We aim to unveil dietary history recorded in Neolithic human bone from Janghang site at Gadeok Island, Busan. Excavation of Janghang site at Gadeok Island from 2010 to 2011 is an outstanding discovery in Korean Neolithic archaeology. A large number of human bones (48 individuals) were found at Janghang site, which is the largest-scale Neolithic cemetery in Korea. We extracted human bone collagen from 10 individuals and stable carbon and nitrogen isotope analysis were carried out using carbon and nitrogen analyzer connected to a continuous-flow isotope-ratio-monitoring mass-spectrometer. Although bone histological analysis shows poor preservation state, stable isotope results correspond well with bone collagen quality indicator, which implies that bone collagen reflects lifetime signature. Stable carbon and nitrogen isotope result indicates highly marine- based diet (δ 13 C = -14.5±1.3‰, δ 15 N = 17.4±1.7‰), however the possible input of terrestrial animal and wild plant cannot be excluded. Our isotopic findings provide an invaluable information on Neolithic subsistence economy in this coastal area. In addition, Janghang site shows specific features in burial methods and burial goods. Two different burial methods of arranging bodies are found with extended burial type and particularly high ratio of flexed burial type. There are also burial goods such as pottery. However, there are no significant isotopic differences according to burial methods and burial goods. Although this is a preliminary study on this site, our research will provide important clues in understanding isotopic dietary history of Korean Neolithic people.  :             ,      .
