US Central Command said American forces have now redirected 55 commercial vessels away from Iranian ports as of Sunday, up from 35 as of August 2, with two ships disabled and two boarded to enforce compliance, according to CNBC. Iran has set out sweeping demands to reopen the strait — lifting the blockade and sanctions, withdrawing US troops, war reparations, and releasing frozen assets — none of which Washington shows signs of meeting. Oil stayed choppy on the standoff, and for Japan, which imports the overwhelming majority of its crude through this same waterway, every extra week of blockade is a direct hit to import costs layered on top of an already-weak yen.

Fed Chair Kevin Warsh has now gone two straight meetings without offering forward guidance, an unusual degree of silence that's leaving traders to price policy moves blind rather than off any signaled path, a dynamic flagged by the Motley Fool. Paired with the BOJ's own hawkish drift today, the widening gap between an opaque Fed and an increasingly vocal BOJ board is exactly the kind of setup that moves USD/JPY hard in either direction once one side actually commits.

China's July consumer prices rose just 0.5% year-on-year, down from June's 1.0% and a six-month low, while producer prices fell 3.5% — still deeply negative but narrower than June's 4.1% drop — with weak transportation-fuel costs, soft food and rent prices, and persistent overcapacity all cited as drags, according to Investing.com. Continued Chinese demand weakness is a headwind for Japanese exporters even as Tokyo's own market rallies on other themes today.

Berkshire Hathaway posted $25.7 billion in second-quarter net income, powered by $10.9 billion in investment gains, with operating earnings up to $12.98 billion from $11.16 billion a year earlier, according to CNBC. CEO Greg Abel — who took over from Warren Buffett at the start of the year, with Buffett remaining chairman — turned the company into a net buyer of equities for the quarter with nearly $20 billion in purchases, including a $10 billion stake in Alphabet, alongside $4.5 billion in share buybacks. It's the same AI-and-Big-Tech trade that's driving today's Tokyo rally, now with the world's most-watched capital allocator visibly leaning into it.

SK Hynix and Samsung both slipped Monday even as the wider Korean and Japanese markets rallied, after their own results showed DRAM and NAND pricing growth decelerating from the blistering pace of recent quarters — a signal the Motley Fool says should worry Micron investors specifically, since Micron's own coming results will be judged against the same slowing pricing trend. More on what this means for Japan's own chip-equipment names in Tech, below.

Typhoon Dolphin has prompted more than a million evacuations in China and grounded roughly 40% of flights out of Shanghai as record rainfall hit the city, according to the Guardian. The same storm system already brushed Japan's south over the weekend; a second, separate system — Typhoon No. 15 — is now the one to watch for a possible Tohoku landfall as soon as Tuesday.

The Philadelphia Semiconductor Index fell 21% in July — its worst monthly performance since 2008 — as doubts over the sustainability of AI spending triggered sharp swings, with Asia-focused stock-picking hedge funds losing 15.2% for the month, their worst on record, according to Hedgeweek. AI-focused fund Situational Awareness reportedly lost 67% in July, shrinking from roughly $45 billion in assets to around $10 billion. That same embattled fund is now making a fresh bet: a $400 million investment in chip startup Source Foundry, according to TechCrunch. Today's AI-buying-driven Nikkei rally is the mirror image of exactly the volatility that just gutted these funds — a reminder that the same trade cuts both ways, fast, in both Tokyo and New York.

Samsung and SK Hynix both posted DRAM pricing gains this past quarter — SK Hynix around 30% sequentially, Samsung above 40% — with NAND climbing even faster, but analysts now expect pricing gains to slow to roughly 19% for the current quarter, well short of the near-50% some had modeled, according to Yahoo Finance. That's the clearest signal yet that the AI-driven memory shortage may be starting to ease. For Japan, it's a direct read on demand at Advantest and Tokyo Electron, both leveraged to the same memory-equipment cycle that's now showing its first signs of cooling.

Beyond the headline investment figure covered in Japan Markets, Sony and TSMC's Kumamoto venture is explicitly framed around image sensors for robotics and autonomous vehicles — not just smartphone cameras — positioning both companies for the next leg of AI moving off screens and into physical machines, according to Sony Semiconductor Solutions' own announcement confirming the May framework the two sides are now finalizing.

Apple has been testing memory chips from China's CXMT for potential use in future products, but any move to custom silicon would require sharing technical specifications that current US tech-transfer rules block, according to the Wall Street Journal via Techmeme. It's a live test of how far Washington's chip-technology restrictions reach into ordinary commercial sourcing decisions, not just cutting-edge AI accelerators.

Chinese AI labs account for nine of the top ten models on Artificial Analysis' text-to-video leaderboard, a sign of both fast domestic progress and growing global adoption that could hand Chinese developers an edge in building broader "world models," according to Bloomberg via Techmeme. It's a competitive data point worth watching against Japan's own, comparatively modest, AI-model ambitions.

More than 500 US towns and counties have now passed restrictions or outright bans on new data centers, up from over 300 in late June, following statewide restrictions added in New York and Texas, according to The Information via Techmeme. The contrast with Japan's own aggressive data-center and power buildout — actively courted by prefectural governments — is notable as AI infrastructure siting becomes a genuine political fight in the US.

Japan's dominant mobile-payment app PayPay has passed 75 million registered users, now accounting for more than 20% of all cashless payment transactions nationwide, according to Livedoor News. It's a milestone that underscores just how completely the app has displaced cash for everyday purchases across the country in under a decade.

"Spider-Man: Brand New Day" is closing in on $2 billion globally in its second weekend, and has become the highest-grossing Hollywood film ever released in India, according to Variety. It's also holding the No. 1 spot at the Chinese box office even as Christopher Nolan's "The Odyssey" surges in previews there.

Christopher Nolan's "The Odyssey" has passed "The Dark Knight Rises" to become the highest-grossing film of his career, according to Polygon. The film is also currently beating "Spider-Man: Brand New Day" at the South Korean box office in a genuine head-to-head between two of the year's biggest global releases.

HBO's "House of the Dragon" closed out its third season with a finale that's drawn heavy discussion for its parallels to the original "Game of Thrones" endgame, with showrunner Ryan Condal telling Variety the Rhaenyra-Daenerys echoes are intentional rather than coincidental. A fourth season is already in the works.

Idol group WEST.'s Shigeoka and Hamada announced their marriages on the same day, pushing the group's married-member count past half its lineup, according to Livedoor News — enough of a milestone that fans online have been joking they can no longer keep track.

Nintendo will repair Switch and Switch 2 consoles and accessories damaged in last month's Kumamoto earthquake at no cost, regardless of warranty status, for anyone in the government's designated disaster-relief zones, with the offer open through February 1, 2027, according to Kotaku. The company has also committed ¥50 million to the Japanese Red Cross Society for broader relief efforts. It's a small gesture next to the scale of the disaster, but a genuinely warm one — the kind of quiet corporate goodwill that doesn't ask for anything back.
