Today is a national holiday in Japan: Coming of Age Day (seijin no hi). This is a day to commemorate all those who will turn 20 years old this year, the age of majority in Japan, when former minors can vote, drink and smoke -- although not particularly in that order. There are many elaborate celebrations wearing traditional clothing. At least, somewhere that's happening. In my town tonight I heard raucous laughter on the street, a most un-Japanese happening. So I went out on the street and watched a mob of just-20s and soon-to-be-20s carrying on. Clearly some of them were jumping the gun on the use of alcoholic beverages.
