と is a particle in Japanese that denotes a noun as being connected to a proceeding noun in an exclusive list. It can be used multiple times in a sentence, adding more and more nouns together when used in sequence.

Example: I'm going to eat tomatoes, bananas, cake, ramen and sushi.

Info

In this example, γƒˆγƒžγƒˆ is marked by the と particle, meaning it is connected to the proceeding noun γƒγƒŠγƒŠ.

γƒγƒŠγƒŠ is also marked by と, connecting both it and it’s connected noun γƒˆγƒžγƒˆ to the proceeding noun γ‚±γƒΌγ‚­.

γ‚±γƒΌγ‚­ is also marked by と, connecting it and all of it’s connected nouns to the proceeding noun ラーパン.

ラーパン is also marked by と, connecting it and all of it’s connected nouns to the proceeding noun すし.

すし is marked by γ‚’, and as it is connected to a list of nouns, this entire list is marked as the object of the sentence. The entire list is the object of the primary verb.

The context of the action being performed is provided by the verb γŸγΉγ‚‹ (eat).

The subject of the sentence is inferred from context to be γ‚γŸγ— (I), as the が particle is invisible/omitted.
