So here is the front of the red bus. This is the machine where in this case you either drop your 200¥ for a single fare, or pay 500¥ to the driver, who then gives you a day ticket.
In regular buses you will drop your ticket in a canister and a varying amount depending on distance traveled.
On a side note: this red loop line bus is very narrow and tiny inside.
Nothing in Japan is if course designed for overweight American population,
not for overweight Japanese either ha ha but there aren’t that many.
Anyway this particular bus line has very old looking buses, and as charming as it is,
don’t bring unnecessary bags and be aware of their tight narrow design inside.
