What E-Payment does

E-Payment Co., Ltd. (株式会社イーペイメント), founded on 13 January 2009 and headquartered in Roppongi, Minato-ku, Tokyo, is a privately held Japanese payment processing services provider that targets e-commerce sites and online businesses. The company operates a multi-payment system (マルチ決済システム) that allows a merchant to accept credit cards (VISA, MasterCard, JCB, American Express, Diners), electronic money (Edy, SmartPit, BitCache, G-MONEY and several others), convenience store payments (paper and paperless), bank transfer agency services (including Rakuten Bank, Mitsui Sumitomo and Mizuho), and cash-on-delivery through a single integration. The platform is built in-house, is PCI-DSS Ver 2.0 Level 1 compliant, and is paired with SECOM SSL for in-transit security, plus ISMS (ISO/IEC 27001) and Privacy Mark certifications.

The company monetizes through transaction-based pricing, comprising setup fees (typically 20,000–150,000 yen per payment method), recurring monthly fees (0–20,000 yen) and per-transaction rates or fixed fees that vary by method — for example, 3.5%+ on credit card processing and 8%+ on most e-money rails. Beyond core processing, it offers adjacent operational services including cash-on-delivery fulfillment, logistics management, and Sagawa-integrated warehouse management, positioning itself as an end-to-end EC operations partner rather than a pure payment gateway. The company cites the broadest payment method coverage in Japan and a 3-day implementation window as key differentiators.

Go-to-market is primarily direct sales to EC merchants, supplemented by a channel/agent program that recruits web development and system development firms as resellers earning ongoing commissions on referred merchant volumes. The company also extends services to overseas entities through global payment services. With 11–50 employees, no disclosed external funding, and no listed parent, E-Payment operates as an independent, founder/management-led firm under Representative Director Koichiro Tamura.

Direct peers

• Epsilon (GMO Epsilon): Japanese payment processor focused on online card payments and multi-payment aggregation for EC merchants, now part of the GMO group. Direct competitor in the Japanese multi-payment PSP market, particularly targeting mid-market and content/digital merchants.
• SBI Payment Service: Japanese PSP offering multi-payment processing for online merchants, including cards, e-money, and convenience store payments. Direct peer competing for the same mid-market EC merchant segment with comparable product breadth.
• GMO Payment Gateway: Japan's largest online payment processor, offering multi-payment aggregation across cards, e-money, konbini payments, bank transfers, and COD for EC merchants. Directly competes with E-Payment across the same customer base of Japanese e-commerce sites, with broader scale, more extensive developer tooling, and deeper enterprise merchant penetration.
• Veritrans (DG Financial Technology): Major Japanese PSP providing multi-payment processing for EC merchants, including cards, e-money, bank transfers, and convenience store payments under a unified API. Directly comparable to E-Payment in product breadth and target market, but with significantly larger transaction volume and stronger brand recognition.
• Rakuten Payment: Rakuten group PSP offering online payment processing for EC merchants in Japan, including credit cards, bank transfers, and Rakuten Pay. Direct competitor in the same Japanese multi-payment aggregation category, with strong brand association and bundled merchant services from the Rakuten ecosystem.

Broad incumbents

• Stripe (Japan): Global payment platform with significant presence in Japan, offering developer-first APIs, card processing, and a growing range of local payment methods. Competes with E-Payment for Japanese EC merchants but with global scale, stronger developer brand, and limited support for legacy Japanese APMs such as konbini payments and COD.
• PayPal Japan: Global digital payments platform operating in Japan, offering online payment acceptance for EC merchants alongside PayPal wallet and cross-border capabilities. Competes with E-Payment for Japanese EC merchant volume but with a different value proposition oriented to international buyers and wallet payments.
• Digital Garage: Japanese fintech group operating payment processing (including via subsidiary Veritrans) and broader commerce enablement services for EC merchants. Comparable to E-Payment in payment processing overlap, but operates at substantially larger scale with diversified marketing and platform businesses.
• Adyen Japan: Global unified commerce PSP with operations in Japan, providing card and local payment method processing for enterprise merchants. Competes with E-Payment for Japanese enterprise EC volume with a unified global platform, but with limited focus on Japan's legacy APMs such as konbini payments and COD.

Emerging players

• Net Protections (NP後払い): Japanese deferred payment provider specializing in post-pay (後払い) and COD-style settlement for EC merchants, including logistics integration. Comparable to E-Payment's COD offering and overlapping on the konbini/cash-on-delivery payment segments, but focused specifically on post-pay risk management rather than full multi-payment aggregation.
