Since I am taking daily trips to the local Japan Post Office branch nearly every day to ship packages, I decided to buy a bicycle. Of course, this couldn't be just any bicycle, I had to get an original Japan Post Office delivery bicycle, complete with the bright orange paint and all the decals. I can carry all of my packages on the front and rear racks, which is convenient being that I don't have a car.
Another plus is that I can park the bike anywhere, and the bike wardens don't ticket it or impound it. Not a bad deal for about $100.
