Japanese Company Affiliates Challenge Trump-Era Tariffs in US Court
Dec. 4, 2025 | Governance & Law

Affiliates of Japanese firms are contesting the Trump administration’s additional tariffs, arguing that the measures exceeded presidential authority.

**US affiliates of nine Japanese companies—including Toyota Tsusho Corp, Sumitomo Chemical Co., Ricoh Co., Yokohama Rubber Co., Ushio Inc., NGK Insulators Ltd., Kawasaki Motors Ltd., Yamazaki Mazak Corp and Proterial Ltd.—have filed lawsuits in the US Court of International Trade seeking full refunds for tariffs they paid in 2025.**
They argue that the levies, imposed under the International Emergency Economic Powers Act without congressional approval, exceeded the act’s scope by authorizing “reciprocal” or sector-wide tariffs on imports from China, Canada, Mexico and other nations.

**These filings follow Supreme Court oral arguments in November, during which justices questioned whether the president could invoke a 1970s-era emergency law to bypass Congress when imposing high tariffs on national-security grounds.**
Lower courts previously ruled that the Trump administration overstepped its authority by using IEEPA to penalize countries for insufficient cooperation on fentanyl trafficking, rather than to address a direct threat to US national security.

**The Japanese affiliates note that even if the Supreme Court voids the tariffs, importers would not automatically receive refunds.**
They ask the Court of International Trade to declare the tariffs illegal, block any new reciprocal levies and ensure full repayment if the high court strikes down the measures.

**The timing of the Supreme Court’s decision remains uncertain, and legal experts warn that an invalidation could trigger a protracted, complex refund process spanning several years.**
Meanwhile, other entities—such as US retailer Costco Wholesale Corp—have filed their own suits to recover duties paid under the same Trump-era tariff schedules.
LDP Moves to Reduce House Seats and Redraw Electoral Districts
Dec. 4, 2025 | Politics

Japan’s Liberal Democratic Party has proposed reducing the total number of seats in the House of Representatives from 465 to 420 or fewer and redrawing electoral districts based on updated population data.

**The draft legislation tasks an electoral system council—including representatives from all parties in the House—with deciding the precise methods for seat reduction, and it requires lawmakers to enact the necessary legal measures within one year of the law’s passage.**
If the parties fail to reach agreement within twelve months, an automatic reduction clause would eliminate 25 single-member constituencies and 20 proportional representation seats. In that event, the national Council for the Delimitation of Constituencies would use 2025 census figures to redraw district boundaries within one year, potentially paving the way for elections under the new structure by December 2027.

**During an LDP meeting on December 2, 2025, members raised objections to the automatic reduction clause, leading party leaders to delay final approval until the next day.**
Former Foreign Minister Takeo Iwaya criticized the process as rough and urged removal of the clause due to insufficient internal dialogue. Secretary-General Shun’ichi Suzuki defended the one-year review period and the 10 percent reduction target, noting public backing for seat cuts and previous comments by Constitutional Democratic Party leader Yoshihiko Noda. Ahead of that meeting, LDP negotiators and representatives of the Japan Innovation Party agreed to accelerate internal approvals and submit the bill during the current Diet session, though some LDP members still question whether the party can muster the necessary support.

**Two LDP calculations project that single-member districts would drop from 289 to 264 and proportional representation seats from 176 to 156.**
Both estimates apply the Adams method to align seat allocations with prefectural population ratios, targeting cuts in 20 prefectures. Under each plan, Tokyo would lose three single-member seats, Kanagawa, Chiba, and Osaka would each lose two, and smaller prefectures such as Akita, Toyama, and Kagawa would see districts reduced from three to two. All 11 proportional representation blocks would lose between one and three seats, with the exact numbers depending on whether the adjustments use the 2020 census or the 2025 Basic Resident Register data.

**Analysts warn that these reforms would increase disparities in vote weight across prefectures, raising the ratio of the most to the least populous districts from 1.7 to about 1.86.**
Post-reform, Chiba would have the highest population per representative at roughly 510,183, while Tottori would have the lowest at about 274,383. Critics argue that widening these gaps could further weaken rural influence and undermine voter equality. Former Prime Minister Shigeru Ishiba has opposed seat reductions and cautioned that returning to multi-member districts might stoke political conflict, reflecting the broader debate over fair representation and electoral balance.

