Kasaoka Sun Square stretches for about 3.5 km along the dike of the Kasaoka Bay reclamation area, and is equipped with a variety of facilities, including large playground equipment, grand golf, promenades, cycling roads, roller skating rinks, BMX courses, and dog runs.

The park's great appeal is its vastness and versatility. At the grassy area in the center of the square, you can enjoy a variety of leisure activities, such as ball games and badminton. You can spread out your lunch and have a picnic, or just lie down and relax.

This park is recommended for families with children.

[Hidden gem]
A few minutes by car, there is a popular gelato shop called Gelateria Luho, run by a dairy farmer, so it's a good place to stop by to cool off on a hot summer day.

Also, nearby is the roadside station Kasaoka Bay Farm, where you can purchase fresh local vegetables and specialty products.

[Useful points of concern]
Because the park is long from north to south, there are seven parking lots scattered around. It is best to choose a parking lot according to your purpose. There are two large playground equipment locations, one on the wide lawn on the north side and one at the south end.
There are areas with a lot of shade and other areas with not much, so it's a good idea to choose a spot for a picnic depending on the season and weather.
