A fire started around 11 a.m. on June 19 in or near the music room on the 4th floor of Takinogawa Daisan Elementary School in Kita Ward, Tokyo [1, 2, 3]. The blaze burned approximately 150-200 square meters, affecting the music room and adjacent areas on the same floor [2, 4, 5].

About 300 to 340 students and staff evacuated safely during the incident [6, 1, 7]. Classes for 24 fifth graders were underway in the music room when the fire began [1, 3]. Students and teachers escaped down stairs or climbed out windows onto a narrow ledge, where firefighters later rescued some using ladders [6, 2, 8, 9]. Three students and one teacher became trapped and were rescued by firefighters [7, 2, 5].

Police and fire departments dispatched between 50 and 75 fire engines, with dozens of firefighters on scene battling the fire until it was mostly extinguished around 1:45 p.m. [7, 8, 5]. There are slightly differing reports on the exact number of fire engines; some say about 50-60 while others report up to 75 [1, 7, 4].

Ten to eleven people were injured in the fire, including 8 or 9 students and 2 teachers [1, 7, 2, 3]. Most injuries were due to smoke inhalation, though there were some fractures among children and teachers. Accounts differ on the number and identity of those with fractures; some report one teacher broke a hip and two children had arm fractures, while others note initially three fractures but later one child ruled out [7, 2, 3].

Witnesses described the flames and smoke spreading quickly. A sixth-grade student recalled, "We thought maybe someone was cooking... Then the siren went off. Then we saw the music room already burning with flames. It was scary, and a lot of kids were crying" [6]. Another student described the thick smoke and explosion sounds during evacuation [5].

Investigations by police and fire departments on June 20 and 21 suggest the fire was accidental. It likely originated from an electric heater in the music room, with no evidence of malfunctioning air circulators or third-party involvement [3, 10, 11].

The school and authorities continue to assess damage and support the injured. Firefighters remain on site as recovery proceeds.
