Since 2016, Hokkaido University has been hosting the Treasures of the Sea Academic Contest, the heart of the Marine Learning Event. Presentational works from junior high and high school students all over Japan are put on display; these are based on their personal “Treasures of the Sea” in the two categories of culture and science. Winning works from the first round of selections in 4 different areas nationwide are invited to Hakodate, where the final competition will be held. Through their experience of the various events and the contest, we hope to develop individuals who will shoulder the future of the oceans.
