Japan earthquake recovery: Lessons from 15 years of reconstruction

Fifteen years after the Great East Japan Earthquake, Yoshikatsu Okamoto, former administrative vice-minister of the Reconstruction Agency, reflects on the challenges and lessons learned during the recovery process. While infrastructure such as roads, housing, and embankments was largely restored within a decade, significant difficulties remain regarding industrial revitalization and urban planning in regions facing population decline.

Okamoto highlights three primary difficulties encountered during the recovery: the unprecedented scale of the disaster which required direct national government intervention, the necessity of relocating entire communities to higher ground to prevent future tsunami damage, and the struggle to rebuild towns in areas experiencing aging populations and youth out-migration.

He notes that while some areas, such as Onagawa, successfully consolidated housing into town centers, others, like Rikuzentakata, faced difficulties in adjusting large-scale spatial plans once they were implemented. The experience underscores the complexity of balancing immediate reconstruction with long-term demographic shifts.
