N4 · Context

As you advance to N4, grammar alone isn’t enough; you need the words to fuel those sentence structures! This chapter organizes essential N4 vocabulary thematically. By grouping words into categories like family, work, and emotions, you can memorize them more naturally through association.

1. Family & Relatives (家族と親戚)

In Japanese, there are two sets of words for family members: humble words (used when talking about your own family) and polite words (used when talking about someone else’s family). At N4, you need to know both sets.

MeaningMy Family (Humble)Someone Else’s (Polite)
Grandfather祖父 (そふ, sofu)おじいさん (ojiisan)
Grandmother祖母 (そぼ, sobo)おばあさん (obaasan)
Father父 (ちち, chichi)お父さん (otousan)
Mother母 (はは, haha)お母さん (okaasan)
Older Brother兄 (あに, ani)お兄さん (oniisan)
Older Sister姉 (あね, ane)お姉さん (oneesan)
Younger Brother弟 (おとうと, otouto)弟さん (otoutosan)
Younger Sister妹 (いもうと, imouto)妹さん (imoutosan)
Wife妻 (つま, tsuma) / 家内 (かない, kanai)奥さん (おくさん, okusan)
Husband夫 (おっと, otto) / 主人 (しゅじん, shujin)ご主人 (ごしゅじん, goshujin)

私の父はエンジニアですが、田中さんのお父さんは医者です。

watashi no chichi wa enjinia desu ga, Tanaka-san no otousan wa isha desu.

My father is an engineer, but Mr. Tanaka's father is a doctor.

週末は妻と一緒に買い物に行きます。

3. Emotions & Description (感情と様子)

Expressing precisely how you feel or describing someone’s character is vital for deep communication.

WordRomajiMeaningType
嬉しいureshiiHappy, gladI-adj
悲しいkanashiiSadI-adj
寂しいsabishiiLonelyI-adj
怖いkowaiScary, frightenedI-adj
恥ずかしいhazukashiiEmbarrassing, shyI-adj
優しいyasashiiKind, gentleI-adj
厳しいkibishiiStrict, severeI-adj
真面目なmajime naSerious, earnestNa-adj

[!TIP] In Japanese, you cannot directly assert another person’s emotions using i-adjectives like 悲しい (sad) or 嬉しい (happy). You must use phrases that indicate appearance, such as 悲しそうです (seems sad), which we will learn later in N4 grammar, or quote them.

テストに合格して、とても嬉しいです。

tesuto ni goukaku shite, totemo ureshii desu.

I passed the test, so I am very happy.

友達が転校してしまって、今は寂しいです。

tomodachi ga tenkou shite shimatte, ima wa sabishii desu.
