As sea levels stabilized and no larger waves were observed, authorities downgraded tsunami warnings to advisories, indicating the potential for waves of up to one meter in parts of Hokkaido, Aomori, Iwate, and Fukushima prefectures. All tsunami advisories were lifted around midnight, according to domestic media reports, and normal marine and port operations were progressively restored. Footage from national broadcaster NHK from several ports in Iwate showed no clearly visible extensive damage to port infrastructure, though inspections of coastal facilities, vessels, and cargo areas were still ongoing, and insurers were expected to rely on on-the-ground surveys to validate early impressions.
