Kaiju (怪獣 kaijū?) is a Japanese word that literally translates to "strange beast." The word has been translated and defined in English as "monster" and is used to refer to a genre of tokusatsu entertainment. Kaiju films usually showcase monsters of any form, usually attacking a major Japanese city or engaging another (or multiple) monster(s) in battle.
4. MOTHRA - Bad ass giant flying moth. One of the original Kaiju to grace our television screens. Why are moths hairy? That always creeped me out. Ever kill one? It's like it turns to dust or something.
