Average Internet Speed in Japan

Internet in Japan: what the data shows

At a median 57.9 Mbps download, Japan sits comfortably in the top quarter of the table: #28 of 119 ranked countries, 71% above the global median of 33.9 Mbps. The world's fastest median belongs to the United States at 144 Mbps, about 2.5× faster.

Uploads run nearly symmetric with downloads (50.2 vs 57.9 Mbps), the signature of fibre-to-the-home lines carrying much of the traffic. Median latency is 56 ms. That works for streaming and browsing, though competitive gaming and video calls will feel it.

The provider table stretches wide: So-net leads the measured ISPs at 262 Mbps, 4.5× the national median. A spread like that opens up where full-fibre networks compete against legacy copper and cable, so which network serves your address changes more than any plan upgrade.

Desktops test faster than phones here (83 vs 44 Mbps): home Wi-Fi and wired links outrun the mobile networks that carry 64% of tests. By operating system, Mac OS devices record the quickest median (101 Mbps) while Android sits at 39 Mbps, usually a proxy for the networks and hardware each platform rides on rather than the software itself.

Tests from Japan most often reached the Tokyo test server (73% of the top-server mix), so the figures reflect the routes everyday traffic actually takes. Every number on this page is a median of single-stream browser tests from the H1 2026 window: Real-World Speed, measured on the open internet rather than inside an ISP's own network. It reads lower than peak-rate tests by design, and every country is measured with the same ruler.
