In 1982, I visited Japan for the very first time. Among the places I went to on that trip are ones that I've re-visited, such as Tokyo, Kyoto, Osaka, Fukuoka and the Aso Caldera. But I've yet to return to the Japanese city which may well have left the deepest impression of the trip on me: Nagasaki, one of the two cities in the country which will forever be associated with the atom bomb.
