Giant pumpkins with insect-like markings are some of the most popular photo opportunities of Naoshima (since inside the museums guests are to refrain from photography).
Walking around the island you will see modern touches even in the oldest of Japanese tradition, like this mud wall:
The most simple and subtle of pieces were tucked away, and even ordinary objects can become art, like this portrait made of yarn on the side of a building.
Another place I was really excited to go to was "I ♥ 湯", an onsen (hot spring bath). The kanji 湯 means "hot water" and is pronounced yu, and thus a delightful pun was born. The inside and outside of this onsen are decorated in a unique manner that might remind you of all the delightful treasures you find in your grandmother's basement.
