The waterfall is nicknamed 'Jishin-taki' (Earthquake Waterfall) because the powerful sound of the water hitting the basin is said to resemble tremors.
It is officially designated as one of Japan's Top 100 Waterfalls by the Ministry of the Environment.
The drop is approximately 55 meters high.
The water basin is surrounded by columnar joints, which are vertical rock formations resulting from cooling volcanic lava.
Naena Waterfall, located in the Myoko region of Niigata, is a 55-meter tall cascade known as 'Earthquake Waterfall' due to the intense sound generated by its plummeting water. The waterfall is fed by the Seki River, which marks the prefectural border between Niigata and Nagano. The surrounding geological formations feature distinctive basalt columns created by volcanic activity. A well-maintained trail leads visitors from the parking area to two separate observation decks. The lower deck provides a face-on view of the falls, while the upper deck offers a vantage point closer to the spray. The volume of water is significant throughout the year, especially during the spring snowmelt.
The upper observation deck offers a clear view of the waterfall framed by the forest canopy.
Bring a waterproof cover for your camera and phone, as the mist at the viewing platforms can be heavy.
Wear shoes with good grip, as the trail can be slippery near the basin.
Visit during the autumn foliage season for vibrant red and orange contrasts against the dark basalt rocks.
Do not attempt to cross the river or descend into the water basin, as the current is extremely strong and dangerous.
The access road and trail are typically closed during the heavy winter snow season; check local Myoko tourism updates for spring reopening dates.
Stay within the marked guardrails; the terrain around the riverbank can be unstable.
