October 29 Legislative Report: Japan Addresses IRBM Threats
Chief Cabinet Secretary Discusses IRBM Response at Lower House Budget Committee as Security Strategy Talks Begin
Japanese Chief Cabinet Secretary Hayashi Yoshimasa formally outlined how Japan plans to respond to intermediate-range ballistic missile (IRBM)-class threats during a session of the House of Representatives Budget Committee. He was answering questions related to the national security strategy. The fact that missile defense came up on the budget committee's fiscal deliberation stage is seen as evidence that Japan is tying its defense buildup and budget planning into a single stream. A member of the Liberal Democratic Party (LDP) and a core figure in the Japanese Cabinet, Hayashi serves as the government's chief spokesperson, responsible for communicating the administration's security and fiscal policy positions.
Background of the Remarks and the Legislative-Fiscal Context
The remarks came in the form of parliamentary question-and-answer exchanges. The Lower House Budget Committee is the key battleground where opposition probing clashes with the government's defense of its policies during the annual budget review. IRBMs are ballistic missiles capable of flying intermediate ranges or farther, and as missile capabilities of neighboring countries such as North Korea expand, they have become an unavoidable item in Japan's defense debate. Hayashi's explanation of threat response measures before the budget committee reaffirms that missile defense capabilities are directly tied to budget acquisition. Building interception systems and strengthening early-warning surveillance capabilities ultimately come down to cost.
Contrasts with the Korean National Assembly
Around the same time, the Korean National Assembly was moving in a different legislative direction. Rep. Lee Kang-chul of the Rebuilding Korea Party joined in sponsoring a prosecutorial reform bill to separate the prosecution's investigative and indictment powers, and also co-sponsored the re-introduction of the 'Kim Kun-hee Special Prosecutor Act' with fellow party members. With individual lawmakers filing bills in succession, judicial and prosecutorial reform is emerging as the central axis of the opposition's legislative strategy.
Committee activity is also in full swing. According to publicly available National Assembly information, a number of lawmakers, including Rebuilding Korea Party members Park Chan-min, Han Sang-kyun, Cho Hyun-moon, Cho Hyun-joon, Lee Kang-chul, Kim Deok-il, Tak Hyun-min, Shim Ga-hyun, and Lee Jung-won, along with Democratic Party Rep. Gong Jin-sung, have been assigned to the Special Committee on Budget and Accounts and the Education Committee. Rep. Park Chan-min, as a member of the Special Committee on Budget and Accounts, participated in the review of the 2025 government budget, and as a member of the Education Committee also took part in school-related audits of government offices. Rep. Gong Jin-sung likewise examined the education community's demands during the Education Committee's audit. Budget review and government audits—the two pillars—are filling out the Assembly's substantive schedule for October and November.
Implications and Outlook
While Hayashi's remarks did not include specific figures for increased defense spending, they are significant in that Japan is designing its security strategy and fiscal management in parallel. Responding to IRBM-class threats inevitably entails major investments such as deploying interceptor missiles and surveillance radars, and this will offer clues to the future direction of Japan's defense budget.
On the Korean side, with judicial reform bills such as prosecutorial reform and the special prosecutor act progressing alongside budget deliberations, competition over legislative priorities is expected to intensify in the latter half of the regular session. Given that most bills remain at the stage of being referred to their competent standing committees, the pace of review will likely determine legislative outcomes. Since defense and security policy is ultimately completed through budget allocation, Hayashi's budget committee response is viewed as an event that reaffirmed that finance is the starting point of security strategy.
