Translation guide
In English, 'reflexive' refers to actions done to oneself, often using pronouns like 'myself', 'yourself', etc. In Japanese, this concept is expressed through specific verb forms, particles, or set phrases, and often the reflexive meaning is implied by context rather than explicitly stated.
Expressing that the subject performs an action on themselves, like 'I wash myself' or 'He hurt himself'.
Use 自分 (oneself) with the object particle を to explicitly indicate a reflexive action. This is the most direct way to express 'oneself'.
彼は自分を責めた。
He blamed himself.
I have to protect myself.
When the action involves a body part or personal item, use 自分の (one's own) to show it belongs to the subject. This is more natural than using a separate reflexive pronoun.
彼は自分の髪を切った。
He cut his own hair.
私は自分の部屋を掃除した。
I cleaned my own room.
Many English reflexive actions are expressed with intransitive verbs in Japanese, where the action happens to the subject without a direct object. Alternatively, the passive form can imply that the subject is affected by their own action.
ドアが開いた。
The door opened (by itself).
彼は事故で怪我をした。
He got injured in an accident (he injured himself).
In many cases, the reflexive meaning is understood from context, and adding 自分を would be redundant or unnatural. For example, 'I wash myself' is simply 顔を洗う (wash face) or 体を洗う (wash body) without specifying 'myself'.
毎朝、顔を洗います。
I wash my face every morning.
彼は手を挙げた。
He raised his hand.
Emphasizing that someone does something alone, without help, or personally, like 'I did it myself' or 'She went by herself'.
自分で means 'by oneself' or 'personally', emphasizing that the subject performs the action without assistance. It is used with volitional actions.
自分でやりました。
I did it myself.
彼女は自分で料理を作った。
She cooked the meal herself.
一人で means 'alone' or 'by oneself', focusing on being alone rather than the reflexive action. It is used when the emphasis is on solitude.
彼は一人で映画を見に行った。
He went to see a movie by himself.
自ら is a formal, literary word meaning 'personally' or 'oneself'. It is used in written language or formal speeches.
Verbs that describe actions typically done to oneself, like 'to wash oneself', 'to dress oneself', or 'to introduce oneself'.
自己紹介する means 'to introduce oneself'. It is a set phrase that inherently includes the reflexive meaning.
まず、自己紹介します。
First, I'll introduce myself.
着替える means 'to change clothes'. It implies changing one's own clothes, so the reflexive meaning is built in.
パジャマに着替えた。
I changed into my pajamas.
身を守る literally means 'to protect one's body', i.e., 'to protect oneself'. It is a common phrase for self-defense.
彼は身を守るために逃げた。
He ran away to protect himself.
Understanding how English reflexive pronouns like 'myself', 'yourself', etc., map to Japanese grammar, especially in contexts like 'I myself' or 'the president himself'.
自身 is a suffix meaning 'oneself' or 'personally'. It attaches to nouns or pronouns for emphasis, similar to 'myself', 'yourself', etc.
私自身はその計画に反対です。
I myself am against the plan.
彼自身がそれを認めた。
He himself admitted it.
自分自身 is a stronger, more emphatic form of 自分, meaning 'oneself' or 'one's own self'. It is used for emphasis or clarity.
While 自分を is grammatically correct for reflexive actions, it can sound unnatural or overly explicit in many everyday situations. Japanese often omits the reflexive object when it's clear from context, especially with body parts or personal actions. For example, 'I wash my hands' is naturally 手を洗う, not 自分の手を洗う.
手を洗ってください。
Please wash your hands.
自分で emphasizes doing something by one's own effort or ability, while 一人で emphasizes doing something alone, without company. Use 自分で when you want to say 'I did it myself (without help)', and 一人で when you mean 'I did it alone (by myself, no one else was there)'.
このケーキは自分で作りました。
I made this cake myself (without help).
一人でケーキを全部食べた。
I ate the whole cake by myself (alone).
彼は独学で日本語を学んだ。
He taught himself Japanese.
独学で means 'by self-study', a natural way to express learning something by oneself.
彼女は鏡で自分の姿を見た。
She looked at herself in the mirror.
自分の姿 (one's own reflection) is more natural than 自分を directly.
自分に新しいスマホを買った。
I bought myself a new phone.
自分に (for oneself) is used for indirect reflexive actions like buying something for oneself.
社長自らが出席した。
The president himself attended.
自分自身を信じなさい。
Believe in yourself.
