Open Tuesdays to Sundays (9:00 - 6:00 April - Sept, 9:30 - 5:00 Oct
- Mar) the building is typical of any other modern centre in Japan.
I paid the 200 yen and entered.
Inside I asked if I could take photos. To my disappointment I
was told that I couldn't.
However the display had the best catalogue of any sword museum I'd visited (quite a few).
I'm not sure how many Nihonto (Japanese swords) are usually displayed
here. If you are at Okayama and want to see more swords, in a great
museum, I strongly suggest visiting Osafune.
Okayama is west of Osaka, with Himeji about half way.
Here is a map of the Okayama and the location of the museum.
