Mount Fuji, Isand of Honshū, Japan,

Mount Fuji is located on the island of Honshū, is the highest mountain in Japan, standing 3,776.24 m (12,389.2 ft). It is the second-highest volcano located on an island in Asia (after Mount Kerinci on the island of Sumatra), and seventh-highest peak of an island on Earth. Mount Fuji is an active stratovolcano that last erupted from 1707 to 1708. The mountain stands about 100 km (62 mi) southwest of Tokyo and is visible from there on clear days. Mount Fuji's exceptionally symmetrical cone, which is snow-capped for about five months of the year, is commonly used as a cultural icon of Japan and it is frequently depicted in art and photography, as well as visited by sightseers and climbers.

Mount Fuji is one of Japan's "Three Holy Mountains"  along with Mount Tate and Mount Haku. It is a Special Place of Scenic Beauty and one of Japan's Historic Sites. It was added to the World Heritage List as a Cultural Site on June 22, 2013.According to UNESCO, Mount Fuji has "inspired artists and poets and been the object of pilgrimage for centuries". UNESCO recognizes 25 sites of cultural interest within the Mount Fuji locality. These 25 locations include the mountain and the Shinto shrine, Fujisan Hongū Sengen Taisha, as well as the Buddhist Taisekiji Head Temple founded in 1290, later depicted by Japanese ukiyo-e artist Katsushika Hokusai. 

Mount Fuji is an attractive volcanic cone and a frequent subject of Japanese art especially after 1600, when Edo (now Tokyo) became the capital and people saw the mountain while traveling on the Tōkaidō road. According to the historian H. Byron Earhart, "in medieval times it eventually came to be seen by Japanese as the “number one” mountain of the known world of the three countries of India, China, and Japan". The mountain is mentioned in Japanese literature throughout the ages and is the subject of many poems.

The summit has been thought of as sacred since ancient times and was forbidden to women until the Meiji era in the late 1860s. Ancient samurai used the base of the mountain as a remote training area, near the present-day town of Gotemba. The shōgun Minamoto no Yoritomo held yabusame in the area in the early Kamakura period.

The first ascent by a foreigner was by Sir Rutherford Alcock in September 1860, who ascended the mountain in 8 hours and descended in 3 hours.:427 Alcock's brief narrative in The Capital of the Tycoon was the first widely disseminated description of the mountain in the West. 421–27 Lady Fanny Parkes, the wife of British ambassador Sir Harry Parkes, was the first non-Japanese woman to ascend Mount Fuji in 1867. Photographer Felix Beato climbed Mount Fuji two years later. On March 5, 1966, BOAC Flight 911, a Boeing 707, broke up in flight and crashed near the Mount Fuji Gotemba New fifth station, shortly after departure from Tokyo International Airport. All 113 passengers and 11 crew members died in the disaster, which was attributed to the extreme clear-air turbulence caused by lee waves downwind of the mountain. There is a memorial for the crash a short distance down from the Gotemba New fifth station.

Today, Mount Fuji is an international destination for tourism and mountain climbing. In the early 20th century, populist educator Frederick Starr's Chautauqua lectures about his several ascents of Mount Fuji 1913, 1919, and 1923 were widely known in America. A well-known Japanese saying suggests that a wise person will climb Mt. Fuji once in their lifetime, but only a fool would climb it twice. It remains a popular symbol in Japanese culture, including making numerous movie appearances, inspiring the Infiniti logo, and even appearing in medicine with the Mount Fuji sign.

In September 2004, the manned weather station at the summit was closed after 72 years in operation. Observers monitored radar sweeps that detected typhoons and heavy rains. The station, which was the highest in Japan at 3,780 metres (12,402 ft), was replaced by a fully automated meteorological system. Mount Fuji was added to the World Heritage List as a Cultural Site on June 22, 2013. However, the inscription became controversial after two professors at the Mt. Fuji World Heritage Centre, Shizuoka, were forced to quit their jobs because of academic and racial harassment by officials of Shizuoka prefecture government in March 2018.

Mount Fuji is a very distinctive feature of the geography of Japan. It stands 3,776.24 m (12,389 ft) tall and is located near the Pacific coast of central Honshu, just southwest of Tokyo. It straddles the boundary of Shizuoka and Yamanashi Prefectures. Four small cities surround it: Gotemba to the east, Fujiyoshida to the north, Fujinomiya to the southwest, and Fuji to the south. It is surrounded by five lakes: Lake Kawaguchi, Lake Yamanaka, Lake Sai, Lake Motosu and Lake Shōji.They, and nearby Lake Ashi, provide views of the mountain. The mountain is part of the Fuji-Hakone-Izu National Park. It can be seen more distantly from Yokohama, Tokyo, and sometimes as far as Chiba, Saitama, Tochigi, Ibaraki and Lake Hamana when the sky is clear. It has been photographed from space during a space shuttle mission.

