History

The place is said to take its name from a Sengoku-era tragedy. A travel diary written by Yamada Sanae in 1842 records it as 「Gojunin-buchi」 (Pool of Fifty), and it has also been called 「Gojugonin-buchi」 (Pool of Fifty-five). The kanji spelling 花魁淵 is in fact rarely used; the name is more often written phonetically, and the character for the pool itself varies. The legend behind the name is still passed down today.
