Oko Falls — Oko-no-taki — is Yakushima's great waterfall, an 88-meter plunge on the island off Kagoshima Prefecture's southern coast. Yakushima receives some of the heaviest attention of any small island in Japan, yet its Top-100 waterfall is easy to state plainly: this is one of the taller drops in the entire national selection, and it belongs to an island rather than to the mainland's mountain interior — a rarity on the list. The reading of the name is its own small trap: the characters that elsewhere read "Okawa" (big river) are pronounced "Oko" here, in the island's own way.
