If left on its own devices and if it lucks out on getting treatment? A very long time (for them). But since this is 9th's work as long as the next schmuck character can get his jollies from the suffering of this extremely unusual and probably non-yukkuri nitori (seriously? actual solid rice?).
Edit:
If this nitori is not attacked and left on its own, it should live up to adulthood considering how packed and non-runny the rice filling is.
Of course it should not be possible for this nitori to move considering how packed the rice filling is as it could not conceivably undulate its body like any semi-liquid filling yukkuri. In short, 9th is not even trying to make his stories more believable in the context of how yukkuris should move and could move without floating on air.

i know of no pastry that is capable of moving so i think rice is as good as any other filling

What makes you even think they are actually pastries? They may taste like pastries but are they really pastries? Do pastries rationalize their existence or communicate or procreate? The typical yukkuri liquidy filling makes it possible for them to jiggle and deflate a lot more easily than they would if they were made of a stiffer filling like sticky rice. 9th's nitori is several magnitudes more absurd than the typical depiction.
