A super-fun tradition that has developed in Japan is the Bento box lunch. These are given to schoolchildren as their lunchboxes, or taken by families and adults for picnics. Bento is a variety of small foods packed in special Bento boxes, most of them arranged as picture art. The ones for children are especially delightful--a whole scene, such as a train running along a track with the sun shining, is made up all of food. This is a whole new set of foods and recipes. Here are some links--have fun! My 13yo daughter loves making these.

Cooking Cute
Some fun bento foods my daughter, Julia, has made are boiled eggs decorated to look like chicks or bunnies or chicks hatching, oniguri rice balls surrounding something inside, like a piece of carrot, and little octopi, squid and crabs carved from hot dogs.
