Merchant acquiring sits under the Installment Sales Act (for card acquiring) combined with the PSA for wallet/funds-transfer services; merchants typically partner with FSA-licensed PSPs or domestic bank acquirers. Onboarding is rigorous, with detailed KYC, business-model scrutiny, AML transaction monitoring and STR filing to the FSA/National Police Agency. Certain sectors (gambling beyond government lotteries, adult content, crypto) face restrictions or extra permits. Asset-light acquiring and gateway models (GMO Payment Gateway, PayPay merchant subsidies) shape competition.

Merchant Acquiring & Risk
Merchant acquiring sits under the Installment Sales Act (card acquiring) plus the PSA (wallet/funds-transfer). Merchants partner with FSA-licensed PSPs or domestic bank acquirers under detailed KYC, business-model scrutiny, AML monitoring and STR filing to the FSA and National Police Agency. Restricted sectors include unlicensed gambling, adult content and unauthorised financial products; foreign PSPs generally require a local subsidiary or partnership. The FSA is tightening fund-segregation rules under the PSA, forcing wallet operators to restructure capital reserves. The local-establishment requirement and tightening fund-segregation raise the barrier and capital cost for foreign acquirers and wallet operators across bank and non-bank channels. This is an under-indexed surface: chargeback dynamics, high-risk MCC treatment, acquirer stress and interchange regulation lack primary evidence, and the module rests on vendor summaries, capped at Assessed.
Outlook
The acquiring regime is stable in structure, with the live pressure point being tightening fund-segregation rules that force wallet operators to restructure capital reserves. Merchant-acquiring operations remain a methodology-flagged under-indexed surface for the jurisdiction, warranting deeper primary-source coverage.
