Contributing to Foreign Clients through International Tax Expertise
At our office, we specialize in income tax services related to cross-border assignments (global mobility).
We support:
- Foreign nationals who reside in Japan and work primarily in Japan (residents), and
- Foreign nationals who reside abroad but work in Japan (non-residents).
With deep knowledge and extensive experience in Japanese income tax and international tax treaties, we help clients remain compliant with legal obligations across jurisdictions.
If you are struggling with annual tax filings, or hoping to expand your professional presence in Japan, we welcome your inquiry.
We believe in building strong client relationships through thoughtful dialogue.