China unleashes diplomatic campaign to isolate Japan amid Taiwan row

Japan Times | English | News | Dec. 5, 2025 | Geopolitical Conflict and Disputes

China has intensified its diplomatic efforts to isolate Japan amid an ongoing dispute over Japanese Prime Minister Sanae Takaichi's comments on Taiwan. Chinese Foreign Minister Wang Yi met with Russian officials Sergey Lavrov and Sergei Shoigu in Moscow, where both countries expressed a shared stance against Japan.

During the talks, China and Russia agreed to enhance their strategic coordination, particularly on issues related to Japan. They jointly criticized Japan for what they described as increasing militarism and reaffirmed their commitment to upholding the outcomes of World War II. Both countries opposed any attempts to whitewash Japan's colonial aggression or revive fascism and militarism.

First Meeting of the Committee to Review Flood Lessons Aims to Copy Japan's Homework

Thai Post | Local Language | News | Dec. 5, 2025 | Extreme Weather Events

On 4 December 2025, the first meeting of the Committee to Review Lessons and Prepare for Handling a Major Flood was held at the Government House, chaired by Prime Minister Anutin Charnvirakul. The meeting was initially opened by Deputy Prime Minister Bawornsak Uwanno, who emphasized that despite Thailand’s comprehensive disaster laws and agencies, command authority and decision-making do not function effectively during sudden emergencies. The committee aims to study flood events, particularly from Songkhla province and 2011 floods, to develop practical manuals and systems for future disaster readiness.

Bawornsak highlighted the importance of learning from Japan’s disaster management approach, especially its regular rehearsals and training, to reduce damage. The committee involves deputy prime ministers, civil servants, and experts working as a technical team to create usable guidelines to be followed by public sector officials during emergencies. After Bawornsak’s introduction, Prime Minister Anutin took over the meeting leadership.

Additional points covered included the Prime Minister rejecting political rumors related to flood casualties, asserting transparency and trust in official death toll figures. He stressed the importance of national dignity and security regarding border issues with Cambodia and outlined the Internal Security Operations Command’s focus for 2026 on sustainability, modernization, and community cooperation. Furthermore, the Chinese ambassador donated over 30 million baht for southern flood relief, reaffirming strong Thailand-China ties and confidence in rapid recovery under Anutin's leadership.

2025年度の年金額は1.9%の増額だが、現役賃金より0.4%低い伸び-年金額改定の意義と2026年度以降の見通し(3)

The 2025 Pension Amount Increases by 1.9% but Grows 0.4% Less Than Active Wages – The Significance of Pension Amount Revisions and Outlook Beyond Fiscal 2026 (3)

NLI Research Institute | Local Language | AcademicThink | Dec. 5, 2025 | UndeterminedWages and Compensation

For fiscal 2025, pension amounts increased by 1.9%, reflecting a 2.7% rise due to price increases from the previous year, but this was offset by a macro-economic slide adjustment of –0.4%, resulting in a net real decrease. The revision process incorporates price increases immediately, while real wage changes are averaged over two to four years, mitigating recent wage declines. The macro-economic slide, designed to ensure pension financial soundness amid demographic challenges, was fully applied, dampening pension growth relative to active wages.

The pension revision rules aim to balance the interests of retirees and the working generation, with the macro-economic slide introduced to address issues like low birth rates and increased longevity by controlling contribution rates. Despite consecutive nominal increases over three years, pensions have declined in real terms each year, and pension growth remains lower than wage growth. This gap underscores the financial pressures on elderly households dependent mainly on public pensions as their income source.

Looking ahead to fiscal 2026, pension amounts are expected to be announced in January 2026, with ongoing price increases making the trend in pension revisions a critical focus. The mechanisms for revision effectively smooth out short-term wage and contributor fluctuations, but the overall trend suggests that pension amounts will continue to lag behind wage growth, signaling ongoing challenges for pension policy and financial sustainability beyond 2026.
