Typhoon Bolaven, known in the Philippines as Typhoon Julian, was regarded as the most powerful storm to strike the Korean Peninsula in nearly a decade, with wind gusts measured up to 186 km/h (116 mph). Forming as a tropical depression on August 19, 2012, to the southwest of the Mariana Islands, Bolaven steadily intensified as it slowly moved west-northwestward in a region favoring tropical development. The system was soon upgraded to a tropical storm less than a day after formation and further to a typhoon by August 21. Strengthening became more gradual thereafter as Bolaven grew in size. On August 24, the system attained its peak intensity, with winds of 185 km/h (115 mph) and a barometric pressure of 910 mbar (hPa; 26.87 inHg).

Steady weakening continued as Bolaven approached the Korean Peninsula and it eventually made landfall in North Korea late on August 28 before transitioning into an extratropical cyclone. The remnants rapidly tracked northeastward over the Russian Far East before turning eastward and were last noted on September 1 crossing the International Dateline. Although Bolaven struck the Ryukyu Islands as a powerful typhoon, damage was less than expected. Relatively few buildings were damaged or destroyed across the region. The most significant effects stemmed from heavy rains, amounting to 551.5 mm (21.71 in), that caused flash flooding and landslides. One person drowned on Amami Ōshima after being swept away by a swollen river. In mainland Japan, two people drowned after being swept away by rough seas. In South Korea, 19 people were killed by the storm. Many buildings were damaged and approximately 1.9 million homes were left without power. Losses in the country reached ₩420 billion (US$374.3 million), the majority...
