The Daiban is a monetary unit from Japan's old era, its origins can be traced back to the Edo period. At this time, Japan's currency was still very unstable, and there were various types of currency in circulation. In order to unify it, the Edo shogunate prescribed a new currency unit - the Daibon. Daiban was mainly used as a currency for tax payments and commercial transactions. Due to its liquidity and convenience, it soon became the main currency of the Edo period.

In addition to the Edo period, Daiban also appeared in other periods. For example, during the Meiji period, Japan began to carry out Western-style reforms. Due to the large demand for currency, the government began to print daikan. During the Showa period, the Daiban was gradually phased out and the Japanese yen was used instead. Today, the yen is the legal currency of Japan, and the daiban has become a historical cultural relic, but there are still many collectors and museums that collect daiban.

Dafan is not just a monetary unit, it also has rich cultural connotations. It can be seen from the design and wording of daiban that daiban is usually printed with patterns that symbolize Japanese culture such as paper cranes, Mount Fuji, and cherry blossoms. These have become a unique cultural phenomenon in Japan during the period when daiban was used. At the same time, daiban also has high artistic value. Many famous paintings and sculptures also use daiban as the theme, and it has become an important part of Japanese culture.
