閣僚辞任でも崩れぬ高市内閣を支える「防火壁」の正体

高市早苗たかいちさなえ首相しゅしょうが初はつ入閣にゅうかくさせた閣僚かくりょうが辞任じにんに追おい込こまれるという、政権せいけん発足ほっそく以来いらいの事態じたいに直面ちょくめんしながらも、内閣ないかく支持率しじりつの下落げらくは小幅こはばにとどまっている。自民党じみんとうが歴史的大勝れきしてきたいしょうを収おさめた2026年にせんにじゅうろくねん2月にがつの衆院選しゅういんせん小選挙区しょうせんきょくで落選らくせんし比例復活ひれいふっかつした簗和生やなかずお前農水相ぜんのうすいしょうは、「選挙せんきょでの強つよさ」を重視じゅうしするという首相しゅしょうの登用基準とうようきじゅんにそぐわないまま起用きようされていた。さらに、自身じしんを支援しえんしなかった首長しゅちょうの自治体じちたいの道路予算どうろよさんを「カットした」と発言はつげんしたことなどが問題視もんだいしされ、わずか1いっか月げつもたたずに辞任じにんした。

Even as it faces a situation unseen since the administration began with a minister appointed in Prime Minister Sanae Takaichi's maiden cabinet forced to resign, the decline in cabinet approval ratings has remained small. Former Agriculture Minister Kazuo Yana, who lost in his single-seat constituency in the February 2026 Lower House election—in which the LDP achieved a historic landslide—and only returned via proportional representation, had been appointed despite not meeting the prime minister's selection criterion prioritizing "electoral strength." Furthermore, after remarks such as claiming he "cut" road budgets for municipalities whose heads did not support him sparked controversy, he resigned in less than a single month.

Nにそぐわない= does not match / is not suited to; indicates that something does not conform to a standard, principle, or expectation.

閣僚かくりょうの資質ししつや首相しゅしょうの説明せつめいに批判ひはんが集中しゅうちゅうしたものの、各種かくしゅの世論調査よろんちょうさを見みる限かぎり、内閣支持率ないかくしじりつが大おおきく崩くずれたとは言いい難がたい。辞任前じにんまえに実施じっしされたNHKの調査ちょうさでは前月比ぜんげつひ2ポイント減げんの51％、時事通信じじつうしんでも1.7ポイント減げんの42.4％にとどまった。辞任後じにんごも、共同通信きょうどうつうしんや読売新聞よみうりしんぶん、朝日新聞あさひしんぶんなどの調査ちょうさで下落幅げらくはばは1〜4ポイント程度ていどに収おさまった。ANNが11.2ポイント減げんの47.1％とやや特異とくいな結果けっかを示しめした一方いっぽうで、FNN・産経新聞さんけいしんぶんでは1ポイント増ぞうの62.6％となるなど、多おおくの調査ちょうさで下落げらくは小幅こはばだった。

Although criticism concentrated on the minister's qualifications and the prime minister's explanations, as far as various opinion polls show, it is hard to say that cabinet approval ratings collapsed significantly. In an NHK poll conducted prior to the resignation, approval was 51%, down 2 points from the previous month, while in a Jiji Press poll it was 42.4%, down 1.7 points. Even after the resignation, polls by Kyodo News, the Yomiuri Shimbun, the Asahi Shimbun, and others showed declines contained to around 1 to 4 points. While ANN showed a somewhat atypical result with an 11.2-point drop to 47.1%, FNN and the Sankei Shimbun recorded a 1-point increase to 62.6%, demonstrating that in most polls the decrease remained narrow.

JX通信社つうしんしゃと選挙せんきょドットコムによる合同調査ごうどうちょうさでは、この問題もんだいが内閣ないかくの支持しじや不支持ふしじに「全まったく影響えいきょうしていない」「あまり影響えいきょうしていない」との回答かいとうが計けい55％を占しめた。影響えいきょうしなかった理由りゆうとして最もっとも多おおかったのは、「簗氏やなし個人こじんの問題もんだいであり内閣全体ないかくぜんたいや高市首相たかいちしゅしょうの問題もんだいではない」の16.8％で、「政策せいさくや実績じっせきで評価ひょうかすべき」の13.7％がそれに続つづいた。内閣ないかくを強つよく支持しじする層そうほど閣僚かくりょうの問題もんだいと首相しゅしょうへの評価ひょうかを切きり離はなす傾向けいこうがうかがえる。首相しゅしょう1人ひとりが内閣ないかくの「顔かお」である構造こうぞうそのものが、「首相しゅしょうと簗氏やなしは別べつ」ととらえさせ、首相しゅしょうの評価ひょうかを下さげない「防火壁ぼうかへき」として働はたらいたとみられる。

In a joint poll by JX Press and Senkyo.com, 55% of respondents answered that this issue "has not affected at all" or "has hardly affected" their support or disapproval of the cabinet. The most common reason cited for having no effect was "it is Mr. Yana's individual issue and not an issue with the entire cabinet or Prime Minister Takaichi" at 16.8%, followed by "they should be evaluated on policies and track record" at 13.7%. This indicates a trend where the more strongly a demographic supports the cabinet, the more they tend to separate ministerial scandals from their evaluation of the prime minister. The very structure in which the prime minister serves as the sole "face" of the cabinet appears to have worked as a "firewall" that led voters to perceive "the prime minister and Mr. Yana are separate," preventing a decline in her evaluation.

同調査どうちょうさによると、高市内閣たかいちないかくを「強つよく支持しじする」層そうは発足当初ほっそくとうしょの4割よんわり超ちょうから縮小しゅくしょうしたものの、最近さいきんも2割にわり台だい半なかばで推移すいいしている。石破茂内閣いしばしげるないかく発足時ほっそくじの1割いちわり程度ていどや、岸田文雄政権きしだふみおせいけんで5％程度ていどに落おち込こんだ事例じれいと比くらべても、コアな支持層しじそうの厚あつさは高市内閣たかいちないかくの大おおきな特徴とくちょうといえる。閣僚かくりょうを任命にんめいした首相しゅしょうの責任せきにんがなくなるわけではないものの、その責任せきにんを問とうことと支持しじを取とり下さげることは有権者ゆうけんしゃにとって必かならずしも同おなじではない。経済政策けいざいせいさくなどへの期待きたいが保たもたれる限かぎりは高たかい支持率しじりつを維持いじできる可能性かのうせいがあるが、今後こんごの政権批判せいけんひはんがそうしたコア層そうの期待きたいにどこまで作用さようするかが、政権運営せいけんうんえいの行方ゆくえを左右さゆうしそうだ。

According to the same poll, while the demographic that "strongly supports" the Takaichi cabinet has shrunk from over 40% at its inauguration, it has recently continued to hover in the mid-20% range. Even compared to the roughly 10% seen at the launch of the Shigeru Ishiba cabinet or the drop to around 5% under the Fumio Kishida administration, the depth of this core base is a major hallmark of the Takaichi cabinet. While this does not mean the prime minister's responsibility for appointing the minister is erased, holding her responsible and withdrawing support are not necessarily the same thing for voters. As long as expectations for economic policies and similar measures are maintained, it is possible for the cabinet to sustain high approval ratings, but the extent to which future criticisms of the administration impact the expectations of this core base is likely to determine the course of its governance.
