As you already know, yuzuru takes many good luck charm; stone bracelets(given by his mother), cross pendant, bangle(gifted by Plushenko), misanga (presented by famous Japanese women singer ”Mai Kuraki”)that I glance over. And he turns off the cross before he performs the program since 2007-2008season(propably at least).
But, these cross pendant and turn off the cross dosen’t mean religiously so deeply.
Of course, these charms are very precious gift for him ,though.
It is difficult for even for me(ourseleves) to explain the religion of the Japanese. But I will try to explain.
For many Japanese, we cereblate New Years in the style of Shintoism, weddings in Christianity, and funerals in Buddhism.
As you know, most of the European people and the American people have their religion. And their religion is mainly Christianity.In Saudi Arabia, or in Africa, many people believe in Allah.
Comparing with them, the Japanese seem to not to have deep religious feelings.(
Of course, some Japanese believe in Buddhism, and some believe in Shintoism, or some even believe in Christianity. )
I think, however, Japanese do have their own unique religious feelings. We Japanese have syncretic religious feelings(see; Religion in Japan at Wikipedia), and they do not seem for many foreign people to be the deep religious feelings.
It is not strange that one Japanese prays to Buddha and at the same time prays to Shinto gods. This doesn’t mean lack of religion in the Japanese. This is the typical form of Japanese's religion. It is often difficult for Japanese themselves to say which god they believe in, or which spirit, or holy being, they believe in. But most Japanese believe in something religious entity which is, however, difficult to name correctly. And you should know that this is the style and existing form of the Japanese religion.
