About Sea Day

Sea Day, or Umi no Hi, is a national holiday in Japan dedicated to expressing gratitude for the ocean's bounty and the prosperity it brings to the island nation. Originally established to commemorate the Emperor Meiji's return from a sea voyage, it now encourages environmental awareness and beach activities. Citizens observe the day by visiting coastal areas and participating in maritime festivals.
