there is; is (non-living things)
States existence or presence of non-living things (and some living things like plants), politely.
This is the polite way to say that something exists or is present. It is used for non-living things (objects, places, events) and also for plants. For living beings (people, animals), you use がいます instead. The subject marker が is used before あります, and the thing that exists is often marked with が or sometimes は for contrast (e.g., 本はあります). This pattern is common in everyday conversation, especially when describing what is in a place or what you have.
