What ALSOK does

ALSOK Aomori (Aomori Sohgo Security Services Co., Ltd. / 青森綜合警備保障株式会社) is a regional Japanese security services subsidiary of the publicly traded ALSOK Group (Sohgo Security Services, TSE-listed, ISIN JP3160000000), headquartered in Aomori City and operating 10 offices across Aomori Prefecture and Odate in Akita Prefecture. Founded in 1970 as the first full-scale security company in Aomori Prefecture, the company employs 716 staff as of May 2026 and is preparing to rename itself ALSOK Aomori Co., Ltd. effective July 1, 2026.

The company operates a 24/7 Guard Center that monitors customer facilities via sensors and alarm systems, dispatching mobile response teams upon activation, and provides stationed security personnel at client sites including retail stores, offices, banks, airports, and nuclear facilities (Higashidori Branch). Technology stack includes the proprietary ALSOK Guard System (with ALSOK-GV and ALSOK-MP variants), GTACS IC-card access control system, OLM System II cash deposit/withdrawal machines for retail, ALSOK Monitoring Camera System and Image Cloud Service, and the REBORG-Z security/guidance robot. Consumer offerings are anchored by HOME ALSOK Connect (smartphone-controlled home security from ¥990/month), with elderly monitoring (Mimamori Support, Mimamori Tag), women's safety services (Ladies Support, Mamoruck), vacancy management (Rusutaku), and the recently launched GS/HS Plus paid dispatch service.

Revenue is generated primarily through recurring monthly subscriptions across mechanical security monitoring, stationed guarding, cash-in-transit, and home security, supplemented by one-time equipment installation fees and usage-based dispatch fees. Customer segments include corporate/enterprise clients, individual/residential consumers, government and public infrastructure (airports, nuclear facilities, Aomori Prefectural Government), and community/safety education programs. The go-to-market combines direct field sales with prior guard experience at the branch level, dedicated inside-sales phone lines (0120-711-806), and website self-service inquiry channels.

Others

• Tokio Marine & Nichido (security-adjacent insurance): Large Japanese insurer offering bundled security/insurance products similar to ALSOK's bundled ALSOK Insurance offering. Not a direct security competitor, but a potential bundling partner or alternative for risk-transfer solutions in the same customer base.
• Nihon Unisys (security systems integration): Japanese systems integrator providing enterprise security systems and access control solutions. Adjacent to ALSOK Aomori's GTACS and surveillance camera lines; could be a technology partner or competitor for larger corporate access-control RFPs.

Direct peers

• Secom Co., Ltd. Japan's largest security services company and direct competitor to the ALSOK Group. Offers online security, manned guarding, home security (SECOM Home Security), cash-in-transit, and disaster prevention services across Japan. Highly comparable business model and product portfolio to ALSOK Aomori, with broader national coverage.
• Central Security Patrols Co., Ltd. (CSP): National Japanese security firm (TSE: 9740) offering online security, manned guarding, and cash-in-transit services. Comparable online/manned guarding product mix; serves both enterprise and residential customers across Japan.
• Nihon Keibi Hosho Co., Ltd. (ALSOK Tokyo): Another ALSOK Group regional operating subsidiary, headquartered in Tokyo. Uses identical brand, products, and service model as ALSOK Aomori, differing mainly in geography. Most direct internal comparable for the Aomori subsidiary's economics and product mix.

Emerging players

• Aichi Sharyo / local Aomori security firms (8-company coalition): Eight local Aomori security companies participate in the police video-evidence sharing coalition alongside ALSOK Aomori. These regional rivals compete directly for SME and residential contracts in the same prefecture, with similar local relationships but smaller scale and brand presence.

Broad incumbents

• Sohgo Security Services Co., Ltd. (ALSOK Group parent): Parent company of ALSOK Aomori and Japan's #2 security firm by revenue. Provides the shared technology platform, brand, and group-wide service portfolio. Comparable at the business model and product level; sets the strategic direction the regional subsidiary executes against.

Regional players

• Secom Trust Systems / Secom Home Security regional subsidiaries: Secom's regional operating companies provide the same product portfolio as ALSOK Aomori (online security, home security, cash-in-transit) across Japanese regions. Direct competitor in the Tohoku/Aomori market with equivalent service depth but distinct regional brand.
