Uma no Kiroku — Legendary Horse Archive
A visual storytelling app for Japanese horse racing fans that brings the legends of the track — Oguri Cap, Narubi Brian, TM Opera O — to life with rich biographical timelines, race replays, and jockey interview archives.
Japanese keiba fans in their 40s-60s nostalgic for the Showa/Heisei golden era of horse racing
- Biographical timelines for every JRA legendary horse with race footage and trainer/jockey interviews
- Curated 'this week in history' feeds keyed to upcoming G1 race anniversaries
- Lineage maps showing bloodline descendants of fan-favorite horses like Oguri Cap (whose great-grandson Forcap is now a stallion)
The NHK Project X episode on Oguri Cap is reigniting interest in 80s/90s keiba legends, while Oguri Cap's great-grandson Forcap just started his stud career, making the family tree newly relevant.
Project X confirmed revival in April 2025 with Oguri Cap episode '駆けろ!オグリキャップ 奇跡はおこせる', Forcap (ひ孫) retired to stud May 2025 with multi-outlet coverage, and JRA's own page quotes 40代-60代男性 as core fan demographic — real but narrow nostalgic signal.Nhk 新プロジェクトx「駆けろ!オグリキャップ 奇跡はおこせる」の出演者・見逃し動画配信は？ ↗夢とロマンを背負って…あのオグリキャップの「ひ孫」が種牡馬入り ↗
Direct overlap exists: JRA Racing Viewer's '未来に語り継ぎたい名馬' archive already offers Oguri Cap biographical timeline + full race replays for ¥550/月, and the 競馬伝説PRIDE mobile game and oguricap.net also occupy parts of this niche.未来に語り継ぎたい名馬 JRAレーシングビュアー ↗競馬伝説PRIDE on the App Store ↗
Keiba fans demonstrably pay: JRA Racing Viewer ¥550/月, JRA-VAN multi-tier subscriptions, and nostalgic 40-60s male demographic has disposable income — but most Oguri Cap content is freely available on JRA's own site/YouTube, capping premium pricing upside.未来に語り継ぎたい名馬 JRAレーシングビュアー ↗Jra-vanを競馬情報解析ツールとして使いこなす!有料サービスの料金や口コミ評判のまとめ ↗
Oguri Cap has 30+ years of unbroken cultural relevance (1,274-person crowdfunding for bronze statue 20 years post-retirement) and Project X revival confirms Showa/Heisei nostalgia cycle is active, but the niche is inherently bounded by aging fan cohort.未来に語り継ぎたい名馬 JRAレーシングビュアー ↗
Timeline/journal UI is trivial, but race-replay video licensing from JRA and jockey interview archive rights are real legal/contract hurdles; JRA itself already owns and serves the canonical content, making independent acquisition difficult.未来に語り継ぎたい名馬 JRAレーシングビュアー ↗
