Mogami Yoshiaki is one of the new 5 non-playable characters in Sengoku BASARA 3 (Sengoku Basara: Samurai Heroes in NA). He is playable in its expansion, Sengoku BASARA 3 Utage.


Mogami Yoshiaki, the leader of the Mogami clan that rules Dewa Province. Often known as "the Noble Fox of Dewa", though he is referred to as a weasel in the overseas release. He thinks of himself as a great and smart nobleman. He appears as a thin and tall man, often holding a cup of tea, with a rather wacky moustache. While he is Masamune's maternal uncle, the two of them rarely hint at it, though Yoshiaki refers to him as "Masamune-kun".

He often tells his opponents that he has prepared tea, as a welcoming to their visit. However, he also has a habit of not remember his opponents names and talks down to them as he attacks.

Yoshiaki will always join the Eastern Army, no matter which story is being played. To do this, he appeals to Ieyasu and forces Maeda Toshiie to ally with the Eastern Army as well by kidnapping Toshiie's wife Matsu in order to ensure his compliance. When the player fights Yoshiaki at his stage in Hasedo and defeats him, they will also free Matsu, provided they are not playing Masamune's paths.

Yoshiaki is one of the eight characters to receive their own story in Sengoku Basara 3 Utage.

  • 超壮絶復活不死鳥成り (Chō sōzetsu fukkatsu fushichō nari): Yoshiaki fakes his death, then after a flash of light shines on him, he jumps into the air and rapidly slashes, making a fox symbol, then it blasts enemies into the air.
  • 超偉大我輩氷像定礎 (Chō idai wagahai kōri-zō teiso): Yoshiaki summons an ice sculpture and begins to rapidly jab at it, making an ice statue of himself, while attacking enemies in unison. After he takes a bow, the ice scatters onto enemies.

Historical InformationEdit

Mogami Yoshiaki (最上義光, February 1, 1546 - November 29, 1614) was a daimyō of the Yamagata domain in Dewa Province, in the late Sengoku period and early Edo period. He was the first son of Mogami Yoshimori, and succeeded his father as daimyō of Yamagata. He also was known as "The Noble Fox of Ushu/Dewa" and has a mixed reputation in fictional sources. He is sometimes be depicted as a wise ruler or as a villainous man who didn't fight at all.

When Toyotomi Hideyoshi came to power, Yoshiaki submitted to his rule, but later became a supporter of Tokugawa Ieyasu following Hideyoshi's death. He was known to hate the Toyotomi due to the fact that Hideyoshi ordered the execution of Yoshiaki's teenage daughter when purging his nephew Toyotomi Hidetsugu, whom Yoshiaki's daughter was engaged to.

In 1600, he battled Uesugi Kagekatsu, an enemy of Tokugawa's, alongside his nephew Date Masamune. He aided in Date's siege of Shiroishi, and was then attacked in his own home castle of Hataya. Later that year, Mogami and Date supported Ieyasu at the famous battle of Sekigahara, after which Mogami's domain was expanded to 520,000 koku in return for his loyal service. This made the Yamagata domain the fifth largest in Japan at the time, excluding the land held by Tokugawa. He died at Yamagata Castle in 1614 at 68 years old.
