Can't figure out what is going on - I'd think/hope that maybe Japan was going to open up but I've seen nothing that indicates that and anyway doubt the airlines would be the first to know.
The cancellations/reductions are all listed on the JAL website. Right now the reductions are announced until end of May, so from June what you will see if you try to book is really the full pre pandemic schedule. Yesterday (24th) JAL added Manila, Sydney, Hanoi, and Hi Chi Minh flights for March. So even once the reductions are announced, adjustments can happen. I guess right now we will see additions rather than further reductions.
What flights are you looking at?
