Why does Hokkaido, Japan, not have counties but separate roads?

Hokkaido's administrative structure, which lacks the traditional county (*gun*) system found in other Japanese prefectures and instead utilizes a separate "road" (*dō*) system, is a direct consequence of its distinct historical development and geographic scale. Unlike the main island of Honshu, where counties were ancient administrative units that evolved from classical *kuni* (provinces), Hokkaido was not fully integrated into the Japanese state until the modern Meiji era. Following the formal establishment of the Hokkaido Development Commission (*Kaitakushi*) in 1869, the island was systematically surveyed and organized for settlement and defense, largely from scratch. The Meiji government, aiming to assert control and promote development in what was then called Ezo, implemented a centralized, top-down administrative plan. This plan deliberately bypassed the historical county framework, which was associated with the feudal land tenure systems being dismantled elsewhere in Japan. Instead, the island was conceived as a single, vast administrative entity—the Hokkaido Prefecture—subdivided into smaller units like subprefectures (*shichō*) and, for geographic reference, the uniquely Hokkaido "road" system.

The "roads" of Hokkaido, such as the Oshima, Iburi, or Kamikawa roads, are not administrative jurisdictions in the legal sense that counties are in other prefectures. They are best understood as large-scale geographic and planning regions, originally established for infrastructure and settlement purposes. Their names often derive from major routes or geographic features, serving as a functional taxonomy for organizing the vast, sparsely populated land. This system reflects a pragmatic, development-oriented approach where the primary state goals were land survey, resource exploitation, and the establishment of transportation corridors and agricultural settlements. Consequently, the fundamental administrative units beneath the prefectural level became cities (*shi*), towns (*chō*), and villages (*son*), which report directly to the prefectural government or through branch offices, without an intermediate county layer. The road system persists as a deeply ingrained cultural and geographic identifier, used in addresses, business names, and weather reports, but it carries no governing body or legal authority.

The implications of this structure are significant for governance and regional identity. Administratively, it results in a more centralized prefectural government in Hokkaido, which must manage a vastly larger and more diverse territory than any other prefecture. This has necessitated the creation of comprehensive subprefectural branch offices (*shichō*) to deliver services, a system that functionally replaces some county-level coordination but operates as an arm of the prefecture rather than a historical community. The absence of counties also means that Hokkaido lacks the subtle layer of historical and cultural affiliation that counties provide in other regions, where they often correspond to ancient provincial boundaries. In Hokkaido, regional identity is instead closely tied to these "road" areas, which have evolved into coherent socio-geographic regions despite their non-governmental status. This unique framework underscores how modern Japan's administrative geography is not monolithic but is shaped by the specific historical contingencies of frontier integration, leaving Hokkaido with a distinctive spatial organization that prioritizes developmental logic over historical continuity.
