In recent years, over 40-year-old scuba divers account for a large portion of scuba diving accidents. Especially, accidents over 40s are almost 100% connected to death accidents. In this way, it is necessary to have an environment where training of scuba can be done easily and safely. In this paper, we propose a wearable type of Underwater VR system. As an initial stage, we developed an Underwater Head Mounted Display (UHMD) prototype system which can resist water and pressure for training system of scuba diving. This system has two functions. One is high immersion feeling the underwater. The other one is to reproduce buoyancy change according to water depth. For these function, user can learn how to control buoyancy under various situations with high reality. The results showed that water resistant performance of UHMD system is enough for use at a depth of about 1.3 meters.
