DAISAN

What DAISAN does

DAISAN Co., Ltd. (株式会社ダイサン, TSE: 4750) is a Japanese construction services company founded in 1975 and headquartered in Osaka. It designs, manufactures, sells, rents, and assembles scaffolding — primarily its proprietary Bike scaffolding (ビケ足場) system, which it pioneered as an integrated design-build-rental offering for the Japanese market. The company's core technology is a modular tubular steel scaffolding platform supplemented by next-generation Le-volt (レボルト) systems, with associated digital tools including 3D planning, the KATETOS safety reporting app co-developed with the Temporary Scaffolding Industry Association, and the Gyogan-kun (魚眼くん) 180-degree fisheye camera for remote site monitoring. DAISAN was the first company in the scaffolding industry to obtain ISO 9001 certification and operates under a "providing safety, not just scaffolding" quality philosophy.

DAISAN generates revenue through two primary streams: a Construction Service Business (施工サービス事業) that handles end-to-end site investigation, design, on-site assembly, verification, and dismantling for construction companies and infrastructure projects; and a Product Sales Business (製商品販売事業) that sells and rents scaffolding equipment and components, with downloadable CAD data and certification documents. Pricing is quote-based and project-specific, typically structured as multi-year service contracts. Distribution runs through a national service-center network across Japan covering the Kansai, Kanto, Kyushu, Chugoku, and Tohoku regions, augmented by the Bike-kai (ビケ会) affiliate program.

Beyond domestic scaffolding, DAISAN has expanded internationally through wholly-owned subsidiaries in Singapore (Mirador Co. Pte. Ltd., acquired 2020), Vietnam (DRC, acquired 2018), and System In International (acquired 2022) for IT services. It operates a Kanto regional headquarters in Tokyo and, in 2026, established a joint-venture Sakai Academy in Indonesia to train foreign drivers for Japan's logistics sector — a notable diversification beyond its core construction services footprint.
