Born in 1874 in Nagamachi-Shinmachi, Onsen District, Ehime (today Minatomachi, Matsuyama) as the fifth son of the former Matsuyama-domain samurai Ikeuchi Masatada. His real name was Ikeuchi Kiyoshi; at nine he was adopted into his grandmother's Takahama family and took the name Takahama Kiyoshi. In middle school he studied haiku under his senior townsman Masaoka Shiki, who in 1891 gave him the pen name 'Kyoshi.' He left the Second Higher School in Sendai in 1894, went up to Tokyo, and joined Shiki. In 1898, the bedridden Shiki entrusted him with the haiku magazine 'Hototogisu'; Kyoshi moved its base to Tokyo and took over editing and management. He initially leaned more toward descriptive prose and the novel, publishing Natsume Soseki's 'I Am a Cat' and 'Botchan' in 'Hototogisu' and carving out a place in the literary world. In 1910, at 37, he moved to Yuigahama in Kamakura and spent the next fifty years there. After Shiki's death, alarmed by the free-meter 'New Trend Haiku' led by his friend-rival Kawahigashi Hekigodo, he returned to the haiku stage in 1913 declaring himself a 'Conservative,' defending the traditional seasonal word and 5-7-5 form through 'objective shasei.' In 1928 he proposed 'kacho-fuei' (singing of flora and fauna) as his doctrine, and through 'Hototogisu' trained numerous poets such as Mizuhara Shuoshi, Yamaguchi Seishi, and Nakamura Kusatao. During WWII he evacuated to Komoro in Shinshu in 1944, composing the 'Komoro Hyakku.' He returned to Kamakura in 1947 and received the Order of Culture in 1954. On April 8, 1959, he died of cerebral hemorrhage at his Kamakura home at 85. He left more than 200,000 haiku in his lifetime.
