KADOMA, Osaka Pref. -- Chocolate eggs are an integral part of Easter celebrations in the West. Although they have yet to catch on in Japan, one particular egg-shaped variety has become a hit here.

The success of Choco Egg, priced at 150 yen each, stems not from the popularity of the chocolate itself but from what can be found inside them -- a miniature figure in the shape of an animal, fish, bird or insect.

The figures -- produced by Kaiyodo, an Osaka-based company -- come in nearly 100 different varieties and are said to be so lifelike one expects them to start moving.
