Story : Shogun is the story of the Great Samurai who in 1600 reunified Japan, then divided into a myriad of clans, becoming the undisputed leader of the country, after the bloody battle of Sekigahara. His name was Ieyasu Tokugawa, and his descendants would inherit this absolute power until the last decades of the 19th century, when Japan emerged from its long isolation and opened up to the modern world. The Speciali SuperQuark went to various ancient cities of Japan to tell this story, using the fiction produced by the BBC on the life of the famous Samurai. Alberto Angela followed the construction of a katana, the famous samurai sword, made by one of the very few craftsmen able to replicate the ancient procedures. In the studio, Prof. Franco Mazzei will talk about the influence of what has been defined as the "Japanese Middle Ages" on the traditions and values ​​of today's Japan.
