「Describing the existence of animate and inanimate things」
Terebi ga aru/arimasu.
There is a TV set.
Otoko no ko ga iru/imasu.
There are boys.
In Japanese, two different verbs are used to express the idea that someone or something exists. Aru ("there is") is used with inanimate objects such as books, plants, buildings, etc,, while iru ("there is") is used with animate objects such as people, animals, and insects. The polite forms are arimasu, and imasu, respectively.
When the particle mo ("also") is used in a sentence where the topic is of the existence of someone or something, it replaces the subject marker ga.
Kōban ga arimasu.
There is a police box.
Keikan ga imasu.
There is a policeman.
Shiroi tori ga iru. Aoi tori mo iru.
There are white birds. There are also blue birds.
