本研究以歷來探討不多的台日移動兒（除台日混血兒外，另含華僑、因父母工作或留學之故12歲前曾長住日本至少4年的人）15人為對象，進行訪談，探詢他們語言發達的狀況及認同。此次受訪者大多對擅長中日雙語持肯定的態度，且大多的受訪者均能自由運用中日雙語。但在認同方面能迅速明確回答的人卻不是很多。這或許與受訪者當初在學校學習近代史的經驗狀況以及教師、同學或鄰居等周遭人的態度有關

This paper interviewed 15 Taiwan-Japan ＂Idouzi＂ (Besides Taiwan-Japan half, also including overseas Chinese, and those stayed in Japan by more than four years because of family issues) on the status and identification of language development. Most interviewees are able to handle both Chinese and Japanese and are positive to have such a capability. However, few of them are clearly and precisely reply on the questions about identification, likely being attributable to the experience on contemporary history learning and the attitude of surrounding people
