This chapter empirically analyses the relationship between wrestlers’ hometown characteristics and their competitive performance. Wrestlers from impoverished rural areas possess strong incentives to succeed in sumo, as returning home after relocating to Tokyo is not easily feasible. Data analysis reveals that wrestlers from regions with lower population density and greater distance from Tokyo tend to have longer active careers and achieve higher ranks. Hokkaido-born wrestlers’ exceptional performance stemmed from two factors: economic hardship and geographical distance. Examining yokozuna origins post-WWII shows Hokkaido and overseas-born wrestlers are notably predominant. This supports economic theory suggesting that individuals from disadvantaged backgrounds possess stronger motivation for success. Conversely, Tokyo-born wrestlers have relatively lower incentives, as they can return to local life if unsuccessful. This analysis demonstrates that success mechanisms in the sumo world depend not merely on physical ability but are deeply rooted in economic and social backgrounds. The chapter provides empirical evidence for how economic incentives shape career outcomes in traditional Japanese society, offering insights applicable to broader labor market dynamics.
