A large aquarium that reproduces the natural sea and sparks a group swimming of 50,000 sardines boasting the largest number in Japan
Small fish that change into various shapes to protect themselves, a group of medium-sized fish aiming for it, and large fish such as sharks that reign at the top. There is a harsh natural sea of "eat and eat". In the sea, a school of fish that migrates according to the changing seasons receives the sunshine and shines beautifully.
LABO5 reproduces the "herd and shine" that survives robustly in the harsh natural sea.
