2026 Rainbow Plaza Water Play Area Full-Day Course

This course packs a full day of play into one neighborhood, starring the Rainbow Plaza Water Play Area at Kibi Plaza in Kibichuo Town, Kaga District (加賀郡吉備中央町). Besides the water play area, the outdoor plaza at Kibi Plaza has a long roller coaster and a large play structure, and indoors there is also a children's space called Kids Park. You can move back and forth between outdoors and indoors to match the weather and everyone's energy, so the plan rarely falls apart even with small children, which is what makes this spot so dependable. The adjoining Kibi Chuo Park (吉備中央公園) is free to use as well. Admission costs nothing, but the water play area runs from 10:00 to 15:00; in a typical year it operates on weekends and holidays from May to September, and daily during the summer vacation period. The exact opening period for 2026 has not been announced, so check the Kibichuo Town information before you set out. In the morning, walk the quiet highland precincts of Yoshikawa Hachimangu Shrine (吉川八幡宮), then spend unhurried time at Kibi Chuo Park (吉備中央公園). Have lunch at Kibi Plaza, and in the afternoon head for the water play area at Rainbow Plaza. It is a day of play in the coolness that only the high-elevation Kibi Highlands (吉備高原) can offer.
