Kyaraben

Kyaraben or charaben (キャラ弁), a shortened form of character bento (キャラクター弁当), is a style of elaborately arranged bento (Japanese boxed lunch) which features food decorated to look like people, characters from popular media, animals, and plants. Japanese homemakers often spend time devising their families' meals, including their boxed lunches.

Originally, a decorated bento was intended to interest children in their food and to encourage a wider range of eating habits. It has now evolved into a cultural symbol, to the point where national contests are held.

In popular culture
Kyaraben lunchboxes are a major plot element in Bento Monogatari, a 2010 short film by Belgian director Pieter Dirkx.
