Vending machines are ubiquitous in Japan.
Mostly they’re selling drinks: water, chilled tea and coffee, sodas, beer and ‘whisky highballs’. And some stuff that remains mysterious.
Sometimes they’re selling snacks and ice creams. Very occasionally cigarettes.
They take coins, notes and the also ubiquitous IC card. Cheap, easy, convenient, reliable.
The walk from our apartment in Miami-Fukuoka to the train station was maybe all of 100 metres, and it went past seven vending machines.
