What No 1 Co does
No.1 Co., Ltd. (株式会社No.1, TSE Standard: 3562) is a Japanese IT/security equipment distributor and business support services provider founded in 1989 (predecessor), headquartered in Chiyoda-ku, Tokyo, and operating nationwide with branches in Yokohama, Chiba, Saitama, Osaka, Nagoya, and Fukuoka, plus multiple service centers. The company serves Japan's small-to-medium enterprise base (~4 million corporations) as its primary customer, supplemented by government/public-sector sales via bidding, and operates a hybrid distribution model combining direct sales, FC franchise stores (No.1 Shonan, No.1 Ryomo, No.1 Maebashi), agency partners, and TeamViewer-based remote PC support.
The business is organized across four revenue streams: (i) IT and information security equipment sales, including proprietary UTM machines and security servers manufactured in-house by subsidiary Alexson; (ii) recurring "No.1 Business Support" services featuring dedicated business consultants covering management support, PC operations, recruitment assistance, and cloud-based business administration; (iii) agency/franchise sales; and (iv) maintenance services on installed equipment. More recently, the group has expanded into BCP-oriented portable battery systems through subsidiary I Station (EnerCraft brand, PGJ5200PRO / PGJ2600PROMAX / PGJ2600B) and a November 2025 co-development partnership with Naturenix, with large-format batteries scheduled for autumn 2026.
Financially, No.1 reported FY2025/2026 (year ended February 2026) revenue of JPY 17.5B, operating profit of JPY 1.33B (~7.6% margin), net income of JPY 710M, ROE of 16.1%, and an equity ratio of 31.2%, with 957 employees. In March 2026, the company absorbed subsidiary No.1 Digital Solution via merger, consolidating web support operations under the parent entity.
