I disagree with the state control aspect of it. Let's remember that Japan had extremely high literacy rates for those times and had developed into several large urban zones with countryside not too far behind in development; thus more equal.
Also, I wouldn't say that a state who's history was defined by constant warring daimyo is particularly centralized. Further, it was late into the game, I would argue that most any nation or people could build up large infrastructure and create a healthy market if they possessed the population of Japan and its isolation and thus freedom from foreign stress.
This theory, also assumes that a state interventionist economy and government is what creates industrialism. However, there are models that also suggest the opposite, especially in earlier states, who experienced extreme economic prosperity before industrialism. Ottomans for instance had a command economy and regulated and restricted everything possible and I would argue that the Ottomans were some of the worst in terms of economics. That being said, they certainly had an industrial economy, albeit very backward and sparse.
As others will say, the Qing dynasty had a full control economy in many aspects and did build railroads and modernize areas just like Japan. Yet, it did nothing for the overall economic and political instability.
We also should look at the nations that we even have in Africa and Asia to even think about why Japan was able to have its success.
Korea: Small, isolated from everything, fairly rural, doubtful to do anything specific in this regard.
Tibet: mountains and ruled by a monastic state essentially; should I say more?
Iran: has been through several different regimes all of which except the Safavid brought military and economic woes to the nation. Completely devastated by several series of plague both in Tehran and Isfahan. At this point, Iran has hit its lowest point in its long history.
The Mughals were defeated and destroyed really before they could have a chance.
Afghanistan, is simply too small and it really hasn't modernized completely yet.
Ethiopia, I do not know too much on this one.
Basically, we In otl did not have the best selection of nations for a case study into why a state outside of Europe can modernize. We had States who heralded the most depressed states in their histories.
