Overview
Nishiizu Koyoi brings you to Heda on the west coast of Izu, where Suruga Bay, sunset views, and local seafood shape the stay. From the 4th-floor lobby lounge, the sea opens in front of you, and in clear weather the sunset over the bay becomes one of the main reasons to arrive early and settle in before dinner.
This ryokan keeps the experience close to the character of Heda. You stay in an all-Japanese-room property with ocean views from every room, dine on creative kaiseki built around Suruga Bay seafood and local deep-sea flavors, and bathe in Toda Onsen, the newest hot spring source in Izu. It suits you well when you want a coastal ryokan with a strong sunset setting, a relaxed Japanese atmosphere, and easy access to the beach and nearby nature spots.
Accommodation
Nishiizu Koyoi has 25 Japanese-style rooms, and every room looks toward Suruga Bay. The interiors focus on a calm Japanese look, with tatami flooring, low seating, wood details, and wide windows that bring the sea into the room. The rooms are non-smoking, and the in-room baths are not hot spring baths.
The Special Room with Open-Air Bath gives you a Japanese-style room with a terrace and an ocean-view open-air bath. The room uses tamo wood in details such as pillars, lintels, and fittings, giving the space a warmer traditional feel. The bath sits outside on the terrace, so you can enjoy the sea breeze and the view of Suruga Bay from your own room, though the water is not hot spring water.
The View Bath Room gives you a Japanese-style room with an ocean-view bathtub and shower. This room type is especially appealing when you want to bathe while looking toward the sea and sunset, but still prefer to stay indoors. The design uses curved sukiya-style lines and a refined Japanese dining-house atmosphere.
The large Japanese-style rooms with an adjoining room give you more space, with a main tatami room, a second tatami room, and a wide veranda area. These rooms work well when you want extra room to stretch out, travel with family, or spend more time relaxing indoors. The standard Japanese-style rooms offer a simpler ryokan stay, with tatami flooring, futon bedding, and views of Suruga Bay.
Standard room equipment includes a TV, electric kettle, hair dryer, air purifier, and empty refrigerator where you can store your own drinks or chilled items. Amenities include shampoo, rinse, toothbrush, face towel, bath towel, bath mat, and a care set with items such as lotion and hair products.
Dining
Dinner at Nishiizu Koyoi focuses on local ingredients from Heda and Suruga Bay. The meal is a creative Japanese kaiseki served in Koyoi Dining, with seafood, seasonal ingredients, and deep-sea flavors that reflect this part of Izu. Heda is known for deep-sea seafood, and the dinner experience gives you a clear taste of the area rather than a standard ryokan meal that could be served anywhere.
Fresh sashimi from Izu’s waters forms an important part of the meal, while the rest of the course may include cooked seafood, seasonal vegetables, grilled dishes, and carefully prepared small plates. Takaashi-gani, the Japanese spider crab strongly connected with Heda, may be available as an extra dish depending on the day’s catch. Additional dishes can also include simmered golden-eye snapper, abalone prepared as sashimi or on a ceramic grill, and Ise lobster prepared as sashimi, grilled in the shell, or tempura, depending on availability and advance arrangement.
Breakfast is also served in Koyoi Dining and follows a Japanese style with plenty of Izu flavor. The deep-sea fish hot pot is one of the signature morning dishes, with a rich broth that warms you before a day by the coast. Breakfast feels generous and local, rather than light or minimal.
Dinner usually starts in the early evening, and breakfast is offered in two morning seatings. Allergy requests should be shared in advance, and changes for disliked ingredients may not always be available.
Onsen and Wellness
Nishiizu Koyoi uses Toda Onsen, which emerged in 1986 and is known as the newest hot spring source in Izu. You can bathe in the shared indoor large bath and shared open-air bath, with separate bathing areas for men and women. The baths do not switch between men and women, and there is no private bath.
The open-air bath uses a hinoki cypress tub and gives you a quiet outdoor soak in soft Toda Onsen water. The indoor bath gives you a larger bathing space where you can sit back and warm your body more fully. The shared baths do not have open sea views, so the experience centers more on the feel of the water and the quiet bath atmosphere than on scenery from the tub.
The spring quality is sodium-calcium sulfate spring water. The water is associated with support for neuralgia, muscle pain, joint pain, frozen shoulder, motor paralysis, cold sensitivity, dry skin, cuts, burns, and fatigue. Bathing hours are from 15:00 to 24:00 and again from 6:00 to 9:30.
Bath amenities include shampoo, conditioner, body soap, lotion, milky lotion, cleansing products, hair dryers, razors, and hair ties for women. Since the room baths are not hot spring baths, the shared public baths are the place to enjoy the natural onsen water.
Guests with Tattoos
Nishiizu Koyoi has shared indoor and open-air hot spring baths and does not have private baths. Tattoos must be fully covered before using the shared bathing areas. If your tattoo cannot be covered, the shared baths cannot be used.
Facilities
The 4th-floor lobby lounge is one of the main spaces at Nishiizu Koyoi. You can sit with a view of Suruga Bay in the morning or return around sunset for drinks while the sky changes over the water. Coffee and tea are available in the lounge during set hours, and original wine or original soda water is served around sunset time depending on the day and conditions.
The property also has a small shop on the 4th floor, where you can find local items such as Heda salt, salt yokan, tachibana chili pepper, snacks, canned drinks, and the chef’s handmade chirimen-jako. There is no alcohol vending machine inside the building, so drinks such as canned beer and canned chuhai are handled through the shop.
The cigar room is the only smoking space inside the ryokan and is available at any time. Karaoke is available by reservation, and outside drinks may be brought into the karaoke room. A table tennis room is also available on a first-come basis, making it an easy after-bath activity before or after dinner. Parking is available on site, with covered space for motorcycles on a first-come basis.
Activities
Nishiizu Koyoi has a private path down toward the sea, and you can walk to Mihama Beach in about five minutes. The beach sits inside a calm bay, making it one of Heda’s main seaside spots. The ryokan also gives you easy access to short walks and viewpoints around the area.
Morokuchi Shrine sits at the tip of Mihama Cape and is known for its red torii gate, its connection to seafaring and fishing, and its view toward Mount Fuji on clear days. It is close enough for a relaxed walk from the ryokan. Kenko no Mori is another nearby walking area, set on higher ground above the cape, with forest paths, birdwatching, and views over Mihama Cape and Mount Fuji when the weather is clear.
Midori no Oka is a scenic viewpoint on the way toward Heda, with views over Suruga Bay, Toi, and Dogashima on clear days. Mihama Beach is also a good choice in summer, with calm water inside the bay and seasonal seaside activity. If you prefer a simple stay, spend the afternoon in the lounge, walk to the beach before dinner, then return for the onsen and kaiseki.
