This study is about the change of Inuit traditional culture. Inuit has their specific culture due to the Arctic’s harsh environment. But recently, because of the climate change and newcomers, traditional culture has changed. Hunting, the base of Inuit’s traditional culture decreased and was getting hard. And shelter and transportation for hunting has been modified. According to the change of hunting, food and adoption culture also changed. Inuit is in a situation to consume junk food and processed food instead of fresh food. Those food induce many problems to Inuit including health. And Inuit trade the food, not share. It means the community spirit weakened. Reduction of the importance of IQ (Inuit Qaujimajatuqangit) and the role of the senior also contributes to the weakening of community spirit. Inuit adopt non-Inuit child and adopt the child according to the law. It makes Inuit difficult to adopt child. As a result, climate change and newcomers makes today’s Inuit culture. Therefore, we have to know climate change and newcomers to understand the culture of the Arctic and residents.
