USD/JPY Trading Guide: Yen Pips, Safe-Haven Flows and the BoJ
USD/JPY trading explained: what a yen pip is worth, and how the US–Japan rate gap, safe-haven flows, the BoJ and intervention move the pair.
USD/JPY looks like any other major pair until you size your first trade and the pip value comes out as an odd number, or until a quiet morning turns into a 200-pip drop with no news on the calendar. USD/JPY trading has its own arithmetic and its own triggers, and both are worth learning before you place an order.
Quick answer: USD/JPY is the price of one US dollar in Japanese yen. A pip is the second decimal (0.01), worth ¥1,000 per standard lot, or about $6.67 at 150.00. The pair mainly follows the gap between US and Japanese interest rates, but the yen also rises in risk-off panics, and Japan’s Ministry of Finance occasionally intervenes.
What is USD/JPY? The dollar yen pair in plain English
USD/JPY is the exchange rate between the US dollar and the Japanese yen. Here the dollar is the base currency and the yen is the quote currency, so a price of 150.00 means one dollar buys 150 yen. When the price rises, the dollar is strengthening and the yen is weakening. When it falls, the yen is gaining ground. Traders call it “dollar yen”.
That direction trips up a lot of newcomers. If you think the yen will strengthen, the trade is to sell USD/JPY, because a stronger yen means one dollar buys fewer yen. It is the mirror image of EUR/USD, where the dollar sits on the right-hand side of the quote. Our lesson on currency pairs and quotes covers this in more detail.
USD/JPY is usually ranked as the second most traded currency pair in the world, behind EUR/USD, in the Bank for International Settlements’ three-yearly survey of global currency turnover. It is deep and liquid, and it is one of the few majors where a government occasionally steps into the market directly. We will come to that.
The other thing that sets the pair apart is how it is quoted. Because one yen is worth a fraction of a US cent, USD/JPY trades in the hundreds and is shown to two decimal places, not four. That moves the pip.
Yen pip value: why USD/JPY pips are worth less than $10
A pip on USD/JPY is 0.01. A move from 150.20 to 150.50 is 30 pips, and a move from 150.00 to 148.00 is 200 pips. Most platforms show one more digit, a third decimal, which is a pipette or one tenth of a pip.
Pip value is always counted in the quote currency first. On USD/JPY that is the yen, so the raw value is fixed in yen:
| Lot size | Dollars traded | Value of one pip in yen | In dollars at 150.00 |
|---|---|---|---|
| Standard lot | 100,000 | ¥1,000 | about $6.67 |
| Mini lot | 10,000 | ¥100 | about $0.67 |
| Micro lot | 1,000 | ¥10 | about $0.07 |
To turn the yen figure into dollars you divide by the USD/JPY price itself: ¥1,000 ÷ 150.00 = $6.67. So the dollar value of a yen pip changes as the pair moves, which never happens on EUR/USD. At 140.00 a standard-lot pip is worth about $7.14; at 160.00 it is worth $6.25. The higher USD/JPY goes, the less each pip is worth in dollars, because each yen buys fewer dollars.
The change is small day to day, but it is why you should recalculate rather than reuse an old figure. Type two prices into the counter below and watch the dollar value respond.
The highlighted digit is the pip. For USD/JPY the pip is the second decimal and its dollar value depends on the price.
If your account is in pounds or euros, there is one more step: the broker converts the yen result into your account currency at the going rate. The logic is the same; only the final number moves. Our guide to what a pip is in forex walks through every case, and the Academy lesson on pips and lots has practice questions.
Spreads on USD/JPY
The spread, the gap between the bid and the ask, is usually tight on USD/JPY during active hours. It widens around the daily rollover, in the thin hours before the Tokyo open, around major releases and, sharply, in the minutes after a suspected intervention. Our guide to forex trading costs explains how spread, commission and swap add up.
What moves USD/JPY: the US–Japan yield gap
Over weeks and months, the single most useful thing to watch for USD/JPY is the gap between US and Japanese interest rates. When US yields rise relative to Japanese yields, holding dollars pays more than holding yen, money tends to flow towards the dollar, and USD/JPY tends to rise. When the gap narrows, that support fades.
The mechanism is the same chain that links any central bank decision to a currency. Step through it below, then switch it to a cut.
