With an innate ability to break through barriers, Karson weaves his talent seamlessly into both his career and life.
A Hongkonger with a deep-rooted talent for breaking through complex systems, Karson has built, scaled, and exited businesses across Asia. From playing professional poker in Macau and South Korea to founding profitable ventures in China and Hong Kong, and raising capital in Turkey — every chapter of his journey reflects strategic clarity and fearless adaptability.
Three years ago, Karson arrived in Japan with nothing — no network, no plan B. Through lived experience, he deeply understands what it means to start from zero in a foreign country. Facing cultural barriers and linguistic isolation, he navigated every challenge and built a life and business from the ground up.
Today, he speaks four languages (Chinese, English, Japanese, Korean) and serves as a consultant for foreigners seeking to relocate, invest, and thrive in Japan — with lived credibility and tactical empathy.
