Based on the Best Selling 1975 historical fiction novel by James Clavell; Shōgun is set in 1600 Japan. With the death of the Taiko, and his heir being only 11 years old, Japan is ruled by a council of five reagents from the five most powerful clans. Portugal has established trade with Japan through the discovery of the Straight of Magellan and the Catholic Church tightly controls that trade with Japan and uses it to enrich itself and meddle in "local" politics. Japan stands on the brink of war as the five reagents scheme and plot amongst themselves. A mysterious English ship is found adrift near the fishing village of Ajiro, setting into motion events that will change Japan forever.
I just finished watching this series and I cannot recommend it enough. The production, writing, acting, and story are all top-notch. I've read the novel and seen the NBC miniseries growing up. In fact, I watched it with my dad and those are some of the best memories I have with him. I still have his copy and like most copies that have survived to a certain age, it has collapsed into two separate but equal length halves. The novel is kind of infamous for doing that. Seriously, it's 1210 pages long. Worth reading, before or after you watch either of the series available. If you like Japanese samurai movies or historical fiction, you should give this version a try.
If you do watch this, please note that there are two versions. An English dubbed version, where the spoken Japanese is dubbed, and a subtitled version. I recommend the subtitled version as it adds a little more depth to the main character and story.
Edit: Forgot to mention that you need the Hulu/Disney+/ESPN bundle if you want to watch this on Disney+.
