2026 Shirakobaato Suijo Park (Arnet Home Smile Park Shirakobaato) – Full Day Experience Course

A full-day experience course centered around Shirakobaato Suijo Park (Arnet Home Smile Park Shirakobaato) in Koshigaya City, which operates from July 4 (Saturday) to September 6 (Sunday), 2026. In the morning, walk along the lush tree-lined approach at Kuizu Shrine (Koshigaya's patron shrine), where you can pray for a safe journey. At lunchtime, visit the prefecture's leading large-scale commercial facility "Aeon Laketown" and enjoy a relaxed meal, selecting your favorite items from the food court. After filling your stomachs, head to Shirakobaato Suijo Park. Until 5 PM, enjoy plenty of water activities—floating leisurely on an inflatable ring in the flowing water pool, sliding down water slides with excitement, playing in the sand at Shirahama Beach, and more. Changing rooms, showers, and shops are complete, so you can travel light and pack almost nothing. Operating days are only 7/4–5, 7/11–12, 7/18–8/31, and 9/5–6, so we recommend confirming the schedule before your visit. This is the perfect one-day course for making summer memories with the whole family.
