0078 – Japanese basics (N5-N3) – Duration

grammar

How can I say in Japanese that I (have) studied Japanese for 3 years?

 

Grammar pattern with duration information

 

When adding a durational information, 

 

Duration + verbal expression

 

is usually used.

 

So for example, 

 

日本語を3年勉強しました

nihongo wo san nen benkyoo shi mashita.

I (have) studied Japanese for 3 years.

 

Durational expression

 

In Japanese, instead of adding a preposition like “for” in English, a durational expression is typically made by combining time word and 

 

: kan: for

 

But there are something to watch out:

 

  • 間: kan: for is optional EXCEPT hour and week
  • One day is usually said without 間

 

And here’s the lists of durational expressions in Japanese:

 

Hour:

昨日、8時間寝ました。

kinoo hachi jikan ne mashita.

I slept for 8 hours yesterday.

 

Day:


今月、3日(間)働きました。

kongetsu, mi kka (kan) hataraki mashita.

 

Week:


山の中で3週間スキーをしました。

Yama no naka de san syuukan sukii wo shi mashita.

I skied at a mountain for 3 weeks.

 

Month:


日本に4か月(間)います。

Nihon ni yon kagetsu (kan) i masu.

I have been in Japan for 4 months.

 

Year:


フランスで3年(間)料理を勉強しました。

Huransu de san nen(kan) ryoori wo benkyoo shi mashita.

I learnt how to cook for 3 years in France.

 

How to make questions with duration expressions?

 

When making questions, you can either

 

  • Replace the number part with 何:nan: what
  • Use どのくらい: donokurai: How long

 

So, for example, 

 

A:

日本語を何年(間)(どのくらい)勉強しましたか。

nihongo wo nan nen (kan) (donokurai) benkyoo shi mashita ka.

How many years (How long) have you studied Japanese approximately?

 

 B:

3年(間)ぐらい勉強しました。

san nen (kan) gurai benkyoo shi mashita.

I’ve studied for around 3 years.
