Naso Valley is a valley located near the 6th station of Mt. Chokai, and is approximately 300m to 500m deep. The river has carved out the lava layer over many years, creating a V-shaped valley. The sheer cliffs are piled up with lava from Mt. Chokai, which has erupted repeatedly since about 600,000 years ago, creating a mille-feuille-like appearance. The lava at the bottom of the gorge is said to be 400,000 to 450,000 years old, and the top is said to be around 100,000 years old.

The Naso Valley is impressive just looking up from below, but from the Hokotate Observation Deck at the 5th station of Mt. Chokai, you can see the Naso Valley from above. The valley that can be seen below Hokodate Observation Deck is 337m deep, and Tokyo Tower (333m) can fit completely inside.

Kamigo's warm water channels raise cold snowmelt water to a temperature suitable for rice cultivation

Thanks to the construction of warm waterways, cold water becomes warmer, allowing crops to grow ©Mt. Chokai/Tobishima Geopark

Kamigo's warm canals were invented by farmers who used the cold snowmelt water of Mt. Chokai for rice cultivation, in order to somehow warm up the extremely cold water to a temperature suitable for rice cultivation. The snowmelt water on Mt. Chokai is around 10 degrees Celsius even in summer, which is too cold for rice cultivation, making it difficult for rice to grow well. Therefore, a method was devised to make the waterway wider, shallower, and with steps to warm the melted snow water by exposing it to sunlight. Thanks to this, the water temperature rose by 2 to 8 degrees Celsius, and rice yields increased dramatically.

The heated waterway was built in 1927 (Showa 2), with a length of 648m, and was the first heated waterway in Japan. Since then, many hot waterways have been completed, including Omori Onsen Waterway and Mizuoka Onsen Waterway, with a total length of 6.28km.

The “Innai Oil Field” once boasted one of the highest production volumes in Japan.

In-hospital oil field
Tchaikovsky's numerous wells represent the abundance of oil production. “In-house oil field” in its heyday Mt. Chokai/Tobishima Geopark

The Innai Oil Field (Innai, Nikaho City) was once one of the largest oil fields in Japan, and its former site was selected by the Economy, Trade and Industry Award as part of the Modern Industrial Heritage Group 33, ``Japan's modern oil industry that began in the Kanto-Koshinetsu region, including Niigata.'' It has been preserved as a "modernization industrial heritage site that tells the story of the history of the world."

Japan's oil industry began with mining in Echigo (Niigata Prefecture) in the late 16th century. It began in earnest in the early Meiji period, when engineers were invited from the United States to investigate oil reserves mainly in Koshinetsu and northern Japan.

The first oil produced after the Meiji era was Sagara Town in Shizuoka Prefecture (Sagara, Makinohara City) in 1873. Later, oil fields with large reserves were discovered on the Sea of ​​Japan side of Niigata Prefecture, and Japan's oil industry boomed.

At the end of the Meiji era, the wave of oil development reached not only Niigata Prefecture but also Akita Prefecture. An oil field discovered in Akita City in 1914 (Taisho 3) produced a large amount of crude oil gushing out. Many oil companies took notice of this, and an oil development boom began in Akita Prefecture.

It seems that it was discovered in the late Meiji period that there was an oil field within Nikaho City, but trial drilling began in earnest in 1922 (Taisho 11), and oil was successfully extracted the following year in 1923. In 1932 (Showa 7), Asahi Oil (the predecessor company of Showa Sekiyu [Gendemitsu Kosan]) succeeded in extracting 8 kiloliters of oil per day.

The in-house oil field reached its peak in 1935 (Showa 10), with a total annual production of 110,000 kiloliters, making it one of the largest oil fields in Japan. After that, oil production gradually decreased due to resource depletion and decline in international competitiveness, and the mine was closed in 1995.

Modernization Industrial Heritage Group 33 ``Modernization Industrial Heritage Sites that tell the history of Japan's modern oil industry that began in the Kanto-Koshinetsu region such as Niigata'' includes the ``Internal Oil Field Related Heritage'' and the `` Toyokawa Oil Related Heritage '' (Katagami, Akita Prefecture). City), `` Kanazu Oil Field Related Heritage (Oil no Sato Park)'' ( Akiba Ward, Niigata City, Niigata Prefecture), ``Amase Oil Field Related Heritage '' (Izumozaki Town, Niigata Prefecture), and `` Sagara Oil Field Related Heritage '' (Makinohara City, Shizuoka Prefecture). Selected.
