Aomori, Miyagi, Hokkaido: Earthquake Risks in Japan – What Tourists Need to Know to Stay Safe: Earthquake Impact on Japan’s Pacific Coast – How to Navigate Travel Disruptions

Published on December 12, 2025

Japan’s Pacific coast has experienced a new earthquake with a 6.9-magnitude tremor, hitting a similar area to Monday night’s 7.5-magnitude quake. The fresh tremor, off Aomori Prefecture, triggered a tsunami advisory for the coastal areas of Hokkaido, Aomori, Iwate, and Miyagi prefectures, with authorities warning of possible 1-meter tsunami waves. Fortunately, the advisory was lifted around two hours later, but not before coastal communities in these areas were evacuated for safety.

While the exact details of any damage or injuries from the December 10 quake were not immediately clear, the event adds to the ongoing seismic activity in the region. The Japan Meteorological Agency (JMA) issued the warning after the earthquake, but the situation seemed to stabilize as the tsunami risk diminished.

This earthquake follows Monday’s 7.5-magnitude quake, which caused injuries to at least 51 people and triggered tsunami warnings. With aftershocks predicted and the megaquake advisory still in place, residents of the affected regions are on edge, preparing for the worst.

Aftershocks and Megaquake Advisory: Ongoing Risks in Aomori and Hokkaido

Following the earthquake on Monday, there has been significant concern over the possibility of aftershocks. Japan’s weather agency issued the highest-level warning—the megaquake advisory—which remains in place until December 16. This alert, the first of its kind since the launch of the warning system in 2022, signals the potential for an earthquake of magnitude 8 or higher, a phenomenon that would be devastating for the region.

The megaquake advisory has left many residents in Aomori and Hokkaido preparing for an uncertain future. As a result, stores in these areas are experiencing increased sales of emergency supplies such as water, portable toilets, stabilizers, and adjustable poles to secure household furniture. This heightened preparedness reflects the anxiety many feel as they wait for the potential of further seismic activity.

Impacts on Tourism and Business Travel in Japan

The impact on tourism and business travel is already evident, especially as local infrastructure and transport networks have been affected by the ongoing seismic risks. For tourists planning to visit Japan, particularly those heading to Hokkaido, Aomori, or Miyagi, it is essential to stay informed of the latest travel advisories. Many tourist sites in Japan have temporarily closed or limited access to ensure the safety of visitors.

For business travellers scheduled to attend events, conferences, or meetings in Japan, particularly those in Sapporo, Sendai, and Aomori, it’s important to account for potential delays or cancellations in transportation, as well as disruptions to planned activities. Companies are advised to review their travel protocols and ensure contingency plans are in place in case of further seismic activity.

Scope of Earthquake Activity and Regional Concerns

With the ongoing megaquake advisory, Japan is on high alert for further seismic activity. The Pacific coast, particularly Hokkaido, Aomori, and Miyagi, remains a high-risk area for earthquakes and tsunamis, as seismic events continue to disrupt daily life.

In addition to natural disasters, there are concerns over the economic impact on local businesses, especially in tourism-dependent regions. The travel and hospitality industries have been particularly affected, with many tourists canceling their trips or adjusting their plans due to the instability caused by the recent quakes. For international tourists, this may mean revised itineraries and adjusted travel routes to avoid the affected regions.

Conclusion: Preparing for Earthquake Risks in Japan

While Japan remains a popular destination for tourists and business travellers, it’s important to stay vigilant, especially during periods of heightened seismic activity. The recent earthquakes and the megaquake advisory serve as a reminder of the importance of preparedness when visiting seismic zones.

For travellers to Hokkaido, Aomori, or Miyagi, checking the latest updates on earthquake risks, evacuation routes, and transportation options is essential to ensuring a safe and smooth journey. While the risks are high, Japan’s commitment to resilience and safety measures makes it possible to continue enjoying the beauty and culture of the country, even in the face of unpredictable natural events.
