Summary
Asahi Net, Inc.
isp legacy
ASAHI-NET — Asahi Net, Inc., a long-running Japanese internet service
provider serving consumers and businesses nationwide.
What it's used for
- Fixed broadband internet access — fibre and, historically, ADSL — for Japanese households and small businesses, plus mobile data as an MVNO.
Notable
- A classic eyeball network: most addresses here terminate at subscriber homes, so an IP in this space is a residential user far more often than a server.
- Asahi Net rides on NTT's FLET'S fibre access and on NTT DoCoMo's radio network for its mobile service, rather than owning last-mile infrastructure itself.
Interesting
- The company began in 1990 as a PC-communication (dial-up BBS) service and moved to internet access in 1994 — one of the Japanese providers that made the jump from the pre-web online-service era. It has been publicly listed in Tokyo since 2007.
- Asahi Net is one of the few Japanese ISPs to offer English-language support, which makes it a common pick for foreign residents.
