Abstract This study investigates how five successive great fires between 1878 and 1934 fundamentally reshaped Hakodate’s urban landscape, transforming a vulnerable, timber-built frontier port into a resilient, fire-resistant modern city. Contrary to prevailing views that modernisation derived chiefly from the 1854 opening under the Treaty of Kanagawa, our findings demonstrate that late nineteenth- and early twentieth-century conflagrations were the decisive catalysts for enduring spatial change. Employing a multidisciplinary approach?combining primary archival sources, GIS-integrated historical maps, and quantitative metrics such as street-width expansions and masonry construction rates?we analyse the fires of 1878, 1879, 1907, 1921, and 1934. Initial vulnerabilities lay in dense wooden machiya housing, narrow 2?3 m alleys, and peninsula wind patterns that accelerated fire spread. In response, municipal authorities implemented four sequential reconstruction phases: (1) widening key thoroughfares from 3?4 m to 6?8 m and establishing an orthogonal grid network as firebreak roads; (2) mandating masonry, brick, and reinforced-concrete cladding for all new and rebuilt structures; (3) creating a network of 30×30 m plazas at 200 m intervals linked by pressurized hydrant mains, serving as parks in peacetime and evacuation/firebreak nodes in emergencies; and (4) after the catastrophic 1934 blaze, establishing a citywide greenbelt of 33?55 m-wide linear parks hosting fire stations and enforcing updated building codes requiring fire-rated doors and noncombustible exteriors. Comparative analysis with contemporaneous recovery models in Edo (Tokyo), Yokohama, and Osaka reveals that Hakodate’s locally driven, heritage-sensitive, and comprehensively integrated fire-prevention infrastructure stands in sharp contrast to centrally dictated or foreign-led plans. We propose the concept of “disaster-triggered modernization” as a guiding framework for coastal port cities seeking to balance cultural-landscape preservation with infrastructure resilience under escalating climate threats. By tracing the iterative cycle of disaster, institutional reform, and urban-planning innovation, this study offers actionable insights for planners in disaster-prone regions aiming to achieve sustainable, heritage-respectful, and disaster-resilient urban development.
