Don’t shrug a sleeping passenger off your shoulder
In the West, sleeping on someone else’s shoulder while riding a bus or train can be awkward for everyone around. If this happens, most of us would shift our bodies to slightly jolt the sleeping person awake. Hopefully, that’ll get them to get their head off our shoulders for at least a few minutes.
But in Japan, you shouldn’t do this. In fact, you’ll be viewed the inconsiderate person for bothering a sleeping person. A day of work in Japan is unlike what most of us experience here. After hours and hours of constantly working, you should understand why the person next to you is resting his or her head on your shoulder.