How an interest-rate change reaches the exchange rate: policy rate, yields, capital flows, demand, price. For USD/JPY, the chain runs through both the Federal Reserve and the Bank of Japan, and what matters is the balance between them.
For USD/JPY, two sides of that chain matter, and for many years they were very unequal.
The Bank of Japan’s long era of ultra-low rates
The Bank of Japan (BoJ) kept its policy interest rate at or near zero for most of the period from the late 1990s onwards, as Japan struggled with weak growth and falling prices. In 2016 it went further, setting a small negative rate on some bank reserves and introducing yield curve control, a policy of buying government bonds to hold ten-year Japanese yields close to zero. For years, that made the yen the cheapest major currency in the world to borrow.
In March 2024 the BoJ ended its negative rate and yield curve control, its first rate rise in around seventeen years, and it has since raised rates in small, carefully signalled steps. Even so, Japanese rates have remained low by international standards. The direction of travel matters as much as the level: a BoJ that is expected to keep raising rates narrows the gap from the Japanese side, which tends to weigh on USD/JPY.
The BoJ holds eight policy meetings a year. Each lasts two days, and the decision is released on the second day with no fixed time, usually around midday in Tokyo, which is the early hours of the morning in the UK. The governor’s press conference follows in the afternoon, Tokyo time. Four times a year the BoJ also publishes its Outlook Report on growth and inflation, which often carries more information than the decision itself.
Why US Treasury yields matter so much
On the other side of the pair sits the US Federal Reserve, and the market’s best running gauge of where US rates are heading is the yield on US Treasury bonds. Many USD/JPY traders keep a chart of the two-year or ten-year Treasury yield open next to the pair, because over long stretches the two have tended to move together. The sketch below shows the shape of that relationship.
This is why US data often moves USD/JPY more than Japanese data does. A hot US inflation report or a strong jobs figure pushes Treasury yields up, because traders expect the Fed to keep rates higher for longer, and USD/JPY tends to follow. A weak report does the opposite. The surprise against the forecast is what counts, because the expected figure is already priced in. Our guide on how interest rates affect currency prices and the lesson on central banks and interest rates explain the full chain.
Japanese releases still matter, mostly through what they imply for the BoJ. Watch national and Tokyo inflation figures (Tokyo’s are published first and are treated as an early read), the BoJ’s quarterly Tankan business survey, and the outcome of the annual spring wage negotiations, known as shunto, which the BoJ watches closely when judging whether inflation will last.
Safe-haven yen and the carry trade
Rates explain the long trend. They do not explain the days when USD/JPY falls 150 pips while nothing is happening in Japan. For those, you need the yen’s other personality: a safe haven.
When investors feel confident, a mood often called risk-on, they buy stocks and higher-yielding currencies. When fear takes over, they sell those and buy safety. The yen, the Swiss franc and the US dollar are the traditional havens. Toggle the mood below to see how the major currencies tend to line up.
Tap a currency to see why it behaves this way.
Switch between risk-on and risk-off. The yen sits with the safe havens: it tends to strengthen when fear rises, which pushes USD/JPY and other yen pairs lower. These are tendencies, not rules.
The dollar is also a haven, yet in many risk-off episodes the yen has outperformed it, and USD/JPY has fallen. The main reason is the carry trade.
How the carry trade builds, and how it unwinds
A carry trade means borrowing in a low-interest currency and investing in a higher-interest one, pocketing the difference. With Japanese rates near zero for so long, the yen became the world’s favourite funding currency. Investors borrowed yen, sold it, and bought dollars, Australian dollars, emerging-market bonds or other higher-yielding assets.
In calm markets that is a slow, steady source of yen selling, which helps explain why USD/JPY can grind higher for months. The trouble comes when the mood breaks. A shock hits, the higher-yielding assets fall, losses mount, and investors close their positions. Closing means selling what they bought and buying back the yen they borrowed. When many investors do that at once, the yen can jump very quickly.
A clear recent example came in early August 2024. Shortly after the BoJ raised rates and a weak US jobs report pulled US yields lower, the yield gap narrowed from both sides at once. Yen-funded positions were closed in a rush, the yen rose sharply, and Japanese stocks suffered one of their largest one-day falls on record. Traders who had treated USD/JPY as a one-way bet learned how quickly a carry trade can unwind.
