shiroi

Shiroi is the Japanese adjective 白い, meaning "white." In Japanese, shiroi describes the color of nouns and can modify nouns directly (for example, shiroi hana, white flower) or function as the predicate (Kono hana wa shiroi desu, The flower is white).

It is an i-adjective derived from the noun shiro (white) with the characteristic i ending. The standard spelling uses the kanji 白い for writing, though it is commonly written in kana as しろい in everyday text.

Shiroi is also used as a place name. Shiroi is a city in Chiba Prefecture, Japan, written 白井市 in kanji and read Shiroi-shi in Japanese. In English, the city is typically rendered as Shiroi.

In popular culture and commerce, the term appears in notable uses such as Shiroi Koibito Park in Sapporo, Hokkaido. This park is built around the Shiroi Koibito cookie, produced by Ishiya; the product name translates roughly as "White Lover" and is marketed as a white chocolate sandwich cookie. The name highlights the association with whiteness, an often-desired quality in the cookies.

Beyond proper nouns, shiroi remains a basic color term in Japanese, used to describe snow, clouds, fur, and other white objects. It is a common descriptor in everyday language as well as in literature and media.
