Major ISPs in Japan are working hard to prepare, but they are afraid that many smaller ISPs or web-hosting companies may not be doing well and may cause big trouble for global Internet operations.

All Network Information Centers, NICS, where they handle country domain name servers must prepare Y2K ready.
