Iro Park (色 公園 Iro Kōen) is a place located in Nijiiro City.
It is a big park near Ayaka's neighbourhood. Chika's neighbourhood is also close to it, though it takes a little longer to walk there than if someone walks from Ayaka's neighbourhood. The entrance has a small set of stairs to go up, when you arrive you'll see there is a floor made of white tiles, a couple of benches and a fountain. You will see some stairs going down up ahead, and going down will lead you to the grassy area. The grassy area has plenty of trees, and there are a few more benches. There is also a flower bed. The sea is visible from the whole park.
- This park is where Chika normally spends her free time, if not in her garden.
