Probably best known for its eponymous beer, Sapporo—the capital of Hokkaido, Japan’s northernmost island—has maintained the youthful and open atmosphere of the 1972 Olympic Winter Games, drawing international visitors for its annual Snow Festival and its world-famous ramen. Those seeking out the full diversity of Japanese cuisine will want to visit: a city with a ramen-inspired theme park is one that embraces and pampers foodies.
