... surely they can make quarter repeater, but we, Japanese, count numbers with the unit of 10. We are really not familiar with the concept of quarter. We don't have 25 yen coin. Just 1, 5, 10, 50, 100, and 500 yen coins. Also, something interesting to note is that we don't use 20 in the money. We have 1000, 5000, 10,000 yen bills. Truth be told - there is 2000 yen bill introduced 10 or 15 years ago - there was a big fuss in the banking and vending machine industry to accommodate such "odd" amount bill. But then, soon after, nobody uses 2000 yen bills.
Anyway, if you could afford, you can surely order quarter repeater and there you will have it.
