Kaike Onsen: Spending Time with Mt. Daisen and Sea of Japan at a Seaside Hot Spring Resort Overlooking Yumigahama

Kaike Onsen, on the coast of Yonago City in Tottori Prefecture, is a hot spring resort on the shore of the Yumigahama Peninsula facing the Sea of Japan. Its appeal lies in the white sandy beach and the Sea of Japan spread out before it, and the view of the famous Mt. Daisen in the distance. It has developed as a hot spring resort making the most of its open seaside location. Boasting an abundant volume of hot water, it is also known as the birthplace of the triathlon in Japan, and is a leading hot spring destination of San in.

Highlights

Kaike Onsen is a relatively new hot spring area, said to have begun when water welling up from the sea was discovered in the Meiji era. The salt-containing chloride spring rising along the coast has long been valued as water that warms the body well. Blessed with an abundant supply, it grew into one of the finest hot spring resorts in San in, lined with ryokan and hotels that make the most of the seaside setting.

Its greatest appeal is, above all, the magnificent scenery. The Sea of Japan spreads out before the hot spring district, with a continuous white sandy beach. In the distance you can see the graceful form of Mt. Daisen, also called Hoki Fuji, letting you enjoy the spectacular scenery of both sea and mountain at once. The sun setting into the sea is exceptional, and the beauty of the ever-changing sky and sea leaves a deep impression on your journey.

Enjoying the Seasons

There are different charms by season: summer for sea bathing, and winter for savoring delicacies such as Matsuba crab. In summer the beach bustles with swimmers, and strolling while gazing at the sea is pleasant. Kaike Onsen is also known as the place where Japan first triathlon was held in 1981, and every summer the Kaike Triathlon draws participants from across the country. Fresh seafood is another treat unique to a seaside hot spring; in winter you can enjoy San in delicacies including Matsuba crab.

Access and Basic Information

Access is about 20 minutes by bus or taxi from Yonago Station on the JR San in Main Line. It is also well connected from Yonago Airport and the San in Expressway. Its location is convenient as a base for nearby sights such as Mt. Daisen, Mizuki Shigeru Road in Sakaiminato, and the Izumo area.

Practical Travel Notes

While chloride springs keep you warm and slow to cool, they can also cause bathing fatigue, so be mindful to hydrate frequently and bathe without overdoing it. The coast can be windy on some days, so a layer to throw on is reassuring when strolling. Many inns offer day-use bathing, so you can enjoy the hot spring and sea views without staying overnight. As the swimming season and holidays get crowded, booking early is recommended.

A Word of Advice

Kaike Onsen appeal is that you can enjoy the spectacular scenery of sea and mountain, its abundant waters, and San in delicacies all at once. Take an evening stroll along the shore and spend a soothing resort moment gazing at Mt. Daisen and the sun setting into the Sea of Japan.
