Insider tip — 'Pokkapoka no Yu' (ぽかぽかの湯 — gentle warmth spring) at Kitano Onsen in Kurume. 'Pokkapoka' is one of the warmest words in the Japanese language — an onomatopoeia for the cosy, gentle warmth of sunlight on skin or a mild hot spring. Kitano-cho, now part of Kurume, was historically a market town on the Chikugo plain. The unpretentious, approachable name of this onsen perfectly captures the community bath philosophy: warmth as the equaliser, available to everyone.
