249 companies each donated over 100 million yen to Japan’s Liberal Democratic Party over 46 years

Megabank MUFG donated the most, at 7.3 billion yen. Keidanren, Japan’s business federation, often encouraged donations to the LDP and said it was keeping a close watch on policy.
Japan’s major corporations continue to treat their non-regular employees poorly, no matter how high corporate profits rise.
The consumption tax rate rises, amid corporate tax cuts.
Government and industry decided to build new nuclear power plants, despite the 2011 Fukushima nuclear disaster.
Corporations are not held responsible for the chemical pollution they cause.
In Japan today, the average person faces various difficulties that should be avoided by a properly functioning state. Why is this?
Recently, Japan’s ruling Liberal Democratic Party (LDP) has been repeatedly exposed for having slush funds; however, an even more deeply rooted structure has kept the LDP in power over many years. The party receives donations from major corporations and industry associations, and industry wishes are then reflected in policy. Although Japan has revised its law governing the control of political funds, it still does not prohibit donations from corporations or organizations.
Japan’s current politics — and the unfair burdens placed on citizens — are not a new development but rather an extension of the past. Tansa decided to investigate past corporate and group donations to the LDP.
To aid our investigation, we compiled a database of information stated in the National Political Association’s political funds reports. The National Political Association is a political funding organization that accepts corporate and group donations to the LDP.
Under the Political Funding Control Law, these political fund reports must be retained for three years. The Ministry of Internal Affairs and Communications says it destroys the National Political Association reports after the retention period had passed. The law, in a sense, prevents transparency of political funds.
Tansa obtained the reports’ information from official notices published by the Cabinet Office.
We will continue publishing articles on this issue. In this first installment, we trace the history of corporate donations to the LDP, as well as identify companies whose total contributions over the past half-century have exceeded 100 million yen (roughly $666,000).

Note on Tansa’s use of information
The data used in this series has been complied by Tansa from official notices. Among a total of roughly 160,000 pieces of data, we identified about 500 companies with the highest total donations. We combined data for companies in cases of company name changes, mergers, and subsidiaries based on the following criteria.
・Major subsidiaries listed in the latest annual securities reports
・Major mergers and name changes as listed in the company history section of the most recent annual reports
・For cases in which a given company has not submitted annual securities reports, we used information from its official website.
・Other cases where Tansa reviewed multiple supporting documents and determined that the companies in question were to be likely to be the same
There were some cases in which identical company names appeared in the official notices and which were difficult for us to determine as distinct from one another. In such cases, we combined only those that could be determined by reviewing supporting documents. Although the data has been carefully reviewed to ensure correctness, errors and omissions are possible, as we were able to confirm some differences in notation and typographical errors.
If you notice any errors, please let us know via Tansa’s contact page.
If you wish to use the data published in this series for journalistic or research purposes, etc., please ensure you cite the data as follows: Data compiled by Tansa in its series “Buying Policy.”
1974: Prime Minister Miki’s push to ban corporate funding
In the past, the LDP itself once moved to ban corporate donations.
In the House of Councillors election held in July 1974, the LDP almost lost its majority to opposition parties. The LDP had developed a system of “corporate-sponsored elections” and had placed major corporate groups in charge of funding and campaigning. Kakuei Tanaka was prime minister at the time.
The election was described as “8 wins, 7 loses,” meaning “if you spend 800 million yen, you win, and if you spend 700 million yen, you lose.” This kind of “plutocracy” faced criticism from the public. One journalist, Takashi Tachibana, traced the source of Prime Minister Tanaka’s funding, publishing his findings in the monthly magazine Bungeishunju. Prime Minister Tanaka resigned in December of that year.
After Tanaka stepped down, Takeo Miki took over as the next prime minister.
Miki was first elected to Japan’s House of Representatives in 1937 at the age of 30. Prior to the start of the Pacific War (World War II), he openly opposed going to war with the United States. After Japan’s capitulation in 1945, Miki joined a political party called the Cooperative Democratic Party, hoping to make use of unions of workers, small businesses, and farmers in politics. He joined the LDP when it was formed in 1955.
Just before assuming the role of prime minister in December 1974, Miki advocated for banning corporate donations. He said the following in a policy speech to the Diet in January 1975.
“To restore public confidence in our country’s politics overall, let us take a scalpel to the way elections and political funding are currently conducted. We are preparing to submit the necessary legislation to the Diet this session.”
However, Prime Minister Miki’s position quickly softened. Although the Political Funding Control Law was amended that year, it still did not prohibit corporate donations. It only imposed upper limits on corporate donation amounts based on company size.
In 1976, the Lockheed bribery scandals came to light. Former Prime Minister Tanaka was tried for accepting 500 million yen in bribes from the US corporation Lockheed for helping to facilitate the sale of Lockheed aircraft to Japanese airlines. Prime Minister Miki suggested opening an investigation into the scandal but was rebuffed by the LDP, his own party, which even pressured him into stepping down. In the end, Miki ended his term as prime minister after the LDP suffered major losses in that year’s election.
The 1988 Recruit scandal, and the LDP’s first fall from power in 1993
The following decades saw the LDP embroiled in further scandals. These included a 1988 scandal in which politicians received private shares of a Recruit subsidiary right before it went public, knowing the shares would rise; former LDP Vice President Shin Kanemaru was exposed for tax evasion in 1993; and corruption involving general contracting companies came to light that same year. In 1993, the LDP lost power for the first time since its inception.
The new coalition government, led by Prime Minister Morihiro Hosokawa, revised the Political Funds Control Law in 1994. It created a taxpayer-funded political party subsidy system, as well as banned corporate and group donations to individual politicians.
The amendment also included a measure to review the issue of corporate and group contributions to political parties after five years.
However, nothing changed even after the five years passed: Corporate and group donations to political parties continued. And the LDP regained power.
LDP Headquarters
1974: Keidanren Chairman Doko suggested ending its donation mediation
For many years, Nippon Keidanren — the Japan Business Federation — has been deeply involved in corporate and group donations to the LDP. It has encouraged its member companies to donate to the LDP since the latter was formed. Keidanren currently consists of 1,542 companies, mainly large corporations, as well as 106 industry associations and 47 local economic organizations.
However, Keidanran has generally hit pause on its political donation activities when the LDP becomes mired in funding scandals.
In the previously mentioned 1974 Upper House election, when election funding faced public criticism, Keidanren decided to stop “mediating” the allocation of donations from its member companies. Keidanren Chairman Toshio Doko made a proposal to Prime Minister Kakuei Tanaka.
In addition to his post at Keidanren, Doko was also chairman of electronics company Toshiba at the time. He later pushed for “fiscal restructuring without tax increases” during the administration of Prime Minister Zenko Suzuki (1980–982) and was called the “devil of administrative reform.” Doko was a penny pincher: He was rumored to sometimes only eat dried sardines as an accompaniment to his rice.
According to a National Political Association publication, at a press conference Doko said the following about ending Keidanren’s mediation activities.
“Currently, it is imperative for Keidanren to clear up the public’s misconception about collusion between the political and business worlds. The public is saying that politicians and businessmen are birds of a feather.”
“Keidanren should not be adjusting its hat under the plum tree,” he added, quoting an idiom that means “never invite suspicions needlessly.”

