What Is the Symbol on Manji's Back?
Readers meeting Blade of the Immortal for the first time often stop at the mark on the back of Manji's kimono. The character is called Manji, written with the single character 卍, and he wears that character as his crest. The symbol's name in Japanese is simply manji, and in Japan it is an everyday sight with an everyday meaning: it is the mark used on Japanese maps to show the site of a Buddhist temple.
The manji belongs to a family of swastika symbols used across Eurasia for millennia, in Buddhism, Hinduism and Jainism, as an emblem of auspiciousness, peace and harmony. In its Buddhist use in Japan it is drawn facing left, as Manji wears it. The emblem adopted by the Nazi party in the twentieth century is a different object with a different history: right-facing and tilted, drawn from the same ancient stock but made into something else. Samura's mark is the temple one, worn by a character named after it, in a story set centuries before the twentieth century existed.
