What did people in Japan use as shaving soap/aftershave back when they were secluding themselves? Did they make shaving soap like we use now or did they do something else? I was reading Shogun by James Clavell (an interesting book, though I'm informed it isn't entirely accurate) and the main character, a European, remarks that during his time in Japan he got accustomed to shaving every day, though he mentions nothing of the actual process. Anybody know?
