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.

Hong Kong to set up independent panel to probe high-rise fire

NHK | English | News | Dec. 4, 2025 | Accidents

Hong Kong Chief Executive John Lee announced the formation of an independent, judge-led panel to investigate accountability for a recent fire that affected seven high-rise apartment buildings. The fire resulted in at least 151 deaths and left over 30 people missing.

Investigations revealed that non-fire-retardant protective nets were used during renovation work. More than ten individuals, including company executives responsible for the maintenance, have been arrested. There are also increasing demands to hold the government accountable for oversight failures.

John Lee emphasized that the investigation will be comprehensive, with anyone found responsible being held accountable. He also stated that safety standards and supervision systems will be reviewed. Despite the tragedy, he confirmed that legislative elections will proceed as planned on Sunday.

Japan Finance Chief Denies Gap in Economic Views between Govt, BOJ

Nippon | English | News | Dec. 4, 2025 | UndeterminedEconomic Growth

Japanese Finance Minister Satsuki Katayama stated that there is no difference in economic outlook between the Japanese government and the Bank of Japan (BOJ), both viewing the domestic economy as moderately recovering. This alignment is significant for the BOJ's potential decision on an interest rate hike.

BOJ Governor Kazuo Ueda indicated that the central bank will decide on adjusting its policy interest rate at the December 18-19 monetary policy meeting. He referenced improving conditions, including reduced uncertainties about the U.S. economy and the impact of U.S. tariff policies.

The comments signaled to financial markets that the BOJ may soon raise interest rates again, following the last hike in January 2025. Katayama emphasized the government's expectation for the BOJ to steer monetary policy to achieve a stable 2 percent inflation rate alongside wage growth.

日本政府は中国のG7招待で慎重な対応求める議長国の仏に伝達、マクロン大統領3日訪中

Japanese government urges cautious response to China's G7 invitation, conveys to French presidency; President Macron to visit China on the 3rd

The Sankei News | Local Language | News | Dec. 4, 2025 | Shifting Geopolitical Alliances

The Japanese government has urged a cautious approach to French President Emmanuel Macron’s proposal to invite Chinese President Xi Jinping to the 2026 G7 summit in Évian, France. Japan's concern stems from China not sharing the G7's core values, such as freedom, democracy, and the rule of law. The recommendation was conveyed to the French presidency to ensure careful consideration of the potential implications.

President Macron is scheduled to visit China on December 3rd, where he is expected to discuss the invitation to the G7 summit. Macron has shown longstanding interest in inviting Xi, and reports suggest Germany also supports this idea. Macron’s motivation may include bolstering his administration's standing amid recent electoral losses and low approval ratings by showcasing strengthened economic and diplomatic ties with China.

Japan, the only Asian G7 member, has historically expressed concerns about China’s maritime expansion and economic coercion. Japanese leaders emphasized the importance of G7 engagement in the Indo-Pacific region at the 2025 summit. There is apprehension within the Japanese government that Xi’s presence could hinder frank discussions about China among G7 members. Despite these concerns, Japan maintains close communication with France, which reportedly understands Japan’s position.
