Marine Day in Japan – July 21, 2025
Every year, Japan sets aside a special day to celebrate the vast and mysterious oceans that surround its beautiful islands. Marine Day, or “Umi no Hi,” is observed on the third Monday of July, and in 2025, it falls on July 21. This national holiday is a time when Japanese people reflect on their rich maritime history, express gratitude for the ocean’s bounties, and acknowledge the critical role the seas play in their lives.
The History Behind Marine Day
Marine Day was first celebrated in 1941 as “Marine Memorial Day” to commemorate the Meiji Emperor’s return to Yokohama on a steamship in 1876. It wasn’t until 1996 that it became a national holiday, aimed at increasing public awareness about Japan’s dependence on the oceans for its prosperity and well-being. Given Japan’s status as an island nation, the sea has always been a vital part of its culture, economy, and way of life.
Why is Marine Day Significant?
The ocean is more than just a scenic backdrop for Japan—it’s a lifeline. From fishing and trade to tourism and energy, the seas have supported the nation in countless ways. Marine Day is a moment to appreciate these contributions, reflect on the importance of marine conservation, and consider how to sustainably manage ocean resources for future generations. It’s also a day to enjoy the beauty and recreational opportunities that the sea provides.
How Do People Celebrate Marine Day?
Marine Day is marked by a variety of events and activities across Japan. Coastal areas often host beach clean-ups, maritime parades, and fireworks displays. Families take this opportunity to visit aquariums, enjoy seaside picnics, or engage in water sports like surfing and paddleboarding. Educational programs and exhibitions about marine life and conservation efforts are also popular during this time.
In Tokyo, for example, you might find special events at Odaiba’s waterfront area, including live performances, seafood festivals, and interactive workshops for kids. In more rural coastal towns, traditional ceremonies to honor the sea are still practiced, blending modern appreciation with ancient customs.
