Ok let me go in order...
1. LittleBigPlanet is a western IP. That alone means sales expectations should be set very very low.
2. Vita install base is tiny in Japan. Cut those sales forecast even further.
3. Cutesy doesn't necessarily translate into sales. Anyway Japan is more into artistic/manga style games than "cutesy".
4. I doubt Sony even marketed it at all over there. Waste of money.
