Denphone supplied us with a small phone system for our office here in Tokyo. The great service, low cost and high reliability, as well as the significant savings on our international calling charges makes their service highly recommendable.

Safe Harbour K.K.

We would highly recommend Denphone for any telephone system work in Japan. They successfully implemented PBX system for our new Tokyo branch office, on time and on budget. We were very impressed by the service they gave and the low cost.
