Four Days After We Called the Yen Cheap, It Hit ¥153: A 99%-Priced BOJ Hike, Bessent's “I Am the House,” and How to Reprice a Japan Plan Built at ¥160

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 7% stronger than the four-decade low near ¥164 it hit in July. That same week, US Treasury Secretary Scott Bessent told an audience in Texas “I am the house now,” saying that when Washington intervenes on the yen he has good insight into what the Bank of Japan will do. Rate futures price a hike from 1.0% to 1.25% at the BOJ's September 17–18 meeting at roughly 99%, and a Reuters poll sees 1.75% by mid-2027. Real wages have risen for seven straight months, producer prices are up 7.6%, and METI has requested a record ¥7.79 trillion for fiscal 2027, with ¥1.4 trillion aimed at AI, semiconductors and robotics. None of this means the yen will keep rising — it slipped back to about ¥154 by September 11. It means the cheap end of the range now has a named defender, while the expensive end is open. Here is how to reprice a Japan plan built at ¥160, why the stronger yen is quietly good news for anyone selling into Japan, and why the window that matters now is not the currency window but Japan's budget season.

The Cheapest Door Into Japan Isn't in Tokyo: Yokohama Will Put Up to ¥500 Million Against a Foreign Company's Office — and This Summer's Arrivals Are Walking Through It

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. BrainSpoke, a Thai wearables company, incorporated in Setagaya on July 30. Global Unichip Japan, part of the TSMC group, moved its expanding operation to Yokohama. These are not companies that failed to get into Tokyo. They are companies that ran the arithmetic. Yokohama will offer a foreign firm up to ¥500 million in tax incentives against the lease of a headquarters or R&D base, and up to ¥5 billion toward purchasing or building one; Kanagawa gives 50 business days of free office space and covers half of setup costs up to ¥2 million. Meanwhile the yen sits near ¥157 to the dollar, Japan's inward FDI stock hit a record ¥53.3 trillion, and the government has raised its 2030 target to ¥120 trillion. The subsidy is real, the timing is unusually good, and the catch is real too — a grant pays for a floor, not for customers. Here is what is actually on offer, what it does not buy, and how to decide whether your Japan entry should land outside the capital.

The Plan and the Print: Japanese Firms Budgeted 11.5% More Capex, Then Spent 1.2% Less — and a Quiet Standards Handover Explains How to Close the Gap

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 showed actual capital expenditure falling 1.2% quarter on quarter, private consumption flat, and the economy growing just 0.3% against a forecast of 0.5%. The budget was approved. The spending never happened. That gap is not a forecasting error — it is the shape of how Japanese companies handle decisions they cannot undo. And on August 20, in a piece of news that read like plumbing, Google handed the Agent2Agent protocol to the Agentic AI Foundation, where it now sits beside Anthropic's Model Context Protocol under neutral governance. Nothing got faster that day. What changed is what happens to a buyer who wants to leave — which is precisely the risk that has been holding those approved yen in place. Here is what the two numbers mean, why irreversibility rather than budget is the real bottleneck in Japan, and how to restructure a proposal so the money moves before the fiscal year closes in March.

The Quiet Landings: Four Mid-Size Design, Food and Tech Companies Broke Into Japan This Year — and Not One of Them Started With a Flagship

Japan's inbound investment stock hit a record 53.3 trillion yen and 61.6% of foreign-affiliated companies expect a profit this year — but the names in the headlines are always the giants. The interesting entries of 2026 were made by companies you have not heard of: an Italian bag maker with 200 stockists, an American designer with eight Japanese wholesale accounts, a burger chain on its second attempt, and a French laboratory with no sales team. None of them entered the way the guidebooks say you should.

The Floor Rose, the Door Is Closing: Japan Lifted the Wage Floor 4.9%, Bankruptcies Topped 1,000 for Two Straight Months, and the Simplest Way to Buy Into Japan Expires in 2027

On August 11, 2026, Tokyo Shoko Research reported something Japan had not seen in fourteen years: two consecutive months with more than 1,000 corporate bankruptcies. June alone brought 1,021 failures, up 20.4% year on year, and the first half closed above 5,300 — the worst in twelve years. Two weeks earlier, on July 28, the Central Minimum Wages Council set the fiscal 2026 guideline at plus ¥55, a 4.9% rise that takes the national average to ¥1,176 an hour and Tokyo to roughly ¥1,280 from October. Read as separate headlines, one is a labour story and one is a distress story. Read together, they are a single sentence: the cost floor under Japanese labour is now rising faster than small firms can pass it into their prices. That is not a crisis for foreign companies operating here — it is a repricing, and it cuts both ways. The suppliers, subcontractors and distributors you depend on are the ones failing. The same firms, half of which have no successor at all, are also the cheapest acquisition targets Japan has offered in a decade. And the route most foreign buyers use to acquire them — buying the offshore holding company rather than the Japanese entity — was written out of the rulebook when the amended Foreign Exchange and Foreign Trade Act was promulgated on June 5, with implementing regulations consulted on until August 2 and most provisions landing by mid-2027. Three clocks, one desk.
