With the establishment of the modern municipalities system under the Meiji government in 1879, Toyohashi Town was created within Atsumi District, Aichi Prefecture. Toyohashi Zoo was established in 1899. The town achieved city status in 1906. A tram system (the present-day Toyohashi Railway Asumadai Main Line) was established in 1925. In 1932, Toyohashi expanded its borders by annexing Shimoji Town (Hoi District), Takashi Village, Muroyoshida Village (Atsumi District), and Shimokawa Village (Yana District). Toyohashi suffered considerable damage during the 1944 Tōnankai earthquake, and even more damage during the Toyohashi Air Raid, which destroyed more than 60% of the city in June 1945.
