iAP Expanding into Japan—or running a Japanese subsidiary—means dealing with statutory bookkeeping, tax filing, payroll and social insurance under Japan-specific rules, while still reporting to your headquarters in English. iAP is built precisely for this. Here is what makes our service a fit for global companies.
1. Built for global companies
iAP specializes in supporting foreign-affiliated and globally expanding companies operating in Japan. We bridge the gap between Japanese statutory accounting and your head office’s reporting requirements, including US GAAP / IFRS conversion, consolidated reporting packages, transfer pricing and international tax. Whether you are entering the Japanese market, scaling a local entity, or centralizing your back office, we work the way a global business expects—clear engagement letters, defined scopes of work (SOWs), and transparent monthly invoicing.
2. A true one-stop shop
Instead of coordinating separate vendors for bookkeeping, tax, payroll and HR, you get everything under one roof:
- Accounting & bookkeeping — daily bookkeeping, cash management, accounts payable/receivable, monthly closing
- Tax — corporate and consumption tax and filing, with licensed tax accountants
- International accounting — US GAAP / IFRS / J-GAAP conversion, consolidated and head-office reporting
- Payroll & HR — payroll calculation, social insurance and labor procedures, English payslips and policies
Because the same team manages your data end to end—from a transaction through to the report your headquarters reads—nothing falls through the cracks, and you have a single point of accountability.
3. Supported by English-speaking CPAs
Our team includes English-speaking US CPAs, tax accountants and labor specialists who are genuinely bilingual. That means:
- Communication, deliverables and head-office reporting in English (and Japanese)
- Professional standards backed by CPA / JICPA-network quality control and strict confidentiality
- No need to hire and retain scarce bilingual finance staff in-house
You get the technical depth of a professional firm with the day-to-day responsiveness of an in-house team—on demand, scaled to what you actually need.
