Q.ships? Did the Japanese Navy use or consider using them?

From reading commander memories the would surface to use their guns for small craft not worth a torpedo. Seems an oppty. to use a Q.ship.
Every done?

I see one was fitted out and sunk on its first sortie. Delhi Maru.

Not exactly an answer to the question which you asked but possibly related ... Japanese armed merchant cruisers ...

That illustrates the problem with Q Ships.

The British gave up on the idea and completed the last n number of specially designed Flower class Q ships as escorts.

I was thinking Q.ship in WW2 only useful if in very shallow waters as in the area off the Malay Peninsula or a very small vessel which a submarine would not want to use a torpedo. This Q.ship was a torpedo worthy target. Then of course, perhaps by the time it was commissioned the IJN was desperate to use any vessel for ASW. As I read here or somewhere, the Japanese would mount DCs on almost any vessel.
