Do you know how to read in Japanese? If not, this article has romaji versions of the vocabulary to help you out. However, we encourage you to learn Japanese alphabet so you can read the words in hiragana and katakana, too.

Let’s get started!

How to Say “Friend” in the Japanese Language

The following words are the most basic ways to say “friend” in Japanese.

  • ともだち (tomodachi | 友達)
  • ゆうじん (yuujin | 友人)
  • とも (tomo | 友)

In Japanese, ともだち (tomodachi | 友達) and ゆうじん (yuujin | 友人) both mean “friend.” However, a native Japanese speaker can use the two words differently depending on the situation.

Example Sentences

あたらしいともだちができた。(atarashii tomodachi ga dekita. | 新しい友達ができた。)

I made a new friend.

わたしたちはともだちです。 (watashi tachi wa tomodachi desu. | 私たちは友達です。)

We’re friends.

かれはわたしのゆうじんです。(kare wa watashi no yuujin desu. | 彼は私の友人です。)

He is my friend.

るいはともをよぶ (rui wa tomo wo yobu. | 類は友を呼ぶ )

Birds of a feather flock together. (Like attracts like.) *Literally, “like calls their friend.

As a Japanese learner, you may find it is not as easy as it seems to use these expressions correctly. In this chapter, we focus on the definition of each word.

For A Casual Conversation

ともだち (tomodachi | 友達) fits in various situations when you’re talking casually to a “friend” and is usually used by young people in written and spoken Japanese.

Example Sentences

かのじょとはただのともだちだよ。(kanojo to wa tada no tomodachi dayo. | 彼女とはただの友達だよ。)

She is just a friend.

あしたは、ともだちとあそびにいくんだ。(ashita wa, tomodachi to asobi ni iku n da. | 明日は、友達と遊びに行くんだ。)

I will go out with my friends tomorrow.

For A Very Formal Conversation

On the other hand, ゆうじん (yuujin | 友人) is the appropriate word to use for “friend” in a very formal conversation and ですます (desu masu) ending speeches. It can also highlight multiple friends.

Example Sentence:

あすはゆうじんたちとでかけるよていです。(asu wa yuujin tachi to dekakeru yotei desu. | 明日は友人たちと出掛ける予定です。)

I plan to go out with friends tomorrow.

For Formal Written Communication

Two friends sharing heartfelt letters, one reading and the other writing.

とも (tomo | 友 ) is commonly used in written communications and formal situations.

Example Sentence

しんあいなるともへ (shinai naru tomo he | 親愛なる友へ )

Dear friend.

For Business and Formal Situations

By adding お (o) or ご (go) to the noun, you can politely address someone’s friends or companions in Japanese.

You will likely hear ごゆうじん (go-yuujin | ご友人) instead of おともだち (o-tomodachi | お友達) in a very specific scene of formal conversation, including condolences and business partner conversations.

Example Sentences

おともだちしょうかいキャンペーン (o tomodachi shoukai kyanpeen | お友達紹介キャンペーン )

Refer-a-friend program.

ごゆうじんをなくされたしんちゅう、おさっしします。(go yuujin wo nakusareta shinchuu, osasshi shimasu. | ご友人を亡くされた心中、お察しします。)

My heart goes out to you for the loss of your friend.

How to Say “Friend” in Singular and Plural Forms in Japanese

The Japanese language usually doesn’t have a plural form like the English word, but some rules apply to the singular and plural forms for “friend.”

Singular Form of “Friend” in Japanese

The “to become friends” phrases always use a singular form.

Example Sentences

Plural Form of “Friend” in Japanese

  • To clarify or suggest the number of friends, add ~にんの (in no | ~人の | of people) or other quasi-adjectives.

たくさんのともだち (takusan no tomodachi | たくさんの友達 )

おおくのゆうじんたち (ooku no yuujin tachi | 多くの友人たち )

Plural Suffixes

Japanese has four plural suffixes referring to a person, social group, or company, and commonly written in ひらがな (hiragana | 平仮名) forms.

The following suffixes work similarly to the English -s with the word friend. Yet, it sometimes indicates modesty, respect, or disrespect. Please pay attention to the context and tone when you use it.

  • ~たち (tachi | 達 | -s)
  • ~がた (gata | 方 | -s) *Formal version
  • ~ら (ra | 等 | -s)
