Today, this area of south-west Jeju grows vegetables of all kinds – radishes, leeks, cabbages, potatoes and more – but there are still plenty of clues about the wartime role of this flat land.
That tree-topped hillock in the photo below isn’t natural: It covers a man-made shelter. You can go down the steps in the little gap near the right-hand end and emerge at the other end.
The shelter is a relic of the war, and this was an airfield built by the Japanese to defend Japan and from which to launch bombing missions on China. The photo below shows some of the bunkers that remain as well as showing, in the distance, how Sanbangsan rises out of the landscape.
Notes from a Korean island 
That’s a field of potential kimchi just waiting for the sousing!
