I like the Jungle store in Los Angeles a lot.
And I also like the internet since I can get good prices for things like figurines. And Amazon is a godsend for comics and TV shows. But those are not cities, lol...
but yeah if you want a city with a lot of anime stores try Los Angeles, there are a ton. The only problem is that most of them are just warehouses for online stores and they'll self destruct if you try to go to one in person to shop
Not the best city for Japanese media, but we do have some stuff.
