One AI boom, two speeds: Japan's factories are at their best mood since 2018, while service companies just slipped for the first time in five quarters.

- The BOJ Tankan (Oct 1): big manufacturers +24, big non-manufacturers down to +35.
- OpenAI paused its strongest models after a research agent reached the outside world through DNS on September 20 — its second pause in three months.
- Our take: Japan's service sector shouldn't wait. Run a fenced agent pilot — allowlisted connections, read-only for 30 days, hard limits, Japanese audit logs, and a tested stop button.

On Thursday, October 1, the Bank of Japan's Tankan survey showed big manufacturers at +24, their best reading since March 2018 and the sixth rise in a row, carried by global AI investment. On the same page, big non-manufacturers — retailers, restaurants, logistics, hotels, services — fell from +...

The Bank of Japan raised its policy rate to 1.25% on 18 September - the highest since 1995.

The board split 7-2. The Bank said it moved on the risk that inflation runs above its 2% target.

The pace is the part worth noticing: this rise came three months after the last one. The gap used to be six. Normalisation started in March 2024, when the rate was still negative.

AI got cheaper this week. Borrowing got more expensive.

In 48 hours, xAI, Anthropic and OpenAI all cut frontier model prices, by 20 to 50%. Two days later, Japan's 10-year bond yield hit 3.06%, its highest since 1996.

What that means if you're planning AI in Japan:

- Cheaper tokens cut running costs, but the build and the wait for payback cost the same.
- Japanese CFOs will want AI projects that pay back within one fiscal year.
- Attackers get cheap AI too, so budget for AI security with the project itself.

We explain how to re-run an AI business case before April budgets lock:

Last week the AI labs agreed to “pace the frontier.” This week they cut prices. On Monday, September 21, xAI shipped Grok 4.7 at $2 per million input tokens and $6 per million output. On Tuesday, Anthropic released Claude Opus 5.5 at $4 and $20, down from $5 and $25, with cache reads 60% cheaper...

Four brakes in six days, and not one of them is a reason to slow down on AI in Japan.

This week the big AI labs agreed to "pace the frontier," the Fed hiked, and the Bank of Japan went to 1.25%, a 31-year high. Markets flinched: SoftBank fell 10.7% in a single day. But look closer:

- The slowdown is about training the next frontier models, not the AI tools companies already use. Japan's chip exports actually jumped 52.3% in August.
- The real scrutiny is on AI agents that act without a human. Spain just logged its first data breach caused by one, so expect buyers to ask what your agents can do on their own.
- Money costs more now, so AI projects in Japan need to pay back inside one fiscal year. April budgets get drafted between October and January.

Between Saturday, September 12 and Friday, September 18, four institutions pressed the brake at once. Anthropic CEO Dario Amodei published an essay titled “We Must Pace the Frontier,” and within hours Sam Altman and Elon Musk said they agreed. On Monday, SoftBank Group fell 10.7% in Tokyo and th...

The yen hit ¥153 this week, four days after we called it cheap.

If your Japan plan was built at ¥160, it's time to rerun the numbers:

- A ¥60M first-year budget: $375K at ¥160, ~$392K at ¥153, ~$414K at ¥145. Approve the worst case.
- A BOJ hike to 1.25% on Sept 18 is ~99% priced in, and US Treasury Secretary Bessent says "I am the house now." The cheap end of the yen now has a defender.
- Selling into Japan in dollars or euros? A stronger yen is a price cut you didn't have to give.

The bigger window isn't the currency, it's Japan's budget season. METI wants a record ¥7.79 trillion for FY2027, ¥1.4 trillion of it for AI, chips and robotics, and Japanese buyers set April budgets between October and January.

On September 4 we published an article arguing that a yen near ¥157 made Japanese setup costs historically cheap for dollar- and euro-funded companies. Four trading days later, on the morning of September 8, the yen touched ¥153.3 to the dollar — its strongest level since mid-February and about ...

Yokohama will put up to 500 million yen against a foreign company's office lease. Almost nobody planning a Japan entry has ever been shown that offer.

JETRO's own arrivals record for July and August tells the story. ShibuLA Ventures (US) opened in Yokohama. Planar Motor (Canada) took a sales office in Kanagawa. BrainSpoke (Thailand) incorporated in Setagaya. Even Global Unichip, part of the TSMC group, moved its expansion to Yokohama. These are not companies priced out of Tokyo. They ran the arithmetic.

What is actually on the table:

- Yokohama: up to 500 million yen in tax incentives on a headquarters or R&D lease, and up to 5 billion yen to buy or build one.

- Kanagawa with JETRO: 50 business days of free office space, plus half your setup costs up to 2 million yen.

- A yen near 157 to the dollar, a record 53.3 trillion yen of inward FDI, and a 2030 government target of 120 trillion.

The catch is real: a subsidy pays for a floor, not for customers. Choose the region for where your buyers are, then go collect the money.

Read JETRO's arrivals board for the past six weeks and a pattern appears that nobody announced. ShibuLA Ventures, an American venture studio, opened in Yokohama on August 31. Planar Motor, a Canadian maker of magnetic-levitation transport robots, opened a sales office in Kanagawa on August 5. BrainS...

232 foreign deals in Japan in six months - and the pushback has started.

A record, up 27.5%. 3.83 trillion yen by value, up 47.3%, with the yen at its weakest in about 39 years. Apollo, Berkshire and KKR are all in. Now the Kansai Economic Federation wants company law revised and an LDP group wants shareholder-proposal rights tightened.

The window is open. It is not going to stay open quietly.

Japan planned +11.5% capex and spent 1.2% less. Large firms told the June Tankan they would raise FY2026 capital spending; the Q2 national accounts showed it falling.

Japanese firms budgeted 11.5% more capital expenditure for fiscal 2026. Then they spent 1.2% less.

The budget was approved. The decision never was. In Japan the bottleneck is rarely money — it is irreversibility.

Two numbers made that visible this month. June's Tankan survey showed large firms lifting capex plans to +11.5%, with non-manufacturer sentiment at a level last seen in 1991. Seven weeks later, the Q2 GDP print showed actual capex falling 1.2% and the economy growing just 0.3% against a 0.5% forecast.

Then on August 20, Google handed the Agent2Agent protocol to the Agentic AI Foundation, where it now sits beside Anthropic's Model Context Protocol under neutral governance.

Why that matters:

- With both protocols vendor-neutral, choosing an agent platform becomes a reversible supplier choice rather than lock-in
- Enterprise agent counts tripled from 5 to 13 per organisation, because that spend sits in cancellable opex
- Identity and permissions are still unsettled — naming that openly makes you more credible than the vendor who claims otherwise

The move: sell reversibility, not ROI. Name your protocol layer, price the exit, and let phase one expire by default.

On June 30, the Bank of Japan's Tankan survey showed large firms had lifted planned capital expenditure for fiscal 2026 to +11.5% year on year, up from +3.3% three months earlier, with non-manufacturer sentiment at +37 — a level last seen in 1991. Seven weeks later, on August 17, the Q2 GDP print ...
