Wamnet

What Wamnet does

Wamnet (日本ワムネット株式会社 / Wamnet Japan K.K.) is a Tokyo-headquartered Japanese provider of enterprise file transfer, sharing, and storage services, founded in 1999 and operated as a privately held joint venture majority-owned by Sumitomo Corporation, with NTT Communications as a co-investor. The company serves large Japanese corporations, listed companies, and government agencies, and its flagship GigaCC platform has been in continuous operation since 2002, holding the No.1 market position in Japan's enterprise online storage segment per ITR Market View and BCN Bizline (2013 results). Wamnet explicitly self-describes its business as a "stability period" (安定期) with share-top brand status.

The product portfolio is anchored on the GigaCC platform, which spans GigaCC ASP (cloud-hosted inter-company file transfer and sharing), GigaCC OFFICE (on-premises software for enterprises preferring in-house servers), and modules including OKURN, GigaCC View (view-only sharing), and SHARERN (cloud storage for NAS/file-server migration, launched Feb 2023). The DIRECT! EXTREME service provides large-capacity file transfer with automation via VDX, VAD, and the DEX AutoLink cloud-storage integration (Oct 2024). Other products include MultiPortFAX 4 Pro (multi-line FAX server for enterprise systems), Commucatto (CATV-industry communication portal launched Aug 2022), and WS2 (powered by GigaCC). Technical features include ISO/IEC 27017 cloud security certification, JIIMA electronic transaction software legal certification (Nov 2024), WebAPI for system integration (Nov 2024), Microsoft Office for the Web collaborative editing (Jul 2024), OPTiM ID+ SSO (Apr 2022), electronic watermarking, CDN/site acceleration, and mobile (iOS) applications. An RPA Solution line extends the platform into workflow automation.

The business model combines recurring cloud subscriptions (GigaCC ASP, DIRECT! EXTREME, SHARERN, OKURN, support plans including 8-hour and 4-hour SLA tiers), one-time software licenses (GigaCC OFFICE, MultiPortFAX 4 Pro), and industry-specific services. Pricing is mostly quote-based for enterprise deployments, with one published tier at 75,000 yen/month (GigaCC トラスト便, 20 accounts). Distribution is enterprise-focused, mixing a dedicated Solutions Sales Department (ソリューション営業部) with channel partners such as Assist Co., Ltd. and licensed sales partners for DIRECT! EXTREME, supported by active presence at Japan IT Week, Cloud Computing EXPO, Content Delivery Expo, and Information Security EXPO. Named enterprise customers span manufacturing (Asahi Kasei, Dainippon Printing), media (Toyo Keizai), food service (Izutsu Maisen), retail cooperatives (Co-op Deli), agricultural cooperatives (Tochigi Prefecture), medical IT (Image One), and funeral services (Heiankaku), and the company has been selected as a supplier for the 2025 Osaka-Kansai Expo.
