Satomi Park is a peaceful spot to take a break. Enjoy a picnic lunch, wander around the grounds or just lie on the grass and shut your eyes for a while.
You'll be spoiled for sightseeing choice when spending time in Ichikawa. Satomi Park is an ideal place to begin here, but there are lots of other interesting sights to appreciate. Tokyo Skytree, Sensō-ji Temple, and Asakusa Shrine are close to the recreation and green space and will fill in your day nicely.
