More places in Tokyo than the most known ones?

Disclaimer: i did search the sub, i have made a lot of research, i just want to collect more ideas and its okay if it repeats.

I want more places to explore in Tokyo. Its not about less tourists, or "off the beaten path", or less known, just something that isnt the usual main points of interests. Something thats not on top pages when you google what to do in Tokyo.

I qant cool neighbourhoods, shrines/temples, parks etc. No bars or shopping.
