TKC is a specialized electronic data processing center for accounting firms and local governments.

TKC Corporation was incorporated on October 22, 1966, with its head office located in Utsunomiya City, Tochigi Prefecture.
At the time of incorporation, its founder Dr. Takeshi Iizuka specified the following two activities as the business objectives of TKC to be stipulated in its Articles of Incorporation:

1. Management of the EDP centers for the purpose of defending the business area of public accountants
2. Management of the EDP centers for the purpose of improving the administrative efficiency of local governments

As TKC grew bigger with the expansion of businesses, several other business objectives were added. Yet the first two objectives still remain at the top of the items in Article 2 (Business Objectives) of its Articles of Incorporation, highlighting the initial principles of the management of TKC.
Dr. Iizuka opened an accounting firm in 1946. In 1962, he attended the Eighth World Congress of Accountants in the U.S. and was impressed by how the business of accounting firms was being revolutionized by the use of computers. This experience convinced him to set up a data processing center by himself, dedicated to accounting firms. However, the plan hit a stumbling block, the “Iizuka Case”, and was not carried out soon enough. The Iizuka Case was a criminal action against four employees of the Iizuka Tax Consulting Firm, brought forth by a tax authority. On November 11, 1970, the court found that none of the defendants were guilty. Prior to that in October 1966, Dr. Iizuka had decided to set up a data processing center without waiting for the conclusion of the case.
In preparation for the establishment, he first put down the Management Principle in the Articles of Incorporation. "Defending the business area of public accountants" was that principle. It did not give any hint of the Iizuka Case that was at its height at the time. Indeed, he established a management vision with a broad and ambitious mind and a strong sense of mission.
The start of doing business for local governments was triggered by one phone call from an official of Kuroiso Town (currently, Nasushiobara City), Tochigi Prefecture, in 1966 when TKC was still in its infancy. The town official, who had read a newspaper article about the "Establishment of Tochigi-ken Keisan Center K.K." proposed that TKC should engage in the business of providing services to local governments.
At that time, operations at local governments in Tochigi Prefecture were barely computerized. That proposal was the trigger for TKC to make its entry into the local government market, specifying the objective of "improving administrative efficiency of local governments" in Article 2, Paragraph 2 of its Articles of Incorporation.
(An excerpt from Furusato Nihon 35 (Japan, Our Home Country 35), the booklet published by TKC commemorating its 35th anniversary)

Since then, TKC has consistently developed specialized information services dedicated to its two main focus businesses of accounting firms and local governments and has established its unique position in the information industry in Japan.
Accounting firms and local governments are among the fields that are built on the foundation of legal expertise and profound experience. Therefore, the systems that TKC provides must have specialized capabilities, with full compliance with applicable laws and ordinances. The systems are also required to adapt themselves quickly to revisions of the law and to have high standards of social responsibilities. In other words, TKC’s role in society is to provide support, through information and communication technology (or “ICT”), to certified public tax accountants, certified public accountants, and local government officials with high standards of social responsibilities in carrying out their duties, while maintaining deep knowledge about tax laws, commercial laws, civil laws, administrative laws, and other relevant laws, thereby making a broad contribution to the development of the Japanese economy and local communities.
TKC is committed to continuing the deepening of its expertise, striving to enhance its services and improve quality, and to pursuing innovation in order to fulfill such a role in society.

Today, TKC offers the following information services:
