Understanding JPY Pairs and
Decimal Differences in Trading

Japanese yen, or JPY, currency pairs can look different from other forex pairs. This is mainly because they use a different decimal format.

For example, EUR/USD may appear as:

However, USD/JPY may appear as:

Both are forex quotes. Both show the relationship between two currencies. The main difference is the number of decimal places shown after the price.

This can be confusing at first. A beginner may see USD/JPY at 156.200 and wonder why the number is much larger than EUR/USD at 1.08450. They may also wonder why a one-pip movement is read differently in JPY pairs.

The answer is simple. JPY pairs use a different quote format. Once you understand where the pip appears, JPY prices become much easier to read.

What is a JPY Pair?

A JPY pair is any forex pair that includes the Japanese yen.

Some common examples are:

In each example, JPY is the second currency. This means the quote shows how many Japanese yen are linked to one unit of the first currency.

For example, if USD/JPY is quoted at 156.20, it means one US dollar is quoted at 156.20 Japanese yen.

If EUR/JPY is quoted at 169.50, it means one euro is quoted at 169.50 Japanese yen.

The first currency is always the currency being quoted. The second currency is used to show its value.

Why Do JPY Prices Look Different?

Most forex pairs, such as EUR/USD or GBP/USD, are traditionally shown with four decimal places.

For example:

In this type of quote, one pip is usually the fourth digit after the decimal point.

A move from 1.0845 to 1.0846 is one pip.

JPY pairs are different. They are traditionally shown with two decimal places.

For example:

In this type of quote, one pip is usually the second digit after the decimal point.

A move from 156.20 to 156.21 is one pip.

This does not mean JPY pairs are more difficult. It simply means you need to look at a different decimal position when reading the quote.

Reading a USD/JPY Quote

Let’s look at a simple USD/JPY example.

This can be read as:

One US dollar is quoted at 156.20 Japanese yen.

Now imagine the price changes to:

The second digit after the decimal point has changed from 0 to 1.

This is a one-pip movement.

If the price changes from:

to

the pair has moved by five pips.

If the price changes from:

to

the pair has moved lower by five pips.

Pips only measure the size of the movement. They do not tell you whether the move is positive or negative, and they do not predict where the market may move next.

The Main Decimal Difference

The easiest way to understand the difference is to compare EUR/USD with USD/JPY.

For EUR/USD:

The pip is in the fourth decimal place.

For USD/JPY:

The pip is in the second decimal place.

This is the key rule to remember.

For many pairs that do not include JPY, such as EUR/USD, GBP/USD and AUD/USD, one pip is usually 0.0001.

For many pairs that include JPY, such as USD/JPY, EUR/JPY and GBP/JPY, one pip is usually 0.01.

You do not need to memorize a complicated formula. Just remember that JPY pairs use two decimal places for a full pip instead of four.

Why Do Some Platforms Show Three Decimal Places?

Many trading platforms show an extra decimal place for more detailed pricing.

For example, instead of showing:

the platform may show:

The extra final digit is smaller than one full pip.

In this example, the second decimal place is still the full pip position. The third decimal place shows a fraction of one pip.

Look at this movement:

This is a very small movement. It is commonly described as one fractional pip, pipette or point, depending on the platform.

Now look at this movement:

This is one full pip.

A simple way to remember this is that, on many three-decimal JPY quotes, 10 points commonly equal one pip.

However, platforms may use different terms. It is always important to check the product specification or platform guide for the exact definition used by the provider.

Reading EUR/JPY and GBP/JPY

The same decimal rule applies to other JPY pairs.

Imagine EUR/JPY is quoted at:

This means one euro is quoted at 169.50 Japanese yen.

If the price moves to:

the pair has moved by one pip.

If it moves to:

the pair has moved by 10 pips.

Now look at GBP/JPY:

If the quote changes to:

the pair has moved by five pips.

The rule stays the same. For JPY pairs, focus on the second digit after the decimal point when reading full pips.

Understanding JPY Price Movements

A price movement means that the exchange-rate relationship between the two currencies has changed.

For example, if USD/JPY moves from 156.20 to 156.35, the US dollar is now quoted at a higher number of Japanese yen than before.

If USD/JPY moves from 156.20 to 156.05, the US dollar is now quoted at a lower number of Japanese yen than before.

The quote does not explain why the price moved. It only shows that the relationship between the two currencies has changed.

Currency prices can move during market hours because of many factors. These may include economic data, interest-rate decisions, central-bank statements, political developments and wider market activity.

Market information does not provide certainty about future movements. JPY pairs, like all forex pairs, can move in either direction.

JPY Pairs and Buy-Sell Quotes

Forex platforms usually show two prices for a currency pair.

For example:

The first price is commonly the sell-side price. The second price is commonly the buy-side price.

The difference between these two prices is called the spread.

In this example, the difference is 0.005. On a three-decimal JPY quote, this is commonly five points, or half a pip.

Now consider this quote:

The difference is 0.010. This is commonly one pip.

Understanding the decimal format helps make the spread easier to read. Always check whether your platform uses two decimal places or three decimal places for JPY pairs.

Common Mistakes When Reading JPY Pairs

One common mistake is reading the final digit in a three-decimal JPY quote as a full pip.

For example, a movement from 156.200 to 156.201 is usually not one full pip. It is one fractional-pip movement.

Another common mistake is using the EUR/USD decimal rule for USD/JPY.

EUR/USD usually uses the fourth decimal place for one pip. USD/JPY usually uses the second decimal place for one pip.

A final mistake is comparing a two-decimal quote with a three-decimal quote without checking the format first.

For example, USD/JPY at 156.20 and USD/JPY at 156.200 show the same price level. The second quote simply includes an extra digit for more detailed pricing.

A Simple Way to Read Every JPY Pair

When you see a JPY pair, first identify the pair name.

For example, USD/JPY means US dollar against Japanese yen.

Then look at the decimals.

If the quote is shown with two decimal places, the second decimal place is usually the pip position.

If the quote is shown with three decimal places, the second decimal place is still usually the pip position. The third decimal place is normally a smaller fraction of one pip.

Finally, compare the earlier quote with the later quote.

The pair moved by four pips.

This simple method works for USD/JPY, EUR/JPY, GBP/JPY and many other JPY pairs.
