This relative naming confused me for a while, since I was pretty sure that no Japanese emperor had reigned for 94 years, until some Googling revealed that 94 meant Japanese Imperial Year 2594 (i.e. 1934), on the crazy year-numbering system the Japanese were so fond of in the 1930s. I suppose this illustrates the cultural differences between 1920s Japan and 1930s Japan.
