The flow is significantly wider than it is tall, giving it a distinct horizontal appearance compared to typical vertical Japanese cascades.

Tateshina Otaki is a 25-meter-wide, 5-meter-high waterfall situated within a primeval coniferous forest in Chino, Nagano. The cascade is fed by the Taki-no-yu River and is characterized by its wide, gentle sheet of water flowing over a mossy, rocky ledge. A 10-minute walk through a protected forest leads visitors to the waterfall basin. The site is a popular destination for hikers due to the surrounding lush vegetation and tranquil woodland trail. It serves as a natural transition point for those exploring the wider Tateshina Highlands region.
