The Japanese Project K3, No.1-class Submarine Chaser No.1 was completed in March 1934 as a part of the Maru 1 Programme. It was the first class of the dedicated Anti-Submarine Warfare vessels in the Imperial Japanese Navy. The major advantage of the vessel was its high speed, while the key issue was a problem with the strength of the hull, which was later addressed in refits, modification of the No.3 subclass before it was built and finally, fully resolved in the No.4-class. She spent most of her service in the southern seas, survived the war without any notable successes, and finally was scuttled by the Royal Navy off Singapore.

The Type K-3 No.1 was introduced in Update 1.89 "Imperial Navy". The ship has a powerful and varied combination of weapons, as well as good survivability compared to the other vessels in her BR. Her main disadvantages come from being such a large vessel - she has a low manoeuvrability and is easy to hit with nearly anything, from bombs and rockets to artillery strikes.
