Chadwick announced the discovery of the neutron 10 May 1932 and Hahn and Strassman announce the discovery of fission on 17 November 1939.
Remember the journalist’s moto ‘never let the fact get in the way of a good story’.
Hahn and Strassman announced the discovery, that is true. But many physicists had posited the idea of nuclear fission well before it was actually documented in a laboratory experiment, as I think you know full well.
It is possible that Nishina, Heisenberg, et al were "talking about...something more exotic" than what we know today as an atomic fission bomb. This was not uncommon at the time. Mark Twain and Nicola Tesla talked about exotic weaponry, or the possibility of it, in their long correspondence, and that was in the late 19th and early 20th centuries.
But the main point here is Shimatsu's allegation that a German-Japanese consortium began mining uranium-bearing ores in Japan following Heisenberg's 1929 visit to the Riken, and also his statement that the WWII Japanese nuclear weapons projects infrastructure included Hungnam. All of which is entirely consistent with Wilcox and his book. Monazite ores often contain uranium deposits, and there is monazite on Mount Uzumine and throughout the nearby Abukuma Mountains. Surely uranium mining would point not to "something more exotic", but rather to definite interest in nuclear fission for weapons and for motive power.

PS No true journalist would put a story before the facts. A propagandist or an ideologue or demagogue would, or what they used to call a "yellow journalist". Not a true journalist.
