The Japan Pediatric Society was established on December 3, 1896, as the same day as the founding meeting of the Pediatric Research Society at the Nihon-bashi Kairakuen in Tokyo, and such was later recognized as the first general meeting.
Previously (1890), several physicians working in the field of pediatrics at the Tokyo Imperial University had met under the name of the "Mumei-kai". Two years later, the name was changed to the " Showa-kai" with the participation of Prof. Osa Hirota of the Department of Pediatrics, Tokyo Imperial University.
The society had 45 members nationwide in 1895 and published 100 copies of the first edition of its official journal entitled "Pediatrics".
