Oh, no. It was never a Japanese thing. Strictly Chinese, because they had the population numbers to "burn through" with nonsense like footbinding. Why? Because every woman reduced by deliberate crippling to being an ornamendal object of her husband, as a demonstration of his wealth, had to have slaves to attend to her every need. Wealthy men would then buy their wives young girls from impoverished families. Since polygamy was the norm, a man had as many lilyfoot wives and stables of slave girls as his wealth would allow.
