Kannet Communication & Support

What Kannet Communication & Support does

Kannet Communication & Support is the trading brand of Kan'etsu Network System Inc. (関越ネットワークシステム株式会社), a privately held regional internet service provider headquartered in Numata City, Gunma Prefecture, Japan. The ISP business began in September 1996 under parent Takenouchi Denki (株式会社たけのうち電器) and was formally spun off as a separate corporation in June 2000. The company serves individual consumers and households in Gunma Prefecture, offering fiber optic broadband (Kannet Hikari, including a 10Gbps tier launched April 2026), tiered course plans across dial-up, ADSL, and FTTH, and a discontinued 050-prefixed IP telephone service.

The core technology stack relies on NTT East Flets fiber infrastructure delivered as a reseller partnership, with IPv6 service over IPoE and IPv4-over-IPv6 (DS-Lite) bridging for legacy access. Email is bundled free of charge with all plans, featuring built-in virus checking and spam filtering. Adjacent services include domain registration (international and JP regional domains including .gunma.jp), shared and dedicated rental server hosting, shared and dedicated SSL certificates, anti-spam delivery rule settings, and resale of NTT supplementary services such as Flets options and remote monitoring.

Revenue is generated primarily from recurring monthly subscription fees across connectivity plans and add-on services (hosting, domains, SSL), supplemented by bundled free email and an off-core tourism portal for the Minakami Kogen area. Go-to-market is direct-to-consumer via the company's website (enrollment forms at ecw.kannet.ne.jp), phone support, storefront/walk-in support at the Numata headquarters and Maebashi satellite office, and on-site (出張) visits, all within a single-domestic geographic scope. Capital stands at ¥10,000,000 with reported headcount of 1-10 and no disclosed external investors or funding rounds.
