In recent media, amount of information related to food is remarkable. There is a flood of information about food on TV and the Internet 24 hours a day.

Tabelog, a restaurant guide in Japan, occupies a central part of widespread information about food. Tabelog is a site that the general public attaches importance to when choosing a restaurant, and its ratings have strong influences on operating results and profits of restaurants. However, various problems such as ambiguity in the rating method and existence of fake ratings and buzz marketing - both aiming at intentionally improving evaluations - have been pointed out.

The purposes of this study are to discuss the gourmet evaluation situation before and after Tabelog, to compare and discuss the positive and negative aspects, and to consider the future direction.

The purpose of this study is to expose what factors affect the acceptability of credit score services. In the analysis, conjoint analysis was performed based on the questionnaire survey. The survey revealed that the bounded rationality exists for individuals in the use of credit score services. The results of the conjoint analysis also revealed that scores are erased after service suspension and that opt-in consent is important. Furthermore, it was revealed that credit score services are not well recognized and that many individuals who are not aware of credit score services are resistant to them. Through this study, it was shown that further recognition is needed for credit score services to become more popular in the future. In addition, we have shown that there is a need for policies that support the limited rationality of individuals for future credit score services.
