Kids got a close look inside the Bank of Japan on Monday.

26 children from 4th to 6th grade toured the Bank of Japan headquarters in Tokyo.

There, the children learned about technology used for counterfeit prevention.

They also discovered how much a 100-million yen weighs.

Bank of Japan Governor Haruhiko Kuroda stopped by to say hello.

He told the children that some of them could become the future business leaders of the country.
