A new web application will mainly serve users in Japan.
Reducing network latency is important.
Which Region-selection approach is appropriate?
Consider a Region near the users that also provides the required services, while checking legal, availability, and pricing constraints.
Detailed explanation
The newest Region is not automatically the best fit for users or required services.

Foundation review
Benefit versus implementation
Agility and elasticity describe cloud capabilities; a particular Region or AZ is an implementation choice that must satisfy other constraints.
Availability and proximity
Use multiple AZs for failure isolation and suitable Regions or Local Zones for geographic proximity and latency.
