PayPay Corp., a SoftBank Group Corp. firm, said it chose South Korea in its outward debut as the neighboring country was the most popular overseas destination among Japanese travelers and cashless payment is prevalent there, making it easier to gain cooperation from local merchants.

"We hope to further expand PayPay use abroad in places popular with Japanese tourists," such as Taiwan, Hawaii and China, said Masayoshi Yanase, head of the finance business strategy division of PayPay, which now has over 70 million users.

Rather than this being a service for Koreans, they are taking the Chinese strategy of forcing national payment systems on other country’s infrastructure. Not a fan of this approach to exporting black boxes offshore.
