Insider tip — 'Momiji Yu' (紅葉湯 — autumn maple spring) at Tennen Onsen Kazoku Yu in Yamaga city, Kumamoto — home of Japan's most elegant autumn festival. The Yamaga Toro Matsuri (灯籠まつり — lantern festival) takes place each August: women wearing traditional kimonos balance intricate golden lanterns on their heads and perform the graceful Yamaga Odori dance by candlelight. 'Momiji' (autumn maple) connects the spring to Yamaga's second seasonal beauty — the brilliant October-November foliage that frames the city's temple and shrine landscapes.
