Hiroya Kawana｜川名 大哉

Representative — Certified Public Accountant & Tax Advisor

After graduating from Waseda University's School of Commerce, Hiroya spent 12 years at KPMG Azsa LLC working in audit and internal control advisory. He subsequently became independent, taking on business turnaround support, financial closing support, and IPO advisory.

During two years at a Singapore accounting firm, he provided wide-ranging support to Japanese companies operating locally — covering accounting, tax, payroll, and management. Through hands-on work with many business owners on the ground, he witnessed a clear reality: many Japanese companies were giving up on overseas expansion simply due to a lack of information.

Back in Japan, he saw the same challenge from the other side: foreign entrepreneurs starting businesses in Japan struggled with complex tax rules and language barriers. With the belief that having an approachable, English-speaking CPA makes all the difference, he founded Kawana International Tax & Accounting Office.

"I know how overwhelming Japanese tax rules can be. Let me make it simple for you."

Frequently Asked Questions

FAQ

Is there an English-speaking tax accountant or CPA in Japan?
Yes. Kawana International Tax & Accounting, based in Fukuoka, provides full English-language tax and accounting services. All consultations, documents, and correspondence can be handled in English. Online appointments via Zoom are available nationwide.
Do foreigners living in Japan need to file taxes?
In most cases, yes. Foreign residents in Japan are subject to Japanese income tax. If you are employed and your employer handles withholding, you may not need to file separately — but if you have freelance income, overseas income, or multiple employers, you will likely need to file a tax return (確定申告, kakuteishinkoku) between February 16 and March 15 each year.
Do I pay Japanese tax on income I earned overseas?
It depends on your residency status. Permanent residents and most long-term residents are taxed on worldwide income in Japan. Non-permanent residents are generally taxed only on Japan-sourced income (with some exceptions for remittances). Tax treaties between Japan and your home country may reduce double taxation. We can assess your specific situation.
Can I get help setting up a company in Japan as a foreigner?
Yes. We support foreign entrepreneurs from the initial setup stage — including advice on corporate structure, tax registration, bookkeeping setup, and ongoing tax filing. A free 60-minute consultation is available to discuss your situation before you commit.
How much does a tax accountant cost in Japan?
Fees vary by service. As a rough guide: personal tax return filing starts around ¥50,000, monthly tax advisory retainers start from ¥25,000/month, and corporate tax filing starts around ¥150,000. The first consultation (60 minutes) is free. Please see our fee schedule for details.
What is the Invoice System (インボイス制度) and do I need to register?
Japan introduced a qualified invoice system in October 2023. If you sell to business clients who claim consumption tax credits, registering as a qualified invoice issuer is generally advisable. We can assess whether registration benefits you and handle the process if needed.
I have overseas assets (property, bank accounts, stocks). Do I need to report them?
Yes, if you hold overseas assets above ¥50 million as of December 31, you must file an overseas asset report (国外財産調書) in Japan. Income from those assets (rent, dividends, capital gains) must also be declared. We specialize in cross-border asset taxation, including Singapore and other Asian jurisdictions.
