 note = {We measured the radiocarbon ages of the samples such as molluscan shells, Phragmites and pine leaves collected after 1966 year at Lake Biwa to examine the possibility of freshwater reservoir effects at Lake Biwa. The molluscan shells collected after 1990 year, were hardly affected from the nuclear bomb test, showed 330 -450 ^<14>C yrs older radiocarbon ages than that of the coeval atmosphere, as well as the samples excavated from the Awazu submarine shell midden at the Middle Jomon period. The both age offsets were almost identical, which meant that there were likely to be freshwater reservoir effects at Lake Biwa and supported that the degrees of freshwater reservoir effects might be hardly changed for about 5000 years. In this paper, we discuss about the age differences as follows: 1) between snails and bivalves at Lake Biwa, 2) between northern and southern part of Lake Biwa, 3) between molluscan shells and charred wood, excavated from the Awazu archaeological site.
