We Go Beyond
Headquartered in Japan’s Setouchi region, the centre of thecountry’s shipbuilding industry, Nakashima Propeller is amanufacturer of marine propulsion equipment boasting a leading
share in marine propellers.
Having started as a foundry for fishing boat propellers, thecompany has continued to pursue innovation in the capabilityof propellers to deliver security, safety and comfort. It will becelebrating its 100th anniversary in 2026.
A ship’s optimal state is found when it is viewed from thepropeller, the centre of propulsive functions. With this fresh
perspective, Nakashima Propeller seeks to offer a full range of■ OUR SERVICES
Nakashima Propeller designs and manufactures marine propellers(FPP and CPP), thrusters, energy-saving devices for the stern and
CFRP propellers.
We also offer a full range of after-sales service, including repairof damaged propellers, edge modification, fuel-saving polishing,support of propulsion equipment for ships in operation andoptimisation of propulsion performance for fuel efficiency.

Issue 9*We provide propellers for ULCS, VLCC, VLOC, VLGC, LNG/LPG-carriers, PCC, cruise
ships, working boats, coastal vessels, research vessels and coast guard vessels*Our services satisfy requirements for all major classification certificates (including
ice-class)services catering to each ship’s entire life
cycle while achieving fuel efficiency to
reduce the burden on the environment.
Nakashima Propeller works to contribute to
