Located along the coast of Izu Kogen, Pleasure Resort Izu Akazawa Onsen spans a vast 25 square meter site. Offering a variety of experiences including hot springs, spas, glamping, and activity facilities, this resort has undergone a major renovation in recent years, evolving into a new type of "stay-type resort."

In April 2026, GRAX EARTH FIELD, one of the largest glamping facilities in the Kanto region, and PLEASURE ARENA, an all-weather amusement facility, will open. This large-scale complex resort is attracting attention as it offers a variety of ways to spend your time, from quiet wellness stays for adults to activity-filled stays for families.

The facility is operated by the Kato Pleasure Group, known for its traditional Japanese restaurants and restaurants such as "Tsurutontan." The group, which operates leisure and resort businesses throughout Japan, including Kyoto's Rurikei Onsen and Nagasaki's "i+Land nagasaki," has created a world that blends "fun" and "relaxation," and this is a world that breathes life into this facility as well.

The Akazawa Guest House is a lodging facility where you can enjoy the most peaceful and refined time.

Akazawa Geihinkan, which opened in 2009, underwent renovations in 2025. While retaining its beautiful sukiya-style architecture, it was upgraded to a more comfortable accommodation.

The most distinctive feature of Akazawa Geihinkan is that, despite its approximately 3,500-tsubo (approx. 11,500 square meters) grounds, it limits the number of guest rooms to just 15.

While luxury hotels have been moving towards larger sizes in recent years, the State Guest House is taking the opposite approach. Instead of maximizing occupancy rates, it values ​​"tranquility" itself.

Upon entering the lobby, you'll be immediately overwhelmed by the beautiful Japanese sukiya-style building and the vast Japanese garden. The use of lacquer and Nishijin-ori textiles throughout the building creates a comforting atmosphere that evokes traditional Japanese culture. A central courtyard surrounds the building, and walking along the surrounding corridors allows you to experience nature and the changing seasons. Furthermore, the facilities are subtly dispersed throughout the building to prevent excessive interaction between guests, resulting in extremely few opportunities to encounter other guests during your stay.

Even the standard guest rooms are approximately 70 square meters. All rooms are equipped with open-air baths using deep-sea water, and the "detached special rooms" also have saunas.

Within the Akazawa Pleasure Area, the Guest House stands out for its particularly striking "Japanese tranquility." There is plenty of open space inside, and time seems to flow slowly. Whether you're reading, gazing at the garden, or soaking in the bath, it exists not so much as a place to "do" something, but as a place to "be at peace."

Deep-sea water guides you to mental and physical wellness.

One of the essential aspects of Pleasure Resort Izu Akazawa Onsen is the wellness experience that utilizes "deep-sea water."

The facility has a dedicated deep-sea water plant on its premises, and deep-sea water, drawn from a depth of approximately 800 meters, is used in various aspects of the building.
Deep-sea water, nurtured over many years in the depths of the ocean where sunlight cannot reach, is characterized by its excellent mineral balance and gentle feel on the skin. It is also expected to warm the body from the core and have moisturizing and relaxing effects.

Only at Akazawa Geihinkan can you experience the blessings of deep-sea water in every aspect, from the open-air baths in your room and the public baths to the cuisine and drinking water.
A unique feature of this hotel is that it uses deep-sea water at different concentrations: 5% in the guest room baths and 3% in the public baths, allowing guests to enjoy different bathing experiences in each setting.

By connecting all experiences—drinking, eating, and soaking—with deep-sea water, the entire stay is designed as a wellness experience.

Dishes that utilize local ingredients and are good for your body.

The food is also one of the major attractions of this inn.

The dining area consists entirely of private rooms. Guests can enjoy their meals in peace and quiet, without worrying about their surroundings, while overlooking the courtyard.

The cuisine here focuses on seafood from the waters off Izu and local vegetables, prioritizing the natural flavors of the ingredients over flashiness, resulting in a very gentle taste. In Japanese cuisine, the meticulous work of the chefs is what creates the flavor, and this cuisine is the epitome of that. This thoughtfulness can be felt not only in dinner but also in breakfast. It is truly a very satisfying meal.

"Akazawa Spa" and "DEEP SEA LOUNGE" to enrich your stay.

Adding to the enjoyment of your stay at the State Guest House is the adjacent "Akazawa Spa," which uses deep-sea water rich in marine minerals. It boasts a variety of bathing facilities, including an open-air bath, indoor bath, reclining bath, jacuzzi, mist sauna, dry sauna, cold bath, and private sauna.
Deep-sea water, an ancient form of water, works on cells, leading to improved skin and reduced swelling. This facility specializes in harmonizing mind and body through marine therapy. Furthermore, it offers a wide range of treatments and relaxation menus, functioning as a wellness space to allow guests to experience the tranquil atmosphere of the State Guest House more deeply.
Swimsuits are required for all activities, but you can rent them at the facility, so there's no need to worry.

Furthermore, the facility located further inside, "DEEP SEA LOUNGE," is like a playground for adults.

The facility offers amenities such as billiards, and guests can enjoy free drinks and alcohol. It's a space where you can relax and forget about time, whether you're enjoying a drink after a hot bath or chatting with friends.

Furthermore, "Akazawa Bowl" is a popular spot among locals. The way local life and tourism blend together naturally is another unique charm of this resort.

A vast pleasure resort that can be enjoyed by three generations.

Let me also introduce the vast pleasure resort, Izu Akazawa Onsen. It is composed of four main areas.

And the fourth is the one that has the "Akazawa Onsen Hotel" and the "Day Trip Hot Spring Facility"ONSEN AREA(Hot spring area). I hear that the day-trip hot spring is highly regarded for its spectacular views, but the spacious relaxation area within the facility is also very appealing. The numerous private booths make it a space where you'll want to spend the whole day relaxing.

The vast grounds can be accessed by cart or shuttle bus, making it easy to explore each area at a leisurely pace. The resort is designed so that guests can freely enjoy the entire complex while choosing the style of stay that suits them best.

For example, grandparents could spend their time quietly at the guesthouse while the children's families stay in glamping accommodations. During the day, they could meet up in the lounge or pleasure arena, making a three-generation stay a natural and harmonious experience.
Even with different accommodation preferences, everyone can enjoy a comfortable stay within this single resort. This high degree of freedom is a major attraction of this place.

The appeal of Pleasure Resort Izu Akazawa Onsen lies in the fact that you can experience both "enjoyment" and "relaxation"—seemingly contradictory aspects of a stay—all in one place.
Among them, Akazawa Geihinkan is a special space where you can experience "quiet luxury for adults."

This new resort, which has opened in the Izu region, is definitely worth a visit.
