Use cases
Localisation and regional QA
Test how your product behaves for a user physically located in Japan.
The problem
Region detection, currency, payment methods, legal notices and region-locked content all depend on the visitor's IP. Testing from your office abroad exercises the wrong code path, and bugs reach Japanese users first.
How a Japanese residential IP solves it
Route your browser or test suite through a Japanese residential IP and the application makes exactly the decisions it would make for a real customer in Japan.
