关键数据显示年轻族群对 Sanae Takaichi 的个人支持度极高：部分民调中 18–29 岁支持度接近 90%。NHK 在她上任后的调查显示，18–39 岁对她的支持率为 77%，高于前任 Shigeru Ishiba 与 Fumio Kishida 就任初期的 38% 与 51%。政治资料网站分析亦指向流量差异：7–11 月间与她相关的 YouTube 影片观看量明显超过各政党个别内容，她于 10 月就任时的 YouTube 关注度约为 Sanseito 在夏季参院选人气高峰的 3 倍，暗示她的财政支出与国安讯息，加上更尖锐的社群操作，正在从 Sanseito 与 Democratic Party for the People（DPP）等政党回收部分年轻支持。
但「个人好感」未必等同「政党投票」：即使在年轻族群中，执政党 LDP 支持度仍约 30%，显示对 Sanae Takaichi 的评价与对联盟的支持存在落差。结构面上，日本约 30% 议员为世袭政治人物，而美国与德国低于 10%；她以非世袭背景对比特权政治，强化「工作胜于出身」叙事。投票率仍是风险：年轻投票通常偏低，且 2 月 8 日寒冷天候并与考季、春假重叠可能压抑出门投票；同时，2025 年 7 月参院选中 20 多岁后段投票率升至 52%，较 2022 与 2024 的全国选举约高 14 个百分点，显示兴趣上升但仍受社群媒体带来的意见波动与快速翻转所影响。
Japan’s first female prime minister, Sanae Takaichi, has spent her first three months using high-visibility social media tactics to connect with younger voters: selfies with foreign leaders, public drum performances, and viral consumer demand for items like her handbags and pink pens. She contrasts herself with old-guard politics by emphasizing policy study at home over closed-door elite socializing. Her youth popularity will be tested in the Feb. 8, 2026 lower-house election.
The numerical indicators in the article show unusually strong personal support among the young: some polls put backing among ages 18–29 at nearly 90%. An NHK survey taken right after she took office reported a 77% approval rating among ages 18–39, versus 38% and 51% for immediate predecessors Shigeru Ishiba and Fumio Kishida at the start of their terms. Social-media metrics reinforce the gap: July–November YouTube views tied to Takaichi far exceeded those for individual parties, and when she became prime minister in October, YouTube interest was about triple the scale of Sanseito’s summer upper-house surge, suggesting her simpler fiscal-spending and national-security message and sharper online strategy are pulling support from Sanseito and the Democratic Party for the People (DPP).
Constraints remain that could decouple personal approval from electoral outcomes: even among younger voters, support for the ruling LDP sits around 30%, implying a split between liking Takaichi and backing her coalition. Structurally, about 30% of Japanese lawmakers are hereditary politicians, compared with below 10% in the US and Germany; Takaichi leverages her non-dynastic background to reinforce a work-over-privilege narrative. Turnout is a key risk: youth participation is typically lower, and the Feb. 8 vote overlaps with cold weather, exams, and spring break; at the same time, turnout among people in their late 20s rose to 52% in the July 2025 upper-house election, about 14 percentage points higher than national races in 2022 and 2024, indicating rising interest but still vulnerable to fast social-media-driven volatility.
