At the Sunshine Aquarium in Ikebukuro, Tokyo, a night-only collaboration event "Sunshine Aquarium ×GENERATIONS ~6IX SUMMER FEELINGS~" with the six-member dance and vocal group "GENERATIONS" is being held from June 20 (Friday) ~ August 31 (Sunday), 2025. FUN! JAPAN editor will report on the highlights and how to enjoy it.
It's going to be the best summer ever. The collaboration between "Sunshine Aquarium ×GENERATIONS" has been realized!
In 2025, GENERATIONS will enter its 13th year of formation! The project "PRODUCE 6IX COLORS" was developed to distribute and release songs produced by each member for six consecutive months, and the arena tour "6IX SENSE" was held in the fall, and a collaboration between GENERATIONS and the Sunshine Aquarium, which is riding the updraft right now, was realized.
The members of GENERATIONS produced a variety of content in the Sunshine Aquarium for this event to decorate summer nights. Along with many songs, the creatures of the Sunshine Aquarium and the members of GENERATIONS will take you to the best summer.
COMMENTS FROM GENERATIONS HAVE ALSO ARRIVED:
We are very pleased that GENERATIONS will be collaborating with Sunshine Aquarium this time. An aquarium is a space filled with the "excitement" and "wonder" that I felt as a child, and it is also a place that brings new "encounters" and "emotions" as an adult. There is a lot of overlap with the theme of this year's tour, "6IX SENSE", and every time you come into contact with the mystery of living things and the beauty of nature, you will feel "new sensations and emotions". I would be happy if I could share that feeling with everyone who comes to the exhibition through this collaboration. In the exhibitions and experiences, there are elements that link our music and the individuality of each member, and "6IX COLORS" ── You can feel the colors and individuality of each of the six members. We hope that you will spend time with your family, friends, and loved ones to brighten your heart.
A space created with the music of GENERATIONS and the colors of each of the six members

During the event, the experience is divided into seven periods, songs selected by each of the six members will be played as background music in the hall during each period, and the outdoor area "Marine Garden" will be illuminated in the color of each member. In the final week, a special setlist "6IX SUMMER FEELINGS" will be played, allowing guests to feel all six emotions! The entire aquarium will be dyed in the color of GENERATIONS.
In addition, an original panel introducing GENERATIONS members' impressions of the aquarium and recommended sea creatures will be displayed. At the start of the background music, pre-recorded announcements by the members will also be broadcast. A campaign to find "GENEKO" that hide in various places in the building, will also take place.

From here, here are some of the highlights of the event and how to enjoy it, from the FUN! JAPAN editor of actually covered at the aquarium.
The "Penguin in the Sky" tank will be dyed in "PRODUCE 6IX COLORS"!


In the "Penguin in the Sky" tank in the outdoor area "Marine Garden", songs produced by each member to be released in "PRODUCE 6IX COLORS" planned during each period are played repeatedly. There will also be decorations with artist photos of the members for each period and panels with music app-style designs of the songs.
The background music that was playing at the time of the interview was "True or Doubt" produced by Yuta Nakatsuka. While listening to the music, you can enjoy the sight of the penguins spreading their wings in the tank above you and moving through the water. The penguins are swimming smoothly in the water and are very cute! They were full of energy and lively, which matched the up-tempo songs perfectly!
In other areas, GENERATIONS' music is played as background music to match the "Summer emotion" of each period, and in the outdoor area "Marine Garden", the illumination colors are also produced with each color in mind.
* The exhibition of Cape penguins in the "Penguins in the Sky" tank is until 19:00. (During the opening hours until 20:00, you can enjoy the music and the illumination space to match it, even if there is no penguin exhibition.) )
Sensation of sea moon sky "Jellyfish Panorama" Fantastic illumination production of the aquarium


In the "Jellyfish Panorama" tank — one of the widest jellyfish tanks in Japan, located in the jellyfish area "Umi Moon Sora Kan" on the 1st floor of the main building, special lighting effects are performed in sync with GENERATIONS songs selected by the members. You can sit and enjoy the view. During our visit, the featured songs weren’t up-tempo but rather three ballads, with the color of the lighting changing to match the song. The gentle floating and relaxed movement of the jellyfish were more pronounced, creating a romantic and fantastic space!
In addition, during the exhibition, the music will be different between the first half and the second half. Don't miss the medley and jellyfish that can only be heard here! I'm looking forward to seeing what kind of production will be next and whether up-tempo songs will also appear!
*Period: First half: June 20 (Fri) ~ July 18 (Fri), Second half: July 19 (Sat) ~ August 31 (Sun)
* It will be held every hour at 00, 20 minutes, and 40 minutes after the event start time.
* When the time comes, the music will play and a special lighting production will begin.
Lots of photo spots! TOGETHER WITH GENERATIONS!

In the outdoor area "Marine Garden", there is a panel exhibition of all members, and you can stand next to your favorite member, pose and enjoy taking pictures.


There are also panels with impressions and explanations of the creatures in the aquarium set up in various parts of the museum, announcements recorded by members that are broadcast in the museum, and greeting videos from all members. It's like going around the aquarium with the members!

It is also interesting to look for the new official GENERATIONS character "GENEKO" to hide in the hall. "Oh, it's hidden in a place that's easier to understand than I thought ~". (laughs)

In addition, the limited-time "Aquarium Cocoa GENERATIONS ver.", which will be sold at the "Tully's Coffee Sunshine Aquarium Store" in the building, is also perfect for your break time! There are a total of 7 types of drinks printed with SD character designs drawn by GENERATIONS members for this event and the new official character Jeneko. The design is random, so I'm excited to see if I can get my own favourate member! This time it was design of Ryota Katayose! The penguins next door are also cute!

Finally, you can purchase collaboration limited goods at the "Shop Aqua Pocket" on the 2nd floor of the main building.
