I'd say...
+ Rodimus Convoy - he seems to be remembered more fondly amongst Japanese fans than Rodimus Prime. I find there's more resentment against Anglophone fans toward Rodimus.
+ Wheelie - not widely liked but certainly not widely despised in Japan as he is in Anglophone fans. The fact that Wheelie doesn't speak in stupid rhymes in Japanese probably helps.
+ Chromedome.
+ Holy - way more popular than Stakeout.

..and that's pretty much it without including Japanese-exclusive characters, who would obviously be more popular since they were never released in Anglophone markets.

Dai Atlas is a notorious character though - kinda like Wheelie amongst Anglophone fans, Dai Atlas is a character who is widely disliked by Japanese fans. I'm sure I've explained the reasons why before, but for anyone who doesn't know why, it's because a lot of Japanese fans strongly resent Dai Atlas' moral universe which is very different from that of Optimus Prime and other Autobot commanders.

Autobot leaders tend to follow the example of Optimus Prime in being very compassionate and merciful. Dai Atlas on the other hand is utterly ruthless against Decepticons - he takes no prisoners and will gladly slay his enemies. He's a very controversial character amongst Japanese Transfans... that and Akira whom JP fans love to debate over whether s/he is a boy or a girl (it's like FIRRIB/RIRFIB in terms of being one of those stupid neverending fan debates ).
