Marine Day

What Is Marine Day?

Marine Day, known as Umi no Hi (海の日) in Japan, is a national public holiday dedicated to appreciating the ocean. It serves as an opportunity for the Japanese populace to express gratitude for the bounty of the sea and to reflect on the nation’s historical and cultural relationship with its surrounding waters. The observance highlights Japan’s identity as an island nation, intrinsically linked to the marine environment for sustenance, trade, and cultural development.

This holiday encourages a deeper understanding of the ocean’s importance, not only as a source of food and resources but also for its role in global ecosystems. People are encouraged to acknowledge the maritime industry and the ecological balance of the seas. Marine Day is one of the more recent additions to Japan’s list of national holidays.

History and Origins of Marine Day

The origins of Marine Day can be traced back to Emperor Meiji’s historic voyage in 1876. On 20th July of that year, Emperor Meiji returned to Yokohama Port after a significant inspection tour of the Tohoku region and Hokkaido, conducted aboard the Meiji-Maru, an iron steamship. This voyage was pivotal for the development of modern Japan, symbolising the nation’s engagement with maritime travel and its future.

Initially, 20th July was designated as Marine Memorial Day (Umi no Kinenbi) in 1941, not as a public holiday but as a day of observance by the Ministry of Communications. Its purpose was to commemorate the Emperor’s voyage and promote maritime awareness. In 1996, the day was formally established as a national public holiday, renamed Marine Day (Umi no Hi). This change elevated its status and allowed for widespread public participation. In 2003, as part of Japan’s “Happy Monday System,” Marine Day was moved to the third Monday of July to create a three-day weekend.

How Marine Day Is Celebrated

Marine Day is celebrated throughout Japan with various activities that underscore the importance of the ocean. Many people take advantage of the long weekend to visit beaches, engage in swimming, surfing, or other water sports. Coastal areas often host special events, including festivals, educational programmes about marine life, and environmental clean-up initiatives.

Aquariums across the country typically experience increased visitor numbers, often holding special exhibitions or shows related to marine conservation. Some cities organise fireworks displays along the waterfront, adding a festive atmosphere to the observance. Families and individuals use this day to connect with nature, appreciate the ocean’s beauty, and reflect on its significance to the nation’s heritage and future.

When Is Marine Day?

Marine Day is observed annually on the third Monday of July in Japan. This fixed-day-of-the-week system was introduced in 2003 as part of Japan’s “Happy Monday System,” which shifted several national holidays to Mondays to create more three-day weekends. Prior to this change, Marine Day was celebrated on 20th July, its original commemorative date.

As a result of being a variable Monday holiday, the exact date of Marine Day changes each year but always falls within the third full week of July. This allows for consistent planning of long weekends, which benefit tourism and leisure activities across the country. The holiday is based on the Gregorian calendar.
