Originally established in October 1992 and incorporated in February 1996, OC & Associates K.K. (formerly Okamoto & Company) is a four–partner accounting firm, specializing in accounting outsourcing, auditing, payroll/statutory benefits services to foreign companies in Japan. Our client sizes range from one–person SOHO type startup offices to subsidiaries with over 2,000 employees. Tax services are being provided by OC & Associates Tax Co., an office located next to OC & Associates K.K. This allows for the important integration between our accounting and tax services as tax treatment are often guided by the accounting treatment. We are also one of the few accounting firms in Japan registered with the PCAOB (Public Company Accounting Oversight Board) and have also obtained a Type1 ISAE 3402 Report for our payroll services. A subsidiary office was established in Singapore in October 2014.
