Kosuge Slip Dock, Maritime industrial site in Nagasaki, Japan
Kosuge Slip Dock is a ship repair facility in Nagasaki, Japan, listed as part of the UNESCO World Heritage Site, and it consists of a Western-style slipway with railway tracks and a brick engine house that once powered the hauling mechanism. The slipway runs from the water up a slope to the land, where vessels could be worked on out of the sea.
The facility was built in 1869 through a partnership between Japanese entrepreneurs and Scottish merchant Thomas Blake Glover, making it Japan's first joint venture in ship repair. It took shape during a period when Japan was starting to open up to foreign knowledge and new industries.
Kosuge was the first place in Japan where ships were repaired on dry ground using a Western-style slipway, and the tracks that guided vessels out of the water are still visible today. Walking along them gives a clear sense of how this method worked in practice.
The site sits along the waterfront in the port area of Nagasaki and can be reached from the city center in roughly 20 minutes by bus or taxi. Sturdy shoes are a good idea since parts of the visit involve walking on uneven ground near the old tracks and slipway.
The brick engine house on the grounds is one of the oldest masonry buildings in Japan, constructed with locally made bricks under Dutch guidance. It still stands in its original form, and visitors can examine the brickwork up close on both the interior and exterior walls.
