These five Japanese houses will keep you fit
In general, the Japanese are a pretty healthy people. But besides eating healthy, some Japanese intertwine exercise with architecture. These five Japanese houses are designed to make exercise unavoidable for their inhabitants. One house has a built-in rock climbing wall, another features a mini-golf course, and another house has floor-to-ceiling sliding poles and undulating concrete floors. If you’re ever a guest in one of these houses, be prepared to break a sweat.
