There are some places that don't really take kindly to people taking pictures, and unfortunately these are often places of the more interesting variety. Games centres definitely fall into this category, for reasons which I haven't been able to work out. I managed to do a covert shoot in the big Sega game centre on Dogenzaka the other night, and was able to document some of the action that was going down. I stayed away from the (well monitored) print club booths, and tried to get some good pictures of the more elaborate virtual-reality games. As an interesting postscript, while this centre is open until midnight, children under 16 are not allowed in after 6pm..
