There are a lot of buses running throughout Tokorozawa. I was riding this Seibu bus the other day. Most of the buses here don't have any steps and the button you press when you want to get off at the next bus-stop is just about everywhere.
I'm always afraid I'll lean on it and press it by mistake. And am I the only one who gets nervous about pressing that button? I'm always relieved when someone gets off at the same stop, so I won't have to press it :)
