In addition to the Air locations in Mio in Mihama, I also checked out some additional Air locations in more central parts of Mihama in Wakayama.

This is in Yoshihara in Mihama. The building on the left side has been torn down, but the right side still matches.

They made a new and longer OP for the Blu-Ray release of Air, in which this place was shown.

Next I crossed into the nearby Gobō city. This place is right behind Nishi-Gobō Station, which is also the closest train station to all these locations.

Crossing back, this location can be found in the Hamanose parts of Mihama. It's become more overgrown, but the buildings in the background still matches.

I've marked a path going through all the locations and ending up here in the map below.
I took the train from Nishi-Gobō Station back to Gobō Station. This is supposedly the second shortest railway line in Japan and it's operated by Kishū Railway.
They had a guestbook in Nishi-Gobō Station mainly for rail fans.
But there were also some signatures by Air fans.
I signed it too of course.
This location was visited on 2016/10/20.
Special thanks to the ones who went here before:
