Spring, summer, autumn, winter. Nature of Oshino discovering new beauty every season.

Nature that various plants and insects, fish, animals and human being coexist from the unique location requirements in Oshino-mura. The foot of obvious Mount Fuji spreads out in southwestern direction and is refreshing plateau-like basin among Mt.Ishiwariyama of 1413.0m on Mt.Syakushiyama, the east side of 1597.6m in the north side. It is 936m at altitude of center. Flowering of cherry tree is about the beginning of May, too, and this is the time same as Sapporo-shi of Hokkaido every year.
And the source of Katsuragawa river (the Sagami River) becomes Lake Yamanaka on map, but it may be said that Oshino Hakkai and Sin-Nashogawa river flowing across Oshino-mura are the substantial source. This water runs and, via Sagamiko, Lake Tsukui, becomes the Sagami River, and it flows through Kaneyama no waterfall when to Gulf of Sagami. It is long flow of the river of driftage 210 kilos really. By the way, Katsuragawa river is one of the spring creeks (river becoming the same river from spring source) having only three places in Japan.
There are many Ranunculus aquatilis and Vallisneria asiatica, aquatic plants including fen cress by having abundant water in this way. In addition, in the river flowing through Oshino, water temperature becomes constant for spring through the year and is famous as fly fishing area eminent in the country that guest visits from foreign countries because we keep environment that is comfortable for the bait and aquatic insect that it is for fish. Some small bridges hang over brook with nature on, embankment of gravel. Private house of roof of thatch which many places are still dotted with. It is Times lip to the good old days. Such mysterious place, Oshino-mura.

We confront Mount Fuji from heap of Oshino

Nijumagari pass

1,150m above sea level. It is shooting point of Mount Fuji which scenery from mountain pass is splendid, and is famous as "Oshino Fuji" by photographer, Koyo Okada who loves Mount Fuji from Oshino-mura deeply, and continued taking. Nijumagari pass was mountain pass where many hikers came and went from old days located at Mt.Oideyama, Mt.Ohirayama, the terminal of Mt.Ishiwariyama hiking course. According to the name, way has many winds. However, we can take a drive to mountain pass by car casually as forest road is maintained now.

Mt.Syakushiyama

[Mt. 100 Yamanashi] 1597.6m
In mountains more than 1500 in the prefecture, it is located in short distance at only 15km most from Mount Fuji. Because there is not high tree on the mountaintop, it is one-on-one and can face Mount Fuji which did Yoshida-Osawa in the front. And vast panorama which the Northern Alps can look at from between Tanzawa Range, Kurodake and Mitsutoge to central vein, the east of Oku-chichibu to Shirane Mountains, the Southern Alps, the north to the west if they look around around the circumference. As climb is sudden, it is suitable for intermediate people.

Mt.Ishiwariyama

[Mt. 100 Yamanashi] 1413.0m
Just before the mountaintop, huge stone of 15m in height is broken right in the two. There is Shinto shrine there, and it is said that good luck opens in crack when we go through on foot three times. But that dirty person cannot go through. Because the Sun-Goddess bans evil deed of Susanoo-no-Mikoto, we hide in Iwato, and, as for this broken huge stone, the world is said to be the famous legendary stage which became dead darkness and is called AMATOIWA. It is the mountaintop from Shinto shrine for approximately 20 minutes. Beginner direction.

Waterfall of Kaneyama

Beautiful waterfall of Article 2 that water of Oshino Hakkai and Sin-Nashogawa river flows into. We float leaf of colored leaves in autumn and become scenery that flavor is deep. Drop is not big at all as approximately 10m, but waterfall only in the neighborhood of upper reaches of Katsuragawa river. This waterfall was described in "Kaikokushi", but seemed to call bell ga deep water not waterfall in old days. It can be called deep water, and this basin of a waterfall has considerable area and depth. And all the rocks that waterfall runs are lava which flowed out when Mount Fuji erupted.

Large rice mortar, small rice mortar

Parasite volcano (side volcano) of Mount Fuji totally rice mortar-shaped according to the name. Large rice mortar consists of sukoria which began to blow of Mount Fuji and is said to be cinder cone. Altitude is 985m, but stone implements more than 3,000 years ago are discovered how near the crater at the mountaintop. Scale is smaller than large rice mortar, and small rice mortar can enter eruption hole trace. It is big, and, in the crater, earthenware vessels of Jomon period are discovered in small rice mortar with 50m in comparison with size of cinder cone a lot to east and west.

The formation of dramatic Oshino Hakkai

In around Oshino-mura, the very large sea would open now from 24 million years to 5,100,000 years ago, and intense submarine volcano was active in the bottom of the sea and let the seas pile up with sediment of thick submarine volcano. When it was around 5 million years ago, magma rose to deep underground, and abyssal rocks body of whitish quartz diorite penetrated and gradually pushed up land, and land opened, and, from Gulf of current Suruga, we hung in Kanagawa from Oshinomura, Fujiyoshida-shi, Tsuru-shi, Otsuki-shi, Uenohara-shi, and the Katsuragawa river straits were made. Becoming went ahead through land, and the Oshino-mura whole area became land afterwards, too. Mount Ashitaka continued commencing with volcanic activity of the south, and Old Fuji volcano was active to the south of small mountain rising to a great height volcano with small mountain rising to a great height volcano filled up under Mount Fuji from around 80,000 years ago, and big Old Fuji volcano was made hundreds of thousands of years ago during tens of thousands of years. Lava and volcano gravel of Old Fuji volcano of this time deposit on base of Oshino basin, Misaka formation thick, and they become the retention layer of Oshino depths basement Shuihu. For approximately 20,000 years of last years of this Old Fuji volcanic activity, old Lake Oshinoko was formed in interval approximately 10,000 years before the early period of Shinfuji volcanic activity, and the class of diatom clay containing fresh water-related diatom fossil deposited to approximately 2m. Lava of the early period of Shinfuji volcanic activity flows near the present Oshino Hakkai, and old Lake Oshinoko of the surface of the earth gradually becomes extinct and becomes current Shuihu under the ground. Groundwater of permeable layer of Shinfuji volcano and groundwater waiting for pressure in impermeable layer of Old Fuji volcano sediment gush out together, and a large quantity of groundwater from Mount Fuji supplies water such as Oshino Hakkai wealthily.
