What does 紙芝居 Kamishibai mean?

Kamishibai means paper theater: a story performed while illustrated cards are presented in sequence. The pictures are part of a telling, not merely pages handed to someone to read.

The compound

紙芝居 combines 紙 (kami), paper, with 芝居 (shibai), a play or drama. Wiktionary records the readings kami, shiba and i across the three characters. 芝居 functions as the theater word in this compound; treating its separate characters as objects in the story would not explain the term.

This is a noun for a performance form. It is neither slang nor a name for a particular age group, and the word by itself specifies no genre of story.

Who sees the words?

The Japan Society's 2019 teaching resource explains a practical distinction from the children's books used in its classroom comparison: text is on the reverse of the cards, allowing the teller to read while the audience sees the pictures. Its authors are Fergus McNicol and Mio Shudo, with Laura Boddy as editor.

That arrangement divides the task. The listener does not need to see the script to follow the image and the spoken performance. The performer determines when the next picture is revealed. A transcript alone would omit that timing; a stack of pictures alone would omit the delivery.

A format that carries stories

The same resource lists picture-card versions of Momotaro and The Moon Princess among its materials. These are examples of stories presented through the form, not competing definitions of it. Its classroom use also shows why paper theater should not be treated solely as an obsolete object.

Manga and kamishibai both use sequences of pictures, but that shared feature does not make them interchangeable. For an anime reference, the question is whether the work invokes this performance arrangement. A series of still drawings, by itself, does not establish it.
