Japan's navy beyond a regional role

Is modern Japan's navy an effective regional force?

Yes, and the 2020 assessment sees it becoming more than a regional navy.

In this 2020 assessment, Japan's fleet was already more than an effective regional navy. Its development pointed toward a more powerful force with a role beyond local waters. The claim concerns strategic direction rather than a ship-by-ship readiness test. Regional effectiveness and wider reach are treated as distinct measures of naval power.
