hmm what is Bento actually?
Bento can be elaborately arranged in a style called "kyaraben" ("character bento"). Kyaraben are typically decorated to look like popular characters from Japanese cartoons (anime), comic books (manga), or video games. Another popular bento style is "oekakiben" or "picture bento". This is decorated to look like people, animals, buildings and monuments, or items such as flowers and plants. Contests are often held where bento arrangers compete for the most aesthetically pleasing arrangements.
There are similar forms of boxed lunches in the Philippines (Baon), Korea (Dosirak), Taiwan (Biandang), and India (Tiffin). Also, Hawaiian culture has adopted localized versions of bento featuring local tastes after over a century of Japanese influence in the islands.
