We will create a "thrilling" experience full of playfulness by combining the everyday enjoyment of "snacks" with the extraordinary experience of a theme park. Why not spend a special, memorable time this summer with "Lagunasia" x "Baby Star" & "Butamen"?

This Summer Vacation, Experience the "Thrilling" Playfulness of "Baby Star" & "Butamen" at "Lagunasia"!

This collaboration event with "Baby Star" and "Butamen" at the theme park "Lagunasia" was realized from the desire of both companies to deliver "excitement."

During the collaboration period, a water play area decorated with Baby Star's character "Hoshio-kun" and "Butamen-kun" from Butamen will appear in Lagunasia's pool area. This is a water play area with a water depth of approximately 30 cm where small children can play with peace of mind, creating a "thrilling" space full of playfulness.

In addition, collaboration food that can be enjoyed by everyone from small children to adults will be offered, such as the "Baby Star Kids Box (1,500 yen)" and "Baby Star Churros (800 yen)" using "Baby Star Ramen."

Furthermore, in commemoration of "Smile Day" on August 8th, a special one-day event will be held on August 8, 2026 (Sat.) to bring smiles to our guests.
