石破茂首相と鉄道政策──新幹線外交の裏で見える国内インフラの課題/Japanese Politician Shigeru Ishiba, a Railway Enthusiast, and His Railway Policy — Domestic Infrastructure Challenges Behind Shinkansen Diplomacy

石破茂首相と鉄道政策──新幹線外交の裏で見える国内インフラの課題

20258月末、インドのモディ首相が来日し、石破茂首相とともに東北新幹線「はやぶさ」に乗車するという象徴的なイベントが行われました。仙台までの約1時間半、両首脳は鉄道について語り合い、日本の新幹線技術の安全性や快適性をアピール。インドで建設中の高速鉄道への技術導入を視野に入れた外交的な演出でした。

このような国際的な鉄道外交が注目される一方で、国内の鉄道インフラ、とりわけ赤字地方路線や並行在来線の問題は依然として深刻です。鉄道ファンや地域住民からは「石破首相は鉄道好きなのに、国内政策には何もしていない」との声も上がっています。

公明党の鉄道政策──実績と限界

鉄道行政を所管する国土交通省のポストは長年公明党が担っており、斉藤鉄夫氏が大臣を務めた時期には以下のような政策が推進されました。

バリアフリー化の推進

  • ホームドアの設置拡大(都営地下鉄・JR山手線など)
  • 段差・隙間の縮小(2030年度までに4000番線対象)
  • 精神障がい者への運賃割引制度の導入(JR6社・大手民鉄9社)

地域公共交通の維持・再構築

  • 上下分離方式の全国展開(JR只見線の復旧など)
  • JR北海道・四国・貨物への経営支援
  • 地域公共交通活性化再生法の改正と1300億円の予算確保

サービス向上と人材確保

  • 無人駅・みどりの窓口のサービス改善
  • 運転手不足対策と交通労働者の待遇改善
  • DX化(キャッシュレス・MaaS・自動運転)

インフラ整備と安全対策

  • 都市鉄道の高架化・延伸(竹ノ塚駅など)
  • 女性専用車両の導入
  • 高速道路料金所の撤廃による渋滞緩和

これらの取り組みは一定の成果を上げているものの、都市部偏重の傾向が強く、赤字地方鉄道や並行在来線の抜本的な再構築には踏み込めていないという批判もあります。

森山健一(筆者)の見解──鉄道政策への本気度が問われる

石破茂氏は鳥取県という地方出身であり、鉄道好きの政治家として知られています。しかし、今回の新幹線乗車イベントを見ても、鉄道政策に真剣に取り組んでいるという印象は薄く、ただの「電車好きのキッズ」のように映ってしまうのが残念です。

もちろん、鉄道行政は国土交通省の管轄であり、そのポストを公明党が長年握っているため、首相として口出ししにくい事情は理解できます。しかし、鉄道事業は都市部の路線や運賃以外の収益(広告・商業施設など)でしか利益を出しにくい構造であり、だからこそ政治的な支援が不可欠です。にもかかわらず、石破政権はその点を曖昧にしたままです。

公明党も近年は鉄道政策に言及していますが、マニフェストと実態が乖離している部分があります。岐阜の路面電車廃止に関しては、公明党が「元凶」とされることもあり、近年では渋滞緩和のために路面電車復活を示唆するなど、政策の一貫性に疑問が残ります。

都市鉄道は放っておいても利用者が多く、収益も見込めます。だからこそ、政治が取り組むべきは赤字ローカル線、特にJRの地方路線や並行在来線問題です。地域の足を守るために、鉄道政策を「趣味」ではなく「国家戦略」として本気で取り組む姿勢が求められています。

鉄道は単なる移動手段ではなく、地域の命綱であり、経済・観光・安全保障にも直結する重要なインフラです。石破政権と公明党がこの分野でどれだけ本気になれるか──それが今後の日本の交通政策の分岐点になるでしょう。

