Sentence Structure

In this chapter the structure of Japanese sentence is explained

General Structure

The general structure of a sentence in Japanese is: <subject> <object> <verb> To show which part of a sentence is what subject and objects are usually marked with particles like wa, ga, or, etc.

No Particle

no is the genitive particle and can combine multiple nouns. It is used like N1 no N2. N2 belongs to N1.

watashi no kodomo = my child
IMC no kaishan = IMC employee

Wa vs Ga

Wa and ga can sometimes be used interchangeably. As a rule of thumb: Ga is for new or unkown topics and wa is for already introduced topics

As en example:

Yamada-san ga yasashii desu. = Yamanda is kind
Yamada-san wa omoshiroi desu. = Yamada is funny

In the first sentence we use ga because there is a new topic, Yamada-san. In the second sentence we’re already talking about Yamada-san and thus we use wa.

Wa and ga can also be used to emphasize part of the sentence. In English, we usually do this by raising our voice.

1. Sushi wa oishii desu. = Sushi is delicious.
2. Sushi ga oishii desu. = Sushi is delicious.

In the first sentence the “delicious” part is important while in the second sentence the emphasizes is on sushi. Ga as But _________ ga if used in the middle of a sentence, means “but” or “however”.

Sushi wa tabemasu ga, sakana wa tabemasen. = (I will) eat sushi, but (I will) no eat fish.

Wa to constrast

wa can be used to highlith the difference between to objects or subjects. It will replace o or ga. This can be useful in sentence where two things are compared like with “but” or “however” (see But (or) However for “but” and “however” sentences)

Kocha wa nomimasu. Demo, kohi wa nomimasen = (I) drink tea. However, (I) don’t drink coffee.

Mo

mo means also/as well and replaces the wa particle

Santou-san mo kaishan desu = Santou-san is also an employee.

O Particle

The o particle has several uses and the following list isn’t complete.

Object Particle

The o particle can be used to mark the object. Example:

Ringo o tabemasu. = (I) eat an apple.
Orenji-jusu o nomimasu = (I) drink orange juice

Where You Leave

The o particle can also be used to show where you leave or depart from. Here are a few examples:

Ie o demasu. = (I will) leave the house.
Baseu o orimasu. = (I will) get off the bus.
Shigoto o yasumimasen. = (I will) not have a break from work.

Ni Particle

ni is known as the location particle and can be loosely translated to “in”, “on”, “at” or “to” depending on the usage. It’s important to remember that its usage isn’t always the same as in english.

ni is often used together with a verb of motion, like “come”, “go” or “walk” in a structure like <noun> ni <verb of motion>

Show a destination

ni can be used to show a destination.

Eki ni ikimasu. = (I will) go to the train station.
Densha ni norimasu. = (I will) ride the train.
Hon op kaban ni iremasu. = (I will) put the book in (my) bag.

A Point of Contatct

With ni you can also show a point of contact with an other person.

Tomodachi ni denwa shimasu. = (I) will call (my) friend.
Raishu kazoku ni aimasu. = (I will) meet (my) famaly next week.

Mark the Time

You can also mark the time in a sentence, as long it isn’t a relative time pronoun, like “now” or “tomorrow”.

Shichi-ji ni ikimasu = (I will) go at seven o’clock

Mark a Place

If ni is placed at the start of a sentence, it indicates a location where the action takes place. ni can also be placed in the middle. This changes the focus of the sentence as seen in the following example.

Asoko ni inu ga imasu. = There is a dog over there.
Inu wa Asoko ni imasu. = The dog is over there.
Eki ni keisatsukan ga imasu. = There is a policeman at the train station.

To and Ya

In Japanese you use to and ya to say “and”.

to acts like the english counterpart “and” and connects to nouns, like so:

ringo to orenji = apples and oranges
ino to neko = dogs and cats
Keki to kukki to aisu o tabemsu. = (I will) eat cake, cookies and ice cream.

Note

to can also be used to mean “width” or “to” when it connects a noun to a verb, as the following example shows:

Tomodachi to asobimasu. = (I will) hang out with (my) friend.
Okasan to otosan to onesan to bangohan o tabemasu. = (I) eat dinner with (my) mom, dad and older sister.

ya is called the “listing particle” and is used to show that the list isn’t complete. It can be compared to “etc.” in English. Here are some examples:

Chokoreto ya keki ga suki desu. = (I) like chocolate and cake (and some other things).
Yasai ya sakana o kaimasu. = (I will) buy vegetables and fish (ands some other things).

Note

You can’t mix yo and to in the same list

Also Mo

The word mo can be translated to “also” or “too” and it replaces the wa, ga and o in a sentence.

Watashi mo suki desu! = I like (it) too! (wa was replaced by mo)
Yakyu ga suki desu. Sakka mo suki desu = (I) like baseball. (I) also like soccer.

To make everythingh a bit more complicated: If mo is used multiple times in a sentence, it also means “and”. But mo is used after every object/noun in the list.

Niku mo yasai mo oishi desu = Meat and vegetables are (both) delicious.
Watashi wa ryori mo e mo jozu desu. = I am good at (both) cooking and drawing.

But (or) However

“but” and “however” have multiple words in Japanese.

Note

ga can also be used to say “but” or “however” this however is described in Wa vs Ga

Demo

demo is used at the start of a sentence. If you want to be polite, you can use shikashi instead. This however is mostly used in writting or formal speeches.

Nihongo wa tanoshi desu. Demo, muzukashi desu. = Japanese is fun. However, (it) is difficult.
Nihongo wa tanoshi desu. Shikashi, muzukashi desu. = Japanese is fun. However, (it) is difficult.

Kedo

kedo can also join two sentences but compared to demo, it is in the middle of the final sentence. Like with demo and shikashi, there is also a polite version of kedo: keredo. It is also mostly used in formal speech or writing.

Sushi wa tabemasu kedo, sakana wa tabemasen. = (I will) eat sushi but (I will) not eat fish.
Inaka wa shizuka desu kedo, fuben desu. = The countryside is quiet but (it) is inconvenient.
Inaka wa shizuka desu keredo, fuben desu. = The countryside is quiet but (it) is inconvenient. (formal)
