It’s been a while since I shot a roll of film on my Leica. It was browsing through the wonderful book of photographs of travels throughout Asia in the 1990s (and 1980s?) called Asia Grace by Kevin Kelly and John Sypal’s Zuisha (随写) that did it.
When you think of big Japanese cities I doubt that mountain biking comes to mind. But if you know where to look even in the major urban sprawls you’ll be able to find potential trails.
