Where to buy Hanafuda and Karuta in Japan?

Hi! I’m visiting Japan next month, concretely Tokyo, Osaka, Kyoto and Takayama.

I wanted to buy some hanafuda cards and it’s garuta cause I love collecting card games from around the world but unfortunately I’m not sure where it could be a good place to buy them that is relatively near to the main touristic areas.

Any help would be appreciated!
