I think the old scheme was much better than the new one. That doesn't mean it should not have been changed though, but I think it was not yet crying for change, if you ask me.
The new logo looks bad, like a regional bank or something, just one in a sea of other similar logos that you normally see on Japanese streets. That strange boomerang, as someone pointed out, and the font, which looks at least outdated. The red-sun tail looks no better, especially side-by-side with the new NWA livery (which was in fact introduced later, but which definitely has got that something in it).
Finally, I believe that the new livery is around for less than a year, but I may be wrong. A year at most, as I recall.
Just a thought. Yes, I know, I will probably get used to it anyway.
P.S.: Not to mention, that now JAL, JAA and JTA look all the same (the tails used to be different earlier). JAA was nothing special, but I quite liked the JTA sunset tail fin.
