Our Japanese & Redmond team have been working together and just released the Japanese version of Web Deployment Projects for Visual Studio 2008... Our Japanese friends have been patiently waiting for this release since the December 2007 CTP of WDP 2008 was released, so finally this RTW will help unblock a lot of people...
