Summer is a good time to visit the museum, and not just because these art and cultural institutions are particularly well air-conditioned. Most museums in Tokyo put on special programmes throughout summer, celebrating the warm season with everything from special guided tours to beer gardens.
One of the most active merrymakers is Takebashi's National Museum of Modern Art, which puts on an artsy festival until early October. It features tours for both adults and kids, special workshops related to the ongoing exhibitions, and food vendors where you can pick up some snacks and drinks to enjoy on the museum lawn.
