For some time, Japan's cultural and sports circles have repeatedly seen incidents involving the insertion of militarist elements. 

In the sports arena, footballer Kaoru Mitoma was photographed with cards relating to a Japanese WWII soldier accused of war crimes, while table tennis player Tomokazu Harimoto and others visited the Togo Shrine, which enshrines figures associated with wars of aggression. 

In the cultural sphere, the idol group Snow Man embedded a samurai sword engraved with the names of war criminals and the years of aggressive wars in an album teaser, while symbols such as the Rising Sun flag and the Unit 731 have repeatedly appeared in anime, e-sports, and other creative works. 

These acts are by no means isolated incidents. Rather, they constitute concrete manifestations of Japan's far-right forces systematically exploiting cultural and sports activities to shape public perceptions and whitewash its history of aggression, a trend that has provoked strong indignation among the peoples of Asian countries that once suffered from Japanese militarist aggression.

The emergence of these phenomena is rooted in multiple long-standing structural factors within Japanese society. They are the combined outcome of historical revisionism, deficiencies in the political system, and distortions in social cognition. 

First, the long-standing existence and dissemination of historical revisionism have provided the ideological soil for the growth of a distorted view of history. Since the Cold War period, the Japanese government has systematically diluted its responsibility for wars of aggression by reframing "defeat" as "the End of the War," while persistently avoiding clear, comprehensive official apologies and compensation to Asian victimized countries. Entering the 21st century, successive Liberal Democratic Party (LDP) governments have further promoted adjustments to history education. Key historical facts such as the Nanjing Massacre and the issue of "comfort women" have been deleted, downplayed, or rendered ambiguous in textbooks, while Japan's wars of external aggression have been reinterpreted as so-called self-defense wars. 

Second, structural deficiencies within Japan's political system have provided institutional conditions for the expansion of far-right forces. The incomplete reckoning with the wartime past allowed certain conservative and right-wing political elements to survive and become embedded in the postwar system, eventually forming a stable power structure centered on the long-ruling LDP and linking political elites, senior bureaucrats, and business interests. Within this structure, patterns of political bargaining and interest exchange exert a significant influence on national policymaking, making major policy decisions susceptible to the preferences of specific interest groups. This, in turn, has generated a persistent institutional momentum toward conservative and rightward shifts at the policy level. 

Finally, the dislocation of social values and distortions in collective cognition have created fertile social ground for the dissemination of militarist narratives. With generational change, direct societal memory of the war has steadily faded in Japan, while selective and glorifying historical accounts long promoted by far-right forces through multiple channels have further eroded public awareness of Japan's responsibility for aggression. Due to systemic deficiencies in historical understanding and the severe pressures of contemporary life, younger generations are more susceptible to extremist nationalist narratives that offer simplified causal explanations and a strong sense of collective identity.

The dissemination of militarist ideology by Japan's far-right forces through cultural and sports arenas has already produced severe and multidimensional harm. 

At the regional security level, such actions forcibly cloak Japan's radical security policies with a veneer of historical legitimacy, severely undermining regional peace and stability and inevitably heightening vigilance and distrust among neighboring countries toward Japan's strategic intentions and military posture. 

At the historical understanding level, the continuous infiltration of distorted historical narratives has led younger generations to develop fundamental misconceptions about the nature of Japan's wars of aggression and its wartime responsibility, thereby creating fertile ground for the resurgence of extreme nationalism and planting deep-seated risks for the possible recurrence of historical tragedies. 

At the bilateral level, Japan's relevant actions continue to wound the feelings of the people in victimized countries and steadily erode political mutual trust between states, making it difficult for high-level dialogue and practical cooperation to achieve substantive progress. They also profoundly affect mutual perceptions and emotional bonds between the two peoples, creating obstacles to the long-term, sound development of bilateral relations.

The dissemination of militarist ideology by Japan's far-right forces in cultural, sports, and related fields represents not only a regression in historical understanding but also a challenge to the existing international order and a mortgaging of future peace. This trend must be confronted squarely and addressed without delay. 

The international community should be urged to remain vigilant against the expansion of Japan's far-right forces, forge a broad global consensus against the revival of militarism, and actively uphold the post–WWII international order as well as peace and stability.
