Kioxia and SanDisk's ¥5tn Ask, With a Government String Attached
Kioxia and SanDisk want ¥5tn for Japanese chip plants by 2032, if Tokyo pays its share. Meanwhile Kakaku.com's suitor sweetened its bid by exactly one yen, because apparently that's how you win a standoff.

Kioxia and SanDisk's ¥5tn Wager on Japan

Kioxia and SanDisk Set ¥5tn Japan Investment Target Through 2032, With a Government Catch
Kioxia Holdings and SanDisk said August 27 they plan to invest roughly ¥5tn — more than $31bn — in Japanese flash-memory production through 2032, extending a joint venture between the two companies that has already run for more than 25 years. The money is earmarked for two existing plants operated by Kioxia's namesake subsidiary, not new sites, and the investment plan carries an explicit condition: it depends on support from the Japanese government that neither company has detailed yet.
Why it matters: A ¥5tn commitment from two of the world's largest flash-memory makers is a bet that Japan stays central to global chip supply even as manufacturers weigh capacity elsewhere. It also extends Tokyo's semiconductor subsidy push, until now mostly associated with logic-chip projects, into the memory side of the industry.
The catch: Every yen of that figure is contingent on government support the companies have not specified — no number, no timeline, no mechanism. Until Tokyo puts a figure on the table, ¥5tn is an ambition, not a budget.
What to watch: Whether the Japanese government responds with a subsidy package before Kioxia and SanDisk need to commit capital, and how much of the ¥5tn ends up spent versus contingent on aid that may or may not arrive.

Boardroom and Buyout Battles

Luxshare's ¥795 Bid for Seed Leaves Its Largest Shareholder in Control
Luxshare Precision's Cayman-registered acquisition vehicle filed a tender offer on August 27 to take Seed Co. (TSE Standard: 7743) private at ¥795 a share, running from August 27 through October 13. Seed's board met the day before and voted to recommend that shareholders tender their stock.
The catch: Once the shares go private, Seed's largest shareholder — not Luxshare — ends up holding 51% of the voting rights, an unusual structure for a deal fronted by a major Chinese electronics manufacturer.

Kakaku.com Bidder Sweetens Offer by ¥1 as Rival's Grip on Key Shareholder Lapses
Kamgras 1 KK, the EQT-backed vehicle pursuing full ownership of Kakaku.com (TSE: 2371), raised its tender price by exactly one yen to ¥3,571 a share and pushed its deadline to September 10, stretching the offer window to 85 business days from 75 since it opened in May.
Why it matters: The one-yen bump is cosmetic. The real shift is that rival bidder BCPE Blitz Cayman's tender pact with Oasis Management, which holds 19.52% of Kakaku.com, expired August 20 after BCPE declined to match the higher price — freeing Oasis's stake to swing the outcome of a contested privatization.
SAAF Holdings Wins Poison Pill Vote by Excluding the Votes It's Aimed At
SAAF Holdings shareholders approved a warrant-based takeover defense by 71.54% at an August 25 extraordinary meeting. Every shareholder of record on the September 14 record date, except SAAF itself, will receive one stock acquisition warrant per share.
The catch: The company's independent committee stripped 63,044 votes tied to the shareholder group the defense is aimed at from the count before certifying the result — a procedural detail that decided how comfortable the margin looked.
Activist Investor Tells GungHo: Remove Representative Director or Chairman, or Find a Buyer
Strategic Capital, which holds 13.67% of GungHo Online Entertainment, told regulators it will demand the removal of either the company's representative director or its chairman if GungHo remains listed on the Tokyo Stock Exchange rather than delisting through a takeover.
Why it matters: It is an ultimatum framed as a routine large-shareholding filing — sell the company or lose its leadership — escalating an activist campaign against the Tokyo-listed game maker.

Earnings Upgrades and Capital Shuffles

Nippon Shokubai Raises Battery-Electrolyte Plant Budget to ¥43bn, Pushes Launch Back to December 2028
Nippon Shokubai raised the budget for its lithium-ion battery electrolyte (LiFSI) plant in Kitakyushu to about ¥43.0bn from roughly ¥37.5bn and pushed the commercial-operation date back to December 2028 from July 2028.
Why it matters: The company cites delayed land purchase and higher copper, petroleum and construction costs — concrete evidence that Japan's government-subsidized EV battery supply chain is running into real cost inflation, even as Tokyo's ¥12.5bn subsidy commitment for the project holds steady.

DyDo Lifts Profit Guidance Even as Its Turkey Inflation Forecast Jumps to 28.6%
DyDo Group Holdings lifted its full-year operating profit guidance by ¥1.8bn to ¥12.3bn and net profit guidance by ¥1.0bn to ¥6.0bn, even as it raised its year-end Turkish inflation forecast to 28.6% from 21%.
The catch: That inflation revision embeds a ¥1.1bn hyperinflation-accounting drag on operating profit, and the improved guidance still only marks a rebound from a ¥30.3bn net loss the year before.
Yamaha Books a ¥24.9bn Gain on Its Yamaha Motor Stake Sale, but IFRS Erases Most of It
Yamaha Corporation sold 14 million Yamaha Motor shares in a block trade on August 27, cutting its stake in the motorcycle and marine-engine maker to 1.46% from 2.84% and booking a ¥24.9bn standalone gain.
The catch: IFRS fair-value accounting keeps nearly all of that gain out of Yamaha's consolidated earnings — the stake sale is real, the profit boost mostly isn't.
SUMCO Cuts Its Stake in Taiwan Wafer Maker FST to 38%, Ending Consolidation
SUMCO finished selling down its stake in Taiwan's Formosa SUMCO Technology on the Taipei market on August 20, cutting its voting rights to 38.0% — below the threshold needed to keep the wafer maker inside SUMCO's consolidated accounts.
Why it matters: FST now moves to equity-method accounting from the end of September, changing how a chunk of SUMCO's exposure to Taiwan's chip supply chain shows up on its books; the earnings effect is still under review.
