Everything IN the kitchen sink?

When I was in Tokyo with my sister and my friend Matt, we went and ate out at a real nice restaurtant in Harajuku. This is a picture of what-I-thought-was the urinal. So, I did my business, zipped up, and then needed to wash my hands. Well, there was no sink in the bathroom, just the toilet and some liquid soap next to the "urinal." Well, it turns out that the "urinal" was a sink. Whoops...cultural miscue #1. Doesn't it kinda look like a urinal though?
