Some interesting news has surfaced for the Japanese dub of Transformers Animated, courtesy of Livejournal user toriaki. First of all, we have news on the Japanese dub's theme song, which will be sung by the one and only JAM Project! JAM Project is made up of several well-known vocalists including Masaaki Endoh and Hironobu Kageyama, the latter of whom has previously provided the opening, ending and insert songs to Japanese Transformers series The Headmasters and Beast Wars Metals.
On the side of voice actors, toriaki's post also confirms who will be voicing Optimus Prime, Bumblebee, Sari and Megatron in the Japanese dub of Transformers Animated. Optimus Prime will be voiced by Hiroki Takahashi, whose previous Transformers voice credits include Hellscream and Mantis in Beast Wars Second, plus Gildo and Build Hurricane in Car Robots (Japanese Robots in Disguise).
Mr Takahashi is also known for providing the Japanese voice of Street Fighter's Ryu in Street Fighter IV and Tatsunako VS Capcom. Bumblebee meanwhile will be voiced by Daisuke Kishio, who previously voiced Kicker in Transformers Super Link (Japanese Transformers Energon), while Sari will be voiced by Satomi Akesaka. Saving the best for last, we have the legendary Norio Wakamoto playing Megatron.
Mr Wakamoto has previously provided the voice of Flame Convoy in Transformers Galaxy Force (Japanese Transformers Cybertron) and is recognizable as the voice of anime villains everywhere. His most notable credits include Cell in the Japanese dub of Dragonball Z, and providing the Japanese voice of Vega (M Bison) in many of Capcom's Street Fighter titles.
Also mentioned in the livejournal posting is that the DVD / Blu Ray of Transformers Animated will be released in Japan starting in Fall 2010.
