Bridgestone's Japan segment earned ¥171.6 billion of adjusted operating profit in January-September 2026, ¥13.4 billion more than its Americas segment, on revenue equal to 55% of the Americas' ¥1,753.4 billion. The figures come from the company's third-quarter results, published on 12 November 2026, four days after a fire hit the curing area of its Tosu tire plant in Saga prefecture on the evening of 8 November.
Japan's lead is the widest in five years of comparable data. Its margin rose to 17.8% from 14.4% a year earlier, while the Americas slipped to 9.0% from 10.0% even as its revenue grew 11%. Group revenue rose 10% to ¥3,554.3 billion and adjusted operating profit rose 21% to ¥445.3 billion, a record for the period. For anyone who buys from, sells against or invests in Bridgestone, the profit engine has moved from Nashville toward Tokyo, and the reasons are a weak yen, a domestic price increase and a tariff bill in the United States.
Japan's profit rose 87.5% in four years while the Americas fell 16.0%
In January-September 2022, on the segment basis Bridgestone adopted in 2023, the Americas earned ¥188.4 billion and Japan ¥91.5 billion. The Americas was 2.06 times as profitable. Four years later the order has reversed: Japan earned ¥171.6 billion and the Americas ¥158.2 billion. Japan's adjusted operating profit rose 87.5% over the period, while the Americas fell 16.0%, even though Americas revenue grew faster (21.9% against 17.7% for Japan).
This is the second time in three years that Japan has out-earned the Americas over the first nine months. In 2024 the margin was thin, ¥135.6 billion against ¥130.7 billion, and the Americas recovered to ¥157.8 billion in 2025. The 2026 gap is wider and comes with a much higher Japan margin.

One definitional point matters. Since fiscal 2023, Bridgestone books the profit on tires exported from Japan in the Japan segment rather than in inter-segment eliminations. That makes Japan partly an export business, so a weaker yen flows straight into its margin. The dollar averaged ¥159 in January-September 2026 against ¥148 a year earlier, and currency added ¥44.0 billion to group profit. The Japan figure is therefore a measure of what Japanese factories earn, at home and abroad, not only of the Japanese replacement market.
The margin gap reached 8.8 points, the widest of the five periods since 2022
Japan's margin held between 17.4% and 18.2% in each quarter of 2026. The Americas swung from 7.1% in the first quarter to 10.8% in the second and back to 8.9% in the third. Over the nine months the gap was 8.8 percentage points, against 4.5 points in 2025 and 7.5 points in 2024. In 2022 the Americas margin was 2.0 points higher than Japan's.
Part of the 2026 Americas decline is an accounting move. From the third quarter, Bridgestone changed its intercompany royalty rates, which cut Americas profit by about ¥8.6 billion and EMEA profit by about ¥5.7 billion, with the offset booked in corporate items and no effect on the group total. Adding the ¥8.6 billion back gives the Americas about ¥166.8 billion, still ¥4.8 billion below Japan. The reversal survives the adjustment.
The full-year segment targets, set in February and not updated on 12 November, still assume the Americas ends the year ahead: ¥221.0 billion against ¥200.0 billion for Japan. After nine months Japan has booked 85.8% of its target and the Americas 71.6%. Either Japan's fourth quarter falls sharply, as the pre-buy unwinds, or the February segment split is out of date.
A 5% price increase pulled Japanese replacement demand into the third quarter
On 15 June 2026, Bridgestone announced an average 5% increase in Japanese replacement tire prices, covering summer and winter tires, tubes and flaps, effective 1 September. The company cited raw material, logistics, labor and energy costs. Dealers bought ahead. Bridgestone's passenger and light truck replacement sales in Japan rose 22% in units in the third quarter, against market growth of 5%, after gains of 3% and 7% in the first two quarters. Over nine months its sales rose 11% while the market grew 3%.
Bridgestone itself attributes the third-quarter jump to "pre-buy demand ahead of price increases". That volume was pulled forward, not created. Dealers that stocked up in the third quarter are likely to order less in the fourth quarter, which is also when Bridgestone expects higher raw material costs to bite harder. The Japan margin of 17.4% in the third quarter, down from 18.2% in the second, may already show the price-cost squeeze beginning.
