Mountain Day in Japan: Honoring Nature and Celebrating the Peaks
Contents
A day to honor mountains. A day to breathe in the wild beauty of Japan.
Every year on August 11, Japan celebrates Mountain Day—a unique national holiday dedicated to appreciating the mountains that shape the nation’s land, culture, and spirit.
From the sacred slopes of Mount Fuji to the gentle trails near Tokyo, mountains have long been more than just scenery—they are sources of inspiration, worship, and adventure.
In this article, we’ll explore the origins and meaning of Mountain Day, the cultural role of mountains in Japan, and the many ways people celebrate—from traditional festivals and mountain worship to hiking trails and scenic spots worth visiting.
Whether you’re a seasoned hiker or simply someone who loves a stunning view, Mountain Day invites everyone to step outside, reconnect with nature, and discover why mountains hold such a special place in the heart of Japan.
What Is Mountain Day?
Mountain Day (Yama no Hi, 山の日) is celebrated every year on August 11.
It was established with a simple yet meaningful purpose: “to provide opportunities to get familiar with mountains and to appreciate their blessings.”
Officially recognized as a public holiday in 2016, Mountain Day is one of Japan’s newest additions to the national calendar. While many countries celebrate nature in various forms—such as Earth Day or Arbor Day—having a dedicated day to honor mountains is rare, making it a uniquely Japanese holiday.
Why August 11?
The date was originally considered to be August 12, placed just before the Obon summer holidays so people could easily take extended time off.
However, August 12 is also the date of the tragic Japan Airlines Flight 123 crash in 1985—the deadliest single-aircraft accident in history—whose crash site, Mount Osutaka Ridge in Gunma Prefecture, is itself a mountain. Out of respect for the victims and sensitivity to the symbolism, lawmakers and local officials strongly opposed making that day a national celebration.
As a result, the date was moved to August 11.
Although there is no officially confirmed symbolic origin, some media and local versions of Mountain Day have suggested that the kanji for “eight” (八) resembles a mountain’s shape, while “11” can evoke the image of two trees standing side by side. These interpretations are after-the-fact explanations, but they have helped make the date more memorable.
The Cultural Significance of Mountains in Japan
Mountains are an inseparable part of Japan’s identity—both physically and spiritually.
Nearly 75% of the country’s land is mountainous, shaping everything from settlement patterns to transportation routes, agriculture, and local culture.
Mountains as Symbols of Faith and Inspiration
Throughout history, certain peaks have become iconic symbols in religion, mythology, and art. Mount Fuji, with its graceful cone, is not only Japan’s highest mountain but also a sacred site and a UNESCO World Heritage cultural property. Mount Tateyama, in Toyama Prefecture, has long been revered as one of Japan’s “Three Holy Mountains,” alongside Fuji and Hakusan. Such peaks have inspired countless works of poetry, painting, and literature.
Mountain Worship and Sacred Practices
Japan has a rich tradition of mountain worship (sangaku shinkō, 山岳信仰), where mountains are viewed as dwelling places of deities or spirits. This belief gave rise to Shugendō, a syncretic religion blending Shinto, Buddhism, and Taoist practices. Practitioners known as yamabushi train in the mountains, seeking spiritual power and enlightenment.
Many shrines and temples—such as Fujisan Hongū Sengen Taisha in Shizuoka Prefecture or Togakushi Shrine in Nagano Prefecture—are located at the foot or summit of mountains. Ōmiwa Shrine is especially notable because it has no main hall; instead, the mountain Mount Miwa is worshipped directly as the god.
Influence on Seasons, Agriculture, and Daily Life
Mountains are not just spiritual symbols—they are life-giving. They influence Japan’s climate and seasons, creating microclimates that support diverse flora and fauna. Mountain snowmelt feeds rivers that irrigate rice paddies, and forests provide timber, wild plants, and pure spring water.
This pure, mineral-rich water—filtered naturally through mountain soil and rock—is the secret behind many of Japan’s finest products. It nurtures the growth of high-quality rice, the foundation of Japanese cuisine, and serves as a key ingredient in brewing sake of exceptional flavor and aroma. From delicate tofu to regional noodle dishes, countless culinary treasures owe their taste to the clean, abundant waters flowing from Japan’s mountains.
For centuries, mountain landscapes have marked seasonal change—blazing autumn foliage, snow-capped winter peaks, and lush green slopes in summer—enriching festivals, local cuisine, and everyday life.
How Japanese People Celebrate Mountain Day
While Mountain Day carries a deep cultural meaning, it is also a lively occasion for outdoor enjoyment and relaxation. Falling in mid-August, it coincides with Japan’s summer holiday season, making it a perfect time for travel, family outings, and nature-based activities.
Outdoor Adventures
Many people take advantage of the holiday to explore Japan’s diverse mountain landscapes. Popular activities include:
- Hiking and trekking through national parks and scenic trails
- Mountain climbing for both beginners and experienced adventurers
- Camping in forested valleys or lakeside areas

Special Events and Local Festivals
Across the country, local communities and tourism boards organize commemorative events for Mountain Day.

