What Fujiclean does

Fujiclean (フジクリーン株式会社 / FujiClean Co., Ltd.) is a privately held Japanese manufacturer of on-site wastewater treatment systems, founded in 1961 and headquartered in Nagoya, Aichi Prefecture. The company designs, produces, and sells jokaso (浄化槽, septic tanks) across small (5-10 person), medium (12-50 person), and large (51+ person) capacities, with proprietary process technologies including contact aeration, carrier-fluidization biological filtration, and an iron electrolysis chemical-free phosphorus removal unit (CRX/CRX II). Its pillar-embedded FRP tank architecture (I型) and self-manufactured EcoMac-series diaphragm blowers are internally cited as differentiators, with documented performance metrics of BOD ≤10 mg/L, T-N ≤10 mg/L (77.8% removal), T-P ≤1 mg/L (80% removal), and blower-driven electricity costs as low as ~13 yen/day. The company also produces industrial wastewater treatment units for kitchen, medical/dialysis (FJPⅡ, FJR), and livestock (FGR) applications, plus accessory products such as pumps, manholes, and grease separators, and ISO 14001 / ISO 27001 certifications are held.

The business model combines hardware sales (the dominant revenue stream) with a recurring maintenance-and-support layer delivered through a nationwide office network. Fujiclean sells directly to end customers including individual homeowners, residential developers, public-sector facilities (schools, hospitals, government buildings), and industrial operators in food processing, healthcare, and agriculture. Product pricing is "open pricing" (オープン価格) and quote-based rather than list-based. Distribution is direct via regional sales offices in Japan and through international offices in Australia, the United States, and Europe; international channels are being actively expanded through trade-show participation (IFAT Munich 2026).

On the customer side, named reference users are limited — disclosed case studies include a Hokkaido hospital using FJPⅡ for dialysis wastewater discharge and Hanakemon Farm (株式会社花兄園ファーム) using FGR for egg-washing wastewater — but the customer base is otherwise broadly distributed across residential, public, and industrial verticals with no single dominant account disclosed. The CEO is represented by 後藤雅司 (President and Representative Director), and the company underwent a name change and headquarters relocation effective October 1, 2025, alongside a Tokyo branch relocation in October 2024 and an April 1, 2026 product launch of the CB型 ultra-shallow small septic tank.
