Did the Japanese have Hedghogs?

Magnitic Anomaly Device (MAD) was also used by the allies. It was deployed on the USN's PBM series of patrol flying boats. The USN also deployed airborne radar in the search of German subs.

this was taken by Wiki

Magnetic anomaly detectors employed to detect submarines during World War II harnessed the fluxgate magnetometer, an inexpensive and easy to use technology developed in the 1930s by Victor Vacquier of Gulf Oil for finding ore deposits.[2][3] MAD gear was used by both Japanese and U.S. anti-submarine forces, either towed by ship or mounted in aircraft to detect shallow submerged enemy submarines. The Japanese called the technology jikitanchiki (磁気探知機, "Magnetic Detector"). After the war, the U.S. Navy continued to develop MAD gear as a parallel development with sonar detection technologies.

So it isn't a leap to believe that the Japanese used a similar devices

Many thanks for that research and by the by (belatedly, along with Armistead) welcome aboard Cowboy 40

Good historical research is the absolute foundation of better mods and realism in our fervent pastime here at Subsim!

One often overlooked item in the Japanese ASW inventory is the Kabaya Ka-1 gyrocopter. Probably the first instance in history of such a craft being used for this purpose although they were originally developed for artillery spotting. However, there no recorded cases of any of them tangling with a US sub.

They had side launchers for depth charges as well.

Apparently, some of the older Japanese destroyers started the war without DC racks, but they were quickly installed.
