How to Say Friend in Japanese: 12 Natural Ways

The generic word for friend in Japanese is 友人 (yuujin). Japanese people have many different ways to say the word friend. These words depend on how close the relationship is and with whom they are speaking. This article will discuss the words you can use to talk about your friend in Japanese. 

Be aware that, unlike in other languages such as English, it isn’t common to refer directly to your friend with these words. They will typically be used to introduce them to other people.

Common Words for Friend in Japanese

Here are some general words for friend in Japanese. Be careful to note the level of politeness or intimacy in each!

1. 友達 ( Tomodachi ) – Friend

The word 友達 (tomodachi) means friend or friends. The suffix -達 (dachi) is technically the Japanese plural form, but you can use tomodachi to refer to either one friend or many.

The word tomodachi is more casual than the previously mentioned yuujin.  Tomodachi is not a slang word, but it also isn’t polite or honorific Japanese. Be sure to use tomodachi only if you’re speaking with your peers, friends, or family.


  1. My friend Tom is coming over tonight.   –    今夜、友達のトムさん が遊びに来る。 (Konya, tomodachi no Tom-san ga asobi ni kuru.)
  2. I went to the mall with my friends yesterday.   –   昨日、友達と一緒にモールに行った。 (Kinou, tomodachi to issho ni mooru ni itta.)

2. 友人 ( Yuujin ) – Friend (Polite)

As mentioned at the beginning of this article, 友人 (yuujin) is the basic and polite way to say friend in Japanese. Translated, it means familiar/friendly person. 

Yuujin is a “safe” way to say friend in Japanese because it’s polite—but not too polite. This means that you can use it with people in your inner circle and not come across as cold or aloof. While tomodachi and yuujin mean the same thing, there is a marked difference in when and where you can use them. If you’re feeling uncertain, it might be best to stick with the word yuujin. 


  1. I received this hat from a friend.   –   この帽子を友人からもらいました。 (Kono boushi o yuujin kara moraimashita.)

3. 親友 ( Shinyuu ) – Best Friend

In Japanese, the word 親友 (shinyuu) is reserved for close friends or friends who you’ve known for a long time. It derives from the same kanji as the adjective 親しい (shitashii), or intimate. You can also refer to a close friend as 親しい友達 (shitashii tomodachi) or 親しい友人 (shitashii yuujin) for the same effect. 

Shinyuu has the same nuance as the English phrase best friend. You can make this word even stronger by saying 大親友 (daishinyuu), or very best friend.


  1. Tarou has been my best friend since childhood.   –   太郎は子供ころからの親友です。 (Tarou wa kodomo kara no shinyuu desu.)
  2. I sent a card to my dear friend in the hospital.   –   入院 した親しい友達にカードを送りました。 (Nyuuin shita shitashii tomodachi ni kaado o okurimashita.)

4. 仲間 ( Nakama ) – Companion, Comrade

A danger of learning Japanese only through manga or anime is that you might find misleading translations for words like 仲間 (nakama). Many media platforms translate nakama into “friend” or even “buddy.” In reality, the word has far less familiarity with its meaning.

In Japanese, nakama implies comradery, but not necessarily friendship. Your nakama could be a fellow player on your basketball team. They are your nakama whether you are close friends or not. 

Of course, nakama does have a positive nuance. It would not be correct to refer to a teammate you dislike as nakama. However, it is a common mistake to refer to your bosom buddy or childhood friend as nakama. Use this word for friend with care.


  1. Please let me join your team!   –   仲間に入れてください! (Nakama ni irete kudasai!)

5. 味方 ( Mikata ) – Ally, Partner, Comrade

The word 味方 (mikata) is also used often in Japanese media. For this reason, it also suffers from some translation issues. Mikata means ally or partner in English. It is used to describe someone who shares the same group or circumstances that you do. 

Like with nakama, you should avoid using the word mikata for people you don’t really like. It is still a far less endearing term than tomodachi or yuujin. 


  1. Yoko took sides with me when the teacher got mad at me.   –   先生に怒られたとき、洋子さんは私の味方になってくれた。(Sensei ni okorareta toki, Youko-san wa watashi no mikata ni natte kureta.) 
  2. I thought you were my ally, but you betrayed me.   –   味方だと思ってたのに、裏切られた。 (Mikata dato omotteta noni, uragirareta.) 

