Museum or other activities for people who are interested in stuff like bones, insects, fossils?

Hey there,
I'll be in Japan from 2nd to 22th December. I'll be staying in Kyoto, Kanazawa and Tokyo.

What I've found so far:
• Ishikawa Insect Museum close to Kanazawa
• Fukui Prefectural Dinosaur Museum in Fukui, day trip from Kanazawa
• Parasitological Museum in Tokyo
• National Museum of Nature and Science in Tokyo
Most of them seem to have english texts as well so I won't have to Google Translate everything which is awesome.

But I thought maybe someone here might have more suggestions?

Shops regarding those topics are great, too. (I know that I might stumble upon skulls or preserved specimen at flea markets.)
I most likely won't buy anything, as I don't want get in trouble with "Zoll" (customs?) when I return to Germany. But I think looking around and maybe talking to someone whos interested in such stuff would be a really nice experience aswell! 🙂