When stock markets are falling hard, assume that yen pairs will lean lower, and that crosses such as AUD/JPY, which pair a risk currency against the funding currency, may fall even faster than USD/JPY. Our full guide to risk-on vs risk-off and the Academy lesson on risk-on and risk-off show how to read the mood before you read the chart.
Energy is a quieter influence on the same side of the ledger. Japan imports nearly all of its energy, so a sustained rise in oil prices worsens its trade balance and tends to weigh on the yen, as the lesson on correlations explains.
USD/JPY and other pairs
Because the dollar is the base currency, USD/JPY often moves in the opposite direction to EUR/USD and GBP/USD on days dominated by US news, and in the same direction as USD/CHF. Tap the cells below to see how those relationships usually look.

How many times are you really betting on the dollar?
Illustrative long-run correlations between USD/JPY and other major pairs, not live data. USD/JPY tends to move with USD/CHF and against EUR/USD, but its links are looser than most because the yen has its own drivers.
The relationships are looser than they are between, say, EUR/USD and GBP/USD, because the yen has its own story. On a risk-off day, the yen can rally while EUR/USD also falls, so “sell USD/JPY” and “sell EUR/USD” can both work, or both fail, for different reasons. Count your dollar exposure before you stack trades; the lesson on correlation risk shows how.
Intervention: when Japan’s Ministry of Finance steps in
USD/JPY has one risk that most majors do not: direct government intervention. In Japan, the decision to intervene in the currency market belongs to the Ministry of Finance (MoF). The Bank of Japan carries out the trades on its behalf.
When the yen weakens quickly, Japanese officials have at times sold dollars from Japan’s foreign reserves and bought yen to slow the fall. They did so in 2022, the first yen-buying intervention in more than two decades, and again in 2024, both times after USD/JPY had climbed to levels not seen in decades. Officials usually say that they are concerned with the speed of moves and with speculation, rather than defending any particular level, and they rarely confirm intervention on the day. The ministry publishes intervention figures afterwards, which is often how the market finds out for certain.
Intervention tends to follow a recognisable pattern, sketched below.
The warning stage is worth learning to recognise. As the yen weakens, officials tend to escalate from routine comments about watching markets to stronger statements about excessive or speculative moves and readiness to act. None of this tells you when intervention will come, and sometimes it never does.
What it does tell you is that the risk of holding a long USD/JPY position has changed. An intervention can move the pair several hundred pips within minutes, spreads can widen sharply and stop orders can fill well away from their level, an effect called slippage. Three sensible responses when warnings are escalating:
- Size down. Use smaller positions so a sudden gap against you stays survivable.
- Respect your stop. Never hold a long USD/JPY position without a stop loss in this kind of market, and accept that it may slip.
- Do not treat intervention as a trade signal. On its own, intervention has tended to slow a move rather than reverse it, unless the interest-rate gap is turning at the same time. The fundamentals usually decide the direction.
When to trade USD/JPY: Tokyo, London and New York
USD/JPY is unusual among the majors in having a genuinely active Asian session. Japanese banks, exporters, importers and investors are all trading in Tokyo hours, so the pair moves in the morning in Asia when EUR/USD is often asleep. The clock below converts the main sessions into your local time.
Open now: …
The four forex sessions in your local time. USD/JPY is active in the Tokyo session, again around the London open, and most active in the London–New York overlap, when US data and Treasury markets dominate.
In UK time, a typical USD/JPY day looks like this:
- Tokyo session (roughly midnight to 09:00 in winter, an hour later in summer): Japan does not use daylight saving, so the UK-time hours shift twice a year. Most Japanese data is released shortly before or during this window, and BoJ decisions and official comments on the yen land in it too. Moves are often steadier than in London, but not always small.
- London open (around 07:00–09:00): volume rises as European desks arrive and the pair often tests the range set in Tokyo.
- London–New York overlap (about 13:00–17:00): usually the most active stretch. US data comes out at 13:30 UK time for most of the year, Treasury markets are fully open, and the yield story is in charge.
- Late New York: activity fades, though Federal Reserve decisions at 19:00 UK time can move the pair sharply.
