In early February 2023, the son of Japan’s former defense minister Nobuo Kishi, Nobuchiyo Kishi announced that he would run for a parliamentary seat. He will inherit the electoral constituency of his father, who announced his retirement from politics only days before.
Nobuchiyo is a classic example of the hereditary politics still entrenched in Japan’s political system. On February 14, 2023, Mainichi Shimbun reported that Nobuchiyo had felt compelled to take down his family tree from his website homepage because of criticism of its hereditary symbolism.
Hereditary politicians, called seshu, are those whose family members serve as politicians, train their inheritors and pass on their political capital accumulated over decades.
Coming from a renowned Liberal Democratic Party (LDP) political family in Japan’s rural Yamaguchi prefecture, Nobuchiyo Kishi is almost guaranteed to succeed in the by-election on 23 April. His great-grandfather Nobusuke Kishi and uncle Shinzo Abe were two prominent prime ministers. Nobuchiyo is also closely related to a third prime minister, Eisaku Sato – and to Shintaro Abe, who was foreign minister and the father of Shinzo Abe.
In 2022, Prime Minister Fumio Kishida appointed his eldest son Shotaro as his executive secretary for political affairs, a move that has come under criticism. Shotaro’s appointment is again in the spotlight after a trip with his father to London where he allegedly misused his official car for shopping purposes.
It is clear that Kishida is preparing his eldest son to inherit his political assets and run for a parliamentary seat. In light of this obvious favoritism, the Japanese media have adopted the English-derived term “nepobaby,” meaning nepotism baby.
Political inheritance is neither new nor unique to Japan. Hereditary politicians are not uncommon in industrialized democracies, including the United States — the Kennedy family being the leading example. The prime minister of Canada, Justin Trudeau, is also the eldest son of Pierre Trudeau, Canada’s former prime minister.
In many Asian countries — both democratic and non-democratic — political families have dominated politics and government. India’s Nehru-Gandhi family is a case in point.
Singapore’s Lee Hsien Loong, who has served as prime minister for close to twenty years since 2004, is the eldest son of the late Lee Kuan Yew, prime minister from 1959–90.
The current Philippine President Ferdinand Marcos, Jr, comes from a political family, too.
Park Chung-hee, the father of South Korea’s first female president Park Geun-hye, served as President from 1963–79.
Non-democratic systems also tend toward hereditary rule. In North Korea, the Kim family monopolizes power.
But the extent of political nepotism in Japan — a modern and industrialized country — remains unmatched. Rather than showing signs of weakening, it has strengthened in recent decades. In 1960, only 3% of Japanese members of parliament were hereditary politicians. Despite political attempts at reducing their power, their share has swollen to 30% today.
Most of Japan’s postwar prime ministers, including Kishida, have come from political families. Potential future prime ministers, such as Taro Kono and Shinjiro Koizumi, are hereditary politicians. Yoshihide Suga, Kishida’s predecessor, was an exception in recent years.
In its 2009 election manifesto, the Democratic Party of Japan (DPJ) announced it would ban immediate family members from inheriting constituencies. Ironically, its first Prime Minister, Yukio Hatoyama, came from a political dynasty. But the other two DPJ prime ministers, Yohihiko Noda and Naoto Kan, did not come from political families.
Although the LDP has the highest percentage of hereditary politicians, the main opposition party — the Constitutional Democratic Party of Japan, successor to the DPJ — also has hereditary parliamentarians, albeit only 6%. Neither the LDP’s junior coalition partner Komeito nor the Communist Party of Japan has any such representatives in the national parliament.
Hereditary politicians inherit the valuable resources: jiban, or the network of local support groups and organizations; kanban, or name recognition, such as the Kishi or Koizumi families; and kaban, or financial support through the network and the faction to which a hereditary politician belongs. The electoral success of hereditary politicians is much higher than non-hereditary candidates. A Nikkei Asia longitudinal study notes that “candidates connected by blood or marriage have an 80% chance of winning,” while only about 20% of first-time candidates win.
This tradition of politics as a family business continues, with many legislators being third- and fourth-generation parliamentarians. Nobuchiyo will be a fourth-generation politician. There are many third-generation parliamentarians in key government and party posts, including Prime Minister Kishida himself.
Many key ministers in the Kishida Cabinet are also hereditary politicians. Foreign Minister Yoshimasa Hayashi is the son of former finance minister Yoshiro Hayashi. Defense Minister Yasukazu Hamada is the son of Koichi Hamada, a notorious LDP lawmaker who admitted to being a yakuza — a member of Japan’s mafia-like criminal organizations.
Finance Minister Shunichi Suzuki’s father, Zenko Suzuki, served as prime minister from 1980-82. Digital Transformation Minister Taro Kono’s father was foreign minister and his grandfather, Ichiro Kono, served as Japan’s deputy prime minister.
Some voters see hereditary politics in a negative light, but they also appreciate such politicians bringing more pork projects to their districts than non-hereditary politicians. Politics as a family business remains one of Japan’s most robust and thriving industries.
