@Alex-dono-sama : It's a sauvastika. Just like the swastika, it has been used for thousands of years all over Asia and ancient Europe as well . They're used in Hinduism, Jainism, Buddhism, the religions of ancient Greece, Rome, in old Norse etc., so the interpretations vary a lot. In Asia in general , just like the appearance, the sauvastika means the opposite of the swastika. Swastika : sunrise, day etc., Sauvastika: sunset, night.
Edit: Looks like the Japanese calls both versions the same: Manji. So that should be the pronounciation here.
