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 or anxiety about the unknown.

With the belief that having an approachable, English-speaking point of contact — before reaching out to local specialists — would make all the difference, he founded Kawana International Tax & Accounting Office upon returning to Japan. He provides end-to-end support from the initial consideration stage through to accounting, tax, and management.
