12.09.2026The Day Mt. Tokachi's Alert Rose to Level 3

Overnight reports of North Korea firing short-range ballistic missiles toward the Sea of Japan opened the day, with South Korean military announcements carried by TBS and Kyodo.

Attention quickly shifted to Hokkaido, where the Meteorological Agency raised Mt. Tokachi's eruption alert from 2 to 3, imposing entry restrictions. Outlets stressed it was the first Level-3 application in Hokkaido, followed by an evacuation order for the Fukiage Onsen district in Kamifurano and warnings of large volcanic blocks within about 3 km of the crater. NHK maintained live coverage through the morning.

By afternoon editorial choices splintered. Hokkaido Shimbun turned to the LDP's selection of a candidate for the Sapporo mayoral race, Mainichi and others to the Okinawa gubernatorial vote on the eve of polling, and NHK to suspected mass food poisoning at the corporate athletics championships in Kyoto with more than 20 transported.
