He graduated from The Medical School of Tokyo Imperial University (東京帝国大学医科大学, Tokyo Teikoku Daigaku Ika Daigaku) in 1900, and went on an overseas study program to Gustav Killian at University of Freiburg in 1903. Four years later he returned to Japan, where he took up the post of professor at Fukuoka Medical School. There is a small museum at Kyushu University honouring his achievements.
