Japan's Aegis vessels and a possible second batch

What is the assessment of Japan's Aegis-equipped vessels under construction?

Their role differs from the Type 055's despite similar size. The first pair accommodates radar ordered for land use, while a possible later pair could be designed around shipboard requirements.

Japan is predicted to want four Aegis-equipped vessels eventually, making differences between the two possible pairs worth considering. Their size invites comparison with Type 055, though their intended roles differ in this assessment. The Japanese ships serve national strategic security, while Type 055 projects national status and power. The first Japanese pair must accommodate large radar systems originally ordered for land use. A later batch designed around shipboard requirements could therefore differ. The additional pair remains a prediction.
