In this paper I discussed the Japanese Naval radar research and development program and the mobilization of science and technology during WWII. The Radio Research Department (Denpa Kenkyu-Bu) which was the new radar research and development department was established in Naval Technical Research Institution (Kaigun Gijyutu Kenkyu-jyo) at July 1943. Many outside scientists and engineers were appointed into the a part time civil servants (Shokutaku) who were conformed to the naval 1942's Shokutaku rules. RRD was able to use this rule for their own intention, and some of Shokutaku began to study the basic research of micro wave and basic radar technology, so naval radar program improved to the research and development style. But there was the double appointed problem which Army employed the same specialists. And then, The direction of naval radar program was submitted by Gunrei-Bu (Japanese naval high-ranking officials) using the plan of her military preparedness, so this program was able to be a large scale project. But this program was changed their direction repeatedly because of the war situation and then Japanese naval radar program got weaken gradually.
