Hot Springs

A passion for cold springs and carbon dioxide

Kosaka's carbonated spring has more than 1,000 PPM and is recognized as a high-concentration carbonated spring "recuperation spring".

However, since it is a cold mineral spring with a temperature of 12.2℃,
In our 130-year history, we have never been able to create a bathtub that allows bubbles to stick to your body while bathing.

Now in its fourth generation,
We have been dealing with the issue of cold springs and carbon dioxide for over a decade.
They came up with a method to heat the water while leaving the carbon dioxide in, which led to the development of the carbonated spring water at Sengakukan.
Our wish is to deliver something better, something genuine, something meaningful.

  • Indoor bath: Simple carbon dioxide cold mineral spring

    The indoor bath is a two-tank bath with different temperatures of about 40℃ and 36℃.

    ~Warm water, but Yuzame Senyoi~
    As the old saying goes, carbonated springs have the effect of promoting blood flow.
    It is said that the perceived temperature is 2°C higher.

    It may feel a little warm and cold at first, but after about 10 to 15 minutes 
    Taking a deep bath increases blood flow and warms the body from the inside.

    The balance of the autonomic nervous system is improved, and the parasympathetic nervous system becomes dominant.
    It is said to improve the quality of sleep and also reduce stress.

    Promotes blood circulation, improves metabolism, relieves fatigue, improves skin condition, etc.
    It is expected to have many positive effects on the body.

    Here is the explanation for bathing (You can also drink it.)

  • Drinking fountain

    The carbonated spring water is a "drinkable spring water" approved by the health center.
    It has been said since ancient times that carbonated springs are better than stomach medicine.
    This shows that carbonated springs have been popular as an anti-inflammatory since the days when the efficacy of the springs was uncertain.

    The carbonated springs in this area come from different wells at each lodge, and each has different ingredients, salt content, and iron content.
    Therefore, some sakes are more suitable for drinking and other cooking purposes than others, which I think makes them unique and interesting.
