This thesis studied the relationships between 「Joy」 and the 「Body parts」 in Korean and Japanese language and compared them. It covered the subordinate meanings of 「Joy」, such as 「fun」, 「pleasure」, 「satisfaction」, 「happiness」, 「auspiciousness」,「excitement」, and 「impression」. In general, both Korean and Japanese have similar patterns, yet Korean has more expressions regarding 「excitement」.Categorizing the body parts as a 「head」, a 「torso」 and an 「entire body」, this study has discovered that 「Joy」 can be expressed by 「eyes」, a 「chest」, or a 「whole body」 in both languages. In case of 「physiological phenomenon」, they use 「tears」frequently in order to show 「Joy」. Additionally, in Japanese, there are numbers of the 「usages of eyes; the condition of fine muscle movement」. There are various usages of a 「mouth」 in Korean language. Further studies are planned to define the relationships between 「Emotion」 and the 「Patterns of the Body parts」in both languages.
