Recently, Halloween is getting popular in Japan. Although many of Japanese are not Christians. Many shops sell costumes, decorations, foods, and so on for Halloween.
Japanese traditional sweets are decorated with a ghost, too.
As an ingredient, pumpkin is used.

Traditionally, Halloween is celebrated by children dressing up in frightening costumes. But I’ve heard that many adults are recently disguised in costumes, too. Also costumes are not only frightening things- such as anime and game’s characters. In Japan, the situation is same. So you can see many anime characters on streets on October 31.
