Hello Donna,

Having lived myself for several years in Japan, I can tell you that it is sometimes hard to get to Japan, but the loads are in general better in Januari/Feb. Also please keep in mind that flights to japan are under strict weight restrictions, which means that for example when a flight still has many empty seats, does not mean that the Airline will accept Non-revs as there may be lots of Cargo on the Plane; or maybe weather related conditions. Off course you never know for sure what happens.

Regards,
AMS
