Hey I just saw this thread - I'm going to be in Japan in 3 weeks! I was thinking about stopping in Kure (going to Hiroshima for two days for the anniversary), but I didn't know what to look for. From my limited research, it seemed as though there wasn't much WWII stuff to check out in Japan. This museum is definitely something I want to look into since I'm starting my trip at Pearl Harbor. It looks like everything is in Japanese only though. I'm on the museum's site now but I can't tell - do they have anything in English? Any audioguides?
I can't seem to figure out how to PM you/contact you directly, so hopefully you'll see this in time. I'm a newbie, so if anyone can help me get in contact with Boku4u, please let me know!
