MOMIJI AQUARIUM by NAKED Ran Until November 8, with Two Evening Dolphin Shows a Day

At Maxell Aqua Park Shinagawa, the aquarium inside the Shinagawa Prince Hotel (Takanawa, Minato-ku, Tokyo), the autumn-leaf-themed seasonal event “MOMIJI AQUARIUM by NAKED” was on until Sunday, November 8. The event began on Saturday, September 12; it was organized by the aquarium and planned, directed and produced by NAKED, INC. An update of the event of the same name held in autumn 2025, it linked the exhibits throughout the aquarium with autumn-leaf motifs, starting with “Momiji no Mizuakari” (Water Lights of Autumn Leaves), which uses 22 projectors.

The final-weeks schedule: evening dolphin shows at 17:30 and 19:00

Opening hours are 10:00 to 20:00, with last entry at 19:00 (according to Yokohama Hakkeijima Inc.’s September 2 announcement). The night program “Gekka Koyo” (Moonlit Autumn Leaves) has been held twice a day since October 1, starting at 17:30 and 19:00. Each show lasts about 15 minutes and, without an MC, is composed of staging with water, light, video and sound. The official website describes it as dolphins swimming on a stage depicting autumn scenery.

The daytime program is “Autumn Dolphin Festa,” in which dolphins and trainers dance on an autumn festival theme, and the dolphins leap to Latin-style music. Each show also lasts about 15 minutes, with start times varying by period. The “Dolphin Performance Reserve Plan,” a limited-number set that secures seats for one daytime show together with an admission ticket, went on sale on the official website on Thursday, September 3.

The otter program switched to its second half, “Otter Festival,” on October 5. It takes place at 12:30 for about 10 minutes until November 8.

Staging by area and the creatures on display

At the entrance, in “Mai Momiji no Monogatari” (The Tale of Dancing Autumn Leaves), the video on the surrounding walls moves through three scenes in about five minutes, and red lanterns light up as the autumn scenery progresses from morning to night. Visitors are greeted by redfin anthias and flame angelfish.

“Momiji no Mizuakari,” in the “Patterns” area, is an immersive space using 22 projectors. The official website describes it as a garden-like exhibit where fish reminiscent of leaves and autumn foliage swim. Sliding-door paintings open about every three minutes, and parrot fire cichlids are displayed in the center. There is also a device that spreads ripples underfoot in step with visitors’ movements.

In the atrium, “Shusai no Minori” (Autumn-Colored Harvest) lines up creatures evoking seasonal autumn foods, such as flowerhorn cichlids and spotfin burrfish, in seven small tanks. In the jellyfish zone “Jellyfish Ramble,” moon jellyfish and others are shown amid lighting suggestive of autumn leaves and moonlit nights and the sounds of Japanese instruments.

“Akane Chaya” in the Coral Cafe Bar is a space with a Japanese feel created with autumn leaves and oil-paper umbrellas, where visitors can enjoy a limited autumn menu while looking at glowing coral and cylindrical tanks. The official website lists Fruit-Packed Sangria (800 yen, alcoholic), Cinnamon-Scented Apple Soda (750 yen), Sweet Purple Sweet Potato Latte (850 yen) and Crunchy Maple Nuts (800 yen); the menu is subject to change.
