Popis:	The hook-shaped sand spit at Notsukezaki is the longest (26 km) spit in Japan. The spit is located down-drift of the Shibetzu River. Beach erosion became severe in the 1960s after the construction of the Shibetsu Port updrift of the sand spit. The breakwater of the port intercepted longshore sediment transport. The deposited sediment up to 20,000 m3 has been dredged every year. The dredged sediment has been placed on Sections I and II on the spit. In addition, 39 groins of 35 m length were constructed from 1995 to 2015 in order to protect fishing facilities on the spit.
