The torrent in this page should provide a copy of the manga, "Showa - A History of Japan," that is organized into 4 omnibus volumes with English translations. ComicVine describes it as "A semi autobiographical work, it is Shigeru Mizuki's meticulously researched historical portrait of twentieth-century Japan, juxtaposed with his growing up during the Showa period. It begins from the period leading up to World War II, a time of high unemployment and other economic hardships caused by the Great Depression to time after Japan’s utter defeat in World War II, as a country reduced to rubble struggles to rise again. The Korean War brings new opportunities to the nation searching for an identity. Mizuki's photo-realist style effortlessly brings to life the history of Japan into the realm of the personal, making it palatable, and indeed compelling." This copy was published by Drawn & Quarterly, and scanned by KickTheKitty. I got it from BakaBT. Screenshots from this copy are available at the following link: https://imgur.com/a/B4upaKk
