Prop weapons of any kind are not allowed on the festival grounds at the Johnson County Community College during the Greater Kansas City Japan Festival. This includes plastic swords, knives, or other weapons including those used for Cosplay. If a festival volunteer observes any attendee carrying such a prop, they will be asked to take the prop off the festival grounds immediately.

The only exception will be prop weapons used by entrants in the Cosplay contest. These props may not be carried around the festival grounds during the day and may only be used during the Cosplay contest. Prop weapons used in the Cosplay contest must be carried directly backstage to the Polsky Theatre just prior to the Cosplay contest from 6:15-6:30pm. The Cosplay contest will be held from 6:30pm-7pm in Polsky Theatre. After the contest, the props must be removed from the festival grounds.

Weapons purchased at the festival must immediately be taken off festival grounds.

Failure to adhere to this policy in a timely manner will be lead to the attendee being escorted by Johnson County Community College Campus Security off the festival grounds with the possibility of not being allowed re-entry nor refund.

Cosplay literally means Costume Play. It is a performance art in which participants (cosplayers) dress up and pretend to be fictional characters (usually sci-fi, comic book, or anime characters). The rapid growth in the number of people cosplaying as a hobby since 1990 has made the phenomenon a significant aspect of pop culture. Cosplay events are common features of fan conventions and there are also dedicated conventions, local and international competitions, as well as social networks, websites and other forms of media centered on cosplay activities.
