Moon and Sun's Special Features
Authentic Finnish Sauna Stoves
All Moon and Sun saunas feature authentic Finnish MISA stoves. You can enjoy authentic hot waves through self-löyly anytime.
Steam (löyly) generated by pouring water on sauna stones increases the perceived temperature and promotes sweating. Enjoy the ideal sauna experience at your preferred temperature and humidity.

Fragrant Sauna Scents Available
At Moon and Sun, all villas offer original sauna scents created in collaboration with Artemis Herbal Shop, which provides natural sauna herb scents. Experience ultimate relaxation with these aromatic sauna scents.
<Exclusive to The Moon and Sun EN ATAMI>
We offer two types of sauna scents blended with themes for the two sauna rooms.
陽の木 -hi no ki- (Sun Wood)
The mystical scent of hinoki cypress, whose name derives from either "fire" or "sun" wood. Combined with the refreshing and gentle aroma of ho wood, it continues with the warm undertones of labdanum and patchouli reminiscent of sunlight. For warm, powerful moments that awaken your divine nature.
月の香 -tuki no ka- (Moon Fragrance)
A penetrating fragrance combining Koya-maki from the sacred grounds of Shingon Esoteric Buddhism with the serene woody notes of pine family trees. As evening falls and quiets, the deep grounding scents of spruce and vetiver spread through the space. For moments of calming both mind and soul.


<Other Villas>
We offer three types of sauna scents blended around morning, noon, and night themes, inspired by the moon and sun.
mezame -The Beginning of Good Things-
Herbal notes of sage, lavender, and rosemary dissolve into the clear morning air. Allow your body and mind to resonate with the sacred energy of frankincense, a fragrance for spiritual prayer, and begin your fresh day. Start with morning "totonoeru" to invite good fortune for the day ahead.
arucu -As Your Heart Desires-
The powerful scent of tea tree leads this woody note, energizing your life force and protective energy. Lime adds spicy playfulness, allowing you to feel as free and carefree as walking through a forest. For healthy breathing on this once-in-a-lifetime day.
tumulu -Wishes Come True-
Like the lingering warmth of the daytime sun, orange and bergamot gently envelop the end of your day. Surrender to the gradually shifting stability of hiba, patchouli, and the rich grounding of birch tar, restoring smooth energy flow. For releasing daily tension and preparing for sleep.
