Also, I didn't see a reference to Sega World Tomakomai on Retro (except for this thread). There is a mention of it here in Amusement Sangyō on the NDL website announcing its opening and dated 1997 March, though it's not available digitally. I get the impression that there was both a Sega World and a Sonic Bowl opened, being in separate buildings, with Sonic Bowl located here. Or maybe not, maybe it was only the Sonic Bowl with Sega World as a "subtitle." There is a Dinospark basically right across the street from it which is listed as officially using Sega prize machines, but not sure if there's any connection. edit: Derp, I guess the Tomakomai location is already listed on the Todo page for Venues. I missed that.
