Swastika
I know a Japanese teenaged girl. Every time I see her she has two black swastikas drawn on her hands with a black magic marker. I asked her why. She said it was for luck and for strength.
The "manji" swastika is the reverse image of the Nazi "hakenkreuz," hooked cross swastika, which was the symbol of the Nazi Party in Germany, and later of the Third Reich. More accurately, the Nazi symbol is the reverse image of the ancient religious image. It is not uncommon in Japan and other Asian countries to see the "manji" decorating temples and shrines, and to mark temples and shrines on maps. When Western foreigners first see it they might feel surprised or even shocked, but it does not carry the stigma that it carries in the West.
The swastika (as a character 卐 or 卍) is an ancient religious icon used in the Indian subcontinent, East Asia and Southeast Asia, where it has been and remains a sacred symbol of spiritual principles in Hinduism, Buddhism and Jainism. In the Western world, it was historically a symbol of auspiciousness and good luck, but in the 1930s, it became the main feature of Nazi symbolism as an emblem of Aryan race identity, and as a result, it has become stigmatized in the West by association with ideas of racism, hatred, and mass murder.
