A legacy system is an information system that is running on outdated technology. Traditionally, Japan can be viewed as a mainframe dependent country. Since the late 1990s, modernization of legacy systems has been under serious considerations. Various approaches for modernizing legacy systems have been presented over the years. However, more than 60% of Japanese companies still possess legacy systems. In this research, the current situation of legacy modernization in Japan is investigated by analyzing actual legacy system. From this study, technical issues and also some non-technical issues have been found which hinders legacy modernization. The fundamental challenge is, managements' lack of long-term vision in maintaining software systems. This paper presents these issues with relation to our model system. Furthermore, technology is always dynamic and any system can become legacy system in the future. Thus, we also propose how organizations can prepare for future migrations through concrete software documentation and establishment of internal policies to govern management of software systems.
