Japanese cruisers and the limits of anti-submarine work

Japan was developing equipment comparable to ASDIC, but it was not initially widespread and cruisers were not used heavily for anti-submarine warfare.

Question

Did Japanese cruisers have an ASDIC-like system for anti-submarine warfare?

Short answer

Japan was developing similar equipment, but it was not initially widespread and cruisers saw limited anti-submarine use.

Notes

Japan was developing equipment comparable to ASDIC, but it did not appear to be in widespread initial use. Japanese cruisers were also not employed heavily in anti-submarine warfare. Later provisions for depth charges therefore look more like another assigned possibility than a mature core mission. Carrying anti-submarine equipment did not by itself create an effective fleet-wide detection and employment system.
