As a 1k, I see availability July 2-4, 6-8, 13-15 NRT-LAX. Some coach, some business.

After I sign out, I see about the same availability. 85k miles gets you First to LAX via HNL on 13th. On the 14th, 35k miles gets you coach to LAX via HNL

Not sure why you can't see them. Are you just looking for non-stops? If so, maybe that's the problem. Why don't you grab an award with a connection, then watch for something you like better?
