Specialization and Research Interests

• Specialization: Japanese Archaeology (Paleolithic and Jomon Periods), Archaeological Petrology
• Research Interests: While attending a National Institute of Technology (KOSEN), I developed an interest in folklore and subsequently enrolled in the Department of Historical Heritage at Tohoku University of Art and Design. Participating in archaeological excavations led me to major in archaeology. During my time at university, I focused on the quantitative analysis of stone materials used in prehistoric stone tools and their impact on human behavior. After completing my master's degree, I joined a software development company. My interest shifted towards the transition from prehistoric to historic periods. Currently, through tasks such as organizing workflows in software development, I am interested in the formation of tacit knowledge and the processes of human communication.
