Introduction

The slang terms "oyakodon" and "three-generation donburi," popularized on platforms like X and across the internet, have become symbolic of criticisms leveled against Sohei Kamiya, leader of the Sanseito Party, concerning his alleged personal relationships and ethical conduct. These terms suggest inappropriate relationships with women across different generations, though concrete evidence remains scarce. This article examines these allegations and related ethical issues surrounding the Sanseito Party, drawing on credible reports, X posts, and official party statements, while clearly distinguishing between verified facts and speculation.

Background of "Oyakodon" and "Three-Generation Donburi"

"Oyakodon," a traditional Japanese dish combining chicken and egg over rice, has been co-opted in certain online circles as a slang term implying unethical relationships between a man and both a mother and her daughter. Similarly, "three-generation donburi" extends this metaphor to include a grandmother, mother, and daughter. These terms, circulated on X, lack substantiated evidence and often appear as provocative gossip rather than verifiable claims.

• "Kamiya's 'oyakodon' refers to extramarital affairs. Sanseito's ethics are questionable." (Anonymous X user)
• "There’s even talk of a 'three-generation donburi.' Kamiya allegedly has wide-ranging relationships." (Former party member, X post)

These claims highlight perceived contradictions with Sanseito’s advocacy for traditional family values, but no mainstream media has corroborated them. The allegations may be exaggerated or driven by critical intent online. For further details, see Sanseito Ethics Analysis.

Allegations of Personal Relationships Involving Sohei Kamiya

Allegations concerning Kamiya’s personal relationships can be categorized as follows, with verified and unverified information clearly delineated.

1. Extramarital Affairs and Relationship Allegations

Claims of inappropriate relationships with multiple women have surfaced, though evidence is limited:

• "Mistress OK" Statement: Kamiya reportedly stated in a public speech that "Sanseito is fine with mistresses," raising concerns about his stance on extramarital affairs. A former party member claimed Kamiya does not view infidelity negatively, as cited in a Shukan Shincho article (July 9, 2025), though no audio or video evidence clarifies the context.

• "Kamiya Girls": Female Sanseito members and staff are allegedly referred to as "Kamiya Girls," implying close relationships, but no evidence confirms impropriety. Related Post

2. Former Secretary’s Suicide

In December 2023, a female public secretary (referred to as Ms. A) under Kamiya’s employ died by suicide, sparking allegations of power harassment:

• According to Shukan Bunshun, Ms. A faced severe reprimands from Kamiya for insufficient event attendance, contributing to a toxic work environment that may have led to her death. Shukan Bunshun Report
• Kamiya has denied power harassment, but multiple sources confirm his stringent management style. No direct link to the "oyakodon" allegations has been reported.

3. Inappropriate Statements and Behavior

Kamiya’s public statements and actions have drawn criticism:

• 2025 Election Remarks: Kamiya’s comment that "only young women can bear children" during the 2025 election campaign was criticized as sexist. The statement, reportedly edited in Sanseito’s YouTube videos, lacks evidence of deliberate concealment. Mainichi Shimbun Article
• "Embraced Woman" Post: A Sanseito Shimane account posted about Kamiya hugging a young girl, calling her "the woman embraced by Sohei Kamiya," which was deemed inappropriate and later deleted. Related Article
• Conservative Gender Views: Kamiya’s opposition to selective surnames for married couples and same-sex marriage reflects traditional gender norms, criticized as dismissive of women’s rights but not directly tied to personal relationship allegations. Asahi Shimbun Article

Sanseito’s Operations and Ethical Challenges

Kamiya’s actions have broader implications for Sanseito’s operations and ethical standing:

• Opaque Political Funding: A 2022 financial report revealed expenditures of approximately ¥133 million to SBC Co., Ltd. (headed by Kamiya’s wife), ¥18 million to Kamiya’s personal company, and ¥19 million to Kamiya himself, raising concerns about potential misuse. Shukan Bunshun Report
• Conspiracy Rhetoric: Kamiya’s references to "deep state" conspiracies are seen by some as deflecting criticism, potentially obscuring ethical issues. Mainichi Shimbun Article

Factual Summary

The following summarizes verified facts and unverified allegations:

• The "mistress OK" statement and "Kamiya Girls" moniker are discussed on X and in some reports but lack concrete evidence of infidelity.
• The 2023 suicide of a former secretary, reported by Shukan Bunshun, suggests potential power harassment within Sanseito’s work environment.
• Inappropriate statements ("only young women can bear children," "embraced woman") are documented and criticized as sexist or unethical.
• Political funding irregularities, as reported by Shukan Bunshun, undermine Sanseito’s operational transparency.

Contradictions with Sanseito’s Ideology

Sanseito’s advocacy for "Japan-first" policies and traditional family values is at odds with Kamiya’s alleged behavior and statements. These issues, widely discussed among supporters (over 400,000 YouTube subscribers), erode the party’s credibility. Mainichi Shimbun Article

Conclusion

The allegations of "oyakodon" and "three-generation donburi" surrounding Sohei Kamiya, while widely circulated on X, remain largely unsubstantiated, resembling digital folklore more than fact. However, credible reports from outlets like Shukan Bunshun and Mainichi Shimbun confirm issues of power harassment, inappropriate statements, and questionable financial practices, which cast a shadow over Sanseito’s ethical foundation. These discrepancies between the party’s proclaimed values and its leader’s actions warrant further scrutiny. Readers are encouraged to approach this topic with critical discernment, relying on verified information to navigate the complex interplay of rumor and reality.

Metaphorical Use of "Oyakodon"

In recent years, "oyakodon" has acquired a metaphorical connotation in informal contexts, referring to unethical relationships involving a mother and daughter with the same individual. This usage, prevalent in subcultures and online platforms, is considered inappropriate in formal settings due to its potential to offend.

Emergence of "Three-Generation Donburi"

An extension of the "oyakodon" metaphor, "three-generation donburi" implies relationships spanning a grandmother, mother, and daughter. While sometimes used humorously, this term carries significant risk of being perceived as crass or offensive in public discourse.

Guidelines for Public Entities

The terms "oyakodon" and "three-generation donburi" carry a visceral, almost tactile quality, evoking complex familial and emotional dynamics that can border on the taboo. Their usage risks breaching decorum in public settings, as they transcend mere words to evoke provocative imagery. Public figures and institutions must exercise restraint, recognizing the terms’ potential to undermine dignity and incite controversy. Language, in its raw potency, can resonate deeply, and such terms demand careful handling to maintain ethical discourse.
