Kyochika's take

A Christmas-only aquarium dyed in Kiki and Lala's soft blue and pink

Highlights are the white tree at the entrance and the night-sky tank where touching constellations sets sea creatures swimming, plus a special dolphin show

Last entry is 19:00 and it is close to Shinagawa Station, so it could suit an after-work date

About this event

Kiki and Lala, the twin Sanrio characters created for Christmas gifts in 1975, celebrate the season alongside marine life. The collaboration marks the Little Twin Stars' 50th anniversary in 2025 and is themed Twinkle Christmas. At the entrance, Twinkle Cloud Room features a pink house and a white Christmas tree, with pale-blue green chromis and bright-pink purple queen anthias swimming in nearby tanks. Four aquarium areas feature digital effects that bring sea creatures to life when visitors touch constellations, displays inspired by Christmas ornaments, and jellyfish illuminated in blue and pink. A special version of the dolphin performance brings together the twins' world of stars and the real underwater world.

Summarized from the official page and press materials.

Why were Kiki and Lala created for Christmas?

Little Twin Stars, better known as Kiki and Lala, debuted in 1975. Sanrio developed them for Christmas gifts, taking inspiration from stars shining in the cold winter sky. Early merchandise included small pouches shaped like Christmas stockings and mittens. My Melody also made her debut that same year.

Surprisingly, the twins did not originally have individual names. Little Twin Stars was their first collective name, while Kiki and Lala were later chosen through a reader competition in Sanrio's monthly Ichigo Shimbun publication. Other suggestions included Larry and Lily. The chosen names expressed the hope that the twins would work together and shine like stars.

In their fictional story, the siblings were born on the Star of Compassion in the Dream Nebula. Lala, the older sister, is timid and sometimes tearful, while her younger brother Kiki is curious and mischievous. They travel to Earth to learn how to become shining grown-up stars. Kiki receives a flying star from his mother, while Lala receives a magical star wand from her father. Their birthday is Christmas Eve, December 24.

Their familiar blue and pink hair was not part of the original design. Kiki initially had brown hair and Lala had yellow hair. Their appearance evolved over the decades, reaching their 50th anniversary in 2025. As characters originally inspired by the Christmas night sky, their aquarium collaboration has a special connection to their beginnings. That is why the starry sky of Twinkle Cloud Room and its blue and pink fish are worth a closer look.
