Minari Kaihin Onsen is a natural outdoor hot spring located in the Dan-hokka district at the foot of Mt. Eshan in Hakodate, Hokkaido. The most striking feature of this location is the stone bath, which is built directly onto the coastline overlooking the Pacific Ocean. Because the bath is located so close to the water, it can actually be submerged by the sea during high tide. This creates an environment where you can feel truly one with the grand, sweeping nature of Hokkaido. The site is equipped with separate changing rooms for men and women, making it a well-known spot for those wishing to soak while enjoying the raw, unadulterated landscape.
This area lies at the foot of Mt. Eshan (Kezan), a volcano that shapes the southern part of Hakodate. The volcanic topography of the region has created a rich, natural environment, and this hot spring area has long been cherished as a place to experience the blessings of nature. The style of an outdoor bath placed directly on the shore is a way of maximizing the local environment, existing as a part of the natural landscape that changes its expression with the seasons and the ebb and flow of the tides.

The greatest highlight is the expansive, open view of the Pacific Ocean right before your eyes. Soaking in a natural landscape while listening to the rhythmic sound of the waves is a stark contrast to the experience of urban hot spring facilities. During high tide, you may witness a spectacular sight where the bath seems to merge with the ocean. The way the scenery shifts with the movement of the tides allows you to observe the changing moods of the sea. The bath's placement along the coast provides a visual and physical sense of Hokkaido's natural abundance.
Because the accessibility of the bath changes depending on the tides, it is highly recommended to check a tide table before your visit. The scenery changes beautifully with the seasons: from the vibrant blue of the sea and sky in spring and summer to the more rugged, intense expressions of nature in autumn and winter. Regarding the time of day, visiting during low tide is essential for bathing, while sunrise and sunset offer breathtakingly beautiful light changes that enhance the natural scenery.

Here, you can enjoy a direct connection with nature through a natural outdoor soak. Since changing rooms are available, visitors can enjoy the experience by wearing swimwear. Warming your body in the open air while feeling the sea breeze and the sound of the waves provides a refreshing escape from daily life. It is also a wonderful place to simply observe and appreciate the surrounding natural environment.
The area surrounding Minari Kaihin Onsen is a beautiful, nature-rich region in southern Hakodate. It features volcanic landscapes like Mt. Eshan and beautiful, winding coastlines. Located a short distance from Hakodate city center, it is a perfect destination to include in a sightseeing route focused on driving or nature walks through the Hokkaido wilderness.
To use the hot spring, you must bring your own swimwear. While changing rooms are provided, please be mindful of the environment as this is a public natural space. Because the availability of the bath changes with the tides, we strongly recommend checking the tide schedule in advance.
