/topics/2017/53539.html There are stand alone units as well: * http://www.survivingnjapan.com/2012/08/a-guide-to-dehumidifiers-in-japan.html http://www.survivingnjapan.com/2012/08/a-guide-to-dehumidifi... All that said, a proper building envelope is the first thing that needs to be done. Don't know enough JP codes and construction techniques to comment on that though.
