Mountain Day Description
Mountain Day (山の日, Yama no Hi) on August 11th is Japan's newest national holiday, established in 2016 as an opportunity 'to get familiar with mountains and appreciate their blessings.' With approximately 73% of Japan's land mass being mountainous, the holiday recognizes the central role mountains play in Japanese geography, culture, and spirituality — from the sacred peaks of the Three Holy Mountains (Mount Fuji, Mount Tate, Mount Haku) to the mountain ascetic traditions of Shugendo. It falls during the Obon holiday season (mid-August), when many Japanese return to their hometowns to honor ancestors, making it part of one of the busiest travel periods of the year. Mountain trails, hiking routes, and national parks see peak visitor numbers. Climbing Mount Fuji is particularly popular during this period — the official climbing season runs from early July to early September. Alpine resorts in the Japanese Alps offer summer hiking and flower viewing. Government offices and schools close. In 2026, August 11th falls on a Tuesday, making it part of a short break potentially extended with Monday off. Public transport to mountain areas is crowded. Cable cars, ropeways, and mountain hut accommodations should be booked well in advance.
