Some cities in Japan have large underground pedestrian tunnel systems, too. In Tokyo, the most extensive might be around Shinjuku Station [1], though there’s also a large one around Tokyo Station that is connected through a series of tunnels to a smaller one around Yurakucho and Ginza [2]. I walked the entire length of the latter one snowy day about twenty-five years ago. Fukuoka and Sapporo also have underground passageways and malls in the city center. My favorite is the maze of tunnels in the Umeda area of Osaka [3]. It includes a lot of retail as well as sometimes obscure connections through the basements of buildings. The bar- and restaurant-lined corridors under the slightly rundown Osaka Eki Mae buildings are especially fun to explore [4, 5].
