Apr 24, 2026, 10:41

Introduction

Two wildfires in northern Japan''s Iwate Prefecture continued to spread toward the town of Otsuchi on Friday, leading authorities to issue evacuation orders for thousands of residents and mobilize firefighting resources. The blazes, which started on Wednesday, remain uncontained.

Main Body

The first fire started on Wednesday afternoon in a mountainous area of Iwate Prefecture. Approximately two hours later, a second fire began about 10 kilometers away near Otsuchi town, according to media reports. As of Friday morning, government spokesman Minoru Kihara stated that the fires had burned over 400 hectares since they started. Later reports from public broadcaster NHK indicated that the total area burned had exceeded 1,176 hectares. This makes it the second-largest wildfire in Japan, behind the 2025 Ofunato fire, which burned about 3,370 hectares, as reported by TBS News. Evacuation measures expanded over the course of Friday. Initial advisories covered more than 2,500 people, with 329 residents taking shelter as of 5:00 a.m., according to NHK. Later, NHK reported that evacuation orders had been extended to 1,541 households, including 3,233 individuals. As a result, one evacuation shelter was closed on Friday morning as the fire approached. Seven buildings, including one residence, have been destroyed. No deaths or injuries have been reported. Firefighting efforts involved approximately 700 personnel and 13 aircraft, as stated by Kihara. The Fire Department has been fighting the flames from both ground and air, but the fires remain uncontained. A local firefighter described the sound of cedar trees cracking and burning as flames and smoke rose, according to broadcaster TV Asahi. Furthermore, increasingly dry winters have been cited as a factor that increases wildfire risk. The 2025 Ofunato fire was Japan''s worst in over half a century.

Conclusion

The wildfires in Iwate Prefecture continue to spread toward residential areas, with evacuation orders in effect for over 3,000 people. No casualties have been reported, and authorities are maintaining firefighting operations as the blazes remain uncontained.
