Emperor Taisho, son of Meiji and father of Hirohito, reigned for just under fifteen years and saw Japan endure World War I and the rise of proto-fascism. He was also thought to be intellectually delayed due either to an early infection or lead exposure. Supposing he excels in intelligence instead of lags (at least an average of Meiji and Hirohito) and still married Kudo Sakato, what does his reign look like and how much longer would he live without these exposures? What consequences does this Francophonic Emperor have on World War II, if any?
