Tadachi no Taki is a plural noun. The name covers an entire group of waterfalls — more than ten of them, large and small — strung through the mountains of Nagiso Town in Kiso District, southern Nagano Prefecture. Rather than staking its reputation on one great drop, the site earned its place among Japan's official Top 100 Waterfalls as an ensemble, a sequence of cascades reaching around 40 meters at their tallest. That collective character sets Tadachi apart from the single-plunge falls that dominate the list: here the subject is a whole watercourse stepping down through the Kiso hills, fall after fall, rather than one isolated curtain of water.
