Insider tip — Ginga no Yu, the Milky Way hot spring, honours Hanamaki native Kenji Miyazawa whose masterwork Night on the Galactic Railroad imagines a celestial train journey across the cosmos. Miyazawa was simultaneously a beloved children author, Buddhist farmer-poet, soil scientist, and composer whose eccentric genius left Hanamaki with a remarkable heritage of monuments, museums, and a rose garden he planted with his own hands.
