IPv6 Ready


Okinawa's total communications provider, born in 1991 and raised by the voices of the people.

The Okinawa Discussion Group, established in October 1990 as a vehicle for businessmen of Okinawa and mainland Japan to work together for development of Okinawa, announced its intention to establish a portable phone company. Funded by DDI and other major firms, Okinawa Cellular was established on June 1, 1991, to provide portable and car phone services in the Okinawa region.

This is because we have always heeded the call to work "for Okinawa.". Our development is closely connected to this community.
