2026 Mizu no Rakuen Monpuru Water Paradise (水の楽園 モンプル) Full-Day Course

A one-day course starring Mizu no Rakuen Monpuru (水の楽園 モンプル), the outdoor leisure pool inside Japan Monkey Park (日本モンキーパーク) in Inuyama City, Aichi Prefecture (愛知県犬山市), open from Saturday 4 July to Wednesday 23 September 2026, a public holiday. In the morning, first enjoy the views from the keep of Inuyama Castle (犬山城), a National Treasure rising beside the Kiso River (木曽川), then walk at leisure along Honmachi Street (本町通り) in the castle town and sample its street food. Once you are full, it is on to Mizu no Rakuen Monpuru. Small children can play safely in the shallow pool, while several water slides keep adults and children alike absorbed. Changing rooms, hot showers, spin dryers and even a first-aid room are provided, which is reassuring for families visiting for the first time. It opens at weekends in July, daily in August, and only at weekends and on public holidays in September, so choosing your date lets you enjoy it at an easy pace. A summer outing that captures Inuyama City in Aichi Prefecture, with both a history walk and water play in a single day.
