KOIZUMI

What KOIZUMI does

KOIZUMI (legal name: Koizumi Seiki Corporation / 小泉成器株式会社) is a privately held Japanese home appliance manufacturer and distributor headquartered in Osaka, Japan, founded in 1989 as a spin-off from Koizumi Sangyo Corporation. The company operates a unique dual "Maker & Vendor" business model consisting of two interlocking revenue streams: (1) in-house planning, development, and sale of KOIZUMI branded products across four categories — beauty appliances (anchored by the long-selling MONSTER hair dryer line featuring proprietary BLDC double-fan technology with 100,000 RPM and patented Flex Nozzle), cooking appliances (IH cookers, rice cookers, toasters), seasonal appliances (heaters, kotatsu, humidifiers), and audio equipment; and (2) distribution and sales agency for approximately 83 domestic and overseas brands including Anker, TCL, Sodastream, Miele, KitchenAid, JBL/Harman, ECOVACS, TOTO, Paloma, Omron Healthcare, Tiger Corporation, Nestle Japan, and others, spanning roughly 36,000 SKUs.

The company runs a fabless manufacturing model, contracting production to overseas partner factories, and operates a nationwide B2B go-to-market motion with approximately 150 dedicated sales representatives calling on major electronics retail chains, home centers, GMS, drugstores, and discount stores. It supplements this with direct-to-consumer channels (own online shop and Rakuten marketplace) and an annual "LIFE CREATION" comprehensive exhibition serving as the primary demand generation event for retailers. KOIZUMI generates revenue primarily through hardware sales of branded products and transaction-based distribution fees from third-party brands.

KOIZUMI operates 19 domestic business locations plus 2 overseas subsidiaries (Hong Kong and Shenzhen, established 2016-2017), employs approximately 281 people (as of March 2026), and reports revenue of 677 billion JPY for fiscal year ending March 2025. Per capita sales of approximately 2.3 billion JPY reflect the high-throughput distribution-heavy business model. The company is part of the broader Koizumi Group, whose heritage traces back to 1716, and maintains banking relationships with Mizuho Bank, Mitsubishi UFJ Bank, and Sumitomo Mitsui Banking Corporation.
