HELP! Japan Figure Shopping

In 3 weeks, I’ll be visiting Japan for the first time, and I’m planning to do a lot of anime figure shopping in Tokyo.

These are some of my all-time favorite series that I’d love to find merch from. I know a lot of them are older, so I’m not expecting it to be easy.

I’m planning to check out Mandarake (Osaka + Akihabara), Lashinbang, and A-Stop.

Would really appreciate any recommendations for other shops/areas where I might have a chance of finding merch, especially for the titles in bold.
