Mountain Day Hero

John Muir

John Muir (1838–1914) was a Scottish-American naturalist, author, environmental philosopher, glaciologist, and early advocate for the preservation of wilderness in the United States. Known as the 'Father of the National Parks,' his activism helped establish Yosemite and Sequoia National Parks. His writings, including 'My First Summer in the Sierra,' eloquently championed the spiritual and ecological value of mountains.

History of Mountain Day

Japan is well ahead of the rest of the world when it comes to its lifestyle and technological advancements. But despite their peak urbanization, Japanese people are quite grounded in their roots and perceive themselves as being more connected to nature than other developed nations. 

The planning of Japan’s dense cities and its culture developed on the flat land found near the sea, but that’s only one part of the country’s extraordinary landscapes. Hikers, trekkers, and activist groups, like the Japanese Alpine Club, advocated for the cause to have a Mountain Day to celebrate the country’s mountainous geography. 

In 2014, the idea for Mountain Day or ‘Yama-no-Hi’ was conceived and, in 2016, the day became Japan’s latest public holiday. August 11 was established as the day for the holiday’s observance because, in the Chinese characters used for writing Japanese — Kanji,  the number eight resembles a mountain and the number 11 resembles two trees. 

There weren’t many traditional activities or ceremonies for the inception of Mountain Day in Japan. The inauguration ceremony took place in the Japanese Alps at Kamikochi in Matsumoto, Nagano. The day is celebrated on August 11 but, if the date falls on a Sunday, the holiday will be observed on the following Monday.

Mountain Day Activities

  1. Take a spin on your mountain bike

    Whenever we think of mountains, we only seem to consider hiking or climbing them. But there's another scenic way to take in the splendors of mountain vistas — mountain biking. Just make sure to get your bike checked out thoroughly before you head out and don't forget your helmet!

  2. Go camping

    Sure, it's important to get your exercise when you visit mountainous areas. But if you're not the most in-shape person around, consider just packing up some gear and camp out near the base of a mountain. You get the same benefit of refreshing mountain air and beautiful, starry nights without the wear and tear on your body. Once you settle in, collect your bestie and take a nice, long walk.

  3. Walk, hike and climb

    For those who consider themselves die-hards, there's nothing better than gearing up for a daylong walk, hike or climb up a mountain. Bring your camera because you don't want to miss a thing but be careful and don't get too close to the edge. If you're lucky enough to get all the way to the summit, sit and bask in the stillness and the vision of peace from on high.

3 Reasons Why Japan's Mt. Fuji Captures Our Imagination

  1. It's more than a mountain — it's a volcano

    In fact, Mt. Fuji consists of three active, separate volcanoes: Komitake at the base, Kofuji dominating the middle and Fuji at its peak.

  2. It was off limits to women climbers until 1868

    Due to Mt. Fuji's religious significance, women were banned from climbing the mountain until the Meiji Restoration in 1868. Later, Lady Fanny Parkes became the first western woman to get to the summit the following year.

  3. It's surrounded by lakes

    There are five lakes surrounding Mt. Fuji at approximately 1,000 feet above sea level with wondrous views of this iconic, Japanese symbol.

Why We Love Mountain Day

  1. Mountain lovers fought for it

    Various mountain groups pushed hard for an official day to cast work aside and head to the mountains for fun and exercise. Additionally, the Japanese government saw the holiday as a boost to the economy — a win-win all around. With its rocky terrain, Japan promotes Mountain Day on August 11 as a natural fit for groups seeking the serenity of the region's various mountains. Mountain Day devotees also believe that the written numerical characters for 11 resemble either a mountain top or two trees.

  2. It's an excuse to climb Mt. Fuji

    Mt. Fuji is Japan's most famous mountain and Mountain Day is sandwiched in between Mt. Fuji's climbing season, from the beginning of July until the beginning of September. That's an ideal time for the approximately 300,000 annual hikers and mountain climbers to pay homage. At that time, there's no trace of snow on the trails and the weather is balmy.

  3. Japanese mountains are sacred spaces

    Japan has three holy mountains — Mt. Tate, Mt. Haku and of course, Mt. Fuji. This mountain was first climbed by a monk in 663 A.D. Mountains have long been places of meditation and worship by Shintoists since the seventh century.
