• About 18.5 percent of Japanese households said they use electronic money, such as smartphone apps and debit card payments
• Prime Minister Shinzo Abe is pushing to make more Japanese switch to cashless payments

Almost a fifth of Japanese households use electronic money for small purchases, a survey by a central bank-affiliated research institute showed, up from a year ago and a sign the country’s cash-hoarding culture is changing.

In the survey published on Monday and conducted between June and July, 18.5 percent of households said they use electronic money, such as smartphone apps and debit card payments, on shopping trips where ¥1,000 ($9.17) or less is spent, up from 15.4 percent in the previous year.

Among single-person households — 43 percent of whom are in their 20s and 30s — the ratio was much higher at 35.6 percent, suggesting government efforts to prod Japanese to go cashless may be paying off, at least among the younger generation.

Despite the growth in electronic payments, Japan’s “cash-is-king” mentality remains entrenched with the survey showing 84 percent still use notes and coins for small purchases.

And for payments exceeding ¥10,000 and up to ¥50,000, 48.5 percent of households said they pay by cash and 3.4 percent by electronic money, the survey showed.

A low crime rate, years of ultra-low interest rates and a nationwide network of automatic-teller machines (ATMs) have long made cash appealing in Japan, giving people few reasons to shift to cashless payments.

Prime Minister Shinzo Abe is pushing to make more Japanese switch to cashless payments to allow stores to automate sales estimates and banks to cut back on costly ATMs.

Shoppers have recently been encouraged to ditch cash for e-money after the government introduced a rebate program to ease the pain of a sales tax hike on Oct. 1.