The Tosu fire adds a supply question to the domestic picture. The blaze started at about 7:30 pm on 8 November in the curing process, was put out at 11:19 pm, and all 148 people in the plant were evacuated without injury, according to Bridgestone's 9 November statement. The company announced a restart of production on 12 November and said the effect on full-year guidance is expected to be limited while the financial impact is assessed. Japanese plants produced 340,000 tonnes of rubber in tires over the nine months, against 370,000 tonnes in the Americas.
US tariffs cost ¥31.0 billion and raw materials turned against Bridgestone in the third quarter
Bridgestone's profit bridge for the nine months attributes ¥31.0 billion of cost to US tariffs: ¥7.0 billion within raw materials and ¥24.0 billion within other items. Set against the Americas' ¥158.2 billion of profit, that is equal to 19.6%. The company does not split the tariff cost by segment, but US import tariffs are most likely to fall on the US side of the business, which would help explain why Americas revenue rose 11% while profit was flat.
Raw materials, net of cost reduction, were neutral over nine months but changed direction within the year. They added ¥23.0 billion in the first half and subtracted ¥23.0 billion in the third quarter alone. Bridgestone said the impact of higher raw material costs became "more pronounced" in the third quarter and expects a greater effect in the fourth. That is why it raised full-year revenue guidance to ¥4,700 billion from ¥4,500 billion but kept its profit guidance unchanged, despite what it called potential upside on progress to date.
Operations in the Americas are not weak on volume. In North America, Bridgestone's passenger and light truck replacement sales fell 2% over nine months against a market down 3% (down 5% on the USTMA and TRAC measure). Truck and bus original equipment sales jumped 68% in the third quarter against market growth of 25%. The problem is cost and price, not share.
Elsewhere in the group, the specialties business, which includes ultra-large mining tires, lifted its margin to 24.4% from 20.6%, and EMEA improved to 6.7% from 5.3%. Passenger and light truck tires overall earned 11.7%, and truck and bus tires 9.5%.
Five ways buyers and investors should read the shift
Tire makers. A rival with a 17.8% home-market margin, partly earned on exports priced in dollars and euros, can fund price competition abroad if the yen stays near ¥159. Competitors in North American replacement should expect Bridgestone to defend share with product and brand spending rather than cede volume, as its nine-month sales already beat the market.
Distributors and dealers in Japan. The third-quarter pre-buy means inventory in the channel is higher than usual entering winter. Expect slower sell-in from manufacturers in October-December and watch for promotional activity once winter tire season ends. For a market view, see our Japan tire market report.
Raw-material buyers. A swing from a ¥23.0 billion tailwind to a ¥23.0 billion headwind inside one quarter shows how fast rubber and chemical costs are moving through Bridgestone's contracts. Suppliers negotiating 2027 terms will meet a buyer that has already absorbed a quarter of higher costs and is guiding for more.
OEMs. Bridgestone's truck and bus OE sales in North America rose 68% in the third quarter as demand recovered, and Japanese passenger and light truck OE sales rose 5% in the third quarter. A plant fire in Japan and tariff costs in the United States both argue for OEM purchasing teams to confirm dual sourcing for fitments that rely on Japanese production. Demand context is in our North America passenger car tires market report.
Investors. The group margin of 12.5% now depends heavily on a Japan segment that is exposed to the yen and on specialties, where strong sales of ultra-large mining tires helped lift the margin to 24.4%; our mining tires market report covers that segment. A stronger yen, a fourth-quarter hangover from the pre-buy and rising raw material costs would all hit the same segment at once. The Americas, at 9.0%, likely carries most of the tariff exposure and the most room for margin recovery if trade costs ease.
Methodology and sources
All segment figures are adjusted operating profit and revenue for January-September, in billions of yen, as reported by Bridgestone. The 2022 figures use the restatement published in Bridgestone's fiscal 2023 third-quarter presentation, which moved Japan's export business into the Japan segment, so the five years are on a consistent basis. Percentage changes and the margin gap were computed from the reported figures. Margins are as reported. The ¥166.8 billion royalty-adjusted Americas figure adds back the ¥8.6 billion that Bridgestone disclosed. Tariff costs are the sum of the two items labelled as US tariff cost impact in the company's profit bridge.
