Hi Maria,
Greetings from Japan! It’s (your name) We’re staying in a five star hotel! There are lots of things to do. In the mornings my classmates and I walk through the markets to try and get the best bargain! In the evenings we go to a sumo wrestler event! Right now I am writing you this post card at the hotel pool. My friend Allie says Hello. We’re all having fun! See you soon.
Your friend, (your name)
