What to pack for a year in Japan. (Backpacking)

Tomorrow I fly out to Japan for a year of walking across the country.

You might be wondering—what do you even need for a year like that? Honestly, I have no clue. This is just my attempt at figuring it out.

I’ve never been backpacking. I’ve never moved from place to place every few days. And I’ve definitely never walked this much—unless you count the treadmill at the gym.

The first problem I ran into was my backpack. It doesn’t fit my torso properly, but it’s too late to replace it now. I also couldn’t find a water bottle that fit in the front pocket once the bag was full, so I ended up special-ordering one that’s about the thickness of a Red Bull can.

Everything else? I just did some research and made my best guess.
