No e131, Working Papers from Tokyo Center for Economic Research
We examine the trends in cash usage in Japan and its substitution with noncash payment methods, such as credit cards and electronic money, using both aggregate and individual household survey data. We find that cash hoarding accounts for as much as 42% of total cash circulation in Japan. Behind this finding lies an unstable semi-log cash demand function after the late 1990s and a stable log-log cash demand function from 1995 to 2016. We also find that the extent of possible decreases in cash demand because of the substitution of cash for credit cards in day-to-day transactions is not large. Our back-of-the-envelope estimate of the possible maximum decrease in cash demand for day-to-day transactions is at most 0.4% in 2017 of the total cash in circulation in Japan.
