So after we amassed all these onigiri from the konbini (Japanese convenience store, of which there are more than 40,000 in Japan o_O), we eagerly tore through the wrappers like the barbarians that we are. Only to discover, many onigiris later, that there is actually a super ingenious METHOD to unwrap these triangular morsels delicately. The reason why the triangular onigiri is wrapped as such is so that the seaweed does not touch the rice and so is kept crisp and fresh until you unwrap it. The instructions are actually at the bottom of the wrapper; but who looks at the bottom anyway when one just needs to sink one’s teeth into seaweed and rice immediately?
So, for the uninformed and clueless, here is a step-by-step guide on how to unwrap your konbini-bought triangular onigiri. Enjoy ;).
