In a country where vending machines are so abundant, the introduction of new bank notes can have a measurable positive impact on the economy, even though it won't drastically improve the overall economic climate.

According to estimates by Dai-ichi Life Research Institute, the new bills to be put into circulation Nov. 1 will have an economic effect totaling around 1 trillion yen, with 60 percent of it stemming from upgrading existing vending machines and purchasing new ones that can take the new bills.

About 15 percent of the total economic effect will stem from similar needs to modify automated teller machines and cash dispensers, and the remainder from printing the new bills themselves.
