This stage is set on an island called Shikoku. There was once a municipal aquarium in a small town on this island. It was built 87 years ago, and it was the very first aquarium in Shikoku. After that municipal aquarium closed, the townspeople wished to revive it once more and that’s how the Naga High Aquarium was born. It’s an aquarium inside a school. Ehime Prefecture Nagahama High School. They have the nation’s only Aquarium club, and there are 2,000 sea creatures of 150 kinds inside the school building. The club members feed the fish every day, cleans the tanks, and give their all to care for them. Those sea creatures can be seen at the public viewing every third Saturday of the month, and many people visit the school on that day. A popular event during the public viewing is “Tommy’s Yellowtail Show”. High school students became yellowtail trainers, and they trained yellowtails to create what may be the world’s first yellowtail show. The show puts a smile on everyone’s faces. It creates a moment of happiness. We began recording footage at Naga High Aquarium ever since the public viewing started in 1999. Among them is a segment covering six years of the yellowtail show, starting when the founder “Tommy” first entered the school. In 2018, western Japan suffered from a disaster caused by torrential rainfall. The school closed, and many fish died. In addition to that, Nagahama High School is not a preparatory school, and it’s not very easy to access, so they have to deal with declining student admissions. The school may have to close for good if there are not enough new students coming in. The club members shoulder the dreams of the townspeople and older students who left the club in their care, as they overcome crises and work hard every day. Together with all the sea creatures.
