Iwafune no Ki

Iwafune no Ki

Iwafune no Ki (磐舟柵) also known as Iwafune no Saku was a type of ‘Saku‘ (fortified frontier) in the old Province of Echigo, modern day Niigata Prefecture, close to the city of Murakami. It was established in 648AD as part of a campaign against the Ezo tribes in northern Honshu.

It is thought to have fallen into disuse around 708AD alongside Nutari no ki. Remains of this site were thought to have been found in 1957 near to Iwafune Shrine.1
