It's far more common for foreigners to carry luggage on the trains in my experience. Especially on the subway.

Wouldn't that be a biased view based on the fact that foreigners are the ones more likely to travel?

I did consider that, the other factor is Japanese people travel for smaller periods of time so maybe carry tiny suitcases instead of the (multiple) huge ones you see foreigners carry.
