In recent years, the aging of workers and the decrease in young human resources have progressed in the Japanese construction industry. Therefore, the lack of future successors has become a serious problem. In particular, it is difficult to secure successors in the Japanese tunnel industry due to the low recognition among young human resources and civil engineering students. Under the circumstances, it is necessary to have young people and civil engineering students recognize and understand about the tunnel industry in order to properly construct and maintain tunnels and hand down the technology to the next generation. it is essential to develop tools that support the early success of young successors and promote their retention in the tunnel industry. In order to solve such problems, simulated experience tools that utilize XR (Cross Reality) technology have been widely used in the construction industry. However, the tools have not been sufficiently developed for the purpose of securing successors in the tunnel industry and supporting their early success. Therefore, in this study, a basic Virtual Reality (VR) system that can simulate the situation (Especially, during tunnel face observation) during mountain tunnel construction was developed by using three dimensional model created based on photogrammetry and unity of game engine. And, questionnaire surveys targeting students was conducted in order to confirm the usefulness of this VR system. As a result, it is clear that it is useful for enhancing recognition of the tunnel industry and initial education for young human resources by utilizing this VR system.
