The elegant, multi-storey main towers of Japanese castles, surrounded by massive fortifications, are widely known as symbols of samurai rule. However, the first of these tenshukaku were built only at the very end of the Sengoku period. Most fortifications were built of wood with eart- hen ramparts and ditches exploiting the natural environment.
The second volume of this series details these constructions as well as the fortifications that were affected by major sieges: Fushimi, Tanabe, Otsu and Ueda in 1600, and Osaka in 1614/15. The author explains the sophisticated siege techniques and countermeasures employed by samurai armies of the period, and the Japanese artillery of the time.
