Japan is kind of strange country, Japanese goes to shrine(Shinto) on new year day, and funerals are at temple(Buddhism), and celebrating Christmas(Christianity). There are a lot more strange things in Japan.
Japan has more than 2000 letters. We have hiragana(ひらがな), katakana(カタカナ), and kanji (漢字). They import kanji from China, so we can understand some kanji's mean in China.
