Since his return to power last December, Prime Minister Shinzo Abe's slick communications team has tried to make buzzwords and catchphrases a hallmark of his administration, using them to frame debate and capture public attention, especially on controversial policies.

First came "Abenomics," the label for his unorthodox strategy of ending deflation and reviving the economy, followed by the phrase "proactive contributor to peace," which was used to define his vision for the Japanese military. Most recently, the Abe government has become synonymous with the term "secrecy law."

In the year that has passed since Abe became prime minister, he has been more active in reworking security and defense policy, an issue that has been close to his heart since his first brief stint in office from 2006 to 2007.
