Light fleet carriers in an invasion of Japan

How did the Royal Navy plan to use light fleet carriers if Japan had to be invaded?

They would accompany the Americans and provide air support for landings, particularly as larger fleet carriers rotated away.

Light carriers would provide mobile air support for an Allied invasion of Japan. The campaign might develop from more than one direction, with Allied landing craft later transporting Soviet forces after captured ports allowed merchant shipping to sustain the initial lodgment. Carrier employment was therefore tied to the wider logistics and coalition sequencing of Operation Downfall. The light carriers' particular value would be persistent support near the landing forces while larger fleet carriers rotated away or returned home.
