福島正則
Following the battle of Sekigahara in 1600, Mōri was forced out of the castle, retreating to Hagi in today's Yamaguchi Prefecture. Fukushima Masanori became the lord of Aki and Bingo Provinces (which today make up Hiroshima Prefecture) and of Hiroshima castle. However, the new Tokugawa shogunate forbade any castle construction without permission from Edo; this was part of how the shogunate kept the "daimyōs" from gaining power and overthrowing the shogunate. When Fukushima repaired the castle following a flood in 1619, he was dispatched to Kawanakajima in today's Nagano Prefecture. Asano Nagaakira then became lord of the castle.
