New in paperback. Hardcover was published in 2017. This book explains how the prime ministerial executive operates under the Abe administration and how it is contributing to Abe's unprecedented policymaking authority. It analyses how reform of central government under Prime Ministers Nakasone, Hashimoto and Koizumi has produced the necessary institutional innovations to allow the prime minister to assert a more authoritative policy leadership, turning Japan's traditional, decentralised and bottom-up politics on its head.
