I’ve got a very special phrase for you — one you’ll be able to use in a TON of situations you come across while in Japan.
Are you ready? It’s not as hard as you think, but is so useful:
kore o hitotsu kudasai
It means “one of this please.”
Use this phrase when you can point at something you want. Perhaps you’re holding a restaurant menu or at a glass counter.
Point at the item you want to order and say “kore o hitotsu kudasai”.
