Tokyo, Japan

Aman Spa Tokyo occupies the top two floors — the 33rd and 34th — of the Otemachi Tower in central Chiyoda Ward, making it Aman's first urban sanctuary and, at nearly 2,500 square meters, one of the largest hotel spas in the city. The space is designed as a deliberate antidote to the energy of Tokyo below: minimalist Japanese wood paneling, floor-to-ceiling windows framing skyline views, eight treatment rooms, onsen-style hot baths, steam rooms, a state-of-the-art fitness center with TRX equipment, dedicated yoga and Pilates studios, and a striking 30-meter black basalt indoor pool. Every treatment opens with a complimentary foot ritual using white cobblestones, meant to ground the body and enhance the sensations of the session that follows. The treatment philosophy draws on the Japanese understanding of nature and the seasons, using natural ingredients across its menu of massages, facials and body journeys — a blend of Japanese, Chinese and Western technique. Signature offerings include the 150-minute Aman Tokyo Signature Journey, combining a camphor scrub, kuromoji powder and Japanese clay with a 90-minute rubdown drawing on both Shiatsu and Western massage; the Kuromoji Tea Journey, built around a body wrap with kuromoji clay followed by a stress-relieving massage using the hotel's own signature kuromoji oil; and the traditional Shinto water ritual known as the Misogi Experience, designed to purify the body and reset the mind. A rotating "Seasonal Journey" treatment aims to rebalance body, mind and spirit in step with the changing seasons, in keeping with the spa's broader nature-and-balance philosophy. Beyond individual treatments, the spa offers structured wellness experiences like Evening Yoga and Meditation, a private high-rise session blending light movement, meditation and breathwork for evening relaxation, alongside access to the fitness center and studios for guests wanting a more active stay. Facilities are available to all hotel guests, and non-staying visitors can also book access through packages like the one-day Aman Wellness Program. Guests can extend the experience home through Aman Skincare and Aman Fine Fragrance, both sold on-site and built around natural, ancient-tradition-inspired formulas that let visitors continue the spa's holistic approach after checkout.

Hyogo, Japan

THE PASONA natureverse retreat opened on Awaji Island in Hyogo Prefecture on June 23, 2026, overlooking Osaka Bay and designed by Pritzker Prize-winning architect Shigeru Ban, known for his use of natural and recycled materials. Unlike most wellness hotels built around short weekend resets, the retreat is purpose-built for long-stay wellness, opening its first phase of 11 rooms and centering its philosophy on Mibyo — the Japanese concept that wellness isn't merely the absence of illness but an ongoing state continuously shaped by lifestyle and state of mind. Stays require a minimum of three nights, though the retreat's core proposition is aimed at guests seeking genuinely extended, preventive-care immersion. Wellness programming is built around three pillars — nutrition, exercise and sleep — supported by a clinic-backed personal program developed in collaboration with Kobe University Hospital, giving guests access to on-site medical support and monitoring throughout their stay. Guests can access thalassotherapy, personalized physical conditioning, yoga and zen meditation, including aerial Zen sessions, with movement classes designed to ease muscle tension alongside more contemplative practices. Sleep receives particular emphasis: guest rooms feature sensor-integrated beds co-developed with NITORI and MinebeaMitsumi, built on "Future Sleep" technology first showcased at Expo 2025 Osaka, which automatically adjusts sleep posture by detecting body movement through the night. All rooms also include private onsen baths fed by mineral-rich hot spring water drawn directly from the ground below. Dining plays a central role in the wellness concept, with Michelin-starred chefs preparing wellness gastronomy built on seasonal, locally sourced Awaji Island ingredients, tying the retreat's culinary offering directly to the island's culinary tradition. Beyond treatments and cuisine, the retreat layers in rich cultural programming — performances by Pasona Group's own Music Island Project, PASONA Awaji World Ballet, PASONA Awaji Opera Company, and the taiko drum ensemble Kotan — alongside farming activities that connect guests hands-on with the island's natural environment. Comprehensive hospitality services, including housekeeping and chauffeur assistance, are built in to support comfortable, extended stays, reinforcing the retreat's positioning as a fuller, technology-integrated approach to long-term health and longevity rather than a brief indulgent getaway.

