> White rice has one of the highest glycemic indexes.

This is correct, but do keep in mind the impact that cooling down has on starches.

A fresh bowl of rice is very high, but cool it for a couple of hours and the GI drops considerably.

Cool it overnight and it drops even more. Onigiri is usually in the cooled down to over-night range.

This never makes rice particularly good from a GI perspective, but preparation is a considerable factor.
