Q:

What relief efforts did the Japanese attempt after the atomic bombings?

Obviously, once the atomic bombs dropped in 1945, the war was almost over.  There wasn't much time to rebuild, or even offer aid, to the cities of Hiroshima and Nagasaki before the Japanese surrendered and the Americans started arriving, which no doubt changed how things like war damage and reconstruction were handled.
But within that period before the end of the war, what did the Japanese government do in response to the bombings?  The Wikipedia entry contains a lot of information about the bombings, but barely any about the subsequent relief efforts or response.  Was there much of a relief effort for the survivors, or were there no resources to spare?  Did the try to rebuild anything, or did they basically just abandon the sites and focus on other areas?  Did they respond quickly, or did it take them some time to decide what to do?
And once the Americans did start arriving in Japan, did these efforts change, or did they continue largely unaffected by the surrender?

A:

In this first paragraph I will discuss what occurred at Hiroshima, in the second paragraph I will discuss what occurred at Nagasaki.
At Hiroshima, relief efforts began immediately after the bombing in an unorganized manner, but by the next day they had become organized. A joint public-private meeting was held at 10 AM, the day after the bombing where it was decided that the military should take control of all relief efforts. The leader of the Agasaki Corps who had already begun relief efforts was put in command of the Hiroshima Security Regiment Headquarters. Medical and civil defense teams were flowing into the city to help with the relief efforts. They would arrive in the city at the East Police Station and were assigned to one of the four relief areas that were determined by cardinal direction. They received many donations of food, such as rice, and other needed items, such as sandals. After the surrender, the city government took control of the military's stores distributing them to victims. According to the Hiroshima Peace Memorial Museum, this included:

(1) Rice : about 916 bags
(2) Salt : 83 bags
(3) Soy Sauce : 33701 liters
(4) Hardtack : 3300 pieces
(5) Wheat : 4 bags
(6) Canned Goods : 9214 boxes
(7) Cooking oil : 262 kg
(8) Vegetables : 10173 kg
(9) Firewood : 24260 bundles
(10) Pickled Plums : 28653 kg
(11) Miso : 11756 kg

Prefectural civil defense forces supervised by the police handled the moving of the injured, clearing of the rubble, distribution of supplies, and the disposal of the dead. These civil defense forces came from throughout the prefecture.

After being recovered the injured were transported throughout the prefecture.
