In this paper, it proposes the method of sharing space that enables collaborative work in the virtual traditional crafting system based on high-speed network (JGN2). We are building the presentation system which deals with human sensitivity in virtual reality environment. So far we have proposed three different presentation systems of an Internet version and a SGI version. In this research, when the business model is considered, we think that collaboration support in sharing space is required of remote users. Therefore, JGN2 which is a next-generation high speed network was used to interconnect remote CAVE systems, and realize of the system which can perform interactive operations in sharing space is aimed.
