Props and Weapons Policy

NOTE: These rules were updated on January 24, 2017.

Naka-Kon strives to continue our tradition of being a safe, family-friendly convention! We’d like to provide you with the guidelines for acceptable Props and Weapons, so that we can help you plan your cosplay accordingly!

Prohibited props and weapons consist of, but are not limited to:

  • Metal props that have sharp points or edges (Note: Naka-Kon does not allow peace-bound metal weapons).

  • Ice skates.

  • Props that are not made of metal, but have sharp enough points or edges to cause an injury.

  • Airsoft guns, paintball guns, and other firearms, even if modified.

  • Fake firearms that look similar to real firearms.

  • Crossbows or hunting bows, even if modified.

  • Arrows with sharp points.

  • Smoke machines and strobe lights.

  • Anything that explodes (Firecrackers, Poppers, etc.).

  • Anything that shoots fire.

  • Anything that shoots a projectile (Including, but not limited to Nerf guns, water guns, marshmallow cannons, confetti cannons, etc.).

  • Anything that creates excessive light or noise.

  • Any sort of remote-controlled craft or toy, including drones and RC cars.

As a reminder, firearms (whether open-carry or conceal-and-carry) are not allowed on OPCC, Sheraton or Marriott premises unless carried by a police officer. We would also like to advise you that Naka-Kon, Sheraton Security, OPCC Security, and the Overland Park Police Department will treat anything that looks like a real weapon as if it is a real weapon. In order to ensure the safety of our attendees, we will not allow any weapon if we mistake your prop for a firearm or think someone else might.

Naka-Kon will allow props and weapons such as, but not limited to:

  • Fake projectile guns, such as Nerf guns or T-shirt cannons, that are modified so they can’t fire (Note: Naka-Kon does not allow peace-bound projectile weapons)

  • Wooden swords or bats

  • Metal props with dull points or edges

  • Simple bows, either unstrung with a very loose string that cannot be used to shoot.

Mock Fighting, swinging, brandishing, shooting, throwing, crossing swords, “waving my weapon at my friend”, etc. is not allowed at Naka-Kon. You are welcome to pose for photographs with your prop or weapon, but please refrain from the swinging! That’s how people get hurt! Any misuse of your weapons or props may result in our staffers confiscating it or asking you to remove it from convention space.

If you have a large prop or weapons (longer than 5 feet, heavier than 10 pounds, wider than two feet), please feel free to email with any questions or concerns you have.

Naka-Kon reserves the right to inspect and reinspect any prop or weapon, and to require the removal of any prop or weapon.  If you have any questions about the rules above, please email for clarification. While we will not provide “pre-approval” of props and weapons, we can let you know if something violates one of our rules ahead of time!

The props and weapons rules are subject to modification at the discretion of the Naka-Kon Japanese Cultural Education Association.
