The Japan Society of Obstetrics and Gynecology (JSOG) is a Japanese medical society founded in 1949 through the merger of the Japan Society of Gynecology and the Society of Obstetrics and Gynecology, with roots tracing back to 1902.[1] The society’s current website header displays a wordmark-style logo featuring the organization’s name in Japanese characters alongside its English abbreviation.[2]
Design and History
In February 1971, the society published an official notice in its journal, the Journal of the Japan Society of Obstetrics and Gynecology, announcing the adoption of a symbol mark.[3] The notice, titled “Symbol Mark and Publication of Society History,” appeared in volume 23, issue 2 of the journal.[3]
While the society’s own symbol mark was introduced in 1971, JSOG also participates in the “Women’s Health Week” campaign, which it co-organizes with the Japan Association of Obstetricians and Gynecologists. This campaign uses a separate symbol mark designed around the letter “W” from the word WOMAN.[4]
Meaning and Symbolism
The Women’s Health Week symbol mark, distinct from the society’s own emblem, uses the letter “W” as its central motif. Three circles arranged above the W are described by the society as representing three generations of mothers and daughters, as well as women’s physical, mental, and emotional health concerns.[4] The society states that the mark expresses obstetricians’ and gynecologists’ commitment to comprehensively supporting women’s lifelong health.[4]
Regarding the society’s own 1971 symbol mark, the original notice in the journal would contain the official description, but the specific design elements and their documented meanings are not available in the current research sources. Claims attributing the design to Yusaku Kamekura or describing specific visual features of the society’s emblem cannot be verified from available evidence.
