Business Support

What Business Support does

株式会社ビジネスサポート (Business Support Co., Ltd.) is a privately held Japanese IT systems integrator founded in April 1996, headquartered in Saitama City, and operating regional satellite offices in Gunma (since 2008) and Tochigi (established December 2025). The company resells, customizes, implements, and supports business management software — primarily for small and medium enterprises in Saitama Prefecture and the broader Kanto region. Its core product surface spans sales management, payroll and attendance, financial accounting, and construction project management systems, with additional lines in security/office equipment and website production services. Business Support is a multi-vendor authorized dealer for CASIO 楽一 (Rakuichi), 応研 大臣シリーズ (Oken Minister series), PCA, and ラクス (Rakus Rakuraku series), and operates its own proprietary original system called みまさか販売管理 (Mimasaka Sales Management) developed in-house using VB, COBOL, and a proprietary Mimasaka language. In December 2024 the company launched EZ販売管理, a subscription-based (SaaS) sales management product built on CASIO's platform with cloud-hybrid architecture and integrations to major Japanese logistics carriers (Yamato, Sagawa, Seino, Japan Post).

The company's business model combines multiple revenue streams: one-time software licensing and customization fees, hardware sales (security/UTM, multifunction printers, business phones, NAS, AI cameras), recurring maintenance and subscription contracts (including the EZ販売管理 monthly subscription), and project-based fees for website production (starting from ¥450,000 for a five-page site). Leasing arrangements via partners such as 昭和リース and 三井住友トラスト・パナソニックファイナンス reduce upfront capital requirements for SME buyers. Go-to-market is anchored on direct field sales with on-site needs assessment in Saitama and surrounding prefectures, supplemented by inbound phone/web inquiries, SEO-optimized product landing pages, and event participation in regional exhibitions such as 彩の国ビジネスアリーナ and the Saitama DX Expo. The company targets SME verticals with paper-heavy or analog workflows — manufacturing/wholesale, construction/engineering (especially under April 2024 overtime regulation pressure), and transportation/warehousing — and serves over 1,000 cumulative customers across 27 years of operation.

Business Support holds memberships in the CASIO, PCA, and 大臣 series consortia for IT introduction subsidy programs, holds IPA SECURITY ACTION two-star status, and is certified as a Health Management Excellence Corporation (2025 and 2026, Medium/Small Enterprise category). It operates a wholly owned subsidiary, 有限会社サポートセンター, established in 2000. The company has no disclosed parent, no private equity or venture capital backing, and is led by representative director 埣山 大 (Dai Mineyama). It functions as an independent (\u72ec\u7acb\u7cfb) vendor-neutral advisory plus implementation partner rather than a product company, with its principal proprietary technology asset being the みまさか販売管理 custom system and the EZ販売管理 subscription product.

Emerging players

• Money Forward, Inc. Japanese cloud SaaS provider offering accounting, payroll, expense, and finance software to SMEs. Competes directly with the on-premise systems Business Support resells and represents a structural threat to the traditional SI/dealer model.
• freee K.K. Cloud-native Japanese SaaS provider of accounting, HR, and payroll software for SMEs. Competes with Business Support's accounting/payroll products (PCA, Oken) on a direct-to-customer cloud basis, particularly threatening traditional on-premise dealer models.

Broad incumbents

• USEN-NEXT HOLDINGS: Japanese conglomerate providing IT, network, payment, and business solutions to SMEs and retailers. Comparable in targeting SME digitalization needs across multiple verticals, with similar bundled-value proposition combining software + hardware + services.
• Canon Marketing Japan: Major Japanese IT solutions and office equipment distributor serving SMEs and enterprises. Comparable in bundling office hardware (MFPs, IT equipment) with IT solutions and software services, with similar diversified regional sales model.
• Ricoh Japan: Japanese office solutions and IT services provider with deep SME coverage. Comparable in offering combined hardware (printers, network) + software (document management, workflow) + services to Japanese businesses, with regional sales presence.
• Future Corporation: Mid-cap Japanese IT services firm providing consulting, systems integration, and packaged software distribution to mid-market and enterprise. Comparable as a multi-vendor IT integrator/reseller serving Japanese businesses, though significantly larger and more diversified than Business Support.
• Nihon Business Systems (NBS): Large Japanese IT solutions provider with deep coverage of business management systems, IT infrastructure, and BPO services. Overlaps with Business Support as a multi-vendor systems integrator for Japanese SMEs and mid-market firms, though with national reach.
• OBC (Ohba Computer Business): Major Japanese accounting and ERP software publisher whose products compete head-to-head with CASIO Rakuichi, Oken, and PCA — the very brands Business Support resells. Comparable as a foundational enterprise software provider in the same SME ERP/accounting category.

Others

• Rakus: Vendor of 'Rakuraku' series (Rakuraku Meisai, Rakuraku Seisan, Rakuraku Hanbai) — a key software line Business Support resells and implements. Comparable as a Japanese SMB-focused SaaS publisher targeting similar SME pain points (e-filing, expense, sales) and a partnership-driven distribution model.
• Cybozu: Major Japanese SaaS vendor of kintone, which Business Support implements. Comparable as a Japanese collaborative/no-code platform vendor targeting SME workflow digitalization, with overlapping customer profiles.
