Further to the above: https://ja.wikipedia.org/wiki/筑紫野ベレッサ It appears the Sega World opened along with the building, "Chikushino Tokyu" (筑紫野とうきゅう). It was closed at the end of March 2006 (I think) and then re-opened in 2007 as "Chikushino Belleza". Apparently it was built to cater for some new housing in the area, but was squeezed by bigger/better rivals. This was the state just before closure - the Sega World would have been on the left, but I think they'd long gone at this point. Judging by the photos it looks like a horrible fever dream. Some Sega Worlds are true works of art, this one... not so much.
