Forget Japan, even JL pilots are losing jobs and going to KE in dozens.
Your information is so utterly wrong that is not even funny, granted they are not the wide body command the op is looking for but, Skymark is hiring by droves, Air Japan is also hiring and NCA should start hiring later this year (these are wide body job of course) also both Air Asia Japan and Peach will tap into the ex pat market for pilots soon.
