What Istyle does

Istyle (株式会社アイスタイル, TYO: 3660) is a Tokyo-headquartered, publicly listed beauty platform company founded in 1999 that operates @cosme, Japan's largest cosmetics and beauty media site. The company runs a vertically integrated stack spanning consumer media (@cosme), e-commerce (@cosme SHOPPING), and physical retail (@cosme STORE chain plus flagship stores in Tokyo, Osaka, Nagoya, and Hong Kong), with a B2B layer (@cosme for BUSINESS / 4biz, ISDC data consulting, and the newly launched @cosme Copilot AI assistant) that sells advertising, marketing solutions, and data-driven consulting to cosmetics brands. The platform serves 16.7M+ monthly visitors and houses 22.3M+ cumulative reviews across 46,000+ brands and 420,000+ products, accumulated over 25+ years.

Istyle's core technology is its proprietary cosmetics database and the AI/analytics layer built on top of it, including @cosme Copilot (launched January 2026) for review analysis and brand insight generation, KAORIUM AI fragrance profiling (deployed via SCENTMATIC at @cosme HONG KONG), and RNA-based skin-type diagnosis via the @cosme consortium partnership demonstrated at CEATEC 2025. The B2B stack is wired together with marketing automation (HubSpot), BI (Tableau), and SFA tools under THE MODEL sales framework, supported by a CTO-led "Reborn" modernization of legacy systems that have accreted since the platform's founding.

Istyle makes money through a hybrid model: advertising on the @cosme media platform, transaction and commission fees from @cosme SHOPPING, hardware/retail sales through 36+ @cosme STORES and international flagships, and a growing professional services and SaaS book from B2B marketing solutions, ISDC consulting, and AI subscriptions (marketing solutions segment alone posted ¥2.8B operating profit for the year ended June 2025). Management's stated medium-term target is ¥100B in revenue and ¥8B in operating profit, supported by domestic expansion (Kyoto in October 2026), international flagship rollout in East Asia, owned-brand growth (tilnus, @cosme+), and AI-driven B2B monetization.
