The Asahi News recently reported the following:
Hideo Kinoshita as the superior of the two journalists recorded the branch's set up by contributing an article to the December 71st year edition of the Bungeishunju, noting that "everything was done in the deepest secrecy", and that was the recollection. "As for President Truman's atomic bombing statement, Potsdam Declaration, and the confirmation that Japan had reached the surrender acceptance with other parties, all the first reporting were captured here".
Immediately after the message was transmitted to Foreign Minister Togo in the afternoon of 7th August, the Imperial HQs announced that the nuclear weapon dropped at Hiroshima was a "New Bomb". It was on the 14th that the army acknowledged the "Atomic bomb" and made public the danger of residual radioactivity in the bombed area.
Professor emeritus (history of science) Masakatsu Yamazaki of Tokyo Institute of Technology who knew in details the history of the nuclear development thought that without making the best use of information from the news agency was one reason for the large amount of secondary radiation exposure. "During the war in Japan specialists who were researching on the military application of uranium knew the danger of residual radioactivity, but neither the army nor the government were told and they entered Hiroshima and Nagasaki immediately after the atomic bombing, and a lot of people lost their life".
Torii had planned on publishing a series concerning the Kawagoe branch in "Media Prospect", the bulletin of the Newspaper Communication Investigation Committee.
The event happened in the Kawagoe branch is quite an interesting historical finding in Japan about WWII.
