Weapons & Prop Policy


ALL WEAPONS must be inspected and approved by Security prior to being carried or displayed in public areas. If you are found to be in violation of this policy, you will be asked to take it back to your hotel room or vehicle. If there are continued violations with the same prop, your weapon will be confiscated and you may be ejected from the convention.

Props carried in public areas must be no more than 72 inches/6 feet in length. This is for the safety of all con goers, as well as to prevent damage to personal property. If your prop is larger than 72 inches/6 feet, please do not bring it into public areas. Props larger than 72” total must break down into pieces no larger than 72” while on the convention floor. You may assemble them for photos, if you are completely out of the flow of traffic and there is room to do so.

Projectile weapons are limited to the following (*upon inspection by security):

  • water guns
  • cap guns
  • Airsoft guns
  • Replica firearms

The following projectile weapons are NOT permitted at Ohayocon:

  • Dart guns
  • BB guns
  • Crossbows
  • Real firearms

Artificial and replica guns will be permitted, pending inspection by Security, only if they meet the following criteria:

  • they have no clips or moving parts
  • they have a non-removable orange safety tip

No live steel (edged metal weapons) will be permitted. Bladed replica weapons must be made of a non-metal, non-sharp material, must be no more than 72 inches in length, and must be approved by Security.

Commercial weapon replicas purchased in the dealer room must remain peace-bonded/wrapped at all times, and must be taken directly to your hotel room or car after purchase. They may not be carried around the convention. If you are seen carrying a non-compliant weapon in convention areas, it will be confiscated and held by Security until the end of the convention.

Props & Accessories Policy
  • If you are using an oversized prop for a special event, such as for purposes of demonstration in a panel, you may have the prop approved by Security for temporary use in those areas ONLY. The prop must be returned to your hotel room or car immediately when the event is over. If it is part of your Masquerade entry, please alert the Cosplay staff and explain what the prop is and its use at check-in. The Cosplay staff will issue you a pass — however, you may not wander the convention floor with the prop. The pass will permit the transport of the prop to your judging appointment/hotel room/Masquerade ONLY!
  • Metal props may not be carried in public areas. This applies to any large props and weapons, as well as small hand props such as shuriken, fans, wrenches or other items. Metal is permitted on the costume itself, provided it extends no more than 2 inches from the body in any direction, is in no way sharp, and does not present a safety hazard, as determined by convention staff.
  • Use caution when carrying or displaying large props. If you are seen wielding a large prop in a reckless or dangerous manner, your prop may be confiscated.
  • If convention staff feel that your prop poses a risk to others, you will be asked to remove the item from public areas, or it may be confiscated.
Prohibited Materials
  • Inflammable materials such as candles, fireworks, sparklers, liquid fuels or other fire hazards are strictly prohibited. Small personal smoking paraphernalia (cigarettes, lighter, etc.) may be carried, but may not be used in public convention areas.
  • Your costume should not shed. Please avoid loose materials such as sand, glitter, confetti, flower petals or other items that are designed to fall, scatter or otherwise separate from your costume.
Signs Policy
  • Signs are not permitted unless they are an intrinsic part of your character’s costume. Personal message signs, fandom signs (such as “Will Glomp For Pocky,” “Free Hugs”, etc.) and similar non-cosplay-specific signs are prohibited.
  • Clothing that displays messages deemed to be inappropriate or offensive to others (including, but not limited to, explicit language, sexually suggestive or racially offensive material) will not be permitted. Convention staff reserve the right to ask attendees to change or cover offensive clothing. Failure to comply will result in your badge being confiscated.

For the safety of all please observe the following:

  • Ohayocon Staff & Security will have the final approval on questionable props, & weapons. Approved items will be tagged and you will be permitted to carry the item.
  • If not approved, you will be asked to remove it from the convention premises. Attendees MUST take such items immediately to their hotel room or off convention property.
  • Ohayocon Staff is not able to pre-approve weapons and props before the convention. A determination can only be made after actually handling and inspecting the object in question.
