The National Research Institute for Cultural Properties, Tokyo has been conducting an archaeological project at Ak Beshim (Suyab) in the Chuy Valley, Kyrgyz Republic since 2011. This paper provides preliminary results of the project`s first three seasons from 2011 to 2013. The excavations revealed a Qarakhanid main street and several houses along the street in the center of Shakhrsitan of Ak Beshim. This layer is dated by radiocarbon to the late 10th century. According to historical documents, the region was Islamized in the middle of the 10th century, so this layer provides relevant cultural materials for studying Islamization in this region. Radiocarbon dating also suggests that Ak Beshim was abandoned in the late 10th century, 200 years earlier than previously believed. Reasons behind the abandonment of Ak Beshim are considered at the end of this paper.
