At present, it is available for validation. If you want to test the user connection latency and you have users connecting from and near Japan (including India, Australia and AsiaPac geos), please create/ use host pool with the validationenv parameter enabled. You can follow instructions here for the same - https://docs.microsoft.com/en-us/azure/virtual-desktop/create-validation-host-pool
You can also check preliminary latency results using our experience estimator - https://azure.microsoft.com/en-us/services/virtual-desktop/assessment/
