Insider tip — 'Ume no Ka Onsen; Tsudoi no Yu' (梅の香 — plum blossom fragrance; 集いの湯 — gathering spring) at the Oyama-machi welfare centre in Hita city. Oyama-machi is famous for its 1960s-70s 'Ippon Matsu' (One Pine Tree) rural revitalization movement — transforming Japan's poorest village through innovative agriculture and community organizing, becoming a global rural development model. The gathering spring in this pioneering community carries the plum blossom fragrance of early spring — the season of renewal and first blooms.
