Underrated spots in Tokyo?

My wife and I are visiting Tokyo soon and we’ll be staying in Komagome.

We already went to the usual spots last year (Shibuya, Shinjuku [I proposed at Naitomachi!], Asakusa, etc.), but I’m curious, what are some underrated spots in Tokyo that tourists usually miss?

Could be anything:

• cool neighborhoods to walk around
• hidden food spots
• quiet temples/shrines
• small parks or viewpoints
• unique cafés or shops

Something that makes you a bit local I guess.

Would love to hear your recommendations!
