Huis Ten Bosch, the Nagasaki Prefecture theme park resort known for its "a longed-for other world" branding, is introducing a new promotion called 「夏だってワクワク割！」 starting Friday, August 7: whenever the forecast high temperature for northern Nagasaki Prefecture (Sasebo City), where the park is located, reaches 35°C or higher — an official "extremely hot day" — admission tickets and Express Passes will be sold at 10% off.
With intense heat continuing nationwide this summer, the park is running the promotion so visitors can enjoy the pools, fireworks, and attractions more comfortably and at a better price.
The discount covers not just admission tickets but also the Express Pass, which allows priority entry to attractions, making it a good option for anyone hoping to tour the park efficiently while avoiding the heat.
Huis Ten Bosch offers entertainment from morning to night, including its seasonal resort pools, indoor attractions that make up around 70% of the park's facilities, and nightly fireworks and shows that light up the sky. The park has also stepped up its heatstroke prevention measures, with a large indoor rest space and all-day select drinks, plus special discounted stays at its official hotels this summer.
