President's Message

Zaihon will earn absolute trust as your partner for all English corporate documentation needs.

We assist listed companies disclose their information in English

Although we describe ourselves as a translation company, ZAIHON, INC. differs from general translation companies in that it operates in a considerably specialized market. Firstly, our customers are predominantly listed companies and, secondly, our specialty is the Japanese to English translation of disclosure information released by companies. ZAIHON is a fully owned subsidiary of PRONEXUS INC., a long-standing expert in the production of mandatory disclosure material. ZAIHON is committed to assisting listed companies with their information disclosure in English.

We reflect the customer's corporate culture and preferences

The types of documentation that our work mainly consists of, such as financial reports, adhere mostly to a set pattern and the content and structure of such documents vary little between companies. Whenever possible, however, we adopt the terminology that the customer uses in their business operations, which means it is necessary to maintain consistency with the customer's other disclosure documents and previously disclosed information. We carefully peruse a wide range of resources and, upon familiarizing ourselves with these resources, we assist the customer with their English information disclosure in a way that reflects the customer's style.

We place key importance on communication

At ZAIHON, we place utmost importance on our ability to communicate. Communication is key to not only our ability to translate, but also our power of analysis, research capabilities and ability to identify the needs of the customer. Our work is not simply a matter of receiving the original Japanese documents and translating them into English. Whenever possible we meet with the customer to discuss the work before commencement and proceed with the translation workflow. During the production stage, we endeavor to develop a strong communication relationship with the customer, asking questions and making suggestions. In addition, due to the nature of this work, the customer entrusts us with confidential undisclosed information. We receive, transfer, store and manage this information with the greatest circumspection, such as by using highly secure networks managed by General Solutions and Pronexus.

We seek to maximize synergy to raise customer satisfaction

The need for timely English translation of disclosure information is rapidly increasing as the shareholding ratio of foreign investors increases in listed companies. We are always striving to maximize customer satisfaction by quickly, accurately and efficiently producing English documentation with minimum hassle for the people responsible on the customer's side.
