HOTEL THE MITSUI KYOTO has renewed its wellness programme for staying guests, SPA Indulgence: Onsen Wellness Journey, inspired by the long tradition of hot springs as places of healing and restoration. The programme has been reimagined around the theme of restorative sleep.
Returning to the origin of the word spa, meaning water, the experience focuses on supporting the body’s natural circulation of water to ease daily fatigue and gently guide guests towards deep, restorative rest.
The spa treatments incorporate camellia oil from Kazurasei, a historic Kyoto brand founded in 1865 that has supported the beauty of Kyoto’s women for generations. Through original treatment techniques and the nourishing qualities of camellia oil, the programme offers a deeply relaxing experience.
Guided by the hotel’s brand concept, EMBRACING JAPAN’S BEAUTY, this unique stay brings together traditional Japanese beauty culture and the heritage of therapeutic hot springs, elevating them into a contemporary wellness retreat.
A Water-Inspired Journey to Restful Sleep Guided by a Dedicated Spa Concierge

The programme is centred on water, which makes up around 70 percent of the human body, and aims to support the body’s natural internal circulation.
A dedicated spa concierge begins with a personal consultation and carefully tailors the stay to each guest’s individual needs. Through four elements, hot spring bathing, treatments, cuisine and wellness activities, daily tension is gently released, as if carried away by water, guiding the body towards a healthy and natural sleep cycle.
Kyoto Nijo Onsen and Private Onsen: Preparing the Body for Deep Rest
Guests may enjoy Kyoto Nijo Onsen, a natural hot spring located some 1,000 meters directly below the hotel property, within our spacious Private Onsen area spanning over 100 square meters. The adjoining steam room offers a herbal steam experience using traditional Japanese mugwort, encouraging gentle perspiration. Two types of body scrubs scented with sake lees and mint, together with a clay pack, leave the body refreshed and revitalized.
Exclusive Treatments Featuring Kazurasei Camellia Oil
During the stay, guests experience three treatments, including the hotel’s Signature Treatment and an exclusive treatment created for this program using camellia oil from Kazurasei, a Kyoto establishment that has supported traditional beauty culture since the late Edo period. Combining the deep nourishment of high-quality camellia oil with original treatment techniques, the most suitable combination is carefully selected from six treatment options. These personalized treatments promote circulation, gently release physical tension, and prepare the body for restful sleep.
A Nourishing Dining Experience: Supporting Rest from Within
Dinner is served in the Private Onsen as a specially designed maintenance dinner, created to nourish the body from within and prepare it for restful sleep. Drawing on the rich bounty of Kyoto, the menu incorporates the benefits of fermentation, including lactic cultures, koji and Daitokuji natto. This approach connects the outer refreshment of the spa experience with inner wellbeing. The meal provides gentle nourishment without placing strain on the body before bedtime and supports a deeply restorative night’s rest.
Wellness Activities for Mind and Body
Moments of mindfulness are woven throughout the stay. The experience begins with breathing measurement and breathing techniques using singing bowls, encouraging awareness of the breath.
During the morning Private Onsen bathing experience, guests may choose one of three wellness activities:
• Yoga
• Stretching and breathing exercises
• Water meditation
Through conscious breathing and gentle movement, the body’s autonomic balance is gradually restored, allowing both mind and body to settle into a state of deep relaxation.
