IsshoCon is a convention sponsored by the owners of Otaku Detroit, a small business dedicated to all things anime and Japanese culture. Their customers have always mentioned to us starting another anime convention in Michigan. With their tremendous support they were able to host their very first single-day anime convention at Beer Middle School in Warren. Since then, their mini conventions have only continued to grow and thus IsshoCon was born. A convention for Otaku Detroit's community of customers to all come together and have some fun!
