In the Kiritappu wetlands of Hmanaka Town, sika deer (Cervus nippon yesoensis) have been observed in kelp drying grounds and caused damage due to dung deposition. Therefore, countermeasures are required, but they cannot be implemented due to a lack of basic information on this species. In this study, we instigated camera traps, spotlight counts, and fixed-point and direct observations to clarify deer behaviors in urban areas or kelp drying grounds. Many deer were observed in urban areas between November and December, and between sunset and sunrise in kelp drying grounds. Similarly, deer numbers were lager in areas where electric fences were absent. Their behaviors in urban areas mainly involved “walking” in kelp drying grounds. Whereas the result “feeding” in the unimproved land. It was hypothesized that deer appearance increased in urban areas during the breeding and winter seasons. Also, deer were commonly seen from around sunset to sunrise, walking or feeding in urban areas. Electric fences are often effective measures against deer entry, but cannot completely block or prevent deer access as roads border these fences. In future research, it is important to investigate sika deer intrusion routes and patterns in areas where electric fences are breached.
