noun
landlocked parcel; land surrounded by private property with no direct public road access
Legal/real estate term for a plot of land that has no direct access to a public road because it is entirely surrounded by other private land. Compare 裏地 (うらじ), which can also refer to backland or land behind a building.
See also: 裏地
袋地のため、隣地を通らなければ道路に出られない。
Because it's a landlocked parcel, you can't reach the road without crossing the neighboring land.
裏地 can mean 'backland' or 'land behind a building,' and in sense 2 it overlaps with 袋地 as a landlocked parcel, but 袋地 more strongly emphasizes being completely surrounded with no road access.
Compound of 袋 (ふくろ, 'bag') + 地 (ち/じ, 'land' or 'material'). The 'sacking' sense derives from 'bag material,' while the 'landlocked parcel' sense metaphorically likens the enclosed land to a bag.
