What netkeiba does

netkeiba is Japan's largest horse racing information portal, operated by privately held Net Dreamers Co., Ltd. (株式会社ネットドリーマーズ) and founded in 1999. The platform aggregates JRA (central) and NAR (local) race schedules, odds, results, expert columns, news, video programming, and a proprietary database of more than 500,000 racehorses searchable by bloodline. It also operates adjacent products including netkeirin (keirin cycling betting and information), netkeiba Owners (racehorse ownership and co-ownership management), netkeibaTV (original video), and a horse breeding/racing simulation game (Umairu Stadium), reaching approximately 17 million monthly users and 1.5 billion monthly page views across web, iOS, and Android.

The platform is built on a freemium content-plus-subscription model. Free access covers news, race results, basic predictions, and community forums, while paid tiers (Master Course, Super Premium Course, Premium Course, with monthly and annual billing) unlock pro predictions, full race video streaming, digital racing newspapers, and 30-second real-time speed reports. A 14-day free trial supports conversion. Additional monetization layers include advertising against the platform's demographic-skewed audience, e-commerce merchandise (including TRACK CITY apparel and limited pop-up exclusives), transaction fees from keirin betting, and subscription tools for racehorse owners. Distribution spans the official site, iOS and Android apps, RSS feeds, official X/YouTube/Instagram accounts, and recurring physical pop-up stores.

netkeiba's customer base consists primarily of Japanese horse racing and keirin enthusiasts (skewed toward males aged 20-50 with disposable income), supplemented by racehorse co-owners and corporate advertising clients. Strategic positioning emphasizes category leadership through AI-assisted predictions, content depth, and ecosystem extension into adjacent racing verticals, sports media (via co-operation of Weekly Baseball Online), and Japanese pop-culture collaborations.
