It's FIVE !!
←How much is this?
"Five". We say at least twice a day.
Because this coin doesn't express in figures, it is difficult for our guests to figure out.
It seems that foreigners don't use small coins such as ones and fives
and that's why their purses look heavy all the time.
Some people say that they are pointless, but now you know how much it is,
don't hesitate to use them :)
