LSi

What LSi does

LSi (株式会社エル・エス・アイ, headquartered in Nagasaki, Japan) is a privately held IT services company founded on October 1, 1986, that operates three interrelated business lines: custom system development outsourcing, technical personnel dispatch, and DX training. The company develops business systems (ERP, production management, factory optimization, materials logistics, cost and quality management), monitoring systems (transportation, disaster prevention), Android/iOS native and hybrid mobile applications, embedded systems (label printers, time tracking devices, automotive), and infrastructure (network and server construction, operations, and maintenance). Its technical stack spans C, C++, C#, VB, Java, PHP, Objective-C, and HTML/CSS/JavaScript across Windows, UNIX, Linux, macOS, Android, and iOS, with database expertise in Oracle, SQL Server, MySQL, PostgreSQL, and SQLite.

The company serves manufacturing and enterprise clients in the Kyushu region of Japan, primarily through direct sales and referrals, with a Nagasaki headquarters and a Fukuoka sales office supporting regional coverage. It holds both a specialized worker dispatching license (obtained 1997) and a general worker dispatching license (派42-300147, obtained 2017), though the dispatch business reported 0 active placements as of June 2025. The newer DX training service (エル・エス・アイDX推進研修) offers subscription-style unlimited course access covering generative AI, digital marketing, and operational digital transformation. LSi is funded entirely through organic retained earnings — capital has been incrementally increased from ¥10M (1986) to ¥50M (2005) — with no disclosed external investors, parent company, or subsidiaries.

The go-to-market is sales-led and relationship-driven: direct outreach, referrals, membership in the Nagasaki Prefecture Information Industry Association, and an active recruitment presence on Mynavi for new graduate hiring. The company is led by Representative Director Nezumi Shingo (根〆 眞悟) and operates with 11–50 employees, a scale consistent with a specialized regional system integrator rather than a scaled platform business.

Broad incumbents

• Otsuka Corporation: Established Japanese IT services and OA equipment sales company with system integration, support, and staffing capabilities. Aligns with LSi's combined IT equipment/system sales plus service orientation but at significantly larger scale.
• NTT Data Group: Japan's largest IT services provider with national coverage in system integration, consulting, and outsourcing. Provides the upper bound of competitive intensity that regional players like LSi face when pursuing enterprise contracts.
• NS Solutions Corporation: Major Japanese system integrator with strong manufacturing-industry focus, providing custom systems, infrastructure, and consulting. Competes with LSi in the manufacturing vertical but serves national accounts and operates at much greater scale.
• TIS Inc. One of Japan's major independent IT services groups offering system integration, outsourcing, and DX consulting. Operates broadly across the same services as LSi but at far larger scale and national footprint, including Kyushu delivery centers.

Direct peers

• Fuji Soft Incorporated: Mid-sized Japanese system integrator and embedded software developer offering custom development, infrastructure, and maintenance services. Comparable to LSi's broad custom development and embedded systems offerings.
• Trust Technology (now part of CRESCO Group): Japanese technical staffing and engineering services firm specializing in software, electronics, and embedded development outsourcing — overlapping with LSi's embedded systems and IT engineer dispatch capabilities.
• Meitec Corporation: Japan's largest independent engineering staffing and outsourcing firm, dispatching engineers to manufacturers and IT clients. Closely comparable to LSi's licensed worker dispatch and system development outsourcing model, though at significantly larger scale.
• Akros Inc. Japanese IT engineer staffing and system development services company. Directly comparable business model of dispatching IT engineers and providing outsourced development, with similar customer profile of manufacturers and enterprises.

Regional players

• Kyocera Communication System Co., Ltd. Mid-sized Japanese system developer and SI firm with presence in Kyushu and western Japan, providing embedded, mobile, and enterprise systems. A regionally anchored comparator that targets similar Kyushu-based enterprise customers as LSi.

Emerging players

• BayCurrent Inc. Japanese management and digital transformation consulting firm that combines strategy, technology, and DX implementation. Represents a more upscale, advisory-led competitor to LSi's DX研修 and DX system development offerings.
