Hashiriyu Hot Spring Source, Shizuoka

Speaking of Atami Onsen Hot Spring Resorts in Shizuoka Prefecture, it is one of the most popular hot springs in Japan. Did you know that Mt. Izusan, Atami City, has a “cold-hole source” that is said to have bathed MINAMOTO no Yoritomo (12th century samurai)? A cave where hot water springs like the heartbeat of the earth. You can also enjoy the source spring while hitting the sea breeze at the foot bath nearby.
“Hashiriyu Hot Spring” is exposed from the back of a cave with a depth of 5 meters. Anyone can visit the cave for free, but the foot is bad and the heat inside the cave is great, so it’s a bit harsh for small children and the elderly.
Until the Meiji Era, a shrine was built to gather faith and protect the source as a god of Izusan-jinja Shrine. Even now, the amount of hot water has not declined. You can see abundant springs.
“Hashiriyu Onsen” at Izusan Onsen Hot Spring Resorts is a hot spring with a history that is said to have been discovered around 720 by Ennoozunu, the trainee of the shrine. Azuma Kagami, the history of the Kamakura period, has been introduced to Japan’s three major ancient springs, along with Dogo Onsen in Ehime and Arima Onsen in Hyogo. Izu lords such as MINAMOTO no Yoritomo, Masako HOJO and Soun HOJO must have enjoyed this hot water.
This source is said to have flowed from the hillside into the sea like a waterfall, and is a side-hole type spring that is rare in Japan. This is why it is called “Hashiriyu” (Running hot water). It seems that it is not clear why it was erupted in the side hole type, but it is thought that the rock surface eroded on the coast erupted the hot spring.
Currently, the Izu Peninsula is carrying out various activities with the aim of accrediting a global geopark under the title of “Volcano Gifts from the South”.
The source in this cave shows the scenery as if you were looking inside the earth. It can be said that this is a recommended spot for a geopark.

You can visit the source that gushes abundantly

The “Hashiriyu” of Izusan Hot Springs in Atami, which is also counted as one of Japan’ s three great old springs, is a hot spring source that was discovered 1,300 years ago. It is a rare source of the lateral hole formula, and the source springing from the mountain ran away as if it flew to the coast, so it was named running water. Until the Meiji period, faith was gathered as Izusan Shrine’s sacred hot water, and the shrine to protect the source was also built. Even now, the amount of pouring hot water is not waning. You can visit the source that gushes abundantly.

As if you enter a hot spring sauna

Although you can enter freely in the cave, it is only about 1.5 meters high, so adults will walk in a slightly crooked posture. Moreover, the inside of the cave is full of steam which can not see the end. However, since the sight of the lower part of the cave is open, you can proceed while checking the front by bending. In the middle of the cave, the warmth of the steam from the source gives you a sweat as if you enter a hot spring sauna.

The place you can feel the mystery of nature

There is a stone tank at the end of the cave, and a source of 70 degrees Celsius is laid in it. The amount of hot water to gush per day is around 7,000 tons. It is a place where you can feel the mystery of nature.

You can feel the beating of the earth

Peeping inside the stone tank, you can hear a sound and you can see that the source is blowing up. Currently it is not a self-blowing jet, but hot water drawn from the source spouts 140 liters per minute. It is really surprising to say that in the past it was much more hot water than now, it was falling into the sea like a waterfall through the cave. This is the spot where you can feel the beating of the earth.

The body feels comfortable with a refreshing beach wind

There is a footbath that has withdrawn its source in a place 20 meters away from the entrance of “Hashiriyu”. It is a footbath like the observatory which is located a little higher place. It is a small footbath that only about 3 people can enter, but the view from there is the best. The feet are warm with hot water and the body feels comfortable with a refreshing beach wind.
And the ocean which spreads before your eyes is very nice.
