Definitely one of the Onegai Sites Tour locations, inside the waiting room there is a table with Onegai Twins items and comment books. Most important item there is a picture that appeared in the anime, two children in a pool in front of the Maiku House. I'm still amazed that nobody steals that picture! It's just a waiting room where someone put some items, no cameras, security or whatever! It's like leaving your wallet on the streets and 5 years later it's still right there where you left it!

Anyway, you can consider this as an otaku station. According to another location hunt site: "Haruko & gang tricked Miina & Maiku to kiss here."

As for what I know of this station, 4 minutes walk from H-shop and last possible train towards Shinjuku (Tokyo) is at 4:53 PM. This is also the best of the tree stations at Kizaki Lake, very comfortable waiting room.
I spent very little time at this station. Every time I arrived there, I only had like 3 minutes to write something in the comment book. Took a few quick pictures of some comments, some people really took some time to make something. Maybe if I am there next time and I got some time, I might draw something...
