We know that one of the funnest parts of attending a convention or event is cosplay. We want all attendees, both cosplayers and non-cosplayers, to attend safely and enjoy the cosplay element of J Con. To allow this, we have some specific guidelines and rules regarding cosplay:

  1. As mentioned above, J Con attendees are of all ages. Costumes must have a minimum coverage of modest swimwear. Anyone whose costume is deemed offensive or too revealing will be asked to cover up or leave the event.
  2. The content or look of costumes must also be suitable for all ages. Anyone who fails to adhere to this will be asked to leave immediately.
  3. All attendees must wear suitable footwear. Bare feet, rollerblades/quads or heelies are not permitted. If you plan to wear shoes that might cause your feet to ache after some time, please bring a change of shoes to relax in.
  4. If you plan to wear head gear that makes it difficult to see properly, or if your costume restricts movement, you must bring a buddy who can help you to move around.
  5. Although we welcome all costumes, please keep in mind that the event may become a little crowded and be mindful or the space available. Large armour, wings, swords, tails etc may not be suitable as space is limited. Please make sure that other attendees can walk past you without problem.


  1. Props will be checked at the entrance of the event to ensure safety. As mentioned above, all props must be suitable for an event that is attended by a large group of people. Anything deemed too dangerous will be confiscated until you leave the event. Props must break before people.
  2. Props may be carried around, but please take extra care if they are large or cumbersome. If you are bringing a prop specifically to use as part of the Cosplay Contest, please store it in a suitable place until the contest begins.
  3. Any attendee, cosplayer or otherwise, who misuses a prop, for eg intimidating other attendees, making threatening actions, dangerous horseplay etc will be asked to leave the event immediately.
  4. Airsoft guns are allowed but must be made of plastic, must be unloaded and no air inside. Airsoft guns made from metal will not be permitted.


  1. Any harrasment towards cosplayers will not be tolerated. Anyone who harasses or offends a cosplay in any way will be asked to leave the event immediately. This includes but is not limited to verbal abuse, physical and or sexual misconduct.
  2. If you wish to take a photo or recording of any kind with a cosplayer, you MUST ASK PERMISSION FIRST. Any cosplayer or other attendee has the right to refuse this permission without reason, if they so wish.


A Note To Parents:

This is a message for parents and guardians who might be wondering what this whole J Con thing is about. Perhaps your child/children or their friends want to go, but you have never heard of this stuff before and you want to know a little about what is involved.

The easiest way to see what J Con is like, is probably to watch this video of J Con last year: https://www.youtube.com/watch?v=iSGyv9yxgSM

Attendees are generally interested in some or all of the following (explanations attached to help you understand!)

anime – Japanese animation/cartoons

manga – Japanese comic books

cosplay – short for “costume play”, i.e. dressing up as your favorite anime, manga, cartoon or movie character. Attendees either buy a ready made costume, make the costume by themselves, or a mix of the two. Some go to great lengths to make a “realistic” costume, and the results can be truly incredible.

Computer games

Board games

Generally being a geek and enjoying it

But you don’t have to go dressed up, and plenty of attendees are more interested in the Marvel/DC world of America, than the Pokemon/Gundam world of Japan. It’s all good.

So people go to the event, and when they get there the main aim is to have a lot of fun. There is a whole range of stalls selling items like drawings, paintings, photos, small snacks, figurines, and memorabilia. Most people check it all out and meet the makers, and maybe buy one or two things.

There are talks and presentations (“panels”) given by special guests and fans, about a whole range of topics. These kinds of talks have a large element of Q&A and are often given by fans, which gives the event a really interactive feel. J Con is also hosting some quirky events and competitions which will be a lot of fun.

The main event of any Con is probably the “Cosplay Contest/Masquerade”. Basically, any attendee wearing a cosplay is free to join a fashion show where they get on stage and strut their stuff. Maybe give a dance or some kind of performance.

While these type of events, or “Cons” as they are called, are mainly attended by 16 to 25-year-olds, they are family friendly. Cons are attracting a diverse age range more and more, and recent events in Ireland probably have attendees from 3 to 63. Just attending for a look around and to see the other attendees in their cosplay is a great spectacle and lots of fun.

There is a 50/50 split between guys and girls, and as is outlined in the J Con Rules, the event is open, friendly, and doesn’t tolerate any kind of discrimination.

Lastly, J Con also has a large focus on traditional Japanese culture, and there will be everything from calligraphy and flower arrangement to martial arts and learning the Japanese language. So anyone interested in Japan and its culture will get a kick out of it!

We hope this gives you a little idea of what it is all about. If you have any questions, please check out our FAQ, the other parts of our website, or contact us.
