For non-Japanese speakers, this museum is only interesting for the architecture of Tadao Ando. We walked through the path, took a couple of pictures of the building and went right to Boukeitei, the adjacent traditional house which is free to visit.
Went for the Hana to Yume exhibition. It was a really nice exhibition over three rooms. The entrance fee was reasonable and it was easy to get to the museum by public transportation.
For long term visitors of Himeji, I recommend visiting Himeji's Museum of Literature. The Forest of Words display was enjoyable for me. The museum also has historical information about the Harima area & Himeyama, the mountain which Himeji Castle is built upon, which began as a small fort.
No translations are available, so this museum is a complete waste of time for non-Japanese speaking tourists. The only interesting exhibit I saw was the temporary special exhibition, which requires a separate ticket. There’s a small Japanese-style home, but it’s not worth a trip. Worst of all, the building itself looks like a prison. (July 2019)
