Joetsu City Aquarium Museum "Umigatari" is holding a seasonal event timed to coincide with the cherry blossom season. "Sakura Saku Haru no Umigatari 2026" runs from March 20, 2026 (Friday / public holiday) through April 19, 2026 (Sunday).
Under the theme of "Ibuki" (Breath of Life), the event features exhibits and activities designed to capture the vibrant energy of living creatures as a new season begins.
Hanasaka Diver: Fish Bloom into a Giant Sakura Flower
A diver dressed as the "Hanasaka Jisan" (Flower-Blooming Grandfather) from a beloved Japanese folktale makes an appearance inside the "Umigatari Main Tank." The diver feeds the fish with beautiful pink krill (okiami), drawing the fish to swarm and creating a spectacular effect — as though a giant cherry blossom flower is blooming inside the tank.
Schedule:
- Weekdays: 12:00 PM
- Weekends & public holidays: 12:00 PM and 2:15 PM
Location: Umigatari Tube
Japanese Tank Sakura ver.: A Springtime Display
A special "Japanese style" tank decorated with spring-inspired arrangements is on display as the "Japanese Tank Sakura ver.." Inside, goldfish drift gently through the water like falling cherry blossom petals, offering a quietly beautiful sense of spring's arrival.
Location: 3F Lobby
Displayed creature: Goldfish
