Policy goals that define the partnership between Japan's ruling Liberal Democratic Party and coalition ally Nippon Ishin (Japan Innovation Party) are falling flat with voters, according to a survey conducted by The Asahi Shimbun and a research team led by Professor Masaki Taniguchi at the University of Tokyo.
The findings reveal a stark disconnect between the political agenda in Tokyo and public priorities. In questionnaires mailed in March and April to which 1,827 voters responded, only 1 percent chose constitutional reform as their top concern—the signature policy objective that Prime Minister Sanae Takaichi discussed with Hirofumi Yoshimura, the Nippon Ishin leader, after the LDP's overwhelming February Lower House election victory.
Instead, 38 percent of respondents prioritized pensions, medical care, and elderly care—pocketbook issues that dominate daily concerns across Japan's rapidly aging society.
The disinterest in constitutional revision cuts across party lines in unexpected ways. Even among LDP supporters, only 1 percent selected the Constitution as their priority—lower than the 5 percent of Conservative Party of Japan supporters and 3 percent of Democratic Party for the People backers. Supporters of parties traditionally positioned as constitutional defenders—the Social Democratic Party and Japanese Communist Party—registered higher percentages than LDP loyalists.
Watch what they do, not what they say. In East Asian diplomacy, the subtext is the text.
Nippon Ishin's flagship proposal to establish Osaka as a secondary capital also failed to gain broad traction. A combined 21 percent of all respondents supported the idea, while 33 percent opposed it. Even among LDP supporters, enthusiasm matched the overall response—revealing no coalition alignment effect. By contrast, a combined 50 percent of Nippon Ishin supporters backed the proposal.
The gap between party elites and their base emerged more clearly in a February survey of newly elected Lower House members. While a combined 86 percent of Nippon Ishin winners favored the secondary capital proposal, only 18 percent of LDP winners shared that view.
On parliamentary reform—specifically whether to reduce Lower House seats or cut lawmaker salaries—67 percent of Nippon Ishin supporters favored reducing seats, compared to 49 percent of LDP supporters.
The survey's timing amplifies its significance. Prime Minister Takaichi has staked considerable political capital on defense expansion and constitutional reform, positioning Japan as a more assertive regional security actor. The data suggest that voters remain focused elsewhere, even as geopolitical tensions with China and North Korea intensify.
For regional security architecture, the findings matter. Washington and allied capitals have welcomed Tokyo's shift toward collective self-defense and increased military spending. But sustained public indifference to these priorities could constrain Prime Minister Takaichi's ability to advance legislation—particularly constitutional amendments, which require not only supermajorities in both Diet chambers but also a national referendum.
The character 民 (たみ, tami, "people") grounds Japanese governance. When the people turn away, even the most powerful ruling party must recalibrate. The LDP has governed Japan for most of the postwar era, but these numbers suggest the current policy agenda sits uneasily with the electorate it claims to represent.
