Overview

Akazawa Onsen Hotel gives you a wide Pacific Ocean view from a hillside setting in Izu. You stay in the Akazawa Onsenkyo resort area, where sea, forest, hot springs, spa facilities, and leisure spaces come together in one coastal escape. From the moment you arrive, the open view of Sagami Bay sets the tone for a stay built around bathing, good food, and time by the sea.

The hotel was renewed with rooms and a lobby design inspired by the sea and forest of Izu. You can spend your stay soaking in natural hot spring water, relaxing in an ocean-view room, enjoying Japanese kaiseki dining, or moving between the wider resort facilities. This is a good choice when you want more than a quiet room: you have hot springs, spa time, bowling, play spaces, lounge areas, and the coast all close at hand.

Accommodation

Akazawa Onsen Hotel offers all-ocean-view rooms, so you can look out toward Sagami Bay from your own space. The rooms feel generous, easy to settle into, and well suited to a coastal break, whether you prefer a Japanese room, a Western room, a Japanese-Western layout, or a room with your own open-air bath.

The Standard Rooms measure 39 square meters and come in Japanese, Western, and Japanese-Western styles. These rooms keep the stay simple and comfortable while still giving you a full ocean view from the window. They work well when you want the scenery and hot spring access without choosing a larger room.

The Corner Twin Room measures 62 square meters and gives you a more open stay with two-sided natural light. You have a separate bedroom and living-dining area, plus a balcony where you can enjoy the Pacific view. This room suits you well when you want more space to relax indoors between baths and meals.

The Deluxe Room measures 62 square meters and combines a bedroom with a Japanese room. Large windows frame the view of Sagami Bay, and the two-room layout gives you room to stretch out, talk, rest, and enjoy the slower rhythm of Izu.

The Open-Air Bath Room measures 39 square meters and gives you a private open-air bath in your own space. You can enjoy the garden-like setting with dry landscape details, earthen walls, and a deck area where you can cool down after bathing. This room is the best fit when you want a more private hot spring-style stay.

Rooms include towels, bath towels, yukata, slippers, shampoo, conditioner, body soap, hand soap, cleansing oil, skincare lotion, milky lotion, toothbrush set, hairbrush, razor, cotton set, hair tie, and free Wi-Fi.

Dining

Dinner at Akazawa Onsen Hotel focuses on Japanese kaiseki cuisine made with seasonal ingredients and fresh seafood from the waters around Izu. The meal is served at Restaurant Kira on the 4th floor, where you can enjoy a calm dining setting after a day of hot springs, spa time, or sightseeing.

The dinner style highlights the natural flavor of local seafood and seasonal produce rather than heavy presentation. You can enjoy a meal that feels connected to the coast, with carefully prepared courses that bring out the freshness of the region. Dinner is served from 17:00 to 21:00.

Breakfast is a Japanese and Western buffet served from 7:00 to 10:00, with final entry at 9:30. You can start the morning with a relaxed meal before returning to the bath, heading out along the coast, or taking the shuttle to Izu-Kogen Station.

Onsen and Wellness

The hot spring experience is one of the main reasons to stay at Akazawa Onsen Hotel. The hotel’s large bath uses natural hot spring water from a 54°C source and gives you a sweeping ocean-view bathing experience. You can soak in the morning light, return in the evening after dinner, or enjoy a late bath before bed.

The hotel bath is open from 5:00 to 11:00 and again from 15:00 to 25:00. The wide hours make it easy to fit bathing into your own schedule, whether you want a quiet early-morning soak or a slow night bath.

For a more private experience, you can reserve Tenkyu no Yu, the rooftop open-air private bath. This bath looks out toward the sky and sea, giving you a more open and personal way to enjoy the hot spring. It is available by same-day reservation for one-hour use, with hours from 7:00 to 11:00 and 15:00 to 22:00.

You can also use Akazawa Day-Trip Onsen Hall as part of the resort experience. Its large open-air bath is designed to feel connected to the horizon, with the Pacific Ocean stretching out in front of you. Inside, you can also enjoy indoor baths, a jacuzzi, lie-down bath, and two types of sauna. Akazawa Spa adds a different kind of wellness experience, with a thalassotherapy pool using seawater drawn from 800 meters below the sea off Akazawa, plus spa and relaxation options.

Guests with Tattoos

Akazawa Onsen Hotel does not allow you to use the large public bath if you have tattoos, tattoo stickers, or body paint, unless the tattoos can be fully covered with the property’s designated cover seals. The cover seals measure 11 cm by 20 cm, and you can use up to two. If your tattoos cannot be fully covered, you cannot use the large public bath. You also cannot enter Akazawa Day-Trip Onsen Hall with tattoos unless they meet the cover-seal rule. For more privacy, choose an Open-Air Bath Room or reserve the rooftop private bath.

Facilities

Akazawa Onsen Hotel gives you a resort-style stay without making the experience feel crowded. After a bath, you can move easily between the hotel’s ocean-view spaces, private mahjong rooms, karaoke rooms, and quiet areas for relaxing. The hotel also gives you access to wider Akazawa Onsenkyo facilities, including Akazawa Day-Trip Onsen Hall, Akazawa Spa, Deep Sea Lounge, Akazawa Bowl, and Pleasure Arena.

The wider resort is especially useful when you want both rest and activity in the same stay. You can spend the morning in the hot spring, enjoy spa time in the afternoon, play a game of bowling, or relax in Deep Sea Lounge with billiards, darts, table tennis, board games, and drinks. Families can also enjoy Pleasure Arena, a large indoor play space with air athletics, slides, trampolines, and a café area.

The hotel also includes free Wi-Fi, free parking, a shuttle connection from Izu-Kogen Station, and moving carts that help you get around the resort area more easily. These touches make the stay feel smooth, especially if you plan to use several facilities during your visit.

Activities

Akazawa Onsen Hotel works well when you want a mix of hot springs, leisure, and coastal scenery. You can stay close to the hotel and enjoy the large baths, rooftop private bath, spa, bowling, karaoke, mahjong, and lounge spaces. You can also use the resort’s guest benefits before check-in and after check-out, giving you more time to enjoy the facilities around your stay.

For a more active day, Pleasure Arena gives you an indoor option that works even when the weather changes. You can also visit Deep Sea Lounge for a more relaxed indoor activity space with games and drinks. If you prefer wellness, Akazawa Spa offers thalassotherapy-style bathing and treatments using deep seawater from off the Akazawa coast.

The location also makes it easy to explore the Izu-Kogen area. You can use the free shuttle between Izu-Kogen Station and the resort, or travel by car to coastal viewpoints, museums, cafés, and nature spots around Izu.
