Toilets in train stations.

In Japan, trains are the primary mode of transportation, and you're likely to hop on one during your travels. Purchasing tickets from the vending machines and passing through the ticket gates is the usual routine. However, here's a handy tip: most Japanese train stations only have restrooms inside the ticketed area. So, if you need to use the facilities at the station, remember that you'll need an entry ticket. Also, once you exit through the ticket gates, you won't be able to reenter, so be extra cautious in such situations! Stay prepared and enjoy your train journey in Japan!
