When traders talk about Japan’s business mood, they usually mean the Tankan. It is the Bank of Japan’s quarterly survey of companies, and the headline manufacturers’ index is one of the country’s most watched economic figures. A related monthly poll, the Reuters Tankan, often gives markets an earlier steer. Together they help shape views on the yen, Japanese shares and the Bank of Japan’s next move.
What the official Tankan is
The Tankan is a short-term economic survey run by the Bank of Japan, covering thousands of firms from large manufacturers to smaller non-manufacturers. Companies are asked about business conditions, supply and demand, employment, prices and their plans for investment and output. The best-known number is a diffusion index: the share of firms that say conditions are good minus the share that say they are bad.
A positive reading means optimists outweigh pessimists. Markets focus especially on large manufacturers, because that series has a long history and is closely tied to exports and global demand. The survey also publishes firms’ forecasts for the next quarter, which can matter as much as the current reading.
How the Reuters Tankan fits in
The Reuters Tankan is a separate, unofficial monthly survey of Japanese manufacturers. It is not a substitute for the Bank of Japan’s quarterly report, but it is often treated as a preview because it arrives more frequently and can hint at whether official sentiment is improving or fading between the big releases.
A strong Reuters Tankan can support the idea that the official index will hold up; a weak one can plant doubt early. The usual caveat applies: a private monthly poll has a different sample and can diverge from the official result. Traders use it as a temperature check, not as a final verdict.
Why the yen and shares care
A firmer Tankan, especially among large manufacturers, can strengthen the case that Japan’s economy can tolerate less ultra-easy policy. That can support the yen and Japanese bank shares, and it can complicate the long-running yen carry trade. A slump in sentiment can do the opposite, particularly if it points to weaker capital spending or export demand.
The Bank of Japan also uses the survey in its own assessment of the economy, which is why the report can move expectations even when it is not a policy meeting day. Our guide to the BoJ Summary of Opinions is another window on how the board is thinking between decisions.
How to read it without overreacting
Look at more than the headline manufacturers’ number. Non-manufacturers, employment, output prices and investment plans often tell you whether strength is narrowly export-led or broader. Compare the outcome with firms’ own forecast from the previous survey, not just with a market consensus. A beat that is weaker than companies themselves expected can be less encouraging than it first looks.
And remember that Japan is an open economy. A shiny Tankan can fade quickly if global demand, the yen or US yields change the outlook for exporters.
A UK trader’s reading order
If you have only a few minutes with the release, start with the large manufacturers’ index versus both the consensus and the previous forecast, then look at non-manufacturers, output prices and capital-spending plans. That sequence tells you whether the story is a narrow export bounce or a broader improvement in domestic conditions, which is more relevant for the Bank of Japan’s policy debate.
The yen reaction can be messy on the day, because US yields and the wider risk mood often dominate the dollar-yen rate. A firm Tankan does not guarantee a stronger yen if US interest rates are still rising. The survey is still worth filing, because it accumulates: a run of strong readings is harder for the Bank of Japan to ignore than a single monthly Reuters preview.
The bottom line
The Tankan is the Bank of Japan’s flagship business survey, with the Reuters Tankan offering a monthly unofficial preview. The manufacturers’ diffusion index is the figure markets quote, but the detail on prices, hiring and investment is what helps traders judge the policy implications.
