While this house might not be so interesting for those used to Jacobean and Victorian architecture, it's an unusual house to find in Tokyo. Formerly the mansion of the Mitsubishi family, the attractive house with porches sits on a large block of land near Ueno Park. One of the most interesting parts is the free-standing billiards room, built like a Swiss Chalet. The main house leads directly into a traditional Japanese house, which is quite surprising. Be aware that you need to take off your shoes to tour the houses and you can't take photos inside. There are some coin lockers at the ticket office for storing large bags and tickets are reasonable. The Japanese house has a small tea room with snacks. You can also bring your own food and drinks to enjoy at tables in the gardens.
