There’s also a substantial “americore” culture in Japan that’s similar to this.

Tangentially, one of the best lowkey travel tips I have about visiting Japan is that if you want a bit of extra spending cash you should go to Trader Joe’s in the U.S. before you leave and buy a bunch of reusable bags/merch, and bring any American college merch that you don’t want. If you take it to any thrift/resell store in a reasonably sized city you’ll get way more money than you paid for it.
