I have a history question I am researchng concerning the explosion aboard the battleship Yamato, and was hoping that staff or docents at theYamato Museum might be able to help. Can you supply me with an e-mail address for the Museum?
You can call the Yamato Museum on this phone:

They don't have an official email to contact in English but maybe you could try filling this contact form:
If you can't write in Japanese, write in English and hopefully they will be able to get someone to help to reply.
