Under the supervision of Professor Shinya Hayasaka, a specialist in spa therapy, you can prepare your body with a bathing method that effectively incorporates the power of hot springs.

Since 2017, we have been developing services related to hot springs at facilities nationwide as “Uruhashi Hyundai Yuji” with the aim of making it possible to experience hot spring therapies that have been handed down in Japan for a long time at modern hot spring inns. The staff who are familiar with hot springs, called “Kai no Yumori,” play a central role in developing and evolving new services year after year.

In addition to bathing in hot springs, you can enjoy the hot springs of Japan, such as the suggestion of eating shaved ice, which is a summer tradition, the original beer that makes the hot springs a blissful time, the ginger tea recommended for measures against the cold in the summer, and the modern hot spring exercises performed under the summer sky.

Recommended bathing method for summer
<For early summer>
In early summer (around June), taking a good bath in a hot spring will help prevent heat stroke. After taking a full-body bath at 40°C for about 15 minutes and sweating for about 2 weeks, including hot springs and bathing at home, the body becomes accustomed to heat by saying “heat acclimatization”. increase. As heat acclimatization progresses, heat stroke can be prevented and summer can be survived energetically.

<For midsummer>
The temperature is high during the summer, and because the room is air-conditioned, the temperature difference between the outside and the room is large. This causes stress on the body, stimulates the sympathetic nerves, and tires the autonomic nerves. When the sympathetic nerves are overwhelmed, the gastrointestinal motility also deteriorates, and the appetite is lost, resulting in the so-called summer heat fatigue. Sometimes it’s hard to sleep at night in the summer.

Taking a relaxing bath in a lukewarm hot spring up to 40°C suppresses the excitement of the sympathetic nerves, and conversely enhances the parasympathetic nerves and reduces the fatigue of the autonomic nerves. Increased parasympathetic activity also improves gastrointestinal tone. Taking a bath will lead to a good night’s sleep.

Summer programs and experiences that can be enjoyed in the world

Summer tradition, local shaved ice

Kakigori is a popular summer food that is perfect for cooling down. The world proposes a style of eating while taking a footbath so as not to inadvertently cool your body too much this summer. It is a new way of eating that is similar to the old-fashioned idea of “head cold foot fever”. For the ice to be carved, “pure ice” made by an ice specialty store is used. It is said that “pure ice” does not hurt your head.
