History
Minamiaso Mizu-no-Umareru-Sato Hakusui-Kōgen Station opened on 1 April 1992 on the Takamori Line operated by Minamiaso Railway, in the foothills of Mount Aso. At opening its 22-hiragana kana reading made it the longest railway station name in Japan, a title it shared with Chōjagahama-Shiosai-Hamanasu-Kōen-mae Station and which it lost, regained, and lost again as other stations were renamed; both were finally surpassed in 2015 by a Toyama tram stop with a 24-hiragana name. The 2016 Kumamoto earthquakes shut the Takamori Line down, and through service via this station resumed only on 15 July 2023 after Tateno - Nakamatsu reopened.
