oprel The « Comiket building », in other words, Tokyo Big Sight is a pretty good guess and one I should think about for a future quiz! As far as I know, no video game company has ever had it’s headquarters there. However, the building you see above was not too far away (it does not exist anymore). I think on a clear day, from the top floor, there is a decent chance you could see the Tokyo Big Sight from this building.
