Counting change back in Japan?

Question:

Someone told me that change was counted back differently in Japan and the US. She said here in the US, it's counted up and that confused her at first when she moved here. How is it counted back in Japan? Is it counted starting at cash given and moving down to cost of item?

Answer:

I heard that counting change was difference in US and Jpn.
In Jpn counting change is count back style.
In US, counting change is count up style.

E.G

Store staff: Total amount is Usd345.

Customer:Ok, I'll pass Usd100 x 4=Usd400.

Store staff: Usd400 minus Usd345=Usd55. The counting change is Usd55.

This is Japan style.
Almost Japanese can calculate in my brain without caliculator.

> Is it counted starting at cash given and moving down to cost of item?

Yes that is correct.
