What LEC does

LEC, Inc. (レック株式会社, TSE Prime: 7874) is a Tokyo-headquartered, publicly listed Japanese consumer goods manufacturer founded in 1979 (originally as 駿河工業株式会社) and consolidated under its current name in 2009. The company designs, manufactures, and distributes a broad portfolio of household products spanning cleaning supplies (the flagship 激落ちくん/Gekiochikun melamine sponge line since 1999), pest control (バルサン/Varsan insecticides, acquired from Lion Corporation in December 2018), hygiene, baby care (under Anpanman IP licensing), personal care (LecBe), and — following the June 2024 acquisition of the グロンサン and グロモント brands from Taisho Pharmaceutical — nutritional energy drinks and supplements. LEC operates five domestic factories (Shikoku, Shizuoka #1, Chubu, Fuji Susono, and Fujieda Chemical) supporting a 2,000+ SKU catalog and over 1,000 new product launches annually, with proprietary technologies including alkaline electrolyzed water formulations, melamine sponge materials, and patent-pending airlaid hydrolysis paper.

The company's business model rests on multi-channel distribution: a sales-led B2B motion through Japanese home center chains, drug stores, and convenience stores (with dedicated Sales Division 1st and 2nd Headquarters plus an EC Sales Headquarters), complemented by direct-to-consumer sales through its own official online shop (lec-online.com) and storefronts on Amazon Japan, Rakuten, Yahoo! Shopping, Wowma!, auPAY Market, and Qoo10. Pricing is unit-based across a broad CPG catalog. Three wholly-owned subsidiaries (エフティイズ・コンフェクト, プラマイゼロ, 銀座化粧堂) extend operations into confectionery/toys, lifestyle products, and cosmetics, respectively.

In June 2026 LEC announced a strategic extension into AI-powered consumer products via the AI Charmy (アイチャーミー) brand, combining AI conversational character hardware (talking plush toys) with subscription services and content/merchandise, with the first product (Matsuken Version featuring 松平健 IP) scheduled for December 2026 release and planned multilingual overseas expansion. As of FY March 2026, LEC reported consolidated revenue of 682.94 billion yen across 956 consolidated employees, with 42 consecutive periods of revenue growth and recognition as PPIH's 1st Best Partner Award recipient in 2025.
