Insider tip — 'Deai no Yu' (出会いの湯 — encounter spring) at Miyagi Onsen in Taketa city. 'Deai' — the chance encounter, meeting, or discovery — is one of the most evocative concepts in Japanese aesthetics, expressing the fleeting but transformative nature of unexpected connection. Taketa city has its own 'deai' with history: it preserves an extraordinary rural landscape of castle ruins, Christian martyrdom sites (Taketa was a centre of Hidden Christianity), and abandoned copper mining landscapes. Every visitor 'encounters' a different Taketa.
