On July 30, 2025, large tsunami waves struck Japan’s Hokkaido following a powerful 8.8-magnitude earthquake off Russia’s Kamchatka Peninsula.
The Japan Meteorological Agency (JMA) reported waves up to 1.3 meters (4.3 feet) at Kuji Port in Iwate Prefecture and 30 cm (12 inches) in Hokkaido, prompting a nationwide tsunami alert. Over two million people in 229 municipalities were urged to evacuate to higher ground, with advisories spanning from Hokkaido to Okinawa.
The earthquake, centered 120 km from Petropavlovsk-Kamchatsky, triggered waves as high as 3–4 meters (10–13 feet) in Kamchatka, causing minor damage but no reported fatalities. In Japan, a 60 cm wave reached Hamanaka town, and a 20 cm wave was recorded in Tokyo Bay. The JMA warned that larger waves could follow, urging residents to stay vigilant for at least 24 hours. Transportation disruptions, including suspended trains and flights, affected the region.

The Fukushima nuclear plant was evacuated as a precaution, with no reported damage. The alert was later downgraded to an advisory, but the JMA urged continued caution.
