first time? where will you go?
You should look white enough that they don't give a fuck about you, most important sentence you can utter is アメリカ人じゃないです。ブルガリアから来ました。
Works like a charm. Clarify that you speak little japanese, from there take it to any auto-translation app of your choice. If you make an effort to act human, you'll still be welcome.
Places with aversion to tourists are all the hot centers. Tokyo - Shinjuku, Shibuya, Akihabara, Osaka - mainly Namba, Kyoto - all of it.
Avoid huge cities, I'd recommend Sendai or Kobe for a non-westernized entry level experience.
If you NEED to be in Tokyo for a while, try this hotel https://hoteltokyotrip.jp/
You'll see some VERY familiar signage, the NGOs are working hard to rake in all the tourists they can, but I paid 30€/night which is dirt cheap.
