The Big Picture The latest episode of Shōgun, "The Eightfold Fence," has a lot of bloodshed, but it also introduces a very interesting Japanese concept. John Blackthorne , Toda Mariko , and Usami Fuji have all found themselves in an interesting situation after a decision by Lord Yoshii Toranaga puts them living in the same house, with Fuji as Blackthorne's consort.
The eightfold fence is a coping mechanism that consists of compartmentalizing feelings, allowing them to separate personal and professional views, as well as deal with feelings and how they approach challenges in life. People often have to do things they don't necessarily agree with, so the eightfold fence allows them to carry out whatever order they have without compromising their position, while also retaining their views on the subject.
Fuji Isn't the Only One With a Powerful Eightfold Fence In 'Shōgun' Close According to Mariko's explanation, it makes sense that Fuji would require a powerful eightfold fence. In Episode 1, "Anjin," her husband, Usami Tadayoshi , offends the honor of one of Lord Toranaga's political rivals in the Council of Regents and commits seppuku while also taking the life of the couple's infant child as a way of atoning for almost initiating a war.
