As [[Japan]] and the [[Korean peninsula]] became politically centralized in the 7th century AD, those societies adopted Chinese grid-planning principles in numerous locations. In Korea, [[Gyeongju]], the capital of [[Unified Silla]], and [[Shangjing Longquanfu|Sanggyeong]], the capital of [[Balhae]], adapted the [[Tang dynasty]] Chinese model. The ancient capitals of Japan, such as [[Fujiwara-kyo|Fujiwara-Kyô]] (AD 694–710), [[Nara, Nara|Nara]] (Heijô-Kyô, AD 710–784), and [[Kyoto]] (Heian-Kyô, AD 794–1868) also adapted from Tang's capital, [[Chang'an]]. However, for reasons of defense, the planners of [[Tokyo]] eschewed the grid, opting instead for an irregular network of streets surrounding the [[Edo Castle]] grounds. In later periods, some parts of Tokyo were grid-planned, but grid plans are generally rare in Japan, and the [[Japanese addressing system]] is accordingly based on increasingly fine subdivisions, rather than a grid.

The grid-planning tradition in Asia continued through the beginning of the 20th century, with [[Sapporo]], Japan (est. 1868) following a grid plan under American influence.
