I went to Kyoto last year during what can be considered peak season. My accommodation was quiet central. I have to say I didn't have a problem with overturism. Sure if you visit what everyone markets on Instagram there are flocks of tourists everywhere. If you just randomly explore the city, you can find equally beautiful places that lack tourists and in my opinion are far more charming.

I think the problem is that since Japan has been trending on social media, everyone goes to the same 3 temples, eats at the same 5 restaurants and so on. And social media sure doesn't help in spreading the tourist flux evenly.
