It's not only the type rating mate. The JCAB requires Air Law, Radio Law, and several other tick the box items, even when you come across with an ATP. That in itself takes a month. Then the company training starts followed by another month of CBT - then the over 10 flat panel sims, and 17 simulator sessions for the type rating. Once you finally achieve the type rating - wait for it - another 6 sims for the ATP conversion. That's at the 6 month mark. Once that's completed you do a medical, and English exam (another tick the box JCAB) then you get home for 9 days. Returning to NRT you attend another 3 weeks of ground school, route FAM stuff, then do 3 more sims, then do line training, which brings you to at least another 2 months, thus totalling roughly 8 months with 9 days at home - though I must add several days off in Tokyo in between Sims/groundschool.
