About CKO Tax & Accounting
Tax and accounting support for foreign residents and businesses in Japan.
Tax and accounting in Japan
CKO Tax & Accounting provides Japanese tax and accounting support for foreign residents and business owners in Japan.
The Japanese tax system can be difficult to follow, even for native speakers. For foreigners — whether employed, freelancing, or running a company — keeping up with obligations, deductions, and filing requirements takes time and knowledge most people simply don't have spare.
We handle the paperwork and explain what matters in a clear and practical way.
What we do
We support foreign residents with their annual tax filings — including those with multiple income sources, RSUs, rental properties, or freelance earnings.
For business owners, we handle company incorporation, annual corporate tax, bookkeeping, and ongoing accounting support.
For clients who have left Japan but still have Japanese tax obligations — rental income, pension payments, or other Japan-source income — we manage filings and NTA correspondence entirely remotely.
