Since we have Virtual Earth localized in Japanese and have good imagery and street data in Japan, we figured maybe it would be a good idea to convert the Virtual Earth SDK to Japanese too for developers who prefer the local script. Using the localized version of the Virtual Earth map control is pretty straightforward - you just need to add a parameter for the local language when you reference the map control as such:

Currently, only Japanese is supported in addition to US English.
