ACCOUNTING & FINANCIAL SERVICES Service Overview

Supporting global management beyond double standards in accounting

One of the most significant challenges for foreign companies operating in Japan is navigating the differences in accounting standards.
Companies are often required to report to overseas headquarters under US GAAP or IFRS, while simultaneously complying with Japanese accounting standards, the Companies Act, and local tax regulations.
Managing this dual framework accurately, efficiently, and consistently is critical to maintaining management reliability.
ARK’s multilingual accounting professionals provide comprehensive accounting outsourcing services that go far beyond basic bookkeeping.
We support not only daily accounting operations, but also ERP utilization, English financial reporting, and internal control design, enabling seamless alignment between Japan operations and global headquarters.
We function not as an external vendor, but as an extension of your finance team, supporting your global management from behind the scenes.
