The quiet murmuring of the mountains and a relaxing hot spring bath await you

The unique Onto Onsen,, located in the Nagato-Yumoto Hot Spring resort, reopened after a grand renewal in March 2020. This hot spring is said to be the oldest in Yamaguchi Prefecture, boasting a history of nearly 600 years. The Chikurin-no-Kaidan, or bamboo grove stairway, connects the Nagato-Yumoto Hot Spring parking lot along National Route 316 with the main street of the resort. The hundreds of bamboo stalks create an atmosphere of calm. The path is lined with lanterns designed after a motif based on the nearby Otozure river flowing next to them.

Overview and History Onto Onsen

The Nagato-Yumoto Hot Spring is one of the most famous hot spring resorts in Yamaguchi Prefecture. And the Onto hot spring that symbolizes the resort is enriched by a complexity of history and legends. Let’s unravel the mysteries together.

This is the men’s bath at the Onto Onsen. The figure of Sumiyoshi Daimyojin sits atop the bedrock from which the hot spring water flows. The Shimenawa woven straw piece comes from the Sumiyoshi Shrine in Shimonoseki, Yamaguchi Prefecture. The women’s bath is located just on the other side of the wall, and features roughly the same design.

Onto, the oldest hot spring in Yamaguchi Prefecture
A famous hot spring gifted by the god Sumiyoshi Daimyojin

 

The Otozure river flows through the middle of the Nagato-Yumoto hot spring resort. The Onto Onsen located on its banks has been part of the daily lives of the residents for centuries. The history of the hot spring dates back 600 years.
Legend has it that one night, the third head priest of Taineiji Temple, Joan Shuzen, was walking the temple grounds, not far from the Onto hot spring, when he came upon a man engaged in Zen meditation on a rock. Joan Shuzen asked the old man his name,and the old man answered with a Waka poem, “I am the God Sumiyoshi in the hidden place, now and of old, where the wind blows through the pines,” and his true form was revealed to be the God Sumiyoshi Daimyojin of Ichinomiya in the Province of Nagato. Joan Shuzen invited the old man into the temple, and instructed him in the Way of the Buddha. Then, in 1427, when the old man was given a brocade robe by Joan Shuzen, he said, “I have brought forth a hot spring. Please use it if you like,” to repay the kindness, and he transformed into a dragon and flew up into the sky.
That was the start of the Onto hot spring. Today, the source of the hot spring remains in the possession of Taineiji Temple, which to this day also possesses many records and cultural artifacts that back up the legend, such as a wooden statue of Sumiyoshi Daimyojin wearing a brocade robe. So what is legend and what is fact? We spoke with Keijo Iwata, the 53rd head priest of the temple, to find out..
“Taineiji Temple is a temple of the Soto School founded in 1410 by local lord Washizu Hirotada, a member of a branch of the Ouchi Clan. In those days, schools of Zen Buddhism, such as the Soto School, were strongly tied with local feudal lords, and temples were typically accompanied by hot springs as a place for priests to purify themselves during spiritual training. Meanwhile, the Ouchi Clan had amassed great riches through trade with China and Korea. Sumiyoshi Daimyojin is a god who protects travel across the sea. Given this background, it is possible that the Ouchi Clan colluded with Taineiji Temple and Sumiyoshi Shrine to construct the story for political purposes.”
Before the Onsen’s recent renovation, there was another hot spring adjacent to it called Reito which was once used only by warriors and priests, while Onto was for use by the common people. It is said that the priests said prayers of gratitude to the gods before getting into the bath. A stone statue of Sumiyoshi Daimyojin which has been passed down through the ages sits in the Onto bathhouse. Throughout, one can sense hints of why this hot spring is known as Shinju-no-yu, or A God’s Bath. “The Mori Clan came to rule over the entire Chugoku region after the fall of the Ouchi Clan. The reports on temple activities submitted by Taineiji Temple to the Mori Clan always contained an episode on the ‘hot spring gifted by the God Sumiyoshi.’ So surely Onto has been known as a sacred hot spring for many centuries.”

Architecture that embodies the legend of Shinju-no-yu

The Sumiyoshi Shrine sits atop the hill over the Onto Onsen. The renovations of the hot spring have resulted in a new scenic view created together with the Sumiyoshi Shrine and the Otozure river.

