Order on Land Plot and Residence Restrictions・house of peasants

The reports of a Chinese envoy (sapposhi) who visited in 1534 mention a “palace and temple are in good condition but only two-or-three private houses with tiled roofs, the others being plain buildings (dokaiboushi), not endurable even with the wind” (sapposhi = mission sent from China in order to give a kingship to Ryukyu)
During the era of the Ryukyu Kingdom, there were limitations on the land and houses that individuals could own according to rank. In fact, a prohibition on clay tile roofing was imposed in 1691, restricting the usage of clay tiles to the noble and warrior classes. The order lasted until the Haihan-chiken (abolition of feudal domains and establishment of prefectures) in 1871. Following a land survey in 1737, the overall size of houses and their floor space (measured in tatami mats) were also limited by rank.
