The mail survey is a research method which Nikkei Research adopts as frequently as the Internet survey. The annual number of surveys and handled samples are as large as those of the Internet survey. The number of cases in which a mail survey is utilized has been increasing to conduct a customer survey after the enforcement of the Private Information Protection Law.

Nikkei Research conducts and manages surveys under the management system to handle the mail survey efficiently and safely enough to ensure the protection of private information.

1. Respondents’ private information is not included in the questionnaire. The purpose of this is to prevent an individual from being identified from the questionnaire.
   
   
2. If it is necessary to check whether a questionnaire is returned from individual samples and specific targets, Nikkei Research manages the situation based on IDs, using barcodes.
   
   
3. Nikkei Research has introduced the reward sticker as a means of giving respondents rewards. Nikkei Research asks respondents to return the reward sticker on which the delivery address for the reward is written together with the completed questionnaire. When Nikkei Research sends the reward, it uses the sticker on which the address for receiving the reward is written. This mechanism prevents the respondents’ private information to be retained in Nikkei Research.
   
   
   

Nikkei Research asks respondents to use a product manufactured by a company for a certain period of time as part of the everyday lives and collects their evaluation. For example, in addition to evaluating a new product, it is also possible to have respondents use both a company’s existing product and its competitor’s product and evaluate which product is superior. As respondents use a product in their actual life setting, the results obtained are closer to the actual situations and the remarks are more honest.

Nikkei Research searches existing statistics, research materials, reports, etc and summarizes the information as a report.
Compared to earlier times, the penetration of the Internet has made it far easier to search for and access literature materials and statistical documents at home and abroad. For this reason, the desk research tends to be conducted as the first stage of research, like a preliminary survey of quantitative research. The desk research can also be considered to be an important step in a series of research.
Nikkei Research has a team specialized in statistical data as well as article data for NIKKEI TELECOM 21 (one of the largest commercial database in Japan). Due to the large number of experts in public data, Nikkei Research can leverage its expertise in information searching also to conduct the marketing research to collect appropriate information.
