In this paper, a promising way of forming and penetrating security sense among employees in Japanese firms is clarified through the case study of Japanet Takata. The Personal Information Protection Law enforced in 2005 has raised customers' privacy protection awareness among businesspeople. Establishing proper information security measures for protecting customers' information privacy has become very important for firms. Once firms make trouble concerning security of personal information, it becomes urgent for them to set up and implement the recurrence prevention plans. Nevertheless, there exist firms in which information security incidents such as personal data leak happened repeatedly. On the other hand, Japanet Takata surmounted the incident of customer information leak and has become one of the most trustworthy firms in terms of personal information security. This has resulted in a significant increase in their sales.
