Mountain Day is one of Japan’s newest public holidays. It is easy to see why the country chose to honor its mountains, as around 70% of Japan is mountainous. One of the most iconic peaks is Mount Fuji, which rises 3,776 meters and is recognized around the world as a symbol of Japan.
History of Mountain Day
Mountain Day was officially established in 2014 and first celebrated in 2016. The holiday was introduced through the efforts of mountain enthusiasts, conservation advocates, legislator Seishiro Eto, and supporters such as the Japanese Alpine Club. They argued that if Japan had a public holiday dedicated to the sea, it should also recognize the importance of its mountains.
Their efforts were successful, and August 11 was chosen as the official date. Since then, Mountain Day has become a national occasion for appreciating Japan’s mountain landscapes and the benefits they provide.
