Maruichi

What Maruichi does

Maruichi Co., Ltd. (マルイチ株式会社) is a privately held Japanese construction temporary materials and equipment rental company headquartered in Himeji, Hyogo Prefecture, operating as a member of the Yoshikawa Group. The company's core business is the rental and managed assembly of construction scaffolding, frame scaffolding, steel pipes, supports, sheets, gates, and related temporary infrastructure to building-construction companies, executing approximately 17,000 residential scaffolding installations per year (described as top-class in the Kansai region) entirely with its own workforce rather than subcontractors. Maruichi also rents connected unit houses, office equipment, and welfare/care equipment under the Hanamaruichi (花まるいち) brand, and operates industrial solar power generation totaling 30,429kW across 19+ facilities under a design-build-maintain managed service model.

Maruichi runs a vertically integrated operations stack: design is handled in-house using 3D CAD/BIM, equipment is held in self-owned yards totaling 136,200㎡ across 21 equipment centers with approximately 150,000 tons of self-owned inventory, and delivery/retrieval is performed by a wholly-owned logistics subsidiary (Maruichi Transport Co., Ltd.) operating a 236-vehicle fleet. The firm runs its own Vocational Training School (certified by the Hyogo Prefecture Governor since 2012) producing scaffolding technicians in 315 hours of curriculum, which feeds the in-house assembly workforce and underwrites the next-generation, regulation-compliant scaffolding system the firm has commercialized. Regional footprint covers Hyogo, Osaka/Kobe, Okayama, Tottori, and Hiroshima with dedicated enterprise field sales at each branch.

The revenue model is overwhelmingly subscription/recurring rental, with quotation-based project pricing for construction rentals and government-insurance reimbursement pricing for welfare equipment (with 10-30% user co-pay depending on care level). Customers include enterprise construction companies, residential builders and homeowners, construction-site operators, landowners seeking renewable-energy monetization, and elderly/care-recipients. Founded in 1977 (spun off from Yoshikawa Co., Ltd., with predecessor activity dating to 1975) and led since May 2023 by President Kobayashi Joji, Maruichi employs 335 people across the group and is expanding westward into Chugoku/San'in markets through new sales offices (Hiroshima, Kurayoshi) and regional subsidiaries (Tottori Maruichi).

Direct peers

• Kanamoto Co., Ltd. One of Japan's largest construction equipment rental companies, listed on the Tokyo Stock Exchange. Like Maruichi, Kanamoto rents scaffolding, temporary equipment, and construction machinery to contractors nationwide — directly comparable on core product, customer base, and rental business model.
• Actio Corporation: Construction equipment rental company operating across Japan with focus on temporary construction materials and machinery. Directly comparable to Maruichi in target customer (construction firms), product (scaffolding/equipment rental), and distribution model (regional branches). Notable for being a Nikken Lease group entity.
• Nishio Rent All Co., Ltd. Major Japan-based construction equipment rental company with broad portfolio covering scaffolding, temporary materials, and event/rental solutions. Closely comparable to Maruichi on rental business model, scaffolding focus, and customer base of construction companies.
• Nikken Lease Industries Co., Ltd. Japan-based major scaffolding and construction equipment rental provider with national coverage. Directly overlaps with Maruichi's core temporary scaffolding rental business for both commercial construction sites and residential projects.

Emerging players

• Modec, Inc. Japan-based modular building and temporary facility rental company. Comparable to Maruichi's connected unit house rental business serving construction sites, but more specialized in modular/temporary space and lacking Maruichi's scaffolding scale.

Broad incumbents

• United Rentals, Inc. World's largest equipment rental company, with extensive general construction and industrial equipment offerings. A useful broader-market comparable for Maruichi's fleet utilization and rental economics, though at vastly greater scale and scope than Maruichi's scaffolding-focused Kansai business.
• Herc Holdings Inc. North American equipment rental company offering a broad range of construction and industrial equipment including aerial, earthmoving, and specialty items. Relevant industry comparable for rental business model and exposure to construction end markets, though with a different geographic footprint than Maruichi.
• Ashtead Group plc (Sunbelt Rentals): UK-listed parent of Sunbelt Rentals, the second-largest equipment rental company in North America. Comparable as a broad incumbent in the construction equipment rental category, including scaffolding and aerial work platforms — though Maruichi operates at a substantially smaller and more regionally concentrated scale.
