The massive number of saleswomen at a typical J-department store can't be missed, but what's more astonishing is the legion of flunkies, toadies, flops, and other species of oyaji working behind the scenes. It's amazing that the paradigm has survived for as long as it has; huge public subsidies are doubtless involved.
I'm not sure that the demise of the current bloated incarnation of the J-department store would be a bad thing. They have the effect of snuffing out small businesses in whatever retail ecosystem they're located, which is more often than not a train station since so many of them are owned by rail operators.
