Hiroshi Sambuichi‘s Naoshima Hall located in the village of Honmura, is probably my favorite building (really a couple of buildings and a garden) on Naoshima.
If you visit Naoshima in the near future, you may find it closed, as the main room is only open for special events outside of the Setouchi Triennale. So, I thought you’d like to see what it looks like. There it is.
Note that while you can’t enter that part of the building, it’s still worth a visit.
You can see and read more about Naoshima Hall in this post (just follow the link).