Japanese Politician Shigeru Ishiba, a Railway Enthusiast, and His Railway Policy — Domestic Infrastructure Challenges Behind Shinkansen Diplomacy

At the end of August 2025, Indian Prime Minister Modi visited Japan and, together with Prime Minister Shigeru Ishiba, participated in a symbolic event by riding the Tohoku Shinkansen “Hayabusa.” During the approximately one and a half hour journey to Sendai, the two leaders discussed railways and showcased the safety and comfort of Japanese Shinkansen technology. This diplomatic gesture was aimed at introducing high-speed railway technology to India, where such a railway is currently under construction.

While this kind of international railway diplomacy attracts attention, serious issues remain with domestic railway infrastructure—especially deficit-ridden rural lines and parallel conventional lines. Railway enthusiasts and local residents have voiced concerns, saying, “Even though Prime Minister Ishiba is a railway enthusiast, he hasn’t done anything for domestic policy.”

Komeito’s Railway Policy—Achievements and Limitations

The post overseeing railway administration at the Ministry of Land, Infrastructure, Transport and Tourism has long been held by the Komeito party. During the tenure of Minister Tetsuo Saito, the following policies were promoted:

l   Promotion of barrier-free initiatives

l   Expansion of platform door installations (such as on the Toei Subway and JR Yamanote Line)

l   Reduction of platform gaps and steps (targeting 4,000 platforms by fiscal 2030)

l   Introduction of fare discount systems for individuals with mental disabilities (by six JR companies and nine major private railways)

l   Maintenance and reconstruction of regional public transportation

l   Nationwide rollout of the vertical separation model (such as the restoration of JR Tadami Line)

l   Management support for JR Hokkaido, Shikoku, and freight operations

l   Revision of the Regional Public Transportation Revitalization Act and securing a budget of 130 billion yen

l   Service improvement and workforce development

l   Improvement of services at unmanned stations and “Midori no Madoguchi” ticket offices

l   Measures to address driver shortages and improve working conditions for transportation workers

l   Digital transformation (cashless payments, MaaS, autonomous driving)

l   Infrastructure development and safety measures

l   Elevation and extension of urban railways (such as Takenotsuka Station)

l   Introduction of women-only cars

l   Elimination of highway toll booths to alleviate congestion

Although these initiatives have produced certain results, there is criticism that they are heavily focused on urban areas and have not fundamentally restructured deficit-ridden local railways or parallel conventional lines.

Kenichi Moriyama’s Perspective—Questioning the Commitment to Railway Policy

Shigeru Ishiba is known as a politician from Tottori Prefecture—a rural region—and as a railway enthusiast. However, even after the recent Shinkansen event, he does not give the impression of being serious about railway policy, and it is disappointing that he seems more like a “train-loving kid.”

Of course, railway administration falls under the jurisdiction of the Ministry of Land, Infrastructure, Transport and Tourism, and given that the Komeito party has long held this post, it is understandable that the Prime Minister might hesitate to intervene. However, the railway business structure means that only urban lines and non-fare revenue streams (such as advertising and commercial facilities) are generally profitable, making political support essential. Despite this, the Ishiba administration remains ambiguous on this point.

Komeito has also addressed railway policy in recent years, but there are discrepancies between its manifestos and actual practice. In the case of the abolition of Gifu’s streetcar, Komeito was labeled the “culprit,” and recently, the party has suggested reviving streetcars to alleviate congestion—raising questions about the consistency of its policies.

Urban railways naturally attract many users and generate revenue. Therefore, politics should focus on deficit-ridden local lines, especially JR’s rural routes and parallel conventional lines. To protect local lifelines, railway policy must be approached not as a “hobby,” but as a serious “national strategy.”

Railways are not just a means of transportation; they are vital lifelines for communities and are directly linked to the economy, tourism, and national security. How seriously the Ishiba administration and Komeito party will address this area will be a turning point for Japan’s future transportation policy.
