Ousen no Taki Falls

Ousen no Taki, located in Kusatsu Town in Gunma, lies about ten minutes by car from the lively Kusatsu Onsen district, tucked quietly into a remote mountain valley. The waterfall drops roughly 25 meters, and its rock face glows a reddish brown because iron in the hot spring minerals has oxidized over time. True to its name, the soft and graceful flow of water wraps visitors in a distinctive calm. Its unspoiled simplicity makes it a healing power spot known to a select few. The path down to the basin is framed by trees, offering time filled only with the murmur of water and the calls of birds.

Highlights

• Striking rock walls stained reddish brown by iron-rich hot spring minerals
• A soft and elegant flow of water that inspired the falls name
• A nature-filled walking path descending from the parking area to the basin
• Negative ions felt in the quiet embrace of the forest
• A distinctive landscape shaped by hot springs, unique to the Kusatsu-Shirane volcanic zone

Enjoying the Seasons

In the fresh green season, the contrast between vivid foliage and red rock is beautiful, and in autumn the surrounding trees turn color for a fine pairing of leaves and falling water. After rain the volume of water increases and the flow gains force. The elevation is high and snow or ice makes access difficult in winter, so a visit from spring through autumn is recommended.

Access and Basic Information

• Location: Kusatsu, Kusatsu Town, Agatsuma District, Gunma Prefecture
• About ten minutes by car from the Kusatsu Onsen district
• Walk from the parking space along a path to reach the falls (a downhill route of several to a little over ten minutes each way)
• Wear comfortable clothing and non-slip shoes for the mountain trail
• With no lighting in the mountains, visit during bright daylight hours before sunset

Practical Travel Notes

• There are almost no restrooms or shops around the falls, so it is wise to take care of these in the Kusatsu Onsen district before heading out.
• The path descends on the way in and climbs on the way back. Those unsure of their stamina should plan with extra time.
• Road and trail conditions change easily in winter and after heavy rain, so check the weather and road information in advance.
• Mobile phone signal can be weak in places. Visiting with companions rather than alone is recommended.
• Combined with the Yubatake hot water field and Sainokawara Park in Kusatsu, you can enjoy both the townscape highlights and this quiet waterfall in half a day.

A Quick Tip

The path to the falls has some ups and downs, so comfortable shoes are a good idea. Combine it with Kusatsu Onsen to enjoy both bustle and quiet in a single day. It is not showy, but the red-stained rock and gentle flow form a scene unique to a hot spring region, making it perfect for a quiet breather away from the crowds.
