Cheapest coffee in Japan
A regular cup of coffee is not the most affordable drink in Japan: coffee shops will charge you around 300-500 yen per cup. (2,5-4 euro).
If you need a quick morning or afternoon fix without expecting barista quality, get your coffee in a conbini (コンビニ)or convenience store: Lawson, Seven Eleven, Family Mart, Newdays.
They cost 100-150 yen and the quality is equal to those offered in coffee shops like Beck’s Coffee, Doutor or Tully’s, where they normally cost around 300-400 yen per cup. Usually it’s self service with a cup-to-go.
My favourite is Lawson’s own brand Machi Cafe.
