Audit and Accounting

English /  日本語

As one of our core service lines, we serve our clients by working closely with Tohmatsu and other firms within the Deloitte network in order to provide a globally integrated, risk based, audit. This includes providing consolidation clearances to Japanese parent firms in line with their annual and semi-annual reporting deadlines as well as local statutory audit and, wherever required, accounting advice. In addition, we also provide other ad hoc services to clients as needed, including accounting investigations, domestic and international accounting advice and treasury services.

Our service and methodology is globally integrated and focuses on the risks of your business. We place a premium on communication, both within the Deloitte network to ensure the smooth running of all your audit requirements as well as with each local business, its parent companies, subsidiaries and advisors to ensure that each aspect of your business receives the attention required in order to deliver a robust opinion.

You require high standard audit delivered in a cost-effective way. Our audit approach is designed to achieve this; it is embedded in AuditSystem/2, a computer-based and risk-focused package. We describe our methodology as a “top-down, risk-based controls approach”. This means we focus on:

  • understanding your business more;
  • identifying and evaluating the key risks in your business;
  • identifying and testing the key controls over them; and
  • reporting any weaknesses and carrying out further testing as necessary.

This will be applied rigorously, but with common sense. We will focus on key controls because audit strategy and plans will be discussed and agreed with you before detailed audit testing commences to ensure that they take account of any specific concerns you may have, and to ensure that they are efficient.

The main benefits of our approach to the audit will be:

  • the delivery of effective audits by focusing on your needs and expectations;
  • added value by helping you strengthen controls over business risk through our “top-down” approach to controls testing; and
  • efficient management of the audits by incorporating quality through early planning, anticipating problems and avoiding surprises.

To ensure these benefits are achieved, our Partners will be actively involved throughout the audit process from the planning stage through to our final reporting.

Internal Audit & Risk 

Worldwide, businesses organisations are continuing to adjust to the widespread propagation of enterprise systems aimed at producing more and better results with increasingly fewer resources. Securing timely and reliable business intelligence for your senior management team has probably never been more important.

Would you like to establish an internal audit function, or extend the scope of your existing one so it contributes much more to shareholder value? Would you prefer to simply have specialised support readily available to fill gaps in coverage? Or would you like to know how well your internal audit function compares against best in class? At Deloitte we can develop a customised value proposition for your organisation to meet these and many other needs.

Technology Assurance & Advisory 

Technology Assurance & Advisory (TAA) is a UK team of 350 technology risk and security professionals which supports senior management who have responsibility for IT. Ours is a straightforward approach, which steers clear of jargon and consultant buzz words whilst offering an all-inclusive service in three key areas:


We help to manage the every day risks of operating technology; trying to pre-empt what could go wrong in the technology environment and help remedy issues before problems arise. The types of areas under consideration would be; the integrity and reliability of data, the security of applications and infrastructure, and the alignment of technology with business processes and internal controls. We also help to manage legal matters such as outsourced service management, software licence compliance, illegal content and privacy protection.


When an organisation is undergoing significant technological change, we help manage the associated risks. We provide independent evaluations of projects and quality assurance activities, such as systems testing and data conversion to help ensure all operational matters are addressed before any change is deployed. We also assist clients on end user training, security integration and business continuity plan development.


IT governance is a hot topic and our TAA team helps clients understand and meet the governance challenge with an integrated approach, across jurisdictions, addressing industry regulation, statutory and audit compliance. We can help develop a governance approach that starts with strategic IT planning, monitoring and risk reporting, and goes down to the actual controls required within an IT environment; to be in control and be seen to be in control by key stakeholders.


Our ERS practice provides a wide variety of J-SOX readiness services. We can assist clients throughout all phases of the followings;

  • project initiation and planning,
  • documentation of internal control,
  • assessment of internal control, and
  • internal control testing and remediation.
