That was IJN's prime doctrine, in response of the American's War Plan Orange, and was opposed by a newer generation of admirals like Yamamoto Isoroku and Inoue Narumi, who saw potentials on naval aviation.

Basicly it's:

1. suppress enemy by subs

2. suppress by carriers, repeat 1 and 2 a few times.

3. Night battle by cruisers on the night right before Kantai Kessen (Decisive Fleet battle)

4. suppress again by carriers on the morning of Kantai Kessen

5. Kantai Kessen by battleships.

But after Pearl Harbor, the Americans discarded War Plan Orange, so the 9-stage doctrine was pretty much useless.
