Insider tip — 'Daichi no Yu' (大地の湯 — spring of the great earth) at Park Club Onsenkan in Taketa city. 'Daichi' — the great earth — invokes the geological scale of the forces producing Taketa's thermal springs: the ancient Aso volcanic system whose caldera collapse, 90,000 years ago, produced the landscape in which Taketa's Oka Castle, its copper mines, and its springs all exist. The 'great earth' name acknowledges that this thermal water is not a human creation but a planetary one.
