Japanese currency spans back centuries, with the earliest coins dating back to the late 7th and early 8th centuries AD. The earliest coins were oval shaped or round, with square-shaped holes in the center, and inscriptions were in Chinese characters. During the Edo period (1603-1867), rectangular and round coins known as Edo-sen were issued for everyday use. In the Meiji period (1868-1912), new designs were introduced featuring western-style images. Today, Japan's modern currency includes coins of 1, 5, 10, 50, 100, and 500 yen, along with banknotes of 1,000, 2,000, 5,000, and 10,000 yen
