What A8.net does

A8.net is Japan's largest affiliate marketing service provider (ASP), operating as a two-sided marketplace that connects advertisers with media publishers — including website owners, bloggers, and social media (SNS) operators — who earn performance-based commissions when their audiences complete advertiser-defined actions such as purchases or sign-ups. The service is operated by FAN Communications, Inc., a publicly traded company on the Tokyo Stock Exchange Prime market (stock code 2461), and has been active for 26 years since its founding in 2000. The platform is free for both sides of the market, with revenue generated through commissions on affiliate transactions.

The underlying technology centers on a cookie-based tracking system that assigns unique IDs to media members and attributes conversions across advertiser websites, with ITP (Intelligent Tracking Prevention) compatibility for Safari users. The platform is delivered through a self-service web console (media-console.a8.net for publishers, adv-console.a8.net for advertisers), supported by a mobile application (A8app), the Selfback self-affiliate feature, and a structured educational ecosystem called A8 Campus offering courses, seminars, and tutorials. The platform holds Privacy Mark certification from JIPDEC for personal information protection.

A8.net serves primarily individual content creators, bloggers, and SNS operators on the media side, and corporate advertisers on the demand side. As of July 2, 2026, the platform reports 27,164 cumulative advertisers, 3,687,310 registered media sites, and 4,512 active advertising programs. The company has held the No.1 position in affiliate satisfaction rankings for 16 consecutive years (2010-2026) according to the Japan Affiliate Marketing Association. Operations are entirely domestic to Japan, with no disclosed international expansion, and the company maintains 101-250 employees.

Broad incumbents

• Awin: Awin is a global affiliate network operating across Europe, Americas, and APAC with cross-border campaign support. It competes with A8.net for advertisers with international presence and offers an enterprise alternative to Japan-only ASPs.
• Rakuten Advertising: Rakuten Advertising is the global affiliate-marketing arm of Rakuten, offering an enterprise-grade affiliate network with international reach. It competes with A8.net in Japan while serving a broader advertiser portfolio across multiple geographies and ad-tech capabilities.
• CJ Affiliate (CJ Marketing): CJ Affiliate is one of the world's largest affiliate networks (formerly Commission Junction), serving global enterprise advertisers with cross-border campaign capabilities. It competes with A8.net for advertisers seeking international reach and enterprise integrations.

Direct peers

• ValueCommerce: ValueCommerce is one of Japan's largest affiliate service providers, directly competing with A8.net for both advertisers and publishers in the Japanese ASP market. It is owned by Yahoo Japan / LY Corporation and offers a comparable commission-based affiliate network.
• Access Trade: Access Trade is a Japanese affiliate network operated by Crossfinity, providing performance-based affiliate programs across e-commerce and finance verticals. It directly competes with A8.net in the Japan-only ASP category.
• Moshimo Affiliate (もしも): Moshimo is a Japanese affiliate network offering an Amazon-focused cashback-style affiliate program and broader ASP services. It competes directly with A8.net for budget-conscious advertisers and consumer-facing publishers, particularly through self-purchase rebate mechanics similar to A8's Selfback.
• AffiliateB (afb): afb is a Japan-focused affiliate network operated by Havas Affiliate Business, directly competing with A8.net for advertisers and female-lifestyle-oriented publishers. Comparable in scale and self-service model within the Japanese ASP segment.

Emerging players

• PartnerStack: PartnerStack is a SaaS-focused partner management platform for B2B affiliate and referral programs. It represents an emerging, technology-forward competitor to traditional ASPs, particularly relevant as A8.net seeks to attract SaaS advertisers.
• impact.com: impact.com is a global SaaS-native partnership management platform covering affiliate, influencer, and B2B partnerships. It is an emerging competitor encroaching on traditional ASP territory with API-first technology and enterprise-grade tooling that A8.net's self-serve model cannot match.
• Amazon Associates: Amazon Associates is Amazon's in-house affiliate program with the largest single-retailer publisher base globally. It is a partial competitor in Japan for retail publishers, and its scale can divert long-tail affiliate activity away from multi-advertiser ASPs like A8.net.
