Stephen, you just made me realize that I am really very unobservant. I worked in Shinjuku on and off for a little while, alternating between Tokyo and Kamakura (interesting commute for a gaijin). Would you believe, I never noticed that you could see Fuji-san from Shinjuku?!
I'm not sure about this particular picture, but I really like the yakitori restaurant photo on your blog. Totally captures the atmosphere. Along those lines, have you seen anything by a local photographer named Junku Nishimura? Here's one that came to mind
when I was looking at your shot. A little grittier, but I wouldn't hesitate to guess where either one was taken.
