THE WINTER SUN SHINES IN: A LIFE OF MASAOKA SHIKI By Donald Keene (New York: Columbia University Press, 2013, 240 pp., $35, cloth) In the midst of a changing society where Japan was quickly westernizing, Masaoka Shiki, a haiku and tanka poet at the turn of the century in Japan, had modernized the nation’s ancient poetry without losing its identity. Donald Keene, professor emeritus of Columbia University and an expert on Japanese literature who has penned more than 30 titles, writes Shiki’s biography through the poet’s own writings and accounts from those around the innovative poet. Keene illustrates a vivid but tragically short life of a poet, while exploring his own connections to the innovative work Shiki left behind.
