2026 Kodomo no Kuni (こどもの国) Seseragi: A Full-Day Course

This full-day course centers on Seseragi (せせらぎ), a water-play area at the vast Kodomo no Kuni (こどもの国) facility in Aoba Ward, Yokohama City. In 2026 it's open from mid-March to mid-October, and can be used just with regular park admission while Kodomo no Kuni is open. Hours are 9:30 a.m. to 4:30 p.m. (until 5:00 p.m. in July and August). In the morning, first interact with ponies and other animals in the ranch area within Kodomo no Kuni (こどもの国), then take a leisurely bike ride around the park on the cycling course. After lunch, head to Seseragi (せせらぎ) and enjoy water play to your heart's content in the shallow stream until evening. The spacious grounds require little travel between spots, making it easy to spend a full, relaxed day as if in your own neighborhood. This outing is perfect for families, letting you enjoy animal encounters, active play equipment, and water play all in one visit.
