Teshima Art Museum (豊島美術館)

Part of the Benesse art site, this museum is absolutely breathtaking. No photos allowed inside. Teshima is a separate island to Naoshima (the art island you have probably seen). Book a time slot ahead and look at transport to coincide. Ferries only run a few times a day. We spent a lot longer than we thought here. You can leave luggage close to the port.
