What ASON does

ASON (株式会社アスオン) is a Saitama Prefecture-based construction subcontractor founded in May 2021 and headquartered in Ageo City. The company delivers mobile base station construction (negotiation, survey, design, construction, and management), electrical equipment installation for residential and commercial properties (including high-voltage receiving and transforming equipment), and telecommunications infrastructure work such as LAN cabling, office information systems, inter-site VPN connections, and wireless LAN access point installation. It also offers maintenance and emergency response services for completed installations and operates a small consumer-facing sub-brand called 'Asuwan Service' for electrical troubleshooting restricted to the Ageo area on weekdays.

ASON's revenue model is project-based construction fees across these service lines, with work delivered through its own staff supplemented by recruited partner companies and individual contractors (一人親方). The company holds Saitama Prefectural Governor-issued permits for both electrical engineering business (General-3 No. 74871, Dec 2021) and telecommunications engineering business (General-4 No. 74871, Jun 2022), which are mandatory to bid on telecom and electrical construction work in Japan. It maintains banking relationships with Mizuho Bank, Saitama Resona Bank, Musashino Bank, and Kawaguchi Shinkin Bank.

The business operates entirely within Japan with no disclosed geographic expansion beyond Saitama Prefecture. Primary go-to-market is enterprise field sales to mobile carriers and telecommunications companies, with secondary work for residential and commercial property owners and a narrow direct-to-consumer channel in Ageo City. The company is privately held (Kabushiki Kaisha), led by Representative Director Ohsaki Koichi (大崎晃一), and has not disclosed revenue, headcount, funding, or valuation. The website functions as the principal marketing channel, with direct email as the primary customer contact method.
