For some reason I just remembered a simple little puzzle I was told about ages ago, so I thought I’d try it out here.
On certain trains in Japan, passengers are not allowed to enter a compartment with any piece of luggage which is too long or too wide to be placed in the overhead racks; any parcel or package with dimensions larger than 60 cm × 80 cm is forbidden. It is possible however to enter the carriage with a metre-long samurai sword.
How?
