One of the most important locations of the Onegai Sites Tour! Some scenes of the Opening of Onegai Twins are at this location. Very easy to find, only 2 minutes of walking from the youth hostel I stayed at, which is next to the popular Onegai accomodation.

Most of the pictures at this location are taken on a rainy day, that's why there's nobody around. For the people who don't know Onegai Twins, I added a scenery picture taken at that location. Standing at the playground looking at the lake, weather was nice when I took that picture.

While searching for a Youtube link of the Onegai Twins Opening, I also found a link for the first part of episode 1. Notice the Club Sega, that is at Akihabara station (Tokyo) Electric Town Exit, standing somewhat under the JR-railway. The pictures I have are standing next to the JR-railway, should have moved a bit to the left >_>
Just to prevent confusion, the last two pictures were taken in Akihabara, Tokyo.

Also notice the three benches and the tree behind the swings (5th picture), can be seen in the opening. I didn't take a picture of that -_-;
