Astro Boy Merchandise In Tokyo

My dad is currently in Japan and I have him looking for a store that sells Astro Boy merchandise. He has already tried going Tezuka Osamu World in Tokyo but all of the locations there have closed down and he can't go to the one in Kyoto because it is too far away.So now I am wondering if there are any other stores in Tokyo that sell Astro Boy merchandise besides the closed down Tezuka Osamu world stores. I specifically looking for an Astro Boy plush toy. If anyone has an answer it's going to be on here. Thanks for helping me and my dad out!

Hi, you might want to check out akihabara since there are loads of anime/manga/computer related stuff there. It's virtually the otaku's capital of the world.

"Astro Boy" probably won't do. You should tell your dad to use "Tetsuwan Atomu" as that's the Japanese name for Astro Boy.
