In the 1920s, a Japanese landlord named Tokuda Yashichi imposed steep rent increases and forcibly seized delinquent rents on farmland across Haui Island, Sangtae Island, and Hatae Island — collectively known as the "Haui Three Islands" — in what is now Sinan County. As their livelihoods grew increasingly desperate, some young men from Haui Island were forced to cross to Osaka, Japan, to make a living, and in January 1927, a group of Haui Island natives living in Osaka, led by Go Jang-myeong and Choe Yong-do, formed the Haui Labor Youth Association. From February to April 1928, a full-scale tenant farmer dispute unfolded across Haui-myeon.
The struggle of the Haui Three Islands residents did not end there. They continued to resist through refusal to pay island taxes, various lawsuits, and a farmers' cooperative movement, and this fight continued through the colonial period, through liberation, and even into the period of American military government. It was only after the National Assembly issued a decision for compensated restitution that residents were finally able to reclaim their farmland in 1956. That a resistance movement which began over a rent increase continued across generations for nearly 30 years suggests that, for these islanders, land was not simply property but a matter of dignity that had to be defended.
The phrase “360-year struggle” is a memorial framework joining land disputes from different periods, not proof that one organization operated continuously for 360 years. Tenant dispute, peasant organizing, litigation, and land recovery describe different layers. The 1956 outcome was a paid return, not a free grant. Visitors should read dated documents and identify who wrote them rather than turning every period into one heroic story. Haui still requires ferry planning, and the coordinate uses the memorial hall as a verifiable visitor point.
