He's the leading figure in Japanese nuclear research, spear-heading the Ministry of Research and Development's
Nuclear Energy Program. Nobody in this world is really looking into weaponizing the atom, but they're definitely on their way to developing fascinating nuclear technologies-- Conservative estimates within the Japanese government say they'll have a nuclear reactor running within 18 months-- and there's expectations that they'll be able to slowly pair down fossil fuel energy generation from there.
Other nations are involved in the nuclear energy game as well, but the only nations making progress on it are the United Kingdom, Japan and Germany. The US has been very lackadaisical about the whole thing, and the rest of the world either doesn't have the budgets, or is too busy burning to care.
He's currently heading Japanese jet propulsion technology developments at Nakajima Aircraft Company. He's responsible for the innovations internally that have lead to large fleets of jet fighters beating back the Russians and Indians from the front-lines. His work has spread to other Japanese zaibatsu to boot.
However, he's also working on side projects, particularly, rockets that can leave the Earth's atmosphere-- something that to this point hasn't been done yet.
