Visiting Japan and struggling to find somewhere to buy digimon

Hi. Off to Japan next week (like half of the world it seems).

I do know Japan pretty well but I’m struggling to find somewhere that sells Digimon merch reliably like the Pokémon Centre does for Pokémon. There is a Bandai store but it seems thin on the ground for Digimon stuff.

Just wondering if anyone local knows any hidden gems for Digimon goods in Tokyo, Osaka or Fukuoka.

Thanks :)