The summit of Mount Fuji has a tundra climate. The temperature is very low at the high altitude, and the cone is covered by snow for several months of the year. The lowest recorded temperature is −38.0 °C (−36.4 °F) recorded in February 1981, and the highest temperature was 17.8 °C (64.0 °F) recorded in August 1942.  Mount Fuji is located at a triple junction trench where the Amurian Plate, Okhotsk Plate, and Philippine Sea Plate meet. These three plates form the western part of Japan, the eastern part of Japan, and the Izu Peninsula respectively.The Pacific Plate is being subducted beneath these plates, resulting in volcanic activity. Mount Fuji is also located near three island arcs: the Southwestern Japan Arc, the Northeastern Japan Arc, and the Izu-Bonin-Mariana Arc.

Mt. Fuji's main crater is 780 metres (2,560 ft) in diameter and 240 metres (790 ft) in depth. The bottom of the crater is 100–130 metres (330–430 ft) in diameter. Slope angles from the crater to a distance of 1.5–2 kilometres (0.93–1.24 mi) are 31°–35°, the angle of repose for dry gravel. Beyond this distance, slope angles are about 27°, which is caused by an increase in scoria. Mid-flank slope angles decrease from 23° to less than 10° in the piedmont.

Scientists have identified four distinct phases of volcanic activity in the formation of Mount Fuji. The first phase, called Sen-komitake, is composed of an andesite core recently discovered deep within the mountain. Sen-komitake was followed by the "Komitake Fuji", a basalt layer believed to be formed several hundred thousand years ago. Approximately 100,000 years ago, "Old Fuji" was formed over the top of Komitake Fuji. The modern, "New Fuji" is believed to have formed over the top of Old Fuji around 10,000 years ago. The closest airport with scheduled international service is Mt. Fuji Shizuoka Airport. It opened in June 2009. It is about 80 kilometres (50 mi) from Mount Fuji. The major international airports serving Tokyo, Tokyo International Airport (Haneda Airport) in Tokyo and Narita International Airport in Chiba, are hours from Mount Fuji.

Approximately 300,000 people climbed Mount Fuji in 2009.The most popular period for people to hike up Mount Fuji is from July to August, while huts and other facilities are operating and the weather is warmest. Buses to the trail heads typically used by climbers start running on July 1.Climbing from October to May is very strongly discouraged, after a number of high-profile deaths and severe cold weather. Most Japanese climb the mountain at night in order to be in a position at or near the summit when the sun rises. The morning light is called 御来光 goraikō, "arrival of light".

There are four major routes to the summit, each has numbered stations along the way. They are (clockwise, starting North): Kawaguchiko, Subashiri, Gotemba, and Fujinomiya routes. Climbers usually start at the fifth stations, as these are reachable by car or by bus. The summit is the tenth station on each trail. The stations on different routes are at different elevations; the highest fifth station is located at Fujinomiya, followed by Yoshida, Subashiri, and Gotemba. There are four additional routes from the foot of the mountain: Shojiko, Yoshida, Suyama, and Murayama routes.

Even though it has only the second-highest fifth stations, the Yoshida route is the most-popular route because of its large parking area and many large mountain huts where a climber can rest or stay. During the summer season, most Mount Fuji climbing tour buses arrive there. The next-popular is the Fujinomiya route, which has the highest fifth station, followed by Subashiri and Gotemba. The ascent from the new fifth station can take anywhere between five and seven hours while the descent can take from three to four hours.

Even though most climbers do not climb the Subashiri and Gotemba routes, many descend these because of their ash-covered paths. From the seventh station to near the fifth station, one could run down these ash-covered paths in approximately 30 minutes. Besides these routes, there are tractor routes along the climbing routes. These tractor routes are used to bring food and other materials to huts on the mountain. Because the tractors usually take up most of the width of these paths and they tend to push large rocks from the side of the path, the tractor paths are off-limits to the climbers on sections that are not merged with the climbing or descending paths. Nevertheless, one can sometimes see people riding mountain bikes along the tractor routes down from the summit. This is particularly risky, as it becomes difficult to control speed and may send some rocks rolling along the side of the path, which may hit other people.

The four routes from the foot of the mountain offer historical sites. The Murayama is the oldest Mount Fuji route and the Yoshida route still has many old shrines, teahouses, and huts along its path. These routes are gaining popularity recently and are being restored, but climbing from the foot of the mountain is still relatively uncommon. Also, bears have been sighted along the Yoshida route. Huts at and above the fifth stations are usually manned during the climbing season, but huts below fifth stations are not usually manned for climbers. The number of open huts on routes are proportional to the number of climbers Yoshida has the most while Gotemba has the fewest. The huts along the Gotemba route also tend to start later and close earlier than those along the Yoshida route. Also, because Mount Fuji is designated as a national park, it is illegal to camp above the fifth station. There are eight peaks around the crater at the summit. The highest point in Japan, Ken-ga-mine, is where the Mount Fuji Radar System used to be (it was replaced by an automated system in 2004). Climbers are able to visit each of these peaks.
