The Power Hitter Pantheon: Baseball’s Greatest Home Run Heroes
This project aims to determine the greatest home run hitter of all time by comparing each slugger’s statistics to the average of their era using three formulas. The final adjusted stats will then be used to compare them head-to-head with other all-time greats.

Noboru Aota will be the next legendary Japanese League home run hitter examined in this study. For a brief overview of Aota's biography, please click here.
According to Baseball Reference, Aota's official statistics reveal a total of 265 home runs over 6,566 at-bats, resulting in an average of 24.78 at-bats per home run (AB/HR).
Aota played in the Japanese Baseball League (JBPL) from 1942 to 1949, followed by the Central League (JPCL) from 1950 to 1958, and the Pacific League (JPPL) in 1959. When aggregating the statistics from all these leagues, the combined total includes 461,836 at-bats and 6,758 home runs, resulting in an average of 68.34 at-bats per home run (AB/HR) across the leagues in which Aota played.
With this data, we can evaluate how Aota’s performance compared to the average Japanese League hitter of his era.

Aota was a powerhouse. His 24.78 AB/HR compared to the 68.34 league average paints him as a standout slugger. The raw difference of 43.56 at-bats per home run highlights how much more often he went yard compared to his peers.
The improvement factor of 2.76 is particularly striking—it suggests he was clearing the fences at nearly triple the rate of the typical hitter in those leagues during his era. The 63.74% percentage difference further quantifies his dominance, showing his power output was leagues ahead—literally.
In our initial analysis, we examined the careers of Mickey Mantle, Alex Rodriguez, and Joe DiMaggio using our formulas. Following that, we also evaluated the careers of Josh Gibson, Sadaharu Oh, Buck Leonard, Tetsuharu Kawakami, and Mule Suttles.
Now, let's compare Aota's career statistics against these baseball legends to gain a clearer perspective on how he stacks up.
Against MLB legends, Aota proves himself to be a formidable slugger. His performance is nearly on par with Mickey Mantle (63.74% vs. 63.32%) and Joe DiMaggio (65.85%), indicating that his power was comparable to these Hall of Famers within the context of their respective eras/leagues.
Aota’s relative power surpasses that of Alex Rodriguez (63.74% vs. 51.59%). These statistics suggest that Aota was a dominant slugger who significantly outperformed the average hitter of his time.
