Tropical Storm Toraji (] ) was a short-lived and minimal tropical cyclone that brought inundating rainfall to areas of Southeast Asia in July 2007.
 The name "Toraji" was contributed to the western Pacific typhoon naming list by North Korea and stands for a broad bell flower ("Playtycodon gradniflorus").
 The third named storm of the annual typhoon season, Toraji developed from an area of disturbed weather within the South China Sea on July 4.
 As a result of its northwesterly track, the tropical depression moved over Hainan shortly after tropical cyclogenesis.
 Upon its emergence into the Gulf of Tonkin on July 5, Toraji quickly intensified into a tropical storm with winds of 65 km/h (40 mph); this would be the tropical cyclone's peak intensity for its entire duration.
 However, the JMA indicated that tropical storm intensity had been reached a day earlier.
 On the evening of July 5, Toraji made its final landfall on Dongxing, Guangxi before rapidly deteriorating inland and degenerating into a remnant low-pressure area by the following day.
