What Is the Difference Between 「に応じて」 and 「に合わせて」? Understanding Formal JLPT N2 Expressions

「に応じて」 and 「に合わせて」 both mean “to change according to something”

In JLPT N2 grammar, learners often confuse 「に応じて」 and 「に合わせて」.

Both expressions can mean that something changes based on another factor.

In English, both may be translated as:

according to

depending on

in response to

to match

to suit

However, their core feeling is different.

「に応じて」 means “in response to a condition, degree, or change.”

「に合わせて」 means “to adjust something so that it matches a person, standard, timing, or situation.”

This difference is important in JLPT N2 grammar questions, especially when the sentence sounds formal.

The core meaning of 「に応じて」

「に応じて」 means:

depending on

in response to

according to the condition or degree of something

It is a relatively formal expression and often appears in written Japanese, business documents, news, explanations of systems, and official rules.

For example:

成績に応じて、奨学金の金額が変わります。
The amount of the scholarship changes according to one’s grades.

Here, 「成績」 means “grades.”

The amount changes depending on the level of the grades.

So the focus is not “matching” something gently, but “responding to a condition or degree.”

Other examples:

経験に応じて、担当する仕事が決まります。
The work assigned is decided according to one’s experience.

売上に応じて、ボーナスが支給されます。
Bonuses are paid according to sales performance.

年齢に応じて、必要な栄養の量は変わります。
The necessary amount of nutrition changes depending on age.

In these examples, 「経験」「売上」「年齢」 are conditions or degrees.

The result changes in response to them.

The feeling of 「に応じて」

The basic image of 「に応じて」 is:

look at the condition

look at the degree

look at the situation

respond appropriately

That is why 「に応じて」 is often used with nouns such as:

能力に応じて
according to ability

成績に応じて
according to grades

年齢に応じて
according to age

状況に応じて
depending on the situation

必要に応じて
as needed

人数に応じて
according to the number of people

売上に応じて
according to sales

変化に応じて
in response to changes

These nouns usually express a condition, degree, scale, or change.

The core meaning of 「に合わせて」

「に合わせて」 means:

to match

to suit

to adjust to

in accordance with

It is used when something is adjusted so that it fits another person, standard, timing, or situation.

For example:

学生のレベルに合わせて、授業の内容を変えます。
I change the lesson content to match the students’ level.

Here, 「学生のレベル」 is the standard.

The teacher adjusts the lesson so that it fits the students.

The focus is not a formal response to a condition, but adjustment so that the content becomes suitable.

Other examples:

相手の都合に合わせて、会議の時間を決めます。
We decide the meeting time to match the other person’s schedule.

季節に合わせて、メニューを変えています。
We change the menu to suit the season.

音楽に合わせて、子どもたちが踊っています。
The children are dancing to the music.

お客様の希望に合わせて、プランを作成します。
We create a plan to match the customer’s wishes.

In these examples, the speaker adjusts something so that it fits a person, preference, timing, or rhythm.

The feeling of 「に合わせて」

The basic image of 「に合わせて」 is:

look at the person

look at the standard

look at the timing

adjust so that it fits

That is why 「に合わせて」 is often used with nouns such as:

相手に合わせて
to match the other person

レベルに合わせて
to match the level

都合に合わせて
to fit someone’s schedule

予定に合わせて
to match the plan or schedule

季節に合わせて
to suit the season

音楽に合わせて
to match the music

希望に合わせて
to match someone’s wishes

生活スタイルに合わせて
to suit one’s lifestyle

Compared with 「に応じて」, 「に合わせて」 has a stronger feeling of “making something fit well.”

The biggest difference between 「に応じて」 and 「に合わせて」

The main difference is this:

「に応じて」 means responding to conditions, degree, or changes.

「に合わせて」 means adjusting something so that it matches a person, standard, timing, or situation.

Compare these two sentences:

人数に応じて、料理の量を増やします。
We increase the amount of food according to the number of people.

人数に合わせて、料理の量を調整します。
We adjust the amount of food to match the number of people.

Both sentences are natural.

But the feeling is slightly different.

「人数に応じて」 sounds more formal and system-like. It means that the amount changes in response to the number of people.

「人数に合わせて」 sounds more practical and adjustment-focused. It means that the amount is adjusted so that it fits the number of people.

「に応じて」 is common in formal and business contexts

「に応じて」 is often used in business writing, official explanations, and formal situations.

市場の変化に応じて、販売戦略を見直します。
We will review our sales strategy in response to changes in the market.

注文数に応じて、納期を調整いたします。
We will adjust the delivery date according to the number of orders.

リスクの大きさに応じて、対応方法を検討します。
We will consider response methods according to the level of risk.

In these sentences, the speaker looks at a condition or situation and chooses an appropriate response.

This is why 「に応じて」 often sounds formal, objective, and business-like.

「に合わせて」 is useful for everyday adjustment

「に合わせて」 can also be used in business, but it is very common in everyday Japanese too.

あなたの予定に合わせて、出発時間を決めます。
I will decide the departure time to match your schedule.

子どもの成長に合わせて、服を買い替えます。
We buy new clothes according to the child’s growth.

料理は家族の好みに合わせて、少し甘くしました。
I made the dish a little sweeter to suit my family’s taste.

In these sentences, the speaker adjusts something to fit a person, schedule, growth, or preference.

Common JLPT N2 point

In JLPT N2 questions, do not memorize 「に応じて」 and 「に合わせて」 as exactly the same.

Look carefully at the noun before the expression.

「に応じて」 is often natural after words such as:

必要
need

状況
situation

程度
degree

能力
ability

成績
grades

売上
sales

人数
number of people

変化
change

「に合わせて」 is often natural after words such as:

相手
the other person

予定
schedule

都合
convenience or availability

希望
wishes

レベル
level

音楽
music

季節
season

生活スタイル
lifestyle

Of course, there are cases where both can be used.

But ask yourself:

Is the sentence about responding to a condition?

Then 「に応じて」 is likely to be natural.

Is the sentence about adjusting something so that it fits?

Then 「に合わせて」 is likely to be natural.

Examples that are easy to confuse

Compare these two sentences:

お客様の希望に応じて、商品を作ります。
We make products according to customers’ wishes.

お客様の希望に合わせて、商品を作ります。
We make products to match customers’ wishes.

Both are possible.

「希望に応じて」 sounds more formal, like a company service explanation.

「希望に合わせて」 sounds more natural and emphasizes adjustment to the customer’s wishes.

Now compare these:

音楽に応じて、踊ります。
This sounds unnatural in most contexts.

音楽に合わせて、踊ります。
We dance to the music.

Here, 「音楽に合わせて」 is natural because dancing follows the rhythm of the music.

The idea is “matching,” not “responding to a condition.”

季節の変化に応じて、体調管理の方法を変えましょう。
Let’s change how we manage our health according to seasonal changes.

参加人数に応じて、会場の広さを決めます。
We decide the size of the venue according to the number of participants.

Summary

「に応じて」 and 「に合わせて」 are both used when something changes based on something else.

But their core meanings are different.

「に応じて」 means responding to conditions, degree, situations, or changes.

「に合わせて」 means adjusting something so that it matches a person, standard, timing, or situation.

For JLPT N2, pay attention to the noun before the grammar pattern.

If the noun is 「能力」「成績」「必要」「状況」「変化」, 「に応じて」 is often natural.

If the noun is 「相手」「予定」「都合」「音楽」「レベル」「希望」, 「に合わせて」 is often natural.

Understanding this difference will help you choose the correct expression in grammar questions and understand formal Japanese more accurately.
