Since its establishment in November 2001, Japan Center for Asian Historical Records (JACAR) has released roughly 30 million images of about 2 million digitized historical documents those pertain to relations between Japan and other Asian countries (data from February 2017). This paper provides an overview of documents that were released in the JACAR database, particularly for Taiwanese users. This paper examines a series of documents related to Taiwan and Asia, focusing on a transition to official documents after Japan's surrender in World War II. The documents had originally been digitized by their holding institutions: the National Archive of Japan, the Diplomatic Archives of the Ministry of Foreign Affairs of Japan, and the National Institute for Defense Studies of Ministry of Defense.
