The Night Pool at Lagunasia theme park in Gamagori, Aichi is set to open for summer 2026 on Saturday, July 11. This year's edition gains a new highlight: an illumination dome called "Marine Fantasia," installed on the island in the middle of the flowing pool "Uroboros River," making the nighttime atmosphere even more enchanting. Floating in the pool while watching the illumination display is one of the signature experiences unique to the Lagunasia Night Pool.
The popular adult-only event "Laguna Pool Party 2026" — limited to guests aged 16 and above — also returns for another run, wrapping guests in DJ music and a massive foam party that has drawn crowds year after year. Adding to the summer excitement, the limited-run fireworks spectacular "FLAME" and launch fireworks show "Splash GIGAMAX" will let guests enjoy spectacular fireworks and show effects right from the pool. Entertainment shows including dance performances and illuminated fountain displays round out the experience.
