Events on the ground.
Although the bomb was more powerful than the one used on Hiroshima, the effect was confined by hillsides to the narrow Urakami Valley.
Of 7,500 Japanese employees who worked inside the Mitsubishi Munitions plant, including mobilized students and regular workers, 6,200 were killed.
Some 17,000–22,000 others who worked in other war plants and factories in the city died as well.
Casualty estimates for immediate deaths range from 40,000 to 75,000.
Total deaths by the end of 1945 may have reached 80,000.
Unlike Hiroshima's military death toll, only 150 soldiers were killed instantly, including thirty-six from the IJA 134th AAA Regiment of the 4th AAA Division.
At least eight known POWs died from the bombing and as many as 13 may have died, including a British citizen, Royal Air Force Corporal Ronald Shaw, and seven Dutch POWs.
One American POW, Joe Kieyoomia, was in Nagasaki at the time of the bombing but survived, reportedly having been shielded from the effects of the bomb by the concrete walls of his cell.
There were 24 Australian POWs in Nagasaki, all of whom survived.
The radius of total destruction was about , followed by fires across the northern portion of the city to south of the bomb.
About 58% of the Mitsubishi Arms Plant was damaged, and about 78% of the Mitsubishi Steel Works.
The Mitsubishi Electric Works only suffered 10% structural damage as it was on the border of the main destruction zone.
The Mitsubishi-Urakami Ordnance Works, the factory that manufactured the type 91 torpedoes released in the attack on Pearl Harbor, was destroyed in the blast.
Nagasaki University was established in 1949 by incorporating several national institutions, namely, Nagasaki Medical College (including College Hospital and College of Pharmaceutical Sciences), Nagasaki College of Economics, Nagasaki Normal School, Nagasaki Youth Normal School and Nagasaki High School.
The new main campus (Bunkyo Campus) was formerly a plant site of Mitsubishi Arms Factory (Ohashi Plant). 
Mitsubishi Motors Australia is a fully owned subsidiary of parent company Mitsubishi Motors Corporation of Japan.
Its Australian administrative headquarters are located at Tonsley Park (Clovelly Park, South Australia), with branch offices in Brisbane, Sydney, Melbourne and Perth.
The Tonsley Park site was the location of MMAL's vehicle assembly plant, closed in March 2008 when lacklustre sales of the large Mitsubishi 380 confirmed that domestic vehicle manufacture was no longer viable. 
Mitsubishi Motors has a long-standing presence in Thailand.
Mitsubishi Motors (Thailand) (MMTh) is headquartered in Pathumthani, just north of Bangkok.
Their flagship product is the Mitsubishi Triton (L200 in many markets) pickup truck, which is built exclusively in Laem Chabang and is exported to more than 140 global markets.
The sixth generation of the Mitsubishi Mirage is also produced exclusively at the Laem Chabang plant.
Mitsubishi had originally made Thailand their global hub for pickup production in 1995, after having become Thailand's first vehicle exporter in 1988.
This focus on global exports was of considerable aid to MMTh the tight years after the Asian financial crisis, when the local markets collapsed. 
The Mitsubishi Attrage, also known as the Mitsubishi Mirage G4, is a front-wheel drive subcompact car from Mitsubishi Motors.
It is manufactured at Mitsubishi's Laem Chabang plant in Thailand, with the possibility of a U.S. release by 2015.
The car was first introduced as a concept car at the 2013 Bangkok Auto Show called the Concept G4 sedan.
The production model is essentially a sedan variant of the current generation Mitsubishi Mirage.
According to Masaaki Yamada, senior adviser for Mitsubishi Motors Philippines, the car will use the Mirage G4 name in the Philippine market, as the Attrage has a negative connotation in the Filipino language.
The Mirage G4 was released in Philippine dealerships on October 2013.
