Introduction and Practice Profile

Jiwon Koh is an attorney-at-law at Yodoyabashi & Yamagami LPC, operating from both the Osaka and Tokyo offices. He is admitted in Japan and specialises in cross-border legal matters, particularly those involving Japan, the United States, and Korea.

Jiwon's practice covers a broad range of areas, including general corporate matters, M&A and international transactions, regulatory compliance (including pharmaceutical and medical device regulations), labor and employment, litigation and dispute resolution, intellectual property, and real estate. He has particular expertise in the beauty, healthcare, and cosmetics sectors, including advising on regulatory frameworks, advertising compliance, and cross-border commercial arrangements.

He received his J.D. equivalent from Osaka University Law School and was admitted to the bar in 2019. In May 2025, he earned an LL.M. from the University of Southern California (USC) Gould School of Law. He subsequently served as a Visiting Attorney at Jenner & Block LLP in Los Angeles until February 2026 and is currently undertaking visiting attorney secondments at leading law firms in Korea through December 2026.

Jiwon leverages his cross-border experience to advise on both outbound matters—supporting Japanese companies expanding overseas—and inbound matters—advising foreign companies entering the Japanese market. He is particularly experienced in navigating complex regulatory and commercial issues across multiple jurisdictions, especially in the beauty, healthcare, and cosmetics sectors, where he integrates regulatory analysis with transactional structuring, M&A execution, and dispute resolution.

Fluent in Japanese and proficient in Korean and English, Jiwon is well-positioned to navigate complex multi-jurisdictional matters and cross-cultural communications. His practice is distinguished by his ability to integrate regulatory expertise with transactional and dispute resolution experience, particularly in the rapidly evolving beauty and healthcare sectors.
