Tokugawa Iemochi (1846–1866) was the fourteenth shōgun of the Tokugawa shogunate and ruled from 1858 until his death. His reign came during the turbulent final years of the shogunate, when Japan faced growing Western pressure and serious internal political conflict.

Tokugawa Ienari (1773–1841) was the eleventh shōgun of the Tokugawa shogunate and ruled from 1787 to 1837, making him the longest-serving Tokugawa shōgun. He was a great-grandson of the eighth shōgun, Tokugawa Yoshimune.

Matsudaira Nobuyasu was only twenty years old when his father ordered him to commit seppuku. The reason was not a defeat in battle, but a crisis inside the Tokugawa family that had become too dangerous to ignore.

The anime adaptation of Sekiro: Shadows Die Twice, titled Sekiro: No Defeat, will hit Japanese theaters on September 4, 2026, for a three-week run.

Arato Castle was built in 1524 by the Yamada clan under the orders of their overlord, Murakami, as a small mountain fort. Over time, it gained strategic importance and became a focal point in the conflict between two famous daimyō of the Sengoku period — Takeda Shingen and Murakami Yoshikiyo. This conflict turned the castle into one of the key fortifications in the struggle for control over Shinano Province.

Tatsuno Castle is not a single fortification but rather a complex consisting of two parts: a mountain fortress located at the summit of Mount Keirozan and a flatland-mountain castle situated at its base. The mountain stronghold was built around 1499 by Akamatsu Murahide. During the Muromachi period, the Akamatsu clan was an influential family that, at the height of its power, controlled the provinces of Settsu, Harima, Bizen, and Mimasaka. Murahide’s ancestors were directly involved in the events of the Genkō War in the 14th century and in the subsequent establishment of the Ashikaga shogunate. However, by the 15th century, due to the process of gekokujō, the clan began to lose its position under pressure from rising families, including their former vassals—the Urakami and Bessho clans. In addition, the Akamatsu faced constant pressure from the Amago clan of Izumo Province.
