The subtitle of Japan Modern may be a bit misleading - these new ideas may no longer be new. The book was first published back in 2000 so many of the homes were products of the late 1990s.
I'm not enough of an architecture buff to know just how much things have moved on - if it all. But I can say that the ideas and homes profiled are worth a look.
All in all an interesting glimpse into cutting edge ideas from late in the last century. It leaves me looking for a more up-to-date book with more recent homes.