- Guided nature tours led by local experts
- Cultural performances and craft workshops showcasing mountain traditions

Time with Family and Friends
For many, Mountain Day is a chance to slow down and spend quality time outdoors with loved ones. Families might enjoy picnics in highland parks, scenic ropeway rides, or visits to mountain hot spring resorts.
Travel and Tourism Boost
Because it falls during the busy Obon summer holidays, Mountain Day often becomes part of a longer vacation. Popular destinations such as the Japanese Alps, Hakone, and Mount Fuji see a surge of visitors, blending nature experiences with sightseeing, local cuisine, and traditional hospitality.

Mountain Traditions and Folklore
Japan’s mountains are not only natural landmarks—they are also home to centuries-old traditions, sacred beliefs, and captivating legends. These stories and practices reflect the deep reverence Japanese people have for the peaks that shape their landscape and way of life.
Deities of the Mountains
In Shinto belief, many mountains are considered the dwelling places of kami (gods or spirits). Among the most well-known are:
- Ōyamatsumi-no-Kami – the god of mountains, sea, and war, worshipped as the protector of those who venture into the highlands.
- Konohanasakuya-hime – the daughter of Ōyamatsumi-no-Kami, revered as the goddess of Mount Fuji and blossoms. She is associated with life, beauty, and the delicate yet fleeting nature of existence, and is enshrined at many mountain-related shrines across Japan.
Festivals and Sacred Rites
Mountains inspire numerous local festivals and religious events:
- Mount Fuji’s Yamabiraki – a “Mountain Opening” ceremony held in early July to mark the start of the climbing season, featuring Shinto rituals for safety and blessings.
- Ontake Worship – a centuries-old faith centered around Mount Ontake, where pilgrims wear white robes and ascend the mountain in sacred processions, chanting prayers and performing purification rites.
Such festivals blend physical endurance with spiritual devotion, making the act of climbing itself a form of worship.
Myths, Legends, and Supernatural Beings
Japan’s folklore is rich with mysterious beings said to inhabit the mountains:
- Tengu – long-nosed, red-faced spirits who are both protectors and tricksters, often seen as guardians of sacred forests.
- Yama-otoko – “mountain men” or wild giants who dwell in remote peaks.
- Yuki-onna – the “snow woman,” a ghostly figure who appears in blizzards, beautiful yet deadly.
These tales serve as both entertainment and cautionary warnings, reminding people of the power—and unpredictability—of nature.
From divine guardians to supernatural encounters, Japan’s mountains are more than scenic wonders. They are living cultural landscapes where nature, spirituality, and storytelling intertwine.
Tips for Enjoying Mountain Day as a Visitor
If you’re visiting Japan during Mountain Day and want to join in the celebrations—or simply experience Japan’s stunning mountain scenery—here are some tips to make your adventure safe, enjoyable, and culturally respectful.
Practice Good Mountain Etiquette
Japanese hikers value respect for nature and for others sharing the trail. Keep in mind:
- Carry out all your trash—leave nothing behind.
- Stay on marked trails to protect fragile ecosystems and avoid getting lost.

Bring the Right Gear
Even on a short hike, being properly equipped makes a big difference:
- Comfortable, weather-appropriate clothing and sturdy hiking shoes
- A reusable water bottle and snacks for energy
- A map or GPS device (some areas may have limited cell service)
- Rain gear, as mountain weather can change quickly
Prioritize Safety
- Check the weather forecast before heading out—mountain conditions can shift rapidly. - Many popular mountains now have live camera feeds available online, allowing you to check real-time conditions before you go.
- For longer or more remote hikes, file a climbing notification (tozan-todoke) with local authorities.
- Be aware of your limits and turn back if conditions worsen.
- Stay alert for wildlife and insects:
- In certain areas, bears (kuma) may be present—carry a bear bell or make noise to avoid surprise encounters.
- Watch out for leeches, snakes, and stinging insects such as hornets, especially in summer.
- Avoid approaching or feeding any wild animals, and keep a safe distance at all times.
By following these tips, you’ll not only have a safer and more enjoyable adventure—you’ll also experience the spirit of Mountain Day as the Japanese do: with respect, gratitude, and a deep connection to the natural world.