1993: Keidanren Chairman Hiraiwa said the federation would consider ending corporate donations
Again, 1993 saw former LDP Vice President Shin Kanemaru exposed for tax evasion, as well as a corruption scandal involving general contractors. As noted previously, these events contributed to the LDP’s first ever fall from power. This time, Keidanren — then under Chairman Gaishi Hiraiwa, chairman of Tokyo Electric Power Company (TEPCO) — presented the following policy.
“We will consider how to deal with corporate donations, including possibly ending them after a certain period of time.”
“In the meantime, each company or organization will make donations at its own discretion, and Keidanren will not act as a mediator.”
2004: Keidanren Chairman Okuda introduced policy scorecards
In 2003, 10 years after Chairman Hiraiwa expressed the above stance, Toyota Motor Corporation Chairman Hiroshi Okuda became chairman of Keidanren. Under Okuda’s watch, Keidanren pivoted from distancing itself from corporate donations to active involvement in politics through donations.
Keidanren “scored” each political party’s policies and their ability to implement them, and, based on these, called for donations from Keidanren member companies.
A transcript of a roundtable discussion with Keidanren leaders, including Chairman Okuda, was published in the January 2004 issue of Keizai Trend, Keidanren’s official publication.
“Under Chairman Hiraiwa, Keidanren decided to consider how it should handle corporate donations, including possibly ending them. Although Keidanren considered revising its policy several times since then, we never reached a conclusion. Politics has a big role to play in decisively implementing structural reform in Japan’s economic society, and I believe political donations are still necessary in order to encourage this. That’s why we have launched this initiative,” Okuda said.
Takahide Sakurai, then Vice Chairman of Keidanren’s Board of Trustees and chairman of Dai-ichi Life, spoke of the importance of repeating a process of “plan, do, see, and support.”
“We are saying that, for the first time, Keidanren will put out a kind of manifesto, and we are going to watch closely and evaluate whether or not[the politicians] follow it. We can’t just say our piece then take whatever [policy] comes back to us. By repeating the process of plan, do, see, and support, we will also brush up our own perspective on policies,” he said.
In January 2004, the month this round-table discussion was published, Keidanren scored 10 policy initiatives of both the LDP and the Democratic Party of Japan (DPJ) on a 5-point scale from A to E. The LDP outperformed the DPJ by a large margin in the results.
LDP
A: 1 policy initiative
B: 8 policy initiatives
C: 1 policy initiative
DPJ
A: 0 policy initiatives
B: 3 policy initiatives
C: 5 policy initiatives
D: 2 policy initiatives
2010: DPJ took power, Keidanren stopped calling for political donations
Although the LDP continued to score highly in Keidanren’s policy ratings, the LDP suffered major losses in the 2009 lower house election, and the DPJ came to power. The next year, Keidanren Chairman Fujio Mitarai, chairman of Canon, discontinued Keidanren’s evaluation of political parties and its calls for political donations from member companies.
2014: Under the Abe administration, Keidanren resumed calls for political donations
Keidanren’s calls for political donations, however, was revived when the LDP returned to power. At the time, Shinzo Abe was prime minister, and Keidanren was chaired by Toray Industries Chairman Sadayuki Sakakibara.
2023: Keidanren Chairman Tokura calls donations to LDP “social contribution”
In December 2023, current Keidanren Chairman Masakazu Tokura, also a director of Sumitomo Chemical, said the following at a press conference about political donations to the LDP.
“It costs to maintain democracy. Clean corporate donations to political parties are necessary social contributions.”
