When I went to Japan last April (2014), I'd elected to almost solely shoot film instead of digital.
I'd picked up an old Nikon F3HP via KEH, a few rolls of Portra 400 & Fuji 400H, and tucked my X100 away in the bottom of my backpack—to be used in case of emergency. I didn't need it, thankfully.
It's hard to truly describe what Japan is like—another world, almost—and it's not the bright lights and packed trains that contribute to that. It's the people, who are astonishingly polite; the infrastructure, which is impeccably clean; and just the care that a lot of Japanese people seem to have for everything they do.
We stayed in Shinjuku, had ramen at Kyushu Jangara Ramen in Harajuku, visited Shakey's for bad pizza, caught the train to a little mountain town called Miyanoshita and hopped on a bus down to Hakone.
Given more time we'd have caught the bullet train down to Osaka & Kyoto, but they deserve (need!) more than just a day trip—something saved until next time.
