Thanks everyone for your help! I do have to store the bike outside; I live in a tiny apartment in Japan and the bike is outside my door. The only thing protecting it from the elements is a vinyl bike cover. It flops around in the wind and moisture blows in under it. Violent storms blow the whole cover off.
The bike is only a year old, so I'm surprised parts of it are rusting already.
Here's a pic of the whole bike:
I recently put on Nitto Campee racks; unfortunately, they are not compatible with my bike. This is the thread I created about this issue:
