Inbound Capability

We manage projects seamlessly in both English and Japanese, strongly supporting your global expansion.

Service

Transfer pricing regulations and Japan specific cross-border donation taxation are unavoidable issues for companies engaged in global business in Japan. At MYN, we provide comprehensive consulting services to help you navigate these complex challenges, including hands-on support for the preparation of Local Files.

Comprehensive Local Filing Support

We provide more than just formal compliance. Through the preparation process, we identify current risks and challenges, while also helping you plan for future transfer pricing issues. This standard service plan is designed especially for those addressing transfer pricing for the first time, serving as both practical support and a valuable learning opportunity.

Strategic Audit Defense

Transfer pricing audits inevitably involve differences in interpretation. Our experienced professionals, with a proven track record in reducing or preventing additional taxation, help bridge communication gaps with the authorities by supporting negotiations, attending meetings, and preparing explanatory materials. We also contribute to shortening the duration of audits, which often tend to be prolonged.

Other Services

In addition to local filing and audit defense, we provide advisory services on transfer pricing policies, guidance for both outbound and inbound business expansion, second opinions, and introductions to trusted international tax specialists. We are committed to sharing our expertise and network built over many years, without reservation to deliver the solutions you need.

Message from the Founder

Your Trusted Transfer Pricing and Tax Partner in Japan

Japan remains one of the world’s most sophisticated yet complex markets — full of opportunity, but often challenging to navigate from abroad. While Japan’s transfer pricing rules broadly align with OECD standards, local practice and enforcement can be highly nuanced, creating uncertainty for foreign multinationals managing operations here.
Large global groups have long invested in managing transfer pricing risks. However, mid-sized and inbound enterprises now face similar scrutiny, often with far fewer local resources and preparation. Many struggle to access reliable, practical expertise — and some are forced to compromise on compliance or strategic planning altogether.

At MYN, we were founded on a clear mission:
Empowering all with transfer pricing solutions.

We provide hands-on support in documentation, audit defense, and strategic planning, grounded in deep knowledge of both international principles and Japanese administrative realities. Whether you are establishing your first Japanese entity or seeking consistency across global operations, we serve as your local partner, combining technical precision with business insight.
We believe that trust, transparency, and collaboration are the foundation of every successful international partnership. Guided by these values, we remain committed to helping your organization operate with confidence in Japan — and to contributing, together, to sustainable global growth.
