Our mission

Our mission is to support the business growth of global companies by providing professional services based on our extensive expertise in global accounting.

Our services

We are focused on three main services: IFRS and US GAAP implementation for Japanese companies, financial reporting for foreign companies in Japan, and improvements in accounting operational efficiency.

1.    IFRS and US GAAP implementation service

The IFRS or US GAAP implementation project requires a detailed analysis of accounting issues and discussions with external auditors independent of regular accounting work. However, if you proceed without in-house expertise, it could result in a heavy practical burden and schedule delays. In addition, the level of requirements from external auditors has been increasing in recent years, and it is difficult to perform analysis on accounting issues and documentation to a level that satisfies those requirements.

Our solutions:

Our IFRS and US GAAP implementation service supports clients during implementation projects and post-implementation financial closings. This requires a high level of expertise in accounting standards, and we provide customized support to meet the client’s needs in various situations.

Our service includes:

  • Impact assessment of GAAP differences
  • Detailed analysis on accounting issues
  • Supporting preparation of GAAP adjusting journal entries
  • Supporting preparation of financial statements and disclosure
  • Assistance for the discussion with external auditor
  • Development of IFRS accounting policy/manual

2.    Financial reporting services for foreign companies in Japan

If you are a Japanese subsidiary of an overseas listed company or an equity method affiliate, you may be required by instructions from the parent company to submit financial statements and a consolidation package based on IFRS or US GAAP.

Based on our extensive experience in auditing and financial closing under IFRS or US GAAP, we can provide flexible support tailored to your company’s needs, including preparation of financial statements and consolidated package figures for parent company reporting and response to questions from the parent company. We will also provide timely updates on the revision of accounting standards, its impact on your company and the required actions to be taken.

Our service includes:

  • Detailed analysis on accounting issues for new transactions/events
  • Supporting preparation of GAAP adjusting journal entries and financial statements
  • Assistance for consolidated package entry
  • Assistance for the communication with parent company abroad.
  • Advice for the improvements of the financial closing process

3.    Improvements in accounting operational efficiency.

We provide services to improve the efficiency of clients’ accounting operations so that they are able to accelerate their financial closings.

Our service includes:

  • Supporting preparation of financial statements and disclosures
  • Development of accounting manuals
  • Providing financial reporting checklist
  • Advice for the improvements of the financial closing process

We provide high-quality services at reasonable prices. Our representatives have many years of experience with auditing and IFRS/US GAAP advisory services at the Big Four accounting firms as well as experience with IFRS projects and ongoing post-application financial closings as in-house accountants for listed companies.
