PSYS

What PSYS does

PSYS (株式会社パーソナルシステム / Personal System Co., Ltd., "Personal System") is a privately-held Japanese software development company founded in June 1991 in Hiroshima and incorporated as a Kabushiki Kaisha in September 2001 with ¥13.2M of registered capital. The firm employs approximately 20 staff as of April 2025 and operates from two offices: a company-owned headquarters at Kamiya-cho, Naka-ku, Hiroshima, and a regional office at Shinagawa Grand Central Tower, Minato-ku, Tokyo (relocated from Shiodome in September 2021). The business spans four revenue streams — custom software development, packaged software licenses, recurring ASP/cloud subscriptions, and hardware resale — with primary customers in Japanese labor unions, small-to-medium enterprises, and specialized vertical operators including ports, airports, marinas, timber markets, and septic-tank maintenance firms.

The product portfolio is anchored by three proprietary brands. ULTRA-UNION 7 is a purpose-built labor union accounting and member-management system sold as a one-time perpetual license (¥250,000–¥500,000 base price with mandatory year-one maintenance), addressing a niche underserved by mainstream enterprise accounting software because of union-specific reporting structures and Rikoku format requirements. EASY-BANK 7 is a ¥58,000 bank transfer data management tool for SMEs that exports to the 全銀協 unified format with pre-loaded nationwide bank/branch master data. WIND.JP.NET is a cloud-based real-time wind monitoring ASP service that combines proprietary ultrasonic anemometer hardware (PGWS-100 Windsonic and polar-grade heated models) with a web platform capable of 0.8-second transmission intervals, used for crane safety, port operations, marina management, and disaster prevention. Additional offerings include the PSYS Web Hosting Pack (¥5,720–¥22,000/month across three tiers), the Hiroshima Wood Place timber auction ASP, and bespoke solutions for marina, septic-tank, building-materials, and timber verticals. The technology stack spans Windows, Linux, and Mac with .NET, VB, C, C++, Java, SQL Server, and Oracle.

Commercially, PSYS runs an enterprise field-sales model from its two offices, supported by downloadable 60-day trial software for ULTRA-UNION and EASY-BANK and direct phone/contact-form sales for custom development and WIND.JP.NET. Long-standing referral and reseller agreements with major Japanese technology vendors — including Fujitsu FIP (2005), Fujitsu Marketing (1999), Daiko Electronics (2004), MHI Information Systems (1997), KDDI (1998), and NTT Communications (2014) — supplement direct sales, and a 2022 sponsorship with the Hiroshima Dragonflies B.League team supports regional brand visibility. Revenue is not publicly disclosed, the company has no external funding, and ownership is concentrated with founder Representative Director Koshi Furumoto (古本賢士).

Scale indicators5 records

Recent moves9 records

Expansion highlights5 records

Emerging players

• freee K.K. freee offers cloud-native accounting, HR, and payroll SaaS for Japanese SMBs — emerging alternative to PSYS-style custom/packaged solutions. Comparable target customer (Japanese SMB) and overlapping accounting product (freee 会計) versus EASY-BANK and custom accounting work.
• Money Forward: Money Forward provides cloud accounting, payroll, and expense-management SaaS for Japanese SMBs and personal finance. Targets the same accounting/finance workflow PSYS addresses via EASY-BANK and ULTRA-UNION, but with a cloud-only delivery model.

Broad incumbents

• Weathernews Inc. Weathernews is Japan's largest private weather-information company, offering real-time wind/weather monitoring for ports, aviation, and industry. Comparable to WIND.JP.NET's industrial wind-monitoring use cases (ports, airports, marine safety), but at much broader scope and scale.
• TKC Corporation: TKC provides professional accounting/tax software and outsourced services for accounting firms and SMBs in Japan. Comparable as a long-tenured Japanese on-premise-and-cloud accounting software publisher serving similar verticals to PSYS's ULTRA-UNION/EASY-BANK customer base.

Direct peers

• Cybozu: Cybozu sells kintone and Garoon groupware/CRM-style cloud platforms to Japanese SMBs and divisions. Comparable as a packaged-software-plus-customization vendor competing for the same Japanese mid-market software budget that PSYS targets.
• Yayoi (Yayoi Co., Ltd.): Yayoi is the leading Japanese SMB accounting/payroll packaged-software vendor (弥生会計), with strong brand and partner channel. Direct comparable to PSYS's packaged-software strategy and SMB accounting/finance product focus, though at much larger scale.
• PCA Corporation: PCA is a Japanese packaged software vendor focused on accounting, payroll, and sales management for SMBs — directly comparable to PSYS's EASY-BANK and custom ERP/sales offerings. Both companies serve Japanese SMBs with on-premise + cloud packaged software plus add-on modules.
• OBC (Ōsaka Business Cyō): OBC provides integrated ERP (勘定奉行, 給与奉行) and business application suites for Japanese SMBs and mid-market — the closest large analog to PSYS's custom-and-packaged ERP development model. Overlap in accounting and member/payroll-style packaged software is significant.

Others

• NTT Data (Japan): NTT Data is Japan's largest SI and a long-standing PSYS partner (via NTT Communications). Functions more as a customer/referral source than direct competitor, but its packaged enterprise software competes for the same Japanese enterprise custom-development budgets PSYS serves.

Regional players

• Satoru Electric Co., Ltd. (サトデン): Satoru Electric is a regional Hiroshima-area IT services and packaged software firm. Comparable in size and region to PSYS, with similar dual-product mix of custom development plus packaged solutions for Japanese SMBs and local government customers.
