A 1910–1918 colonial survey that measured and registered Korea's farmland and building plots, creating modern title records and tax rolls.
See it on the Korean History map →What happened
The Government-General's Land Survey Project (토지조사사업) mapped plots, fixed boundaries and recorded one legal owner for each, who had to report the claim within a set period. It replaced overlapping Joseon-era rights with exclusive private ownership and a land tax based on assessed value. Royal, government and unclaimed land became state property; some later passed to the Japanese-run Oriental Development Company and Japanese settlers. Tenants' customary cultivation rights were not recognized.
Why it matters
It created the property-rights system modern Korean real estate still builds on, and became a central case in the debate over what colonial rule did to Korea.
Think of it like
Like a countrywide title and cadastral survey that issues clean deeds for every parcel, but decides along the way whose claims count.
How we know
The survey's own land registers and cadastral maps, which still underlie some Korean property records, plus archival studies since the 1990s comparing them with older Joseon documents.
Still debated
How much land Koreans lost: the older view says vast tracts were seized; archival studies since the 1990s found far less, but its role in tenant hardship is still argued.

▸Japanese colonial rule of Korea carried out Colonial land survey projectWell documented
The connection
One of the Government-General's first big projects, the survey gave the colonial state an accurate tax base and a land market readable by Japanese investors. It ran alongside forest and urban surveys and laid the legal basis for the land tax that funded much of early colonial government.
When and how
Run by the Provisional Land Survey Bureau, founded in 1910, across all of Korea's provinces until 1918.
How we know
The 1912 Land Survey Ordinance, the bureau's reports and registers, and colonial budgets showing land-tax revenue rising after the survey.
Debates and open questions
Whether its main purpose was modernizing property rights, raising revenue or easing Japanese land acquisition is debated; it may have been all three.
▸Colonial land survey project is debated as a root of Miracle on the Han RiverDebated
The connection
The 'colonial modernization' school argues the 1910–18 survey gave Korea clear land titles and a modern cadastre (official land registry), which, with colonial railways, banks and bureaucracy, laid groundwork for later growth. Critics reply that the survey served colonial revenue and Japanese landowners, and that postwar land reform, war destruction and US aid matter far more.
When and how
Debated mainly since the 1990s among South Korean, Japanese and Western economic historians, including Lee Young-hoon and Carter Eckert on one side and 'colonial exploitation' scholars such as Shin Yong-ha on the other.
How sure are we?
Uncertain. Land records and colonial output estimates exist, but the link is interpretive. South Korea still relied on colonial-era cadastral maps when a nationwide resurvey began in 2012.
Debates and open questions
How much colonial institutions survived war and land reform, and how much land the survey actually took: the old textbook claim of about 40% is now doubted by many historians.
