DNS Landscape in Japan
Japan has some of the fastest internet speeds in the world and excellent DNS infrastructure. Google DNS performs particularly well in Japan due to Google's strong peering with Japanese ISPs and points of presence in Tokyo and Osaka. Cloudflare also has a strong presence but Google has the edge in most Japanese locations.
Google DNS (8.8.8.8) averages 10 ms in Tokyo. Cloudflare DNS (1.1.1.1) averages 12 ms. Quad9 averages 20 ms. OpenDNS averages 24 ms. Japanese ISP DNS (NTT, KDDI, SoftBank) averages 8-18 ms depending on the provider and region.
