China's 99.2% Chip-Gas Tariff, and a Tax Pledge Tokyo Keeps Repeating

Beijing slaps a provisional 99.2% tariff on a semiconductor gas just as Tokyo repeats a familiar tax pledge; elsewhere, bidders keep raising and buybacks keep resetting.

China's Chip-Gas Tariff Squeeze

China's Provisional 99.2% Tariff Hits a Key Chipmaking Gas, Tokyo Protests

China's commerce ministry made a preliminary decision on September 7 to impose provisional anti-dumping tariffs of up to 99.2% on Japanese producers of dichlorosilane, a gas used to build the insulating film in semiconductor manufacturing. Japan's trade minister confirmed the decision at a press briefing the next day and said the ministry will work directly with the affected companies as the case proceeds.

Why it matters: The minister used the same briefing to escalate a separate, sharper complaint: Tokyo has protested Chinese export-control measures that apply only to Japan, and it is demanding their withdrawal. Two China trade frictions, arriving in the same week, aimed at the same relationship.

What to watch: The minister also updated the scorecard on a slower-moving story. The year-old US-Japan investment initiative has now reached roughly a fifth of its $550 billion target, after a US bank joined the financing for a gas-plant project. That pace, and whether the dichlorosilane dispute cools or escalates, will shape how much goodwill is left to draw on.

Tokyo's Tax Pledge, Rerun

Japan's Finance Minister Rules Out Deficit Bonds to Fund Food Tax Cut

Japan's finance minister used his September 8 post-cabinet briefing to repeat, almost word for word, a promise he has made since August: the planned two-year cut in the consumption tax on food and beverages to 1% will be funded through budget reform, not special deficit-financing bonds.

What changed: Nothing, and that is the point. The minister tied the funding pledge to the basic policy set out in an August 5 cabinet decision under the Takaichi government's budget reform drive, saying the stance "has not changed at all from the start."

Why it matters: A tax cut funded by trimming existing tax breaks and subsidies is a different fiscal animal than one funded by fresh borrowing. Holding the line on special bonds keeps the plan inside the government's own debt-to-GDP framework, at least on paper, and gives bond investors a marker to hold the ministry to.

Takeover Battles

Kakaku.com's Suitor Raises Bid to ¥3,680 a Share, Buys Three More Weeks

Kamgras 1 Kabushiki Kaisha, the EQT-backed vehicle bidding to take Kakaku.com private, raised its tender offer to ¥3,680 a share on September 10, up from ¥3,571, and pushed the deadline back three weeks to September 29.

What changed: It is the fourth price increase since the ¥3,000 opening bid in May, and it came with a matching rise in the price Kakaku.com itself will pay to buy back non-tendered shares after the squeeze-out, to ¥2,992 from ¥2,903.

Why it matters: The new price clears the ¥3,640 floor that shareholder Oasis said it needed to see, but Kakaku.com's board is still weighing the offer against a competing Bain Capital and LINE Yahoo proposal priced at ¥3,520, or ¥3,640 if it can lock in a non-tender deal with KDDI.

What to watch: On September 10 the board and special committee sent the rival proposers a letter asking whether they intend to raise their bid, a question that will decide whether this turns into a fifth round.

A Late Shareholder Pledge Resets the Minority Math in a ¥820 Bain Capital Buyout

Bain Capital's takeover vehicle, K.K. BCJ-110, amended its tender offer registration statement on September 11, revising the terms of its ¥820-a-share bid to take its target private. The trigger was a fresh shareholder commitment: a day earlier, a holder of 800,000 shares, 4.06% of the target and its fifth-largest shareholder as of the most recent half-year report, agreed to tender its entire stake and not withdraw it.

Why it matters: That single commitment lifts the pre-committed tender share to about 12.57% of the target, recalibrating the majority-of-minority threshold that determines whether the ¥820-a-share bid clears without resistance from remaining minority holders.

