We assess the tax implications in both Japan and the foreign jurisdiction.

We assist with cross-border matters such as overseas transactions, establishing foreign operations, and owner-managers relocating abroad. We review both sides' tax implications rather than considering only Japan or the overseas jurisdiction.

Accounting and tax systems and professional qualifications differ by country. As a Japanese tax accounting office, we handle Japanese taxation, while local accountants, tax advisers, and other specialists provide advice and filing services under their country's laws.

OneAsia ↗ We use overseas professional networks, including this network, to propose a team suited to your needs. Countries, regions, and the scope of work are confirmed before engagement.

You do not need to change your current tax adviser.

You may retain your current adviser for day-to-day accounting and domestic returns while engaging us only for international tax matters. We cooperate with the existing adviser and provide ongoing support as a second tax adviser.

First, Find Out Whether We Can Help

Pre-engagement Email inquiries is free. Please tell us the countries or regions involved and briefly describe the matter. If a case-specific tax assessment is needed, we will explain our paid consultation options.

To speak with us directly, you can book an international tax consultation (60 minutes, JPY55,000). If local specialists or further work are needed, we will explain the scope and fees separately.
Where consumption tax applies, it is included in the displayed price. Where export exemption applies, the full displayed amount is the consultation fee. Your total payment remains the same in either case.
