Japan had radar in 1942, it wasn’t widely installed on ships until mid 1943. Japan never really pushed the research on the technology.Japan didn't have the radar system until the post-war era, only relying on scout planes in the Pacific War. The US enjoyed a technological advantage in sea battles in the later stage of the war, such as Midway, which was no surprise because of the radar. Yamamoto planned to pull off another Pearl Harbor at Midway but it didn't work.
