RSM Shiodome Partners is the Japan member firm of RSM International, one of the world’s leading audit, tax, and consulting networks with more than 900 offices across 120 countries. Supported by this global platform, we provide practical, forward‑looking solutions built on deep technical expertise and real experience in international business.
Expanding into Korea offers significant opportunities, but it also requires navigating unfamiliar regulations, business customs, and cultural expectations. Many Japanese companies discover that success in Korea depends on more than understanding the rules. It requires a partner who can interpret the local environment, anticipate risks, and guide decision‑making with clarity.
Our Korea Desk was created to provide exactly this kind of support. By working closely with RSM Korea and other RSM member firms around the world, we deliver integrated assistance across accounting, tax, legal, HR, and operational matters. Our consultants are fluent in Korean, Japanese, and English, which ensures smooth communication and eliminates the friction that often slows cross‑border projects. Whether you are entering the Korean market for the first time or expanding an existing presence, we offer tailored support that helps your business move confidently and compliantly.
