Yup, plenty o' cons
Yes, there are cons. They have a convention in Seoul every other month. There is one in April, not one in may, and then one in June, I believe. The months that they are not in Seoul, they are down Busan, which is wayyyyy south. Its not a whole lot like state side cons, but they are fun and way less expensive. The seoul convention is about 5 dollars to get in and all of the trade stuff to buy is usually custom made by all the artists. The Costuming is different also, but well prepared by all the cosplayers. I hope this helps. Just email me if you need any more info, I plan on going to the next few ones, so just email me.
