Vista launched in Japan just over 19 months ago. Coincidentally, I was in Tokyo at the time and wrote about the launch on my old blog where I noted a serious advertising blitz (along with every electronic store breaking the release date by a full week.)

XP still dominates Japan

Based on a previous survey from March of 2007 which showed XP with 78 percent of the market and other Windows version with about 14 percent, it looks like Vista hasn’t so much replaced XP as it has the legacy Windows versions in Japan.

Nearly two years later, Vista has 24 percent of the market. Since we don’t know what the expectations were, it’s hard to know if this is good or bad. I suspect it’s not great based on the survey data that shows 90 percent of those surveyed said they came to use Vista because it was bundled with a new PC.
