The Former Onagawa Police Station is a disaster memorial located in Onagawa Town, Miyagi Prefecture. It is a structure that was severely damaged by the massive tsunami during the Great East Japan Earthquake on March 11, 2011. Rather than being demolished, parts of the building have been preserved in their damaged state to serve as a vital resource for understanding the power of natural disasters. Situated along the coast of Onagawa, it functions as a "living textbook" to ensure that the memories of the disaster are never forgotten by future generations.
The Great East Japan Earthquake in 2011 caused catastrophic damage across the coastal areas of the Tohoku region. The Former Onagawa Police Station was one of the buildings heavily impacted by the tsunami. As Onagawa underwent a period of intense reconstruction, the community made the profound decision to preserve this building as a "Disaster Memorial Site" rather than rebuilding it. This is not just a way to record history, but a cultural initiative to enhance disaster preparedness and community awareness for future generations.

Visitors can observe the physical traces of the tsunami on the exterior walls and interior structure, including the height and force of the water. The visible damage provides a powerful visual representation of the scale of the disaster. The preserved areas still retain the atmosphere of the spaces where daily life and official duties once took place, offering a poignant look at how the disaster transformed the community. The contrast between this weathered structure and the modern, rebuilt townscape is a striking feature of the site.
As an outdoor memorial site, the area is accessible 24 hours a day. However, it is highly recommended to visit during daylight hours to clearly observe the structural damage and the intricate details of the tsunami marks. While you can visit in any season, please be aware that the location is near the coast; during winter or inclement weather, the area can be quite windy and exposed to the elements. Visiting during the day ensures the most vivid experience of the site's historical significance.

The primary way to experience this site is through quiet observation and reflection. By examining the building's structure, visitors can engage in a form of disaster prevention learning. Walking through the surrounding coastal area also allows you to feel the transformation of the town from the pre-disaster era to the current reconstructed landscape. This quiet environment offers a profound opportunity to contemplate the power of nature and the resilience of the local community.
The Former Onagawa Police Station is located near the Onagawa coastal road. The surrounding area features a modern, vibrant townscape that symbolizes the successful reconstruction of the region, complete with various shops and restaurants. After visiting the memorial, we recommend strolling through the nearby coastal parks and the reconstructed shopping streets to gain a deeper understanding of both the past (the disaster) and the present (the recovery) of Onagawa.