 

The Onsen is shown at the front, while the glass building on the other side of the Onto Plaza is the Onto Shoku restaurant. Both structures are single story so as not to interrupt the scenery in the hot spring resort. Visitors can also spend a leisurely moment on the long porch, called an Engawa.

 

A harmonious space formed by buildings and nature

 

The sky opens wide before you when you descend the bamboo grove stairway (Chikurin-no-Kaidan) to the green lawn of the Onto Plaza, accompanied by the soothing murmurs of the Otozure river resonating in the air. With the Onto hot spring on the left and the Onto Shoku restaurant on the right, the structures blend seamlessly into the nature around them, becoming a natural part of the landscape.
The Onto hot spring and Onto Shoku restaurant were both designed by the Shohei Oka Architectural Office. We interviewed Shohei Oka to learn more.
“The Onto hot spring waters bubble up from the bedrock covering the ground, so the conditions here are quite special. In ancient times, people likely bathed in the standing pools of water where it bubbled up from the bedrock. Accordingly, we designed baths to accept this naturally flowing water to recreate that natural approach.”
When you get into the baths, before you is the natural bedrock as it has always been, and you can watch the water flow from it. Furthermore, the Onto hot spring was built directly over the bedrock from which the water comes, so you can see that water flows into the baths from the bottom as well. As a result, here you can enjoy hot spring water of the highest purity. That water is a simple alkaline hot spring (pH 9.62). The hot spring water flows from the bedrock at 39° C, making it soft and gentle as it embraces your skin.
Also, our insistence on using only spring water direct from the source resulted in baths that match the water volume in size. We also maintained a bath depth commensurate with Onto tradition. Some records indicate that the baths were already about 1 meter deep during the Edo period.
“Also known as Shinju-no-Yu (A God’s Bath), Onto is located right next to Sumiyoshi Shrine. Accordingly, we decided that it would be best to design the buildings, so they become a part of the shrine. Thus, the Chiyobashi Bridge in front of the Onto hot spring is like the entrance to a sacred place. Passing from the door to the watch room is a stairway that leads up to Sumiyoshi Shrine. This represents a new path for worshippers visiting the shrine.”
The composition of the building places the watch room in the center, half occupied by baths and half occupied by a rest area.
“Three of the walls around the rest area are full length glass. And the dining building across from it is also an almost identical construction. The plaza, Otozure river, and dining building come together to form a single space because we extended the eaves to add a long porch, or Engawa, along the building.”
The Onto continues to serve as a symbol for the Nagato-Yumoto Hot Spring resort.

The firm is involved in community development to increase community value, such as their project to open the Busshozan Hot Spring in Takamatsu City, Kagawa Prefecture.

 

The designer of Onto also designed new guest rooms at a local inn


The Shohei Oka Architectural Office was also involved in the renewal of the Gyokusenkaku Inn, The guest rooms were designed as simple spaces in which the terraces continue naturally from the rooms. The rooms are floored with chinquapin wood grown and harvested in Nagato.

Travelling around the area

Here we introduce inn proprietors Kazuhiro Otani of Otani Sanso, and Shuichi Ito of Gyokusenkaku, both born and raised at the Nagato-Yumoto Hot Spring resort. We asked them about the appeals of Onto Onsen.


The Onto Plaza, with shaded spots, is situated between the Onto hot spring and the Onto Shoku restaurant , while the Gangi Plaza can be found by descending to the Otozure river.

–How old were you both when you first used the Onto baths?

Otani: I was in the first grade of elementary school. It really surprised me, and filled me with joy as well. The baths of Onto were so deep, my feet didn’t reach the bottom yet. Intuitively, I immediately fell in love, because, let’s face it, hot springs are fun.

Ito: For me it was the opposite. I was afraid of the Onto baths because my feet didn’t reach the bottom, and I thought I would drown. I think the first time I bathed here was when I was in nursery school. But once I entered elementary school and learned how to swim, it was no longer scary, so after playing with friends, we would head straight to the Onto baths.

Otani: The standard course was to go to the Onto baths after playing at the Otozure river.

Ito: Onto was at the center of our playground, so to speak. There was the Otozure river, the grounds of Sumiyoshi Shrine, and then of course there was the Yumoto Hot Spring Noryo Bon-odori Festival, where the Yagura stand would be erected over Chiyobashi Bridge in front of Onto, and everyone would dance along the road beside the Otozure river.

