Japanese fighter direction at the Philippine Sea

How did Japanese carrier fighter control compare with the Royal Navy's system?

Japan had the outline of a control system, but weak radar, communications, and experience caused it to break down and left much of the practical coordination to pilots in the air.

Japan had doctrine and planned fighter positions, but radar coverage, voice communications, trained controllers, and pilot experience were not strong enough to make the system dependable. Procedures that looked workable on paper often broke down in action, leaving pilots to organize much of the defense themselves. The IJN remained well behind British practice and the improving American system.
