In a small area right next to Kohata Station and the main Kyoto Animation office there's a few details that seems to have been shown at the main train station in Air.

Some kind of art which you can see on the left side in the screenshot.

This clock seems to be shown as well.

Inside Kohata Station there's one of these water faucets. The station itself is not the same as in the anime though. It's supposedly based on one that's been torn down and replaced a long time ago.

And there's this jungle gym in a kindergarten that's really really close that's shown as well.
The jungle gym, on the right in the screenshot here, was also shown in Kanon Episode 14 - 11m49s
Since I was already here I took a picture of the Kyoto Animation main office too. This time they had posters for A Silent Voice and Sound! Euphonium season two here.
And I went back to the building with the KyoAni Shop.
A Silent Voice and Sound! Euphonium posters in addition to a Violet Evergarden one at the KyoAni Shop. They're supposedly going to move the shop to a new location soon, so maybe I'll check out the new location later in 2017.
No location map since it's just next to Kowata Station and the Kyoto Animation main office.
This location was visited on 2016/10/21.
If you decide to visit this place yourself, do remember that the kindergarten still in use and you should NOT enter it.
Special thanks to the ones who went here before:
