Tea Please

This teacup and saucer is from my husband’s mother’s collection of cups from around the globe. Her friends at the hospital would travel and bring her a cup and saucer from their trip. I’m not sure if it’s from Japan or China. There’s 2 marks on the bottom of the saucer, one of which looks like this ((. The numbers 225 or 220. It’s so difficult to tell.
