Station Stores
Here's a photo of your average "Station Store",
things you can buy are;

klenex, razors, batteries, energy bars, energy drinks
tea, coffee, gum, deodorant, batteries ,cigarettes
magazines, newspapers, maps, beer, and vodka,
sunflower seeds, dried fruit, chocolate bars, stomach medicine, water
juices, and buns. I myself usually buy either beer or the English newspaper - sometimes a chocolate bar at these corner "stops".
Very very convenient!
All within 2 feet from buying your tickets to get on the train,
service is fast and dependable - no one in Tokyo can live without them.
