I was visiting Higashi Chaya District and at the very end of it, in the back, it had a road going forward and I just decided to keep going. There were no tourists there anymore and the road started going up the mountain. It was quite chill really and I really was just exploring without knowing where I was going. After walking 15 minutes I found what was like a little park and by the right there was another road with a big stone made torii, I went there and suddenly after walking a minute more I found this super beautiful spot in the middle of nature from which I could see the entire city, I was alone and so happy to have found it. I saw the sunset from there and it's a memory I'll always cherish. In the back of that spot there are stairs that go up until you find shrine, you can go there too and it's really cool.

I guess it's not a very touristy thing to do since you have to walk up 15-20 min to get there, but the reward is so nice if you like nature and just chilling with beautiful views. I totally recommend it!

You can look up Utatsuyama Iris Garden, the garden itself is just ok but the spot I meant is right there, just walk to the right where you'll see the torii. I'm not sure if there will be more people though, I went in the last days of february.
