The Mesozoic structure of Hokkaido, which is characterized by a wide spread ophiolite sequence unconformably overlain by a Cretaceous flysch sequence, is cut by a north‐south trending metamorphic belt, the Hidaka Belt. This contribution aims to demonstrate that the Hidaka Belt is a wide right‐lateral strike‐slip shear zone. The movement is contemporaneous with the metamorphism and the magmatism of Oligo‐Miocene time.
