Japan Issues Tsunami Advisory After June 8 Earthquake
A magnitude 7.8 earthquake struck off the coast of Mindanao in the Philippines on 8 June 2026, prompting Japan’s Meteorological Agency to issue tsunami advisories covering its Pacific coastlines. Coastal travel in Okinawa and across southern Kyushu — including Miyazaki and Kagoshima — was temporarily disrupted as authorities monitored incoming wave data.
At the height of the advisory, ferry services connecting the Okinawa island chain were suspended. Diving operators, coastal sightseeing cruises, and beach resorts from the Okinawa archipelago to Kochi and Miyazaki halted operations as a precaution. Kagoshima faced compounded disruption, having already experienced flight cancellations the previous day following a major Sakurajima volcanic eruption that sent ash 3,500 metres over the city.
As of 9 June
Japan’s Meteorological Agency downgraded or lifted most advisories after monitoring confirmed no significant surge. Airports at Naha (Okinawa), Miyazaki, and Kagoshima have resumed standard operations. Ferry operators across the Okinawa island chain are restoring normal schedules through the day, though some smaller inter-island routes may reinstate services on a rolling basis as final clearance is issued.
Visitors with imminent travel to coastal or island destinations in southern Japan should contact ferry operators and tour providers directly to confirm reinstatement of services. Accommodation providers in Miyazaki and the Okinawan islands have been advised to offer flexible check-in for guests delayed by the disruption.
What to expect going forward
Japan’s tsunami warning infrastructure is among the most advanced in the world. Advisories are issued as a precautionary measure whenever seismic data indicates the possibility of a surge, and the swift downgrade on 9 June is consistent with the system working as intended. No significant wave damage was recorded along the Pacific coast.
For travellers planning multi-island itineraries that rely on ferry connections between the Ryukyu Islands, we recommend building a half-day buffer into the schedule during active seismic periods. Our Japan travel tips guide covers what to do if a natural disaster warning is in force during your visit, including how to access emergency notifications in English and Japanese. For a dedicated breakdown of earthquakes, tsunamis, and volcanic activity — including the alert level system and which apps to download — see our natural disaster safety guide for Japan.
We also recommend reviewing travel insurance ahead of any trip to Japan’s Pacific coast.