Earnings With a Catch

Sekisui House Profit Jumps 23% While International Profit Nearly Vanishes

Sekisui House's results for the six months to the end of July tell two different stories under one roof. Group revenue slipped 2.5% to ¥1.97tn, but operating profit rose 16.0% to ¥180.4bn, ordinary profit rose 23.8% to ¥169.1bn, and net profit attributable to shareholders climbed 23.1% to ¥125.1bn.

What changed: Strong urban-redevelopment sales and property disposals to Sekisui House REIT Investment Corporation drove the profit gain even as the top line shrank from ¥2.02tn a year earlier.

The catch: The international segment, mostly US operations, saw operating profit collapse 93% to about ¥1.0bn as American buyer hesitancy and heavier sales incentives squeezed margins.

Why it matters: A homebuilder making noticeably more money from a smaller top line is either disciplined capital allocation or a warning that the growth engine is running low on fuel; the US collapse suggests it is some of both.

Governance Under Pressure

Chubu Electric Receives Report on Its Flawed Hamaoka Seismic Assessment, Withholds Release

Chubu Electric Power said on September 11 that it has received the findings of an eight-month independent investigation into how the utility evaluated ground motion at its Hamaoka Nuclear Power Station, an assessment the company itself had already disclosed was carried out using an improper method.

What changed: An outside panel with no ties to the company completed its review of the reference earthquake motion calculations for Hamaoka Units 3 and 4.

The catch: Chubu Electric says only a redacted version of the report will be published later, and it still cannot quantify any hit to earnings from the episode.

Why it matters: A utility that got the seismic math wrong on a nuclear plant, then won't fully release the report on how it happened, is asking investors and regulators to trust a process they can't see.

Sony Life Fraud Toll Reaches ¥56.4mn as FSA Gives Inspection Notice

Sony Life Insurance says its months-long review of sales-staff conduct has confirmed further cases of client fraud, pushing the cumulative tally of confirmed insurance-related theft to ¥56.4mn from 21 customers, alongside a separate pool of improper money transfers now totaling ¥124.2mn from 17 customers.

What changed: The insurer, a unit of Sony Financial Group, disclosed the update on September 11 covering its "customer verification" exercise as of the end of August, and confirmed the Financial Services Agency has given notice of an on-site inspection.

Why it matters: The fraud tally has grown with each update rather than stabilizing, and the company is simultaneously winding down its exclusive-agency sales channel, the same channel where a separate finding showed seven agencies introduced outside investment products without required prior notification.

Capital and Listings

MUFG Sells ¥200bn of Perpetual Bonds That Can Be Written Down to Almost Nothing

Mitsubishi UFJ Financial Group is borrowing ¥200bn through bonds that never mature and can lose their entire face value if the bank's capital position weakens enough.

What changed: The filing, lodged September 11, covers two tranches of unsecured perpetual subordinated bonds paying fixed coupons of 3.311% and 4.072% before floating over yen Tibor.

The catch: The fine print lets MUFG cancel principal outright, not merely defer it, if its core capital ratio drops below 5.125%, with no guarantee of recovery for bondholders.

Why it matters: These instruments count as capital precisely because they can absorb losses; investors buying the yield are also buying the risk that a capital shortfall wipes out their principal, not just their coupon.

KOMPEITO Lists on TSE Growth With a Forecast Swing to Profit

KOMPEITO, which runs the installed office fresh-food subscription service OFFICE DE YASAI, listed on the Tokyo Stock Exchange's Growth market on September 11 and released an earnings forecast alongside the listing.

What changed: The numbers show a company crossing from loss into profit: revenue of ¥9.87bn for the year through August, up 72% from ¥5.74bn a year earlier, operating profit of ¥880mn against an operating loss of ¥225mn, and net profit of ¥1.13bn against a net loss of ¥161mn.

Why it matters: The nine months to May had already turned positive, with revenue of ¥7.05bn and operating profit of ¥671mn, so the full-year forecast extends a trend already visible before the listing rather than hoping one appears.
