EP35: Connectivity in Japan – part I

The number of Internet users in Japan is expected to increase to 116.4 million by 2026. With many of Japan’s businesses at the cutting edge of technology, there is a demand for scalable connectivity to connect local businesses to a global network of customers and partners. How is Japan’s Internet market developing? What are the traffic trends? What role does organizations like JPNAP and APIX play in this region? And what can be done to mitigate connectivity outages following natural disasters like earthquakes?

In this episode, Mattias Fridström is joined by Katsuyasu Toyama, COO at JPNAP, the biggest Internet exchange in Japan, for a discussion on the above.
