Yes, so if Uncle Sam allowed them to go on and build one, they could, instead, they are not so they have to go about the Soryu route. I however, am not qualified to talk about American law and policy towards Japan, but from what i do know, Japan has restrictions on it postwar, alongside the US policy of Nuclear hegemony.
But aside from this, you are yet to raise any valid point about a first generation, research reactor/sub being developed within 20-30 years, to use as a iterative stepping stone into a fully operational, combat ready SSN/BN
Your GDP is smaller than Bangladesh, you don't have the luxury of a 20-30 year "research project" you need a viable product in the 1st gen, not a research product.
This isn't "eat grass", b/c at the end of the day the bomb is still viable no matter if its not a hydrogen bomb or not a more sophisticated design. Nuclear Subs(with viable operational capacity in the modern battlefield) don't work like that.
Nuclear Submarines are very very difficult especially without input from an experienced nation, as India got with Soviet/Russia.