Oita, Japan

Kamenoi Bessou opened in 1921 as a private villa for VIPs of Kumahachi Aburaya, considered the father of tourism in nearby Beppu, and sits on a 10,000-tsubo property in the Yufuin Valley at the foot of Mount Yufu, a dormant volcano whose mineral-rich runoff feeds some of the highest hot spring output in Japan. The ryokan's wellness identity is inseparable from this natural onsen source: free-flowing, naturally heated spring water fills every bath on the property, from the large public bath — open to the fragrance of surrounding greenery and starlit skies through the night — to the private baths built into many of the individual guest cottages. Set on the shores of Kinrin Lake amid trees more than 200 years old, the grounds themselves are treated as part of the restorative experience, with a garden designed for slow afternoon strolls. Accommodation is split between 11 to 14 detached cottage-style rooms (hanare) scattered through the forested grounds and six Western-style rooms in the main building, many of the cottages featuring their own open-air private onsen bath fed by the same natural source. The onsen water itself is classified as a simple hot spring with documented therapeutic properties for neuralgia, muscle and joint pain, frozen shoulder, poor circulation, chronic digestive issues and general fatigue recovery — reflecting the traditional Japanese understanding of bathing as functional therapy rather than purely relaxation. The large public bath operates nearly around the clock, closing only briefly overnight for the changeover between men's and women's hours. Beyond the baths, wellness at Kamenoi Bessou extends into the ryokan's broader sensory and culinary rhythm: seasonal kaiseki cuisine built from local Oita and Yufuin ingredients — wild vegetables, river fish, regional meats — served either in-room for cottage guests or at the on-site restaurant, Hotarubi-en, for those in the main building. The garden's teahouse, Tenjō Sajiki, transforms into a bar, BAR Yamaneko, in the evenings, giving guests a quiet space for a nightcap after bathing, while a lounge with a working gramophone and coffee service adds a further layer of unhurried, old-world calm to the overall stay.

Kyoto, Japan

Six Senses Kyoto, opened in 2024 in the historic Higashiyama district and drawing design inspiration from the Heian period when Kyoto served as Japan's imperial capital, built its wellness identity around a blend of Zen tradition and modern science. Sleep support runs through the entire property, starting with the rooms themselves: every one of the 81 guest rooms and suites follows the brand's Sleep With Six Senses philosophy, featuring bespoke organic mattresses, temperature-regulating pillows and duvets, and organic cotton sheets, with many rooms overlooking either Toyokuni Shrine or a private inner courtyard Zen garden. For guests wanting to go further, personalized sleep consultations combine data from a sleep tracker with guided yoga nidra, meditation, relaxing treatments, nutrition advice and low-intensity training. The Six Senses Spa itself spans four treatment suites — a double suite named Smell and three single suites named Sound, Sight and Taste — alongside a multi-purpose Sensory Studio used for meditation, yoga and even flying yoga, an indoor swimming pool, a traditional Japanese bathhouse, sauna, steam facilities and cold plunge. A standout, Kyoto-exclusive offering is the Ah-un treatment, which uses ritual and sound therapy to guide guests toward what the brand describes as inner peace, balance and awakening in Zen. For recovery-focused guests, a Biohack Recovery Lounge offers compression boot and compression belt sessions designed to ease muscle soreness and fatigue after long days exploring the city. Structured wellness programming runs from half a day up to six days, organized around four core focuses: Sleep, Detox, Yoga and Fitness, each opening with a non-invasive Wellness Screening that measures inner health, movement and sleep patterns to personalize the treatments, activities and nutritional guidance that follow. The dedicated Sleep Program, for instance, combines a wellness screening, yoga nidra or pranayama sessions, a signature 90-minute Dreamcatcher treatment, daily sleep tracking, biohacking recovery sessions and a calming, sleep-enhancing dinner menu at the hotel's restaurant, Sekki. The property has continued to expand its programming with maternity-focused offerings — including Pregnancy Watsu treatments in Kyoto's only dedicated Watsu pool — family wellness experiences for younger guests, and monthly Full Moon Night Gatherings, reflecting a broader push to make its wellness offering relevant across different life stages and guest needs.

