I would imagine its to keep Japanese developers interested in the 360. Although the 360 may not sell well in Japan, a lot of Japanese games sell very well on the 360 in the west. I think I remember MS saying that a substantial amount of the top 5 games on XBLA are Japanese developed (Castlevania:SOTN). Plus some JRPGs have done decently on 360 like Star Ocean the last hope, Tales of Vesperia, Final fantasy, etc. Fighting games like Street fighter, blazblue, king of fighters, etc which are all japanese developed are doing pretty well on the 360 as well.
So overall, MS has a good incentive to keep the 360 atleast somewhat alive in Japan to keep the developers developing games for it.
