Gokaisho is part of Naoshima’s Art House Project.
It’s not my favorite art house, but it’s not unpleasant either, especially when you have it all for yourself.
Also, the last time I went, in April, the actual camelia tree on-site was in bloom (only one flower, but that’s better than none). Nice.
If you want to know more about Gokaisho and the Art House Project in general, may I advise you to read this page?
