From Friday, November 13 to Friday, December 25, 2026, Maxell Aqua Park Shinagawa in Takanawa, Minato-ku, Tokyo will host "LittleTwinStars AQUARIUM," a winter-only event in collaboration with Sanrio Co., Ltd.'s Little Twin Stars (Kiki & Lala). The event is planned, directed, and produced by NAKED INC.
A Christmas-Only Aquarium Experience with Little Twin Stars, Woven from Light and Story
This experiential art event, held in collaboration with Little Twin Stars, takes place at Maxell Aqua Park Shinagawa. Inside the aquarium, visitors will find a photogenic entrance where stars and the sea connect, and an area depicting a "night-sky sea" where touching a constellation makes sea creatures begin to swim, creating romantic, heart-fluttering scenery.
The journey begins in "Twinkle Cloud Room," where Little Twin Stars (Kiki & Lala) welcome guests. Together with Little Twin Stars, who have come to visit Aqua Park Shinagawa, visitors begin a story of mysterious encounters with sea creatures.
Further inside is the immersive area "Sparkling Sky Ocean," where touching the sea creatures floating as constellations makes them wrap themselves in light and start swimming. From there, the story gradually leads into a world where colorful creatures live, as if diving little by little into the sea.
The finale is a dolphin performance that tells a different story by day and by night. The daytime show portrays the "sparkling encounter" between Little Twin Stars and the dolphins. The nighttime show is a special program unique to the Little Twin Stars collaboration, themed around a Christmas party in a "sea where stars fall."
With stars, the sea, light, and sea creatures connected as one, "LittleTwinStars AQUARIUM" lets visitors travel through a story. Surrounded by the gentle, dream-filled world of Little Twin Stars, visitors can spend a special time journeying through the story themselves in a space woven from stars, sea, light, and living creatures.

About Little Twin Stars
Little Twin Stars are twin star siblings born on the Caring Star (思いやり星) in the Dream Nebula (ゆめ星雲). They came from a distant star country to become brilliantly shining stars. The older sister, Lala, is timid and a little bit of a crybaby, while the younger brother, Kiki, is full of curiosity, a little hasty, and fond of playing pranks.