Tokyo, Japan

Janu Tokyo, the debut property of Aman Group's new Janu brand, sits in the newly developed Azabudai Hills neighborhood and is anchored by a 4,000-square-metre, four-storey wellness centre — one of the largest in the city. Janu, meaning "soul" in Sanskrit, is explicitly built around a philosophy of social wellness, and the wellness centre reflects that with two distinct zones: one geared toward active, communal movement and one toward slower, more traditional relaxation. The fitness side includes one of Tokyo's largest hotel gyms at 340 square metres, equipped with Technogym, Outrace and SkillX machinery, alongside five dedicated movement studios offering spinning, yoga, aerial yoga, a golf simulator, and the first boxing ring in a Tokyo hotel — plus a recovery studio featuring a hyperbaric oxygen therapy chamber. The relaxation side centers on an extensive hydrotherapy and thermal area, anchored by a striking 25-metre lap pool and a separate heated lounge pool surrounded by loungers designed for social unwinding. Traditional Japanese bathing facilities, cold plunge pools, saunas and steam rooms are built into both the male and female changing areas, along with a separate family changing room. Two signature Spa Houses — the first of their kind in Tokyo — are available for exclusive private hire by up to four guests, each featuring hot and cold plunge pools, relaxation rooms, double treatment rooms, and traditional banya and hammam facilities blending Eastern European and Middle Eastern bathing ritual with Japanese sensibility. The spa's treatment menu spans seven treatment rooms, with the 90-minute Janu Signature Massage standing out as the property's flagship offering. For guests not staying overnight, Janu Tokyo has opened its wellness centre to day visitors through Spa House Day Experiences — personalized two-to-four-hour journeys built around a traditional banya, hammam, or Janu signature treatment. A dedicated consultation room and hair and nail salon round out the more clinical and beauty-focused side of the offering, while the broader wellness centre's emphasis on group classes, from high-impact circuit training to social spinning sessions, reinforces Janu's positioning of wellness as a communal, connection-driven experience rather than a purely solitary pursuit.

Hiroshima, Japan

Azumi Setoda occupies a 140-year-old former merchant estate on Ikuchijima, a small citrus-growing island in the Seto Inland Sea, co-founded by Naru Developments and Adrian Zecha — the hotelier behind Aman Resorts — as the first property in his Azumi line. Kyoto architect Shiro Miura restored the 22-room compound, once home to the influential Horiuchi family, to balance traditional materials like washi paper, shikkui plaster and local granite with a minimal, contemporary sensibility. Wellness here is woven quietly into the architecture itself: every guest room has its own deep hinoki cypress wooden bathtub with a secluded outdoor view, making private bathing a built-in part of the stay rather than a separate spa visit. Beyond the in-room baths, guests can cross the street to the ryokan's yubune bathhouse for a traditional Japanese-style onsen hot spring soak, complete with a sauna, or make use of the on-site spa for massages, facial and body treatments and other beauty services. Mornings open with a private, early Ashtanga Yoga lesson at the Azumaya Pavilion, incorporating breathwork, gaze practice and asanas across a structured sequence — a quiet, personal complement to the ryokan's broader hot-bath culture. The overall approach favors slow, sensory restoration over a packaged program: minimalist rooms, natural materials and unhurried pacing are themselves treated as wellness elements. Wellness at Azumi Setoda also extends outward into the island's culture and landscape. Guests can join natural farming lessons, cycle the Inland Sea's coastal roads on rental bikes, sail by catamaran, or take part in traditional Japanese tea ceremonies, tying physical movement and cultural practice into the same restorative rhythm as the baths and yoga. Dining reinforces this local, grounded philosophy as well — meals draw on ingredients sourced from nearby farmers and fishers, served on dishware once used by the Horiuchi family, so that even the culinary experience carries forward the estate's history and sense of place.

Ago Bay, Japan

The Hiramatsu Hotels & Resorts Kashikojima is an intimate, eight-room retreat set within Ise-Shima National Park on the shores of Ago Bay — one of Japan's noted natural treasures — built around a "western ryokan" concept that blends Western architectural style with traditionally Japanese, thoughtful rural hospitality. Recognized with a Michelin Key distinction for its unique personality and elevated guest experience, the property is small by design, giving wellness offerings here a highly personal, unhurried quality rather than a large resort-style facility. At the heart of the wellness offering is the Okushima Hamashima Onsen, a natural hot spring available in guest rooms in the Annex as well as private open-air baths, letting many guests soak in mineral-rich spring water without leaving their room. The spa itself features a thalasso pool filled with real seawater drawn from the seas around Kashikojima, alongside signature Clayd Spa treatments built around a mineral-rich clay sourced from the deserts of the US West Coast. Every spa treatment at the property includes a Clayd clay pack, using 100% organic clay, essences and essential oils to help release toxins and restore the body; the signature Clayd Ritual runs a full 180 minutes, alongside standalone 90- and 120-minute body massage options. Beyond the spa and onsen, wellness at Hiramatsu Kashikojima is closely tied to the resort's broader culinary identity — the on-site restaurant blends French culinary tradition with the finest seasonal ingredients of the Shima region, an area historically renowned in Japan as a miketsu-kuni, a province that once sent food offerings to the Imperial court. This pairing of refined French dining with therapeutic hot-spring bathing and clay-based spa ritual gives the resort a distinctly restorative, sensory-led approach to wellness, reinforced by the natural beauty of Ago Bay itself and easy access to the adjacent golf course and nearby Jiro-Rokuro Beach for guests wanting a gentler, more contemplative form of relaxation outdoors.

