You can see the teaser trailer for Yakuza Ishin at the 4:20 mark. The video makes a comparison between the historical Ryoma Sakamoto, and the way more badass in-game version.
So, coming from this, we can infer that the game is probably based around Sakamoto’s life as it was historically. Ryoma was a key figure in the attempt to overthrow the Tokugawa Shogunate during the Bakumatsu period in Japan.
