About Marine Day
Marine Day, Umi no Hi, is a day to give thanks for the blessings of the ocean and to hope for the prosperity of Japan as a maritime nation. It became a national holiday in 1996, first held on 20 July, the date in 1876 when Emperor Meiji returned to Yokohama aboard the lighthouse tender Meiji Maru after a tour of northern Japan. It has been held on the third Monday of July since 2003.
Traditions
The holiday falls around the start of the school summer break and the beach season, and many people go to the seaside. Ports and coastal towns hold events, and some ships are opened to the public.
