I'm going to take a trip to Japan this March, and I'm interested in flying from Tokyo to Aomori.

The only problem is that the regular fares are SO high and the Yokoso (Welcome to Japan) Campaign which offers 10,000 yen one-way tickets is not offered at the end of March.

Does anyone have any hints about finding any cheaper fares? Any advice is appreciated.

(BTW, JAL is the only airline that flies to Aomori since ANA and Skymark have pulled out.)
