What AK corporation does

AK Corporation (AKC / AKコーポレーション株式会社) is a privately-held Japanese construction firm founded on February 21, 2012, headquartered in Osaka with a regional branch in Tokyo (Minato-ku). The company plans, designs, and constructs hotels, retail stores, and commercial facilities, operating across three core service lines: 建築総合施工 (general construction), 建築設計監理 (architectural design supervision), and 土木設計施工工事 (civil engineering design and construction). Supporting functions include construction drawing creation using JWCAD software and quantity surveying using TDS建築積算ソフト. AKC positions itself as a "technology group" (技術集団) focused on craftsmanship and customer satisfaction (CS), targeting design and architecture firms that require a reliable execution partner to translate their designs into built form.

The company generates revenue through project-based construction contracts (one-time engagements) with commercial facility owners and design offices, with pricing negotiated case-by-case and not publicly disclosed. Its go-to-market is direct B2B relationship selling — phone and web-form inquiries generate leads, and contracting happens directly with property owners and design firms. Recent project completions span hospitality (HOTEL Asakusa Yokozuna, HOTEL MINATO, THE PASADENA 11 HOTEL, MOTHER2/3), retail (Valor Yokohama Shimonagaya, Asway Hiroo), residential-commercial (N-stage Nishitanabe), and civil engineering (Yokohama fence installation) — indicating a diversified but regional project book across Japan.

Operationally, AKC holds a national construction license (国土交通大臣 許可 特-7 第29519号), carries registered capital of ¥80M, and is led by Representative Director Hirashima Motoyuki alongside two board directors. The firm is actively hiring across construction management, drafting, and quantity surveying, and supports the Tokyo 2025 Deaflympics as a CSR initiative. Its technology stack is entirely built on standard Japanese industry tools (JWCAD, TDS) with no proprietary or AI-enabled systems disclosed. Ownership is founder/management-led with no institutional investors or parent company identified in available material.
