Umnagumo Plastic Surgery is a breast surgery–dedicated clinic located on the 6th floor of SB Tower in Gangnam-gu, Seoul. Founded in 2003 as the Korea branch of Tokyo Nagumo Clinic (established 1988), the practice has focused exclusively on breast surgery for over 25 years. Trans-axillary scarless breast augmentation is the clinic's signature procedure, and the team has extensive experience in both primary surgery and revision of cases performed elsewhere.
Founded in 2003 in Gangnam, Seoul, by Dr. Eom Soon-chan, who served as the first Korean Chief Surgeon at Nagumo Clinic Tokyo. The Korean practice transposes the surgical protocols, instrumentation, and quality standards of the Japanese parent group to a Korean clinical setting.
Specialty: Trans-axillary (under-arm) breast augmentation and revision. The incision is hidden in the axillary skin fold, leaving no scar on the breast itself. The clinic has built a dedicated trans-axillary system since 2005 and applies this approach to both primary and revision cases when anatomically suitable.
Languages: Korean, English, Japanese. Dr. Eom completed his PhD in Medicine at Kyoto University and is fluent in Japanese.

Umnagumo Plastic Surgery is the Korea branch of Tokyo Nagumo Clinic, originally established in 1988 in Ueno, Tokyo. The Korean clinic was opened in 2003 by Dr. Eom Soon-chan, who served as the first Korean Chief Surgeon at Nagumo Clinic Tokyo. The Tokyo clinic group operates four locations across Japan: Tokyo, Nagoya, Osaka, and Fukuoka.
Trans-axillary breast augmentation is a surgical technique where the implant is inserted through an incision in the armpit (axilla), following the natural skin folds. This leaves no visible scar on the breast itself, and the axillary scar typically fades into the natural folds within 6–12 months. Umnagumo has built a specialized trans-axillary breast surgery system since 2005 and applies this approach to both primary and revision cases when anatomically suitable.
