ALSOK Aichi

What ALSOK Aichi does

ALSOK Aichi (ALSOK愛知株式会社) is a regional Japanese security services provider founded in 1999 and headquartered in Nagoya, Aichi Prefecture. The company operates as a wholly-owned subsidiary of the ALSOK Group, one of Japan's largest security service conglomerates, and delivers physical security guard services (警備サービス) to retail stores, commercial facilities, and high-rise buildings across Aichi Prefecture. Its service portfolio centers on uniformed guard deployment, facility access control, and safety monitoring for local commercial and residential high-rise customers, with no disclosed technology or product extensions beyond traditional guarding.

The company generates revenue through recurring contracted security service arrangements, quoted on a contact basis rather than via public pricing. Its go-to-market is sales-led and direct, relying on telephone (052-252-5110) and web inquiry channels to acquire customers, with no named enterprise anchor accounts or public customer logos disclosed. Marketing is minimal and primarily conducted through the company website (alsok-aichi.jp), which serves as both informational and lead-capture surface, supplemented by occasional CSR and community sponsorship activity.

ALSOK Aichi is privately held with no public ticker, no external funding rounds disclosed, and no subsidiary entities of its own. The company employs 251-500 people and is currently navigating an announced corporate restructuring — a merger and name change, alongside an ongoing head office renovation beginning May 2026 — that signals upcoming changes to its legal and operational structure within the ALSOK Group network. No AI capabilities, patents, certifications, or technology partnerships are disclosed.

Expansion highlights3 records

Regional players

• Tokyu Security Co., Ltd. Security services subsidiary of the Tokyu Group, focused on the greater Tokyo area but offering guard services comparable to ALSOK Aichi's. A useful regional comparable for high-rise and commercial contracts.

Direct peers

• Universal Security Co., Ltd. Mid-sized Japanese manned-security and facility services provider serving commercial and high-rise customers. Comparable to ALSOK Aichi as a regional guard-services competitor targeting similar customer use cases.
• Secom Co., Ltd. Japan's largest security services company, offering manned guarding, electronic security, and monitoring services nationwide. Directly competes with ALSOK Aichi in Japanese physical security, particularly for retail, commercial, and high-rise contracts in Aichi.
• Central Security Patrols (CSP): Japan's #3 manned security services firm (セントラル警備保障). Competes with ALSOK and Secom for retail, facility, and high-rise guard contracts across Japan, including in Aichi.
• ALSOK Tokyo Co., Ltd. Sister ALSOK Group regional subsidiary serving Tokyo and Kanto. Operates with the same ALSOK playbook, brand, and service menu as ALSOK Aichi but in a different region — useful for group-level benchmarking.

Broad incumbents

• Sohgo Security Services (ALSOK Group): The parent ALSOK Group / Sohgo Security Services, Japan's #2 security company with nationwide coverage. Operates a network of regional subsidiaries — of which ALSOK Aichi is one — and offers the same core guard services at scale.