Otani: The Onto hot spring and the Otozure river are deeply intertwined, and part of the daily lives of the people who live here. There is a washing spot on the riverside, and people would wash their laundry there using water flowing from the Onto hot spring until the early 1960s. That was a social gathering place for the locals.

 

— The Onto Onsen was originally a publicly built and operated facility, but it became privately owned after the renovations. Both of you are joint proprietors of Nagato Yumori, the organization that now manages Onto. What are your thoughts on the new role of Onto?

Otani: Joining the members of Nagato Yumori are Masako Aomura, the descendant of a local samurai who was once responsible for managing the hot springs at Taineiji Temple long ago, and Shinichi Shiraishi, a graphic designer based in Nagato City. The philosophy of Nagato Yumori is to create a unique lifestyle culture that matches the lives of the citizens through the use of the public spaces in the Nagato-Yumoto area. Isn’t it an ideal lifestyle to use the hot spring baths after work, and then maybe enjoy Yakitori and beer on the riverside afterwards? Our hope is to offer just such a lifestyle, one that fits with these surroundings, with the local residents and travelers who visit here. And we believe that the Onto hot spring symbolizes that lifestyle.

Ito: We want the guests staying at the hot spring inns to also join us in this bath of culture, so to speak. You can enjoy the illumination of the Chikurin-no-kaidan (bamboo grove stairway) or Koyo-no-kaidan (autumn leaves stairway), or gaze at the Ayu sweetfish and other river fish swimming in the beautiful Otozure river on your way back and forth between the inn and Onto baths, and I think that brings the enjoyment of this hot spring resort and the trip itself to a whole new level.

Otani: A hot spring bath is a sort of utopia. Locals and visitors can interact with each other from the same position, irrespective of age or occupation. So I believe that Onto also functions as a new place to interact.

 

— So the lifestyle culture centered around Onto is itself the greatest appeal of this place, and its greatest tourism resource?

Ito: Yes, and Onto is an opportunity for us to experience hot spring as well. The perpetuation of Onto and the perpetuation of this hot spring resort are closely linked, and they must continue and grow together.

Otani: I’m sure that visitors here are enthralled by the sight of the locals enjoying their daily lives here. And when the visitors fall in love with this place, it brings pride to the locals in turn. My hope is that together, we can build an even better relationship.

Top: One can view the hot spring water bubbling up from the bedrock from the Onto baths. A stone statue of Sumiyoshi Daimyojin watches over the bathers from the back. Bottom: Lanterns are floated on the river as the head priest of Taineiji Temple reads sutras as part of the Yumoto Hot Spring Noryo Bon-odori Festival held every year in August.

Onto cuisine brings joy to your heart and body

The Onto Shoku restaurant offers a menu of healthy dishes carefully prepared with selected ingredients. The restaurant serves all manner of needs, including lunch, teatime, and dinner.

Nagato Egg-Chicken Rice. This dish is also available as a set including Marinated Seasonal Vegetables and Kuro-kashiwa (black chicken) Soup.

Rie Kawada trained as a chef in Tokyo before returning to her hometown of Nagato.

After soaking yourself in the hot spring baths of Onto, it’s time for a visit to Onto Shoku restaurant across the way. This restaurant offers a menu featuring such dishes as Choshu chicken, a local delicacy of Nagato City, and handmade tofu, and the gentle flavors that seem to permeate your body are the perfect accent to fill you after a bath.
“What I focus on is cooking in a way to bring out the natural Umami, or savory flavor, of the ingredients. I really want my guests to enjoy the flavors of Nagato ingredients, such as the flavorful and tender Choshu chicken, the thick handmade tofu, and the fresh seasonal vegetables grown and harvested locally,” says Rie Kawada, chief chef of Onto Shoku.
One of the more popular dishes on the menu, one which seems to condense the delicious flavors of Nagato into a single experience, is the Nagato Egg-Chicken Rice which features rice in a broth made from Choshu chicken steamed in liquor topped with steamed sweet and spicy Choshu chicken wings, and covered in a fluffy egg sauce made from eggs procured locally in Yamaguchi Prefecture. We also recommend that you order a side dish of Marinated Seasonal Vegetables that will give you an experience of the depth of flavor of the local produce here.
On a sunny day, you can take out your food and drink and enjoy it in the breeze along the banks of the Otozure river.
