Test against Tokyo
Korean users can reach Tokyo, but real latency and routing vary by network. Compare both from your users’ networks before you decide.

Two things to think through.
Korean users can reach Tokyo, but real latency and routing vary by network. Compare both from your users’ networks before you decide.
Korean networks and services have their own peering patterns. Include any local third-party services your application calls in the comparison.
Distances from Seoul to the closest GLWS locations.
Japan
About 830 km away. Physical minimum round trip about 8.3 ms.
Japan
About 1,150 km away. Physical minimum round trip about 12 ms.
Hong Kong

Distances are straight-line between city centres. The minimum round trip assumes light in fibre at about 200,000 km a second and a straight cable. Real routes are longer, so always test from your own audience. For a second site that survives a regional outage, Stockholm is about 7,430 km from Seoul.
A nearby server is only one part of your application.
Compare the route from the audience networks you expect to serve. Test real requests, not only a location label.
