The varved sediment of Lake Suigetsu (central J apan) provides a valuable opportunity to obtain high‐resolution, multi‐proxy palaeoenvironmental data across the last glacial/interglacial cycle. In order to maximize the potential of this archive, a well‐constrained chronology is required. This paper outlines the multiple geochronological techniques being applied – namely varve counting, radiocarbon dating, tephrochronology (including argon–argon dating) and optically stimulated luminescence ( OSL ) – and the approaches by which these techniques are being integrated to form a single, coherent, robust chronology. Importantly, we also describe here the linkage of the floating L ake S uigetsu ( SG 06) varve chronology and the absolute ( I nt C al09 tree‐ring) time scale, as derived using radiocarbon data from the uppermost (non‐varved) portion of the core. This tie‐point, defined as a distinct (flood) marker horizon in SG 06 (event layer B ‐07–08 at 1397.4 cm composite depth), is thus derived to be 11 255 to 11 222 I nt C al09 cal. years BP (68.2% probability range).
