Japan Holiday Calendars
Mountain Day, observed on August 11, encourages people to appreciate Japan's many mountains and the blessings of nature. It is a time to explore the outdoors, reflect on the environment, and enjoy scenic landscapes.
Mountain Day: A Public Holiday?
Mountain Day (Yama no Hi) is a national public holiday in Japan, with schools, offices, and most businesses closed to encourage appreciation for the country's natural mountain landscapes.

Mountain Day
Mountain Day, or Yama no Hi, is one of Japan's newest public holidays, officially established in 2016. The idea for the holiday came from various outdoor and environmental groups that wanted a special day to celebrate Japan's mountainous geography and encourage people to spend time in nature. With over 70% of Japan's land covered by mountains, they have long played an important role in the country's culture, religion, and daily life.
August 11 was chosen for Mountain Day because the kanji for eight (八) resembles the shape of a mountain, while eleven (十一) evokes the image of two trees standing side by side, symbolizing nature and the outdoors. Although Mountain Day is not tied to a specific historical event, it was created to give people a chance to reflect on the importance of mountains in their lives. The holiday also adds a break during the hot summer months and helps promote environmental awareness, health, and outdoor activities across the country.

The holiday falls in the middle of summer, making it ideal for outdoor adventures and rest.

In places with famous mountains or scenic views, community festivals and educational programs may be held to promote environmental conservation and tourism. Schools and environmental groups also use the day to raise awareness about climate change and the importance of protecting mountain ecosystems.
The importance of Mountain Day lies in its message of reconnecting with nature.
