What I'll Group does

I'll Group is a privately held Japanese holding company founded in 1967 and headquartered in Saitama City, operating eight wholly-owned subsidiaries that deliver essential urban and community services across the Kanto region. Its core service lines fall into three integrated segments: (1) Facility & Environment Management — I'll Corporation handles PPP (public-private partnership) projects, designated administration of public facilities, and comprehensive building management; Clean System manages industrial and household waste collection, disposal, and recycling through Eco Center Yamabuki; I'll Clean Tech operates the nation's first pallet-based automatic organic-resource recycling system (2,700 pallets, 10,000+ tons/year capacity); and Aiba Sangyo provides fire equipment inspection, installation, and building management. (2) Real Estate & Asset Management — I.S.C. delivers apartment and condominium management across 3,400+ properties. (3) Elderly Care & Welfare — Asunaro Home and Asunaro Kai operate group homes, day services, dementia care, visiting nursing, special nursing homes, short-stay, and a chef-driven catering sub-brand, Asunaro no Itamae-san.

Revenue is generated through a mix of long-term managed-services contracts (facility management, eldercare under Japan's kaigo hoken reimbursement system), per-collection/tonnage transaction fees (waste and recycling), professional services fees (fire inspection, consulting), and unit-priced sales of branded compost products (めばえ, アドニス, みのり, 穂のか, あまめ) ranging from 418 yen/bag to 2,000 yen/flex container. The group serves primarily Saitama Prefecture and the broader Kanto region, with enterprise/government customers including Urawa Red Diamonds, Moomin Valley Park, Tokyo Monorail, Fujita Kanko hotels, Rengo factories, Sekisui House Shamerion PM, and Saitama Prefectural Housing Corporation, alongside a long tail of property owners, households, and businesses. Distribution is direct and field-based, with subsidiaries running their own sales teams; growth is driven by PPP tender wins (2 prefectures, 21 cities/towns, 114 facilities), long-tenured client relationships (30+ years with Urawa Reds), and selective geographic branching into Chiba (2019) and Kanagawa (2023). The group holds ISO 14001 (2000) and ISO 27001 (2006) certifications, multiple industrial and general waste collection permits, and trademarked proprietary systems including the Paper Kurett confidential-dissolution service and the pallet-type recycling platform.
