Two Very Different Meanings

ぺこぺこ (pekopeko) is a fascinating word with two distinct meanings. As a gijougo (擬情語), it most commonly describes the feeling of being extremely hungry — your stomach is empty and practically caving in. But it also works as a visual description of someone bowing repeatedly, bobbing their head up and down in a servile manner.

Gijougo words capture feelings and emotional states. The “hungry” meaning of ぺこぺこ perfectly captures that hollow, desperate feeling when your stomach is completely empty — it’s more vivid than simply saying 「お腹が空いた」(I’m hungry).

The Hunger Connection

「お腹がぺこぺこ」 is one of the first casual expressions Japanese learners pick up, and for good reason — it’s far more expressive than the textbook 「お腹が空きました」. The word ぺこぺこ suggests your stomach is so empty it’s practically collapsing inward, making a hollow “peko peko” sound. It’s casual, fun, and immediately understood.

Fun Fact

The bowing meaning of ぺこぺこ carries a slightly negative nuance — it implies excessive, sycophantic bowing rather than respectful greeting. Saying someone is ぺこぺこしている suggests they’re being a pushover or trying too hard to please authority figures. It’s the difference between a sincere bow and a nervous, repeated head-bob.