Yakushiyama, Japan

Beniya Mukayu sits on the slopes of Yakushiyama, known as "Healing Buddha Mountain," in Yamashiro Onsen in Japan's Ishikawa Prefecture — a site that was once home to Yakuoin Temple, where monks are said to have cared for travelers through hot spring bathing and medicinal herbs. The ryokan carries that legacy forward directly: all 16 guest rooms face the property's Forest Garden and include a private open-air onsen bath, turning bathing into a personal, any-hour ritual rather than a scheduled spa visit. The property draws its name from the Zen concept of Mukayu — richness found in emptiness — and its minimalist design, built from tatami matting, washi paper, bamboo and diatomaceous earth, reflects that same philosophy of restraint and stillness. Beyond the private in-room baths, guests can use two communal onsen — named Gensei and Usuko — separated by gender on a rotating schedule, and Spa Entei, the ryokan's dedicated treatment institute, which draws on Yamashiro's mineral-rich hot spring water (with a history spanning more than 1,300 years) and locally sourced medicinal herbs from Mt. Hakusan. Signature offerings include the Yakushiyama Treatment, built around onsen water and herbal remedies in direct homage to the mountain's healing history, alongside hot stone massages and herbal body scrubs. Guests can also join a hands-on Medicinal Herbal Ball Making experience with Spa Entei's therapists, selecting wild seasonal herbs, wrapping them in cotton cloth and steaming them in hot spring water to create their own take-home wellness ritual. Wellness at Beniya Mukayu extends into quieter, culturally rooted rituals as well: an afternoon tea ceremony hosted personally by the ryokan's owner in one of three on-site libraries, embodying the Japanese hospitality concept of omotenashi and the idea that every encounter is unrepeatable; and a guided flower appreciation and arrangement session in the property's gardens, rooted in the same tea-ceremony aesthetic. For guests wanting a more structured stay, the ryokan offers a dedicated "Yakushiyama Wellness Retreat" package weaving these elements — onsen bathing, herbal spa treatment, tea ceremony and quiet reflection — into a single multi-day experience, alongside kaiseki dinners built around seasonal ingredients gathered from Kaga's mountains, rivers, lakes and coastline.

Ise-Shima, Japan

Amanemu sits against the forested hills of Ise-Shima National Park in Japan's Mie Prefecture, overlooking Ago Bay, and every accommodation — whether suite or villa — features its own private onsen bath and wooden decked terrace, extending the resort's hot-spring identity into the rooms themselves. At the center of the property is the 2,000-square-meter Aman Spa, built around a vast hot-spring bath fed by the mineral-rich waters of Ise-Shima and rooted in Japan's sixth-century onsen bathing tradition — the same waters said to have restored samurai after battle. Two private onsen pavilions and daybeds arranged around a thermal spring garden give guests both communal and secluded ways to take to the water, alongside an Aqua Movement Suite offering watsu and other water-based therapies, a dry sauna and a steam room. Treatments draw heavily on kampo, Japan's centuries-old herbal healing discipline rooted in Traditional Chinese Medicine, which emphasizes restoring balance between body and mind through plant-derived remedies. Amanemu's therapists blend kampo herbs, organic Aman Skincare formulations and locally sourced essential oils into bespoke treatments using seasonal ingredients like pearl powder, seaweed and local herbs; the resort's signature seasonal spa journeys go furthest in this direction, built specifically around the shifting Japanese seasons to rebalance body and mind throughout the year. Four treatment suites and a fitness centre round out the spa's physical offering, with bicycles available at reception for guests wanting to explore the surrounding grounds between sessions. For a more structured stay, Amanemu offers bespoke, multi-day Immersions combining private movement sessions, specialist therapy, spa treatments and complete nutritional support tailored to individual wellbeing goals. Guests with less time can opt for the Wellness Day Program, a single-day retreat that opens with a private movement lesson, followed by a spa treatment and a session with a wellness specialist, rounded out with access to the onsen waters and relaxation facilities. Dining reinforces the same seasonal, restorative philosophy — most notably the Ise Jingu Shrine Breakfast, inspired by the traditional meal served to monks at the nearby shrine — positioning food as a continuation of the resort's broader wellness approach rather than a separate amenity.
