田立瀑布, Mountain waterfall in Nagano Prefecture, Japan

Tadachi Falls comprises multiple cascades along a mountain river with steep granite walls separating each stage. A hiking trail runs through the area with built structures allowing visitors to view each cascade up close from different angles.

Tadachi Falls is a group of more than ten cascades in the Kiso Mountains, within the Chuo Alps Quasi-National Park in Nagano Prefecture. The main fall, Tenga Falls, drops about 40 metres. The site was selected for Japan's Top 100 Waterfalls list, a 1990 selection by the Ministry of the Environment.

The falls are counted among Japan's Top 100 Waterfalls (Nihon no Taki Hyakusen), a list that includes the 40-metre main drop, Tenga Falls. The names of the individual cascades, such as Uruu, Rasen, Senshin, Kiriga, Tenga, Fudo, Kakuyoku, Somen and Hakobuchi, are the terms visitors use to tell the stages apart along the gorge trail.

The area has no vending machines or food vendors nearby, so bring your own water and snacks for the visit. The walking path is well-maintained and safe, making it accessible for most fitness levels.

The hiking trail is built directly beside the cascades, offering unusually close views of the falling water at each level. Wooden bridges and stairs position visitors at multiple vantage points rarely found at other waterfall sites.
