What is the mystery behind the mysterious world's largest active volcano?

Mt. Fuji is located 80,000 meters southwest of Tokyo, 26,000 meters south of the Pacific Ocean, and the main peak is about 3,776 meters above sea level, making it the first peak in Japan. It straddles Japan's Shizuoka Prefecture and Yamanashi Prefecture and is one of the largest active volcanoes in the world.

At present, it is also one of the most active volcanoes that human beings pay attention to, seemingly a silent and gentle Mt. Fuji, but it is one of the most restless volcanoes, and it has been more than three hundred years since its last eruption. The eruption was so severe that 80,000 meters away, Tokyo was covered with a layer of 15 cm thick volcanic dust.

The foothills have a circumference of about 125 km, and together with the broad lava flows in the foothills, the diameter of the bottom is about 40-50 km. Around the rim of the crater around the summit are the "Fuji Eight Peaks", namely Kensei, Shirayama, Kusushi, Dairi, Izu, Shōshō, Komagata, and Mitake. Mt. Fuji belongs to the Fuji Volcanic Belt, a volcanic chain that starts from the Mariana Islands and reaches northern Honshu via the Izu Islands and the Izu Peninsula.

There are more than 2,000 species of plants on the mountain, with obvious vertical distribution, subtropical evergreen forest below 500 meters above sea level, temperate deciduous broad-leaved forest at an altitude of 500-2000 meters, cold temperate coniferous forest at an altitude of 2000-2600 meters, and alpine dwarf curved forest belt above 2600 meters above sea level. The summit is covered with snow all year round.

Every summer, thousands of Japanese people worship at the summit shrine. This mountain is also the main scenic area of Fuji Hakone- Izu National Park. Due to the charm of Mt. Fuji itself and its status in Japan, people have long wanted to declare it a World Natural Heritage Site.

Quest for mysteries: 1. How many times has Mt. Fuji erupted as an active volcano?

Mount Fuji is conical in shape and has erupted 18 times, the most recent of which was in 1707. Now, although it is dormant, it still has a jet phenomenon, with an average of 80 earthquakes per year.

Wonderland Treasures

【Fuji Five Lakes】

At the northern foot of Mt. Fuji is the Fuji Five Lakes, which, from east to west, are Yamanaka Lake, Kawaguchi Lake, West Lake, Shojin Lake, and Honsu Lake. Among them, the mountain lake is the largest, with an area of 6.75 square kilometers. There are many sports facilities on the lakeside, such as tennis, water skiing, fishing, camping and boating. In the southeast of the lake, Oshino Village has 8 ponds, including Yongchi Pond and Mirror Pond, collectively known as "Oshino Hakkai", which are connected to Lake Yamanaka.

Lake Kawaguchi is the earliest of the Five Lakes and has become the center of five lakes sightseeing. Pelican Island in the lake is the only island in the five lakes. There is a shrine on the island dedicated to the safe delivery of pregnant women. There is also a 1,260-meter-long bridge across the lake. The reflection of Mt. Fuji reflected in Lake Kawaguchi is known as one of the wonders of Mt. Fuji.

West Lake, also known as "West Sea", is the quietest lake among the five lakes.

Lake Shojin is the smallest of the Fuji Five Lakes, but its style is the most unique, with many towering cliffs and complex terrain on the shores.

The lake is the deepest, reaching a maximum depth of 126 meters. The surface of the lake is not frozen all year round, and it is dark blue.

【White Waterfall】

In the southwestern foothills of Mt. Fuji, there is the famous White Waterfall, which drops 26 meters and divides into more than ten streams from the rock wall, as if countless chains of white beads fall from the air, forming a rain curtain more than 130 meters wide, which is quite spectacular.

Since the water of the White Waterfall is formed by melting snow, even in the very hot summer, the water temperature is only about 10 °C, so it is the clearest and coolest waterfall in Japan.

【Otoshi Waterfall】

The southern foothills of Mt. Fuji are a vast plateau with green grass, a tourist pasture with cattle and sheep. At the southwestern foot of the mountain is the famous Otoshi Waterfall. The sound stop waterfall is like a huge pillar crashing down from a high place, and the sound is like thunder, shaking the earth.

【Volcanic Cave】

Due to the eruption of the crater, Mt. Fuji has formed countless caves at the foot of the mountain, and some of the caves still have the phenomenon of gas jets to this day. The walls of the most beautiful Cave of Fugaku are covered with stalactite icicles that do not melt all year round, and are regarded as a rare spectacle of "10,000 years of snow". There are two large and small craters on the summit, and the diameter of the large crater is about 800 meters and the depth is 200 meters. When the weather is clear, watching the sunrise and watching the sea of clouds at the top of the mountain is an indispensable excursion for tourists from all over the world to visit Japan.

⊙ Quest:

1. At present, which mountain in Fuji and China are friendly mountains?

On November 12, 2007, Tai'an City, Shandong Province, China, and the Japan Fuji Mountain Association held a signing ceremony in Tokyo, Japan, where Mount Tai and Mt. Fuji were formed as "Friendship Mountain". Therefore, Mount Taishan and Mount Fuji are friendly mountains.

Allusions to legends

【Origin of the name Mt. Fuji】

According to legend, in ancient times, there was an old man who cut bamboo, and he found a little girl of about 3 years old in the bamboo deep in the mountain forest. Three months after bringing her home, the little girl turned into a very beautiful girl, attracting many young men to propose to her, and even the emperor joined the marriage proposal, but the girl refused.

It turned out that the little girl was a fairy in heaven, and was relegated to the mortal world for 3 years for violating the precepts. On the night of the fifteenth full moon of August of the third year, she atonement expired and returned to the Heavenly Palace. Before leaving, she left the emperor a bag of elixirs for immortality. And the overly sad emperor ordered the medicine to be burned in the place closest to the sky. However, this bag of medicine is always burned, and it is always smoking.

Therefore, the mountain that was chosen to burn medicine was named "Immortal" or "Unique" Mountain. In Japanese, "immortal" and "fuji" are pronounced the same as "Fuji", hence the name Mt. Fuji.

【Thirty-Six Views of Fugatake】】

During the Edo period (1603-1868), the famous Japanese ukiyo-e painter Katsushika Hokusai created 46 consecutive prints based on Mount Fuji around 1831, "Thirty-Six Views of Fugaku". Originally, the painter planned to paint only 36 paintings according to the title, but later because of its popularity, he added 10 more paintings. Among them, the magnificent works depicting Mt. Fuji's majestic works "Kai Feng And Fast" and "White Rain Under the Mountain" are widely known, and these two paintings are also affectionately known as "Akafuji" and "Black Fuji"
