Accounting standards in Japan follow the Japanese Generally Accepted Accounting Principles (GAAP), which differ from the US GAAP and the International Financial Reporting Standards (IFRS). Because of the differences between these standards, it is necessary to make adjustments in how services are delivered. We have formed PKF JAPAN from an exceptional team of Certified Professional Accountants (CPA), Enrolled Agents (EA), and Tax Advisors, who are all former members of the “Big 4” consultancies. We provide a one-stop accounting support service for Japanese corporations and branches, delivering a quality service that is comparable to the other major accounting firms but brought to you at a reasonable price.

Accounting Advisory Services

We provide accounting-related advisory services that we tailor to meet the individual needs of our clients’ businesses based upon their size and their current stage of development. We offer our clients the best possible services, including monthly and annual account closing operations, accounting and auditing support, and compliance with international accounting standards, including IFRS and US GAAP.

  • Accounting Policies Planning
    • We assist our clients in formulating the most appropriate accounting policies for all their various business activities, as well as complying with any new applicable accounting standards. We also help to assess the back-office practices that our clients employ and assist them in the identification of the account methods that they should introduce that would be most beneficial to delivering improvements to both the efficiency and the effectiveness of the practices.

  • Monthly and Annual Closing
    • We help complete the monthly and annual closing of accounts as quickly, accurately, and efficiently as possible. It is vital to obtain the cooperation of all relevant departments, including sales, manufacturing, and development, as well as from any parent company or any subsidiaries. We provide our clients with advisory services to ensure that successful completion of account closing operations.

  • IFRS and US GAAP Conversion
    • Entities in Japan are required to follow the JGAAP when settling their accounts and filing their domestic tax returns. However, if an entity’s parent company is required to follow a different accounting standard such as the IFRS or US GAAP, then it may be necessary for their Japanese entity to transition their financial statement from the JGAAP standard to either the IFRS or US GAAP for consolidated accounting purposes. We offer services that help companies perform this transition smoothly and effectively.

  • Business Flow Building and Improvement
    • We will assess each department’s working practices to determine if they are operating effectively and identify if there are any inefficiencies or opportunities for improvements that we recommend they address. Our team of consultants includes Certified Professional Accountants, Enrolled Agents, and Tax Advisors, who have comprehensive experience across a wide range of different work environments. Our team provides the necessary support required during the preparation and improvement of the workflows that will enhance the efficiency of your company’s work practices.

Accounting Outsourcing Service

Hiring an English-speaking accountant in Japan can be difficult, and it is common for foreign companies to outsource their accounting functions. We offer bookkeeping and payment processing services to meet all your outsourcing requirements. We can also tailor our software and reporting processes to meet the specific needs of both your company and your overseas parent company as a fully integrated and transparent service, acting as if we were your company’s own in-house accounting and tax department.

  • Accounting Outsourcing
    • Here at PKF JAPAN, we have a team of professional staff who are experts at undertaking accounting tasks on your behalf, including preparing your books. We offer bookkeeping services that are compliant with accountancy standards, including IFRS and US GAAP. We will also compile, on request, a comprehensive management summary for you to use in your monthly meetings. We deliver operational efficiencies to your business using cloud accounting software in conjunction with our support services, allowing you to focus your management resources on your core business while we seamlessly manage your accountancy needs.

      Bookkeeping services as part of a larger BPO service

      Bookkeeping is an important task that provides the foundation for producing accurate accounting books and precise financial and tax filings. However, bookkeeping is not the only Business Process Outsourcing (BPO) service that we offer. We also deliver outsourcing for other tasks for your upstream processes, including the following:

      • Payment Processing (cash, bank transfer)
      • Invoice Preparation
      • Payroll Calculations
      • Social Insurance Processing.

      As these other outsourced offerings are closely tied to the bookkeeping processes, outsourcing these tasks to us, in addition to your bookkeeping, would deliver to you benefits of scale and help make your business processes more efficient and effective.

  • Invoice Issuance
    • Our team at PKF JAPAN can both prepare and submit your sales invoices to your clients on your behalf. We can follow your standard invoice format; alternatively, we can use our cloud software solution to prepare your invoices. Another available option, as part of our offered BPO services, is to use our accounting software linked to the cloud invoicing software solution. This integrated solution can significantly increase the efficiency and accuracy of recording and tracking of your invoices and associated payments.

      Invoice Preparation

      Our team at PKF can prepare sales invoices on your behalf. We tailor our services to meet your requirements, such as issuing invoices at fixed dates, or multiple times over each month, or using any specified software solutions.

      Invoice Sending
