EiShin Co., Ltd.

What EiShin Co., Ltd. does

EiShin Co., Ltd. (株式会社EiShin) is a privately held Japanese company founded in 2002 and headquartered in Shinagawa, Tokyo. The firm manufactures and sells eco-SPRAY (エコスプレー), a 100% natural-ingredient spray applied to vehicle air filters that the company claims improves fuel efficiency and reduces exhaust emissions; a companion trademarked product, eco-RADI (エコーラジー), complements the line. The product is sold through a one-time-purchase revenue model via the company's direct e-commerce channel in Japan and via a network of exclusive regional distributors across the Philippines, Bangladesh, China, Ghana, Nepal, Cambodia, UAE, and other markets, with the broader strategy tied to a stated 10-year objective of capturing 10% market share per country.

The company targets both individual vehicle owners seeking fuel-cost relief and commercial fleet operators (taxi, logistics, shipping) seeking fleet-wide fuel efficiency, with secondary positioning around environmental regulation compliance in emerging markets with significant used-vehicle air pollution. It pursues a multi-channel go-to-market combining DTC e-commerce, distributor-led international sales, event-driven demand generation via environmental and automotive trade shows (SEMA SHOW, EcoProducts, Japan Truck Show, Kawasaki International Environmental Technology Exhibition), and earned media in Japanese business press plus international outlets including Emirates Airlines' LAYALI DUBAI magazine and Cambodian news programs. Strategic moats rest on regulatory credentials (UNIDO Environmental Technology Database registration, UNIDO Global Call 2022 Top 30 of 452, Cambodia government endorsement, Cabinet Office STI for SDGs selection), registered trademarks, motorsports credibility via Audi Team Dream Drive sponsorship in the Super Taikyu series, and an eight-country exclusive distributor footprint.

The firm operates with 1-10 employees, is founder-led by representative Yasunaga, has not raised disclosed outside capital, and discloses no revenue figures. Recent activity through 2024-2025 (China distribution confirmation, Philippines Environment Week participation, Japan Truck Show 2024, ongoing Kawasaki exhibition presence, Kanagawa Keizai Shimbun coverage) indicates continued but unscaled operations anchored in a single physical SKU with no apparent AI, software, or recurring-revenue components.
