today, after one week, i finally managed to outsmart the vending machine to give me plain, hot, sugar-free coffee. i tried so many combinations but always ended up with some variation on ice/sugar/milk coffee.
in nearly every street corner there's a vending machine with hot coffee in cans. have yet to find a brand without sugar in them. the machine i mastered is in the basement of iamas. a coffee there is 80yen ≈ €0,48 ≈ 4,5sek
