What is "omake"

n. A special video feature that accompanies an anime, such as a collection of deleted scenes or outtakes.

means extra in Japanese. Its primary meaning is general and widespread. It is used as an anime and manga fandom term to mean "extra or bonus". In the USA, the term is most often used in a narrow sense by anime fans to describe special features on DVD releases: deleted scenes, interviews with the actors, "the making of" documentary clips, outtakes, amusing bloopers, and so forth. However, this use of the term actually predates the DVD medium by several years. For at least the past 50 years in Japan, omake of small character figurines and toys have been giveaways that come with soft drinks and candy and sometimes the omake is more desired than the product being sold.

In English, the term is often used with this meaning, although it generally only applies to features included with anime, tokusatsu, and occasionally manga. It is thus generally limited to use amongst fans of Japanese pop culture (sometimes called otaku); like many loan words from Japanese, omake is both the singular and plural form.
