Hagi was one of the new cities which grew from the emerging level of national political stability and economic development emerging from a century of conflict, international contact and the dynamics of internal social change. Following the vacation of the Osaka Castle by the Nishiyama Honganji Kanbei laid out the new Osaka for Toyotomi Hideyoshi in 1586, setting a prototype which acted as a copybook for successive new foundations and reconstructions. The new capital was used by the Mori as a model for both Hiroshima and Hagi. The motivation for Hideyoshi’s choice of the site of Naniwa, subsequently Osaka, differed little from the generations of rulers from antiquity. Mori Terumoto’s occupation of Osaka Castle prior to the Battle of Sekgahara was the subterfuge used by Tokugawa Ieyasu to dispossess him of Hiroshima and his extended domains, and the construction of Hagi began in haste in 1603 on the conclusion of negotiations over the selection of the site.