Situational Words for Friend

Some words for friend in Japanese can only be used in certain situations or professional relationships. Here are some situation-specific ways to say friend.

6. 相棒 ( Aibou ) – Partner

相棒 (aibou) is a common word for friend in Japanese—so long as you and that friend share a  same goal or purpose and works towards it together. . In certain situations, aibou can even be used to speak about a friend who is also your business partner. Detectives in Japanese dramas may also call each other aibou. This word is a bit friendlier than nakama but is in the same subgenre of meaning.

If you can read the kanji, you may be a little confused.  The kanji is comprised of 相 (ai, meaning mutual or each other) and 棒 (bou, meaning stick or rod).  What does a stick have to do with being friends?  

The origin of the word aibou comes from 2 people who carried a basket (called “kago”) that was used to transport a person back in the Edo era.  The pair of basket carriers (called “kago hiki”) called each other aibou.  You can read more about it here in Japanese:  The meaning of aibou (website in Japanese only).


  1. My partner here is a well-known writer.   –   うちの相棒はかなり有名な作家です。 (Uchi no aibou wa kanari yuumei na sakka desu.)

7. 同僚 ( Douryou ) – Colleague, Associate

If you are friends with a colleague or a close associate, 同僚 (douryou) would be a suitable word to use. 同 (dou) means “same” in Japanese and is used in many other terms. Because douryou implies a similaritybetween you and your friend, you wouldn’t be able to use the word for a friend in a different workplace or career than yourself.


  1. Today, my coworker and I went to a ramen shop for our lunch break.   –   今日の昼休みに、同僚と一緒にラーメン屋へ食べに行った。 (Kyou no hiruyasumi ni, douryou to issho ni raamen-ya e tabe ni itta.)

8. 同級生 ( Doukyuusei ) – Classmate, Peer

The word 同級生 (doukyuusei) is a way to say friend or peer in Japanese. It’s rooted in Japanese 先輩・後輩 (senpai/kouhai), or senior/junior culture. A doukyuusei is neither a senpai (senior) or a kouhai (junior). They are someone who is right on level with you, either in age or in rank. Dokyuusei is most often used to refer to a friend who is also a classmate in the same grade.


  1. John and I were classmates in elementary and middle school.   –   ジョンさんとは小学校と中学校で同級生だった。(Jon-san towa shougakkou to chuugakkou de doukyuusei datta.)

Japanese Slang Words for Friend

Like any other language, Japanese has slang words. Here are a few popular slang terms for friend. Be sure not to use them with your boss or with your elders!

9. 友 ( Tomo ) – Friend (Casual)

You may recognize the kanji in the word 友 (tomo). It’s the same as the first character in tomodachi, and the meaning is the same. Removing the suffix (-dachi) and just saying “tomo” is a more casual way to say friend in Japanese.


  1. Good morning, friend!   –   友よ!おはよう! (Tomo yo! Ohayou!)

10. ダチ ( Dachi ) – Pal, Buddy, Bro

This is the same rule as with tomo but applied to the second half of tomodachi. Although it’s always written in katakana, ダチ (dachi) is the same 達 (dachi) in 友達. 

This is a very casual Japanese slang word. It’s an older term that might not be trendy in daily conversation but is sure to show up in TV dramas or anime. Dachi is also used between friends as a joke or an endearing tease.


  1. We’re pals, right?   –   俺たちはダチでしょう? (Oretachi wa dachi deshou?)

11. ツレ ( Tsure ) – Companion

ツレ (tsure) is a Japanese slang word for friend used during social events. It derives from the word 連れ (tsure), or to bring. The implication is that this friend is your “plus one”—it can be romantic or platonic.


  1. I came with my wife, Misaki.   –   私のツレは妻の美咲です。 (Watashi no tsure wa tsuma no Misaki desu.)

12. バディー ( Badii ) – Buddy, Compatriot, Partner

As it is a loan word, バディー (badii) is a very casual way to say partner or friend in Japanese. It isn’t a mainstream slang word anymore, but you can still hear it in a classic detective movie or read it in a manga.


  1. I swear, I’ll save my partner!   –   俺のバディーを絶対に助けに行く! (Ore no badii o zettai ni tasuke ni iku!)


There are various ways to say friend in Japanese, depending on your relationship with the friend or the company you find yourself in. If you’re in a pinch, the words yuujin and tomodachi are the most frequently used and are okay to use in most situations.
