Subaru no Sato is a comprehensive resort in Totsukawa Village, Nara Prefecture, known as Japan’s largest village by area. Combining hot spring bathing, accommodation, and recreational activities, it offers visitors a chance to unwind amid mountains that change with the seasons and the soothing sounds of flowing rivers. The grounds cover more than approximately 8,000 tsubo, or 26,400 square meters, providing plenty of space to relax and refresh both body and mind in a peaceful natural setting.
The resort’s central facility is Hoshi no Yu, a hot spring bathing complex where visitors can enjoy water drawn directly from the Totsukawa Onsen source. The baths use 100% free-flowing hot spring water, without reheating, adding water, or recirculating it. This commitment to preserving the water in its natural state is a distinctive feature of the resort.
Totsukawa Onsen is traditionally said to have been discovered by charcoal makers during the Genroku era (1688–1704). The area was subsequently developed as a hot spring destination in 1963. In 2004, Totsukawa Village made a declaration that all bathing facilities at its three hot spring areas—Tosenji Onsen, Totsukawa Onsen, and Kamiyu Onsen—would use free-flowing spring water. The village became the first hot spring destination in Japan to make such a commitment across an entire region.
Hoshi no Yu offers nine types of bathing experiences, including indoor and outdoor baths, a hinoki cypress bath, ceramic baths, a waterfall-style shower bath, a reclining bath, a low-temperature bath, a square wooden bath, and a small bowl-shaped bath. From the outdoor bath, visitors can look out over the green mountains and enjoy the relaxing sensation of bathing in harmony with nature.
The hot spring water is classified as a mildly alkaline sodium bicarbonate spring, with a pH of 6.9. Its reported natural flow rate is approximately 800 liters per minute.
The water is often described in Japan as a “beautifying bath” because it can leave the skin feeling smooth. It is also traditionally associated with relief from cold sensitivity, neuralgia, rheumatism, frozen shoulder, cuts, and burns. Many visitors appreciate how the warmth seems to linger after bathing, helping them feel comfortable even after leaving the water.
A drinking station is also available at the facility, where visitors can sample the hot spring water in small quantities. Drinking hot spring water, known as insen in Japanese, has a long history at certain Japanese hot spring destinations. Visitors should follow the facility’s guidance on whether the water is suitable for drinking and the recommended amount, rather than assuming that all hot spring water is safe to consume.
This additional experience offers another way to learn about the local hot spring culture, alongside the more familiar pleasure of soaking in the baths.
Another major attraction at Subaru no Sato is its indoor swimming pool, which uses water from Totsukawa Onsen. Hot spring swimming pools are relatively uncommon in Japan, and the indoor setting allows visitors to enjoy swimming throughout the year.
The main pool measures 25 meters in length and has six lanes, making it suitable for proper swimming and exercise. A separate shallow pool is also available for young children, making the facility popular with families.
Swimming provides an enjoyable way to stay active during a relaxing hot spring getaway. Large windows offer views of the surrounding landscape, allowing swimmers to appreciate the changing scenery while exercising in a comfortable indoor environment.
Hotel Subaru, located within the resort grounds, is a peaceful accommodation facility that makes generous use of wood to create a warm, welcoming atmosphere. Its location near Yanagimoto Bridge, close to the descent from the Hatenashi Pass route of the Kohechi pilgrimage trail on the Kumano Kodo, makes it a convenient place to rest after a long day of hiking.
After walking the mountain trails, guests can soak in the free-flowing hot spring water and give tired muscles a chance to relax. The resort also has a multipurpose open space, foot baths, a hot spring water dispensing station, and a pet house, catering to a variety of visitors.
At night, the sky can fill with stars, while the quiet mountain surroundings create a sense of peace rarely experienced in large cities. Staying here offers an opportunity to slow down and enjoy the natural beauty of Totsukawa.
One of the most distinctive activities at Subaru no Sato is the yaen, a traditional human-powered ropeway unique to the Totsukawa area. Passengers sit inside a small suspended platform attached to a wire cable stretched across a river, then pull themselves toward the opposite bank by hauling on the rope.
The name yaen means “wild monkey.” It was inspired by the way monkeys move through trees by gripping vines and branches. Before bridges became available, similar devices served as practical means of crossing rivers in remote mountain communities. Today, the yaen has been recreated as a recreational attraction that offers visitors a taste of this distinctive local tradition.
Moving slowly above the river provides a combination of excitement and exhilaration, almost like traveling toward a secret hideaway suspended in the air. The attraction is free to use and is located within the Hotel Subaru grounds.
The yaen is designed for one person at a time. Keep your fingers clear of the wire cable and pulley to avoid trapping them. Sit in the center of the suspended platform, and do not lean out or deliberately rock it while crossing.
Subaru no Sato combines the relaxing warmth of hot springs, the enjoyment of swimming, and the adventure of riding the yaen in one destination surrounded by the mountains of Totsukawa. Its spacious grounds and multipurpose outdoor areas also make it suitable for families, friends, and group trips.
The abundant hot spring water, distinctive mineral qualities, and unspoiled natural environment make this resort an inviting place to take a break from everyday life. Whether you come to soak in the baths, enjoy outdoor activities, or spend a quiet night beneath the stars, Subaru no Sato offers a relaxing mountain retreat in every season.
