It’s quite historical place for Japanese combative sports from boxing, kickboxing, pro wrestling to MMA. And they host them pretty much daily basis. A cup of beer costs 650 yen, so you might want to get tanked with cheaper alternatives before you come here. The building is wicked, wicked old and not glamorous like watching fights in casinos. Atmosphere is more like watching it at some hall of local PAL(police athletic league). It’s located on 5th floor and definitely quicker to take stairs when you leave during post show exodus. Comparing to other combative sports venue such as Differ Ariake, this venue’s biggest advantage is accessibility. It’s about 5 min walk from JR Suidobashi station. All the shows here are more like«minor league”-ish event. So you probably don’t come here unless someone you know, or someone your friends know happen to be fighting here.
