In a Kyoto restaurant (the type where you leave your shoes and use slippers to go to your table), I encountered an upright cabinet, glowing with blue light from within. What now, was that? Even after years, Japanese electric appliances continue to surprise and amaze me. Noticing my puzzled look, a colleague inquired with me whether these were not common in other countries? No, really, we do not have electric slipper disinfectors, in fact this was the first I ever laid eyes upon. Of course, we have less need to disinfect large numbers of slippers in public use. Japanese cleanliness is as always admirable, and to have an electric appliance take care of the problem with UV light, well, nothing less of the Japanese!
