Particles are small suffixes that follow a word to define its grammatical function in the sentence.

The Topic Particle は

The particle は (written as は but pronounced “wa”) identifies the topic of the sentence.

Examples

(わたし)学生(がくせい)だ。As for me, I am a student.
友達(ともだち)日本人(にっぽんじん)だ。As for my friend, he is Japanese.
映画(えいが)面白(おもしろ)い。As for the movie, it is interesting.

The Subject Particle が

The particle が identifies the specific subject that is performing the action or state.

Examples

(だれ)()ましたか?Who came?
(みず)()しい。I want water.
(ねこ)がいる。There is a cat.

The Object Particle を

The particle を (pronounced “o”) marks the direct object of a verb—the thing that is being acted upon.

Examples

(ほん)()む。Read a book.
映画(えいが)()る。Watch a movie.
友達(ともだち)()う。Meet a friend.

The Target/Direction Particle に

The particle に indicates a target location, time, or movement towards something.

Examples

学校(がっこう)()く。Go to school.
(なな)()()きる。Wake up at 7 o'clock.
友達(ともだち)(はな)す。Talk to a friend.

The Direction Particle へ

This particle (pronounced “e”) is similar to に but emphasizes direction rather than the destination itself.

Examples

日本(にっぽん)()く。Go towards/to Japan.
(ひがし)(すす)む。Proceed eastward.
未来(みらい)()かう。Head toward the future.

Note: に vs へ — When to use which?

Both に and へ can indicate direction/destination, but they have subtle differences:

Use に when:

  • You emphasize the arrival point or specific destination
  • Indicating a precise time (へ cannot be used for time)
  • Marking the recipient of an action (indirect object)
  • Describing purpose with verbs of motion
(えき)()いた。I arrived at the station. (arrival point)
(さん)()()う。Meet at 3 o'clock. (time - only に works)
(かれ)(ほん)をあげた。I gave him a book. (recipient - only に works)
買い物(かいもの)()く。Go shopping. (purpose - only に works)

Use へ when:

  • You emphasize the direction or journey rather than arrival
  • The destination is abstract or metaphorical
  • You want a softer, more literary tone
(きた)()かう。Head northward. (direction emphasis)
成功(せいこう)(すす)む。Advance toward success. (abstract destination)
故郷(こきょう)(かえ)る。Return to my hometown. (emotional/literary)

Interchangeable cases:

学校(がっこう)()く。 / 学校(がっこう)()く。Go to school. (both work, に slightly more common)

Note: は vs が — The topic-subject distinction

This is one of the trickiest distinctions in Japanese. Here’s when to use each:

Use は (topic marker) when:

  • Introducing known/old information as the topic
  • Making general statements or descriptions
  • Contrasting one thing with another
  • The information about the topic is the focus
(わたし)学生(がくせい)です。I am a student. (introducing yourself)
(ぞう)(はな)(なが)い。Elephants have long noses. (general fact)
(にく)()べるが、(さかな)()べない。I eat meat, but I don't eat fish. (contrast)
田中(たなか)さんは()ました。Tanaka-san came. (focus: the coming)

Use が (subject marker) when:

  • Introducing new/unknown information
  • Answering “who/what” questions
  • Describing existence (いる/ある)
  • Expressing desires, abilities, likes (()しい, できる, ()き)
  • In subordinate clauses
(だれ)()た? 田中(たなか)さんが()た。Who came? Tanaka-san came. (new info)
(ねこ)がいる。There is a cat. (existence)
(みず)()しい。I want water. (desire)
日本語(にほんご)ができる。I can speak Japanese. (ability)
(わたし)(つく)った料理(りょうり)The food that I made. (subordinate clause)

Key difference in nuance:

(わたし)()く。As for me, I will go. (maybe others won't)
(わたし)()く。I will go. (I'm the one, not someone else)