Two Tokyo quirks are worth knowing. Banks in Japan set a reference rate known as the Tokyo fix at 9:55 a.m. Tokyo time, and there can be extra flow around it. On gotobi days, dates ending in a 5 or a 0, many Japanese companies settle payments, and market lore says importers’ dollar buying can lift USD/JPY ahead of the fix. Treat that as background colour, not a strategy: the effect, if any, is small and unreliable.
Our guide to forex market hours and the lesson on market sessions cover time zones and daylight saving in full. And if you also trade the euro, compare this rhythm with the one in our EUR/USD trading guide, which is much quieter in Asian hours.

Because a yen pip is worth less than $10 in dollars, the “divide by ten” shortcut that works on EUR/USD gives the wrong position size on USD/JPY. Here is the full calculation.
In step 5, because the yen result is converted at the closing price, the dollar figure drifts slightly from plan. Our guide to position sizing in forex and the lesson on position sizing cover the method for every type of pair.
Common mistakes when trading USD/JPY
Using the EUR/USD pip value
Assuming a standard lot is worth $10 per pip on USD/JPY means your real risk is about a third smaller than you planned at 150.00, because the true figure is about $6.67. That sounds harmless, but it means your 1% is no longer 1%, and the habit causes real damage when it is carried the other way, for example by reusing a yen-pair figure on a pair where the pip is worth more. Recalculate from ¥1,000 ÷ price every time.
Getting the direction backwards
A strong yen means a falling USD/JPY. Traders who are bullish on the yen sometimes buy the pair by reflex. Say the trade out loud before you place it: “I am buying dollars and selling yen.”
Ignoring the risk mood
A long USD/JPY position is partly a bet that markets stay calm. When stocks are falling hard and carry trades are being unwound, the chart setup that looked fine yesterday may no longer matter. Check the mood before the setup.
Treating the trend as a one-way street
Long periods of yen weakness tempt people to buy every dip with ever larger size. That is exactly the crowded positioning that makes unwinds and interventions so violent. Keep your risk per trade fixed, however strong the trend looks.
Fighting an intervention or chasing it
Selling into a rising USD/JPY because “intervention must be close” is guessing. So is jumping in after an intervention spike. Neither is a plan. Reduce size when warnings escalate, and let your normal setup, not the headline, decide your entries.
Frequently asked questions
How much is 1 pip worth on USD/JPY?
One pip on USD/JPY is 0.01 and is worth ¥1,000 on a standard lot of 100,000 dollars, ¥100 on a mini lot and ¥10 on a micro lot. In dollars, divide by the price: at 150.00 a standard-lot pip is worth about $6.67. The dollar value falls slightly as USD/JPY rises and rises as it falls.
Why is the yen a safe haven?
Mainly because of the carry trade. For years Japanese rates were near zero, so investors borrowed yen to buy higher-yielding assets. When fear rises, those positions are closed and the borrowed yen is bought back, which lifts the yen. Japan's large holdings of foreign assets add to the effect when money is brought home.
What moves USD/JPY the most?
Over time, the gap between US and Japanese interest rates, often tracked through US Treasury yields, is the main driver. Day to day, surprises in US jobs and inflation data, Fed and Bank of Japan decisions, shifts in global risk mood and the threat of intervention by Japan's Ministry of Finance cause the largest moves.
When is the best time to trade USD/JPY?
There is no best time for everyone, but the pair is active in three windows: the Tokyo session, the London open and especially the London–New York overlap, roughly 13:00 to 17:00 UK time. Choose the active hours you can actually be present for, and check the calendar for US data and BoJ meetings first.
What happens when Japan intervenes in the yen?
Japan's Ministry of Finance instructs the Bank of Japan to sell dollars and buy yen, usually after a fast fall in the yen and a run of verbal warnings. USD/JPY can drop several hundred pips within minutes and spreads can widen. Whether the move lasts has tended to depend on the interest-rate gap: if it still favours the dollar, the pair can drift back.
Is USD/JPY good for beginners?
It can be. It is liquid, usually cheap to trade and active in Asian hours as well as European and US hours. But beginners need to learn the different pip value, the reversed direction compared with EUR/USD, and the risk of sudden moves from carry-trade unwinds or intervention before trading it with real money.
