Every year on the third Monday of July, Japan celebrates Marine Day (Umi no Hi)—a national holiday dedicated to honoring the ocean, appreciating its bounty, and recognizing its vital role in the country’s culture and economy. Since Japan is an island nation deeply connected to the sea, this holiday holds special significance, reminding people of the ocean’s beauty and the responsibility we all share to protect it.
Though Marine Day is uniquely Japanese, its spirit of respect and celebration for the ocean resonates worldwide. Whether you live by the coast, near a lake, or simply love the water, there are countless ways to embrace the essence of Marine Day and cultivate your own connection to the sea—and your wellbeing.
The History and Cultural Significance of Marine Day
Marine Day was first established in 1941 as “Ocean Day” to mark the return of the Meiji Emperor from a voyage on the Pacific Ocean. After being abolished during World War II, it was reintroduced in 1996 as Marine Day to encourage appreciation for the ocean’s blessings and promote maritime development.
For Japan, the ocean is more than just a natural resource—it’s a cultural cornerstone. The sea has historically supported fishing communities, enabled trade and exploration, and inspired art and literature. Marine Day honors this legacy by fostering awareness of the ocean’s importance to daily life and future sustainability.

The Blue Mind Theory: How Water Boosts Mental Health
Marine Day is not just about fun and festivities; it’s also about wellbeing. The Blue Mind theory, coined by marine biologist Wallace J. Nichols, explains how being near, in, on, or under water positively impacts mental health.
Nichols’ research shows water exposure:
-
Reduces stress and anxiety
-
Enhances creativity and calm
-
Improves focus and mood
-
Supports overall emotional balance
Our brains respond to water’s sensory stimuli—sounds, sights, and sensations—by activating relaxation pathways, helping to quiet busy minds and reset emotions.
Embracing Marine Day by spending time near water can be a powerful mental health boost, especially in today’s hectic world.
