Japanese poet who was a major influence in modern Japanese poetry with his aesthetic and symbolic style.

In 1906 he joined the Shinshisha (New Poetry Association) and published poems in its magazine Myōjō (“Bright Star”) that brought him instant fame as a rising young poet. In 1908 he founded, with others, the Pan no Kai (“The Pan Society”) in opposition to the Naturalism that dominated literary circles at that time.

His first collection of poems, Jashūmon (1909; “Heretics”), which depicted the Christian missionaries in 16th-century Japan, won him much praise for the exotic and sensuous beauty of his writing. In 1911 the collection of his lyric poems, Omoide (“Recollections”), was published and also received great praise. Kitahara introduced a new symbolic, decadent style into the genre of the traditional 31-syllable tanka and founded an innovative tanka magazine, titled Tama.
