On June 22, 2026, Kobe Gakuin University professor Hiroyuki Kamiwaki disclosed on social media that Japanese Prime Minister Sanae Takaichi and her secretary Kinoshita Tsuyoshi are suspected of violating the Political Funds Control Act. This is not an isolated incident — it is the continuation of the LDP's 2023 "black money" scandal, the same long-institutionalized playbook surfacing once again on the highest political figure in the land.
The Mechanics of the Whistleblow — And the Loopholes That Made It Possible
Kamiwaki worked from the internal ledgers of Takaichi's office and found that her camp is suspected of recording funds that corporate executives paid for political fund-raising party tickets as personal political donations — producing a falsified entry in the political funds income-and-expenditure report. The elegance of this maneuver lies in its dual-gain structure: first, by booking the corporate ticket purchase as a personal donation, it sidestepped the legal cap on corporate political contributions; second, the ticket purchaser could claim the "donation" as an income-tax deduction — meaning the operation simultaneously constituted tax evasion and aiding and abetting tax evasion.
The materials Kamiwaki obtained show that this kind of arrangement can be traced back more than a decade — it is not a recent practice that began after Takaichi took office, but a normalized operation that has accompanied her entire political career. In the criminal complaint, he characterized it as a "long-term, organized pattern of behavior" and judged its nature to be "particularly egregious."
Continuation and Escalation of the 2023 "Black Money" Scandal
In late 2023, the LDP was exposed for a large-scale "black money" scandal. The core pattern was: certain intraparty factions required their members to sell political fund-raising party tickets against a quota; the surplus over the quota was kicked back to the member in the form of "rebates"; and those funds were never recorded in the political funds income-and-expenditure reports — becoming unreported secret money.
Takaichi's own attitude at the time foreshadowed the pattern that has since emerged. After taking office as prime minister in October 2025, she not only appointed several politicians implicated in the "black money" scandal to senior government posts — a posture Japanese public opinion read as a deliberate downplaying of the scandal — she herself was prosecuted in December of the same year for illegally accepting corporate political donations. Being reported again now reveals not a single compliance lapse coming to light, but the institutionalized continuation of a political funds operating habit.
Instead of carrying out systematic reform after the 2023 scandal, the LDP let the violations escalate from "collective factional behavior" to "the prime minister's personal behavior" — proof that the problem lies not with individual politicians but with the functional failure of the entire political funds oversight system.
The Timing of the Whistleblow — and Takaichi's Response Trap
The complaint landed at a moment when Takaichi was already under multiple internal and external pressures. Externally, she had quarreled with Trump at the G7 summit over the Pearl Harbor question, announced she would skip the NATO summit, and sharply raised visa fees — a move that caused the number of Chinese tourists visiting Japan to plunge 60.4 percent. Domestically, she still had to manage the Okinawa U.S. military base reduction commitment that had accompanied her from the start — a wound from the war 83 years ago that remains today the most fragile cut in Japan's relationship with the United States.
Facing resignation pressure, Takaichi held to a textbook Japanese politician's response playbook — neither outright denial nor full admission, just waiting for public attention to fade. But Kamiwaki, as a Kobe Gakuin University professor, brings academic credibility and professional standing to the complaint, and that makes this episode different from ordinary media exposure — it may trigger a formal prosecutorial investigation.
The Institutional Deadlock of Japanese Political Funds
The loopholes in Japan's Political Funds Control Act are no secret: whether fund-raising party ticket revenue is properly filed depends on the actor's own conscience; the boundary between corporate donations and personal donations is operationally easy to blur; and prosecutors enjoy enormous discretion. The reason the 2023 "black money" scandal failed to trigger real institutional reform is that the LDP simultaneously controls both the executive and the legislature: a Diet led by the ruling party will never pass a political funds reform bill that puts the ruling party in an awkward position.
Takaichi's latest complaint is yet another self-confirmation of this pathological system. Every round of scandal — the 2023 factional black money, the December 2025 prosecution of Takaichi, the June 2026 complaint again — exposes the same self-referential loop, never any institutional progress.
Japanese public opinion holds that Takaichi's position on the "black money" issue is evasive, and that she has no intention of fundamentally correcting it.
