Objective: The communications between Asian countries are growing. In the field of medical information and technologies, the necessity of communication is also required. In this work, as communication of pathology field, we tried to prove that international remote pathology diagnosis is possible using virtual microscopy (VS) telepathology. Method: We put VS scanner and server to 1) our Hospital, Tokyo, Japan, 2) Cho-Rai Hospital, Ho-Chi-Minh city, Vietnam, and 3) Chinese Rehabilitation Research Center, Beijing, China. Pathologists go and look the VS through leased optical line circuit and make diagnosis. Discussion was made through teleconference system. Results: The VS image maintained adequate quality for pathology diagnosis even looked cross-border. The diagnoses matched well between hospitals. The response of VS viewer was also good this time. When we use too much band width to the Teleconference system or we sent too many data in the background, the response deteriorate, and was not good enough for diagnosis. Conclusion: It was confirmed that the international VS telepathology diagnosis is now reached to a stage of actual use at least when connected by leased optical line circuit.
