About SANYU

A Japan-Based Partner for Market Entry and Execution

Since 2006, SANYU has helped businesses launch, expand, and strengthen their presence in Japan. Based in Tokyo, we combine practical business support with localization, digital marketing, and hands-on local execution.

SANYU works as an extension of an overseas company’s team in Japan. Depending on the agreed scope, we can support market development, B2B sales and partner activity, B2C e-commerce operations, Japanese customer communication, and ongoing local follow-through. As opportunities mature, an engagement may continue as local representation, develop into distribution discussions, or help prepare a client’s own Japanese operations.
