This paper shows the actural circumstances of Japanese naval radar and their wartime urgent measures for radar. At the end of war Japanese naval radar was widely spread over. : about 250 land-based radar sites, 100 million yen costs, 30 radar types, 500 radar officers and 10 thousand radar operators. For the purpose of that, Japanese navies took the counter plan from the half time of the war. The main urgent measures of this are as follows. THe first, many young naval officers graduated from university got into the naval radar school which named Fujisawa Kaigun Densoku Gakkou (Naval Radar School) established on September 1944 at Kanagawa Prefecture. The second, the new naval manufacture for radar named Numazu Kaigun Khosho (Navy Yard) established on June 1943 at Shizuoka Prefecture. The third, the radar was designed simply for the purpose of easy carriage, reasonable cost and long time operation. The typical radar was the Mark 1 Model 3 radar which was operating at 150 MHZ, peak power 10 KW. So many radar sites were constructed at pacific coasts of Japan, but there was no radar war with United States because of the Japanese primitive radar.
