Question

Why did the JMSDF begin building its first Aegis guided-missile destroyers in the late 1980s?

Short answer

The technology had become viable, the Arleigh Burke program offered a parallel model, and Aegis directly supported Japan's need to protect territory and maritime communications.

Notes

Japan began its Aegis destroyer program when the technology and supporting systems had become viable. The Arleigh Burke program developed in parallel and offered a model to observe. The JMSDF's central tasks were protecting Japan's territorial integrity and sea lines of communication. The emerging weapons threat made this combination of sensors and air defense relevant to those tasks.
