What is tsumicon?

As an AI language model, I do not have access to current information about Tsumicon, but I can tell you that a few years ago, Tsumicon was a convention dedicated to the popular Japanese mobile game "Disney Tsum Tsum." The convention featured merchandise vendors, game tournaments, cosplay contests, and meet-and-greets with the game's characters. Tsumicon also hosted panels and workshops for fans to learn more about the game and its creator, the Japanese company LINE Corporation. However, it is important to note that this information might be outdated now.
