About

CKO Accounting & Tax Office

CKO Accounting & Tax Office supports overseas companies operating in Japan, as well as their Japanese subsidiaries and branches, with accounting, tax, and financial reporting.

From bookkeeping and monthly and annual closing to Japanese tax filings and compliance, we provide practical support tailored to each company’s operations in Japan.

We also support reporting to overseas headquarters and parent companies, J-GAAP / IFRS adjustments, the alignment of accounting policies and finance processes as part of post-merger integration (PMI), and improvements to finance and accounting processes through standardization and automation.

Our mission

To clear the way for global businesses in Japan.

We believe accounting, tax, and finance operations in Japan should not become barriers for global businesses moving forward here.

CKO helps companies run the finance function they need without having to build a large local finance team, so they can operate steadily and keep moving forward.

Who you’ll work with

CKO is led by Chisako Funakawa, a Japanese Certified Public Accountant (CPA) and Licensed Tax Accountant.

Her experience includes audit work at KPMG, as well as in-house roles spanning finance, accounting, and corporate planning at a pre-IPO company. She has also supported companies ranging from small businesses to pre-IPO and listed companies, adapting accounting and tax support to different company sizes and stages of growth.
