Tell us about your Japan-related tax matter and the help you need. Every inquiry is reviewed directly by a qualified professional who is a Certified Public Tax Accountant (Zeirishi) and also a Certified Public Accountant (CPA).

The Free Eligibility Check includes a free scope check and quote based on basic, non-sensitive information. A paid written review is not required for a standard quote. Tax advice, detailed calculations, and document review are separate paid work agreed in advance.

Common Types of Inquiries

What Happens Next

  1. Free Eligibility Check and Quote
    Use the form to share basic, non-sensitive facts. We check service fit and the proposed scope, and provide a free quote. Standard cases can proceed directly to engagement without a paid review. Submitting an inquiry does not create a client relationship.
  2. Optional Paid Written Review
    Where appropriate, we may offer an Initial Written Case Review. The fee is JPY 80,850 (JPY 73,500 plus consumption tax where applicable). A Complex Written Case Review starts from JPY 115,500 (JPY 105,000 plus consumption tax where applicable).
    If you begin an eligible annual service within 90 days after the written review is completed, we credit the full review fee actually paid against the first-year fee. This does not apply to one-time property sale filing, even when tax representative work is included. See our Fees page for details.
  3. Separate Engagement
    A separate engagement begins after a written agreement confirms the scope, exclusions, fees, responsibilities, and required documents. The agreement also sets the service start date.

Response Time

We will send an acknowledgment email within 3 business days.

Japanese weekends, public holidays, missing facts, and complex inquiries may affect our response time.
