Interesting historical find.what years were these active in Japan?And are these style of games still around?I didn't see anything
Like it in the game centers in Akihabara the 3 times I was there.so are they actual arcade machines,or pachinko?I noticed
Some risqué stuff like this on Pachinko machines though.

Either way,Thanks to 9JCHyhd83hks for uploading thse latest vintage Japan finds.
