HIYOSHI INDIA

What HIYOSHI INDIA does

Hiyoshi India Ecological Services Private Limited is a Chennai-based, 100%-owned subsidiary of Hiyoshi Corporation, Japan (established 2011), operating as a B2B environmental services firm. It sells an integrated 'one-stop' water and wastewater management offering to industrial, hospitality, residential, commercial, and institutional clients across India. The portfolio comprises five core service lines: NABL-accredited (ISO/IEC 17025:2017) environmental laboratory testing, plant operation and maintenance (WTP/STP/ETP/RO/NANO/UF/DM), turnkey project execution and revamping, environmental consultancy, and student training/internship programs.

The technical foundation rests on a NABL-accredited chemical-testing laboratory established in 2014 and progressively expanded — including an ICP-OES heavy-metal facility in 2020 and CALUX Bioassay capability for dioxin screening (officially approved under EU Directive 2002, Japan MOE 2005, EPA Method 4435, and JIS K0463 2009). Onsite testing uses Japanese pack-test methods and portable water-quality meters, with specialized capabilities in microorganism study and JAR testing for chemical-dose optimization.

The business is service-revenue driven and quote-based. Revenue streams are a mix of recurring lab testing (per sample/analysis), recurring O&M contracts (monthly, including 24/7 operator supply), and episodic turnkey and consultancy projects. Go-to-market is direct enterprise sales plus relationship leverage through Japanese diplomatic and trade bodies (JCCIC, ABK-AOTS Dosokai, Consulate General of Japan, JICA, India-Japan Environment Week), with a customer roster spanning Japanese corporates in India (SMCC, THK, Shin-Etsu), Indian heavy industry (BHEL), premier hospitality (Taj Coromandel, The Leela Palace), academic institutions (SRM, Sathyabama), and residential developers. The firm runs on 17 employees in a single Chennai office and reinvests in partnerships and accreditation scope rather than raising external capital.
