Cosplay & Props Convention Rules

We are quite well aware about the new Texas law pertaining open carry swords and knives. We are allowed by Texas State Law and HBG venue rules to ban open carry of any kind of firearm, knife or sword within the convention space. There will be signage posted at the convention.
Anyone caught within San Japan convention space walking around with a metal sword or knife will be ejected from the convention. Please read our cosplay rules below for more information.

Here are our current Cosplay Prop Rules.

Basic Dress Code

  1. Please use good judgment and common sense in general. This is a family friendly convention. Keep all costumes sensible and at a rating acceptable in public. There will be children present.
  2. No costume is no costume! If you are not clothed properly, you will be asked to change. This includes having a shirt and shoes at all times. We are using public spaces we rent so the local laws are in effect. No shirt, no shoes, no service. For costumes which a character is typically shirt-less, all MALE costumes may remove their shirt for photos but must put the shirt back on when walking in public spaces.
  3. Please make sure your costume uses non-see through material over the private body parts. Once again remember there will be children present.
  4. No profanity displayed on the clothing or costume.
  5. Those who abuse this policy will be subject to removal from the convention without refund from the convention or the Hotel.
  6. Remember you will also be walking through public areas such as the River walk, Rivercenter Mall, and non-convention hotel spaces. How you act and represent yourself will reflect upon the convention as well.
  7. Grossly offensive or high shock value cosplays, uniforms, outfits or t-shirts will be asked to change or risk expulsion.
  8. For potential safety issues you would like to bring up, please use our contact form.
