There are quite a few museums in Tokyo, we only made it to two on different days. The first was visited was the Tokyo National Museum. We took the train into town using our JR passes. At the station we managed to spot a desk with helpful people selling tickets to all the museums in the area. I pointed my phone at the handwritten signs to work out exactly what they were selling. We then walked through the park in the rain to the museum armed with our tickets. My Hong Kong umbrella served me well.
