Companies Using A8.net

I expected A8.net to look like a Japanese AWIN when I pulled it from our October 2026 crawl: brands running a network's tag. It turned out to be both sides at once. A domain counts when it loads A8.net's sales tag from statics.a8.net, which advertisers install to record conversions, or shows an image from an a8.net host, which is how publishers' banners and links load. The total is 7,693 live domains, 511 matched to a company, 11th of 96 in Affiliate & Referral. FAN Communications runs it, per A8.net's English about page, which lists 27,420 advertisers and 3,736,646 publishers.

Half advertisers, half bloggers

I opened a random sample of 70 A8.net domains in a browser. 35 carried publisher banners or links, 25 the advertiser sales tag, one had both, and 4 were dead STORES shop pages. Our request logs point the other way, 2,853 domains calling statics.a8.net against 670 calling banner hosts, because banner images often load lazily and never fire while we crawl. So the count is split, with publishers slightly ahead. The company list isn't: bloggers rarely match a company record, so 38 of the 50 companies we checked showed the advertiser tag.

Two clusters are one company each. 495 dead STORES shop pages load STORES' own A8.net tag on a shared 404 template, and we left them out of every chart. 38 domains show Parallels' page title, such as switchtomac.org, one advertiser's aliases.

Sales signal: an A8.net detection on a company domain is almost always an advertiser paying for performance marketing in Japan. On a personal blog it's a publisher. Split the list before you write a single email.

Steady after the summer

The chart reads 5,818 in June, 7,150 in July, 7,415 in August, 7,470 in September and 7,693 in October. The June to July step is mostly our side: the domains we crawl turn over every month, with dead sites leaving and new ones arriving, and our detection signals widen. From July to October the line rises 543 domains. Since March 2026, 846 domains have dropped A8.net, and about 70 of them still run it on another hostname.

"A8.net is the rare network where the advertiser and the blogger show up in the same count. Treat them as two lists." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: a stable base of about 7,700 domains. The advertiser roster is the useful part, so spend your time there.

The advertisers are established Japanese brands

Among matched companies with a known size, 36.89% have 1 to 10 employees, 25.06% have 11 to 50 and 23.2% have 51 to 200. 23 list more than 1,000 staff, and they're household names: JR Central on its e-mono shopping site, JVCKENWOOD on its online store, TV Asahi on its video service, Yakult on its cosmetics shop, Kitamura on its photobook service, and KOSÉ. Age points the same way, with 32.75% founded before 2000. Many big advertisers run the tag on one site rather than the corporate domain, because that's where the sale happens. They pay for the privilege: A8.net's fee page lists a ¥50,000 set-up fee, ¥40,000 to ¥50,000 a month and a 30% commission on every publisher payout, while publishers join free, per its FAQ.

Sales signal: A8.net advertisers already pay for every sign-up and sale. Conversion tracking, landing-page and attribution tools fit, and the buyer is a performance-marketing team, not IT.

Japan first, and services more than shops

Japan is 356 of the 465 matched companies in the top 15 countries, 76.6%. The United States has 62, and most foreign names sell into Japan, such as Immerse, Bossjob and QEEQ. IT Services and IT Consulting leads the industries at 8.6%, then Retail at 8.31%. Software, education and recruitment fill the list: freee, Smaregi and SourceNext; PROGRIT, atama plus and Global Step Academy; AXIS Agent and Remedy. The Facilities Services row (4.87%) is a labelling quirk; Sakura Internet, Yahoo Japan and Club Tourism carry it.

Sales signal: pitch A8.net advertisers on lead quality and sign-up economics. Subscription software, schools and recruiters pay per lead, and they care about cancellations.

Two networks on one site

We don't publish switching rows for A8.net; none pass our tests. Japanese affiliate sites stack networks. 1,744 domains run A8.net and Moshimo today, out of 1,975 ever seen with both, and 995 run A8.net and ValueCommerce, out of 1,134. Bloggers join several networks to carry the same advertiser at the best rate, and advertisers often list with more than one.

"In Japan nobody leaves A8.net for ValueCommerce. They add the second network and keep the first." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: multi-network publishers need link management and reporting across ASPs. That's the gap in this stack.

The stack: WordPress blogs and Japanese ad tools

Across the 7,339 domains we kept, WordPress runs on 63.76%, Google Tag Manager on 82.4% and Google Analytics on 83.57%. AdSense is on 38.08% and Twitter Ads on 23.61%, with Japanese ad tools behind them: Yahoo Advertising 16.23%, Intimate Merger 11.36% and the Yahoo! JAPAN Tag 2.44%. Quantcast Measure shows on 18.56%. On Moshimo's domains we traced that signal to the Cocoon theme's prefetch list, so it marks Cocoon blogs, the publisher half. Microsoft Advertising is on 10.55%.

Sales signal: advertisers here buy search and social ads alongside affiliate. Cross-channel attribution has an audience.

Key takeaways

1. 7,693 live domains, 11th of 96 in Affiliate & Referral with 2.43%, just behind ValueCommerce.
2. The count holds both sides; in a random sample, 35 publishers to 25 advertisers.
3. 495 dead STORES shop pages carry one tag; the charts use 7,339 domains without them.
4. The named companies are advertisers, many large and old: JR Central, JVCKENWOOD, TV Asahi, KOSÉ.
5. Networks stack in Japan: 1,744 domains run A8.net and Moshimo, 995 A8.net and ValueCommerce.

Sales applications

Outreach template: "Your site runs A8.net's sales tag, so you already pay publishers per sign-up. We help Japanese performance teams cut the cancellations that eat into that spend."

Targeting: on TechnologyChecker.io, filter A8.net domains to companies with more than 50 staff in Japan; that leaves advertisers. Filter to WordPress sites without a company match for publishers.

Competitive angle: the 995 domains on both A8.net and ValueCommerce are comparing networks already, the natural audience for multi-network tracking.
