Thebombing of Toyohashi (豊橋空襲,Toyohashi kūshū) was astrategic bombing operation on the night of 19 June 1945 against the city ofToyohashi,Japan. The air raid was part of theAllies'air raids on Japan during thePacific War.[1]
During the Pacific War, as now, the city ofToyohashi, Aichi was an important hub in the transportation network of central Japan.Toyohashi Station is located along theTōkaidō Main Line linkingTokyo andOsaka, and also serves as the origin of theIida and Atsumi Lines which facilitate access to rural areas of easternAichi Prefecture. The city had a fairly small industrial base at the time, but it was more important for its port facilities onMikawa Bay. In addition to these strategic civilian targets, Toyohashi hosted a number of military targets, such as a large training area forImperial Japanese Army recruits located nearAichi University,[2] and the headquarters of several army units, including the18th Infantry Regiment, the 4thCavalry Brigade, and the 4th IndependentCombat Engineer Regiment. Toyohashi also had an airfield that served the 381st Naval Air Group which flewMitsubishi J2MRaideninterceptors.[3]
There were nine air raids on Toyohashi between January and June 1945. About 25-30 people were killed in the first eight. These early air raids are barely mentioned in relevant historical texts and were probably the result of Allied bombers hitting Toyohashi as an alternate target or a target of opportunity.[4] Only the ninth raid, by far the largest, became known as "The Toyohashi Air Raid". Starting late on the night of 19 June or after midnight, in the early hours of 20 June 1945, 136Boeing B-29 Superfortresses conducted afirebombing operation on the city of Toyohashi. The air raid lasted for about three hours, and ended a little before dawn. The areas primarily affected included a large part of the downtown area between Toyohashi Station and City Hall, large sections of the Azumada and Maebata neighborhoods, and neighborhoods around Azumada Elementary School.[5]
On the same night as the Toyohashi Air Raid, two otherfirebombing operations were being conducted elsewhere in Japan. One was in neighboringShizuoka prefecture, and would become known as theGreat Shizuoka Air Raid (静岡大空襲Shizuoka dai-kūshū). The other was the Great Fukuoka Air Raid (福岡大空襲Fukuoka dai-kūshū) on the island ofKyushu.

In the aftermath of the Toyohashi Air Raid, Japanese authorities compiled the following data on the damage done on the night of 19–20 June 1945:[6]
Among the buildings that were destroyed were five temples, Azumada Elementary School,[7] and the Kawai Hospital (which was rebuilt, though it has changed ownership and location several times, and is now the Oshima Orthopedic Clinic in the Ihara neighborhood).[8] In 1946, theUnited States Army Air Forces estimated that 61.9% of the city had been destroyed.[9][10]
While property damage in Toyohashi was high, casualties were relatively light. This was due in part to lessons learned from the several air raids on neighboringHamamatsu city, which had suffered much more since its first air raid in February 1945.[11]
