Earlier this month, South Korea's GungHo held a, well, GungHo Festival in Tokyo. The event also saw the Ragnarok Online Japan Championship—so there was that, too!
Ragnarok Online is a South Korean MMORGP that has a sizable following in Japan and throughout the world.
Kotaku Japan was on hand for the festivities, the costumes, and the man nipples. You've been warned!
