Why did Japanese publishers save the Vita?

I wouldn't say they "saved" the Vita, but they helped it a lot. If it wasn't for them, Vita would be selling like the 360 right now. I think they gave it a chance because it was the perfect platform to realize their niche games. Notice how big japanese games, like MH, FF, DQ, Yokai Watch, etc. never appeared on Vita.

360 numbers? This is impossible for a Japanese console! 

I meant worldwide. :p Because if the Vita sold in Japan how it's selling in NA, its WW numbers would be similar to what the 360 pulls these days.
