The Japanese division of Tesla Motors has today opened a store for its electric vehicles in Tokyo.

Up until today, the US-based group has been selling its Roadster elctric car via the Internet in Japan. Japanese giant Toyota has invested significant sums in Tesla

"The Roadster was born in Silicon Valley, but, in a sense, it is a Japanese car," said Elon Musk, CEO of Tesla Motors. "Its battery cells, which are the heart of the vehicle, are made by Panasonic."

Earlier in October Tesla Motors entered into a Phase 1 Contract Services Agreement with Toyota Motor Corporation for the development of a validated powertrain system, including battery, power electronics module, motor, gearbox and associated software, which will be integrated into an electric vehicle version of the RAV4.

Based on preliminary specifications, TMC will pay Tesla approximately US$60m for the development services to be provided by Tesla.
