Best Public and ISP DNS Servers in Japan (128 Servers)

Want to test and find out the fastest DNS server for Japan? Benchmark your default DNS against providers like NTT Communications or NTT COMMUNICATIONS, or servers in Tokyo or Osaka. Download the DNSSpeedTester Desktop App to benchmark your default DNS against these providers using UDP, DoH, DoT, and Ping, measuring all results directly from your device for maximum accuracy. Just export these IPs using the Export All button below, or check the boxes next to specific providers for a custom list, and load them into the app! (You can also use the export icon on any individual card). Since these lists primarily contain IPv4 addresses (which use UDP), the Desktop App is required for full compatibility. For testing DoH (DNS over HTTPS), you can import the file directly into the Web App. You can also self-host the app on your own infrastructure to run private tests inside isolated networks. If you ever want to revert your test list back to the original domains and servers, just click Reset to Defaults in the app's settings.

Frequently Asked Questions About DNS in Japan

What is the fastest DNS server in Japan?

Global Anycast providers like Google, Cloudflare, and Cisco OpenDNS are typically the fastest worldwide.

Some of the top providers in Japan include NTT Communications, NTT COMMUNICATIONS, and Kddi.

Which DNS is best for gaming in Japan?

For gaming in Japan, low DNS latency matters more than bandwidth. NTT Communications, NTT COMMUNICATIONS, and Kddi's local resolvers reduce round-trip lookup time compared to routing queries to distant servers. Use the DNSSpeedTester app to benchmark them against your current DNS under load.

What are the most popular DNS IP addresses in Japan?

Based on server availability, NTT Communications, NTT COMMUNICATIONS, and Kddi are among the most popular and widely available DNS servers in Japan.

Can changing DNS increase internet speed?
