Power Rangers SPD opening in Japanese, YouTube.
There's a bit of an introduction about the fact that Tokusou Sentai Dekaranger was remade into SPD (I think it said "in America", but I could be wrong), and then the opening credits. The lyrics are still the English-language ones, and each character's name is rendered in katakana (with the exception of Grumm, there's some kanji in there that I can't quite read). No actor names are credited, but I'm sure that they will be somewhere.
Apparently the actors dubbing the series into Japanese are the original Dekaranger actors. Given the differences in the characters, this will be very interesting. (Sen-chan, DekaGreen, is much calmer than his SPD counterpart, for example. And it will be interesting to hear Syd voiced by Umeko's actress.)
