Merchant decision question
A merchant entering Japan wants to compare a developer-facing PSP route with a large domestic payment-gateway route before contacting sales.
When KOMOJU may fit
Prioritize for discovery when the merchant wants to validate a Japan checkout route with public merchant contact paths and developer documentation.
When GMO Payment Gateway may fit
Prioritize for discovery when the merchant wants to qualify a major Japan domestic gateway route and confirm onboarding through GMO Payment Gateway's official inquiry path.
What to verify before integration
- Which Japan payment methods are available for the merchant's entity, product category, and checkout language requirements?
- What documents, contracting flow, bank-account setup, and operational contacts are needed before production access?
- How are refunds, chargebacks, partial captures, fraud review, and reconciliation exports handled?
- Which API, hosted checkout, plugin, and support options match the merchant's engineering capacity?

Do not treat country coverage or brand support as proof that a specific merchant entity, industry, payout currency, or settlement workflow is available.
Public sources to verify
Review notes
- Do not assume Japanese local method support without provider confirmation.
- Do not publish fee, payout, or approval claims from secondary sources.
- Confirm language, contracting, and operational support expectations before integration planning.
