Honoring the oceans. Marine Day in Japan
In Japan, the third Monday in July is Marine Day (also known as Ocean Day), a day to show appreciation for the seas and oceans. Other nationalities have similar observances, but as inhabitants of an island nation, people in Japan can claim a particularly strong connection to the waters that surround them. The modern holiday also serves as an official start of summer in Japan, and many folks hit the beach to celebrate the end of tsuyu, the rainy season. The holiday started as Marine Memorial Day in 1941 to mark the anniversary of the return of the Meji Emperor from a voyage in 1876, but it wasn't observed as a national holiday until 1996. Some also mark Marine Day with environmentally friendly activities. In Okinawa, people throw EM (effective microorganism) mudballs into the sea—these contain bacteria and yeast targeted at eliminating sludge and slime. Other areas host beach cleanups and aquariums host special Marine Day events.
