A fissure of excitement spread among my student friends in the 1970s when a film fanzine reported that the actor Helen Mirren sported a tiny tattoo on the sole of her foot. Four decades later, a similar fizz rippled through Japan when it was revealed that Caroline Kennedy, U.S. ambassador to the country from 2013 to 2017, sported two tattoos, one visible -- a small butterfly under her right elbow. Would she be admitted to Japan's notoriously conservative hot springs, swimming pools and gyms, we wondered?
