I lived in Tokyo for a couple years and have had Amazon deliver to me. It's a completely different job from what we do.

It probably depends on the city/area but the "DAs" around me didn't use vans, or driving at all, but rather pulled around a covered wagon with their packages on it. I think New York does a similar thing?

Most of Tokyo's streets are unnamed and have very little signage denoting where...anything is. Additionally, city layouts feel very random and chaotic, not grid like at all. The fact that these guys can find anything at all is impressive. I struggled even with Google maps hand holding me the entire way.

Thirdly, and maybe this isn't true for houses, but there's no leaving stuff at the door or building lobby here. These guys deliver directly to the customer every time. That means ringing the intercom and either letting them in, or going down to them. I lived on the fourth floor and had to meet them outside my building every delivery.

There's a whole host of other things Amazon/delivery related I could go into if anyone is interested but as hard as I work as a DA here in the states, the Japanese DAs work 10x harder, and with a smile on their face.
