STLASSH

What STLASSH does

STLASSH is a Japanese women-only hair removal salon chain operated by KABUSHIKI KAISHA CLEAR (株式会社クリア), founded in 2015 under the brand philosophy "Start for Lady's Shine." As of January 2026, the company operates 62 stores across all eight Japanese macro-regions (Hokkaido through Kyushu/Okinawa), has accumulated 330,000+ members and 3.14 million+ treatments, and employs approximately 700 staff. The company ranks No.1 in Google review count among major Japanese female depilation chains per two independent 2024-2025 surveys.

The company's core technology is the proprietary ISG Triple Attack method combining SHR (蓄熱式) and IPL (熱破壊式) dual-mode laser hair removal with the ST Super Gel containing 47 skincare ingredients including sheep amnion extract, CICA, and fermented rice extract. The STRIKE hair removal machine-developed in-house and awarded the JAC Beauty Award 2023-adds industry-first electroporation technology that simultaneously delivers skincare ingredients into the dermis during hair removal, marketed as a "non-needle Potenza." A 1000x optical microscope skin diagnosis was introduced in February 2024. Complementary product lines include the HADA TERASU skincare sub-brand (15+ SKUs spanning facial wash, lotions, essences, masks, brightening gel, feminine care wash, and the new RADIANT stem cell cosmetics line), home-use devices HOME STLASSH and HOME STLASSH PRO (IPL with RF attachment, ¥52,425), and the MULTI FACIAL CARE 2-way beauty device.

STLASSH operates a hybrid revenue model: monthly subscription (月額制, from ¥2,980/month), prepaid session packages (回数制), and pay-per-visit (都度払い, with self-service unmanned options from ¥5,000/30 minutes). A new-customer introductory offer of full-body plus VIO three sessions for ¥9,900 anchors acquisition, with conversion into higher-LTV subscriptions. Distribution combines 62 owned salons, a D2C e-commerce store (d2c-store.jp), Yodobashi Camera retail (13 stores as of September 2025), department-store pop-ups, and LINE/web booking. The Advance Payment Guarantee (前払金保証) partnership with Japan Guarantee Co. (subsidiary of J Trust), effective July 2025, is the hair-removal-industry-first consumer-protection system. In October 2024, STLASSH diversified into marriage matchmaking via subsidiary Marry Yell, an IBJ franchise store.
