Overview
Yokokawa Onsen Yudono Totonoyu is a small hot spring stay in the wooded hills of Shimoda, in the southern part of the Izu Peninsula. You come here for privacy, nature, and source-fed hot spring bathing rather than a busy resort atmosphere. Each room has its own hot spring bath, so you can soak in your own space while enjoying the changing scenery through the seasons.
The property focuses on quiet, independent relaxation. You have private baths, open-air bathing, selected rooms with sauna facilities, and an unmanned check-in system that keeps arrival and departure simple. The stay feels best when you want to slow down, spend time in your room, and let the forest setting shape the rhythm of your trip.
Accommodation
In the main building, you can choose from four rooms named Haru, Natsu, Aki, and Fuyu. Each room has its own character and includes a source-fed hot spring bath. The main building rooms are Japanese-style spaces with six tatami mats, and each one gives you a private bathing experience with nature close by.
Haru includes a glossy granite bath, barrel sauna, cold bath, sauna hat, and poncho. This room works well when you want to build your stay around a private sauna and hot spring cycle. After the sauna, you can cool down, soak, and rest without leaving your room area.
Natsu has a ceramic bath and a calm Japanese-style room. From the wood deck, you can look toward the mountain scenery and spend your time slowly between the room, bath, and outdoor space.
Aki has a bath finished with natural stone mosaic tiles. The room keeps the focus on tatami warmth, quiet time, and a private soak with a softer, more textured bath setting.
Fuyu includes a cypress bath, barrel sauna, cold bath, sauna hat, and poncho. The scent of cypress adds a fresh, clean feeling to the bathing space, while the private sauna lets you move between heat, cold water, and rest at your own pace.
All main building rooms include free Wi-Fi, a washlet toilet, washbasin, balcony, hair dryer, tea set, BALMUDA kettle, bath towel, face towel, toothbrush set, cotton swabs, cotton, face lotion, and milky lotion.
You can also stay in the detached annex, a completely private house surrounded by trees. It includes a spacious living-dining room, an 8-tatami Japanese-style room, and a second-floor bedroom with two Simmons double beds. The large wood deck includes a semi-open-air granite hot spring bath, sauna house, barbecue space, and pool.
The annex gives you more freedom for a longer or more private stay. The kitchen includes an IH cooktop, dishwasher, cooking tools, tableware, and basic seasonings, so you can bring ingredients and cook for yourself. The sanitary room includes a washer-dryer, and the living-dining room has a wood stove for winter stays.
Dining
Yudono Totonoyu keeps dining flexible rather than formal. If you want breakfast, the property offers self-service breakfast in a bright dining space facing the wood deck. You choose Japanese or Western breakfast when you book, then enjoy your meal while looking out toward the natural surroundings.
You can also enjoy the on-site café on Saturdays. The café has a warm wood atmosphere and serves nostalgic Japanese café dishes such as cream soda, meat sauce pasta, toast, and an Izu-style dried horse mackerel set meal. The café is open on Saturdays from 11:00 a.m. to 3:00 p.m.
Onsen and Wellness
The hot spring here is Yokokawa Onsen, an alkaline simple spring with a pH of 8.5 to 9.5. The source temperature is listed as 56.3°C, and the property presents the water as smooth, soft, and gentle on the skin. The listed benefits include support for rheumatism, stiff shoulders, lower back pain, joint pain, sensitivity to cold, fatigue recovery, and skin-beautifying effects.
The main appeal is that you can enjoy source-fed hot spring water in your own private space. In the main building, each room has its own bath, while the annex includes a semi-open-air granite bath on the wood deck. This means your onsen time stays personal, quiet, and easy to repeat throughout your stay.
If you choose Haru or Fuyu, you also have a barrel sauna and cold bath. If you stay in the annex, you can use a private sauna house and a Goemon-style cold bath, then rest outside in the natural air. This makes the property especially appealing when you want to combine hot spring bathing with sauna time in a private setting.
Guests with Tattoos
Because you can soak in a private bath inside your room, you will be able to enjoy the onsen regardless of tattoos.
Facilities
Yudono Totonoyu has four main building rooms with private source-fed hot spring baths, plus a detached annex with a semi-open-air granite bath, sauna house, pool, barbecue space, kitchen, living-dining room, Japanese-style room, and second-floor bedroom. In selected main building rooms, you also have a barrel sauna, cold bath, sauna hat, and poncho.
The property also offers free Wi-Fi in the rooms, washlet toilets, balconies, hair dryers, tea sets, BALMUDA kettles, towels, toothbrush sets, cotton items, face lotion, and milky lotion. The annex adds a fuller private-stay setup with a kitchen, IH cooktop, dishwasher, cooking tools, tableware, basic seasonings, washer-dryer, wood stove, Weber grill, and natural hot spring pool that can be used beyond summer when reserved.
Activities
Your main activity here is simple: soak, rest, use the sauna if your room includes one, and spend quiet time surrounded by the wooded landscape. The property suits a slow stay where you move between your room, bath, deck, and rest space without rushing.
If you want to explore, the official area guide lists Shimoda Aquarium, Shirahama Ohama Beach, Dogashima Tensodo Cave, Izu Granpal Park, Mount Omuro, and Perry Road as nearby sightseeing ideas. You can spend the day by the sea or in town, then return to your own hot spring bath in the evening.
Additional Features
Yudono Totonoyu uses an unmanned check-in system, so check-in and check-out stay smooth and simple. Check-in starts at 4:00 p.m. Check-out is 10:00 a.m. for Natsu and Aki, and 11:00 a.m. for Haru, Fuyu, and the annex.
This property works best when you want a private hot spring stay with minimal fuss. You can choose a compact Japanese-style room with its own bath, select a sauna room for a deeper wellness focus, or book the annex for more space, a kitchen, a barbecue area, a sauna house, and a pool. The experience stays centered on source-fed onsen water, quiet surroundings, and time you can shape for yourself.
