白い
しろい
shiroi
= white; pure white
白い (shiroi) is one of the first color words every Japanese learner encounters — a simple, crisp i-adjective that pops up everywhere from describing snow to expressing purity and innocence in Japanese culture.
白い means ‘white’ and functions as a standard i-adjective, conjugating to 白く (shiroku) in adverbial form and 白くない (shirokkunai) in the negative. It describes the literal color of objects (white paper, white shirt) but also carries connotations of cleanliness, freshness, and blankness. In everyday speech, 白い is used far more than its noun counterpart 白 (shiro) when directly modifying a noun — you say 白いシャツ (shiroi shatsu, white shirt) rather than 白シャツ except in compound nouns. The word can also appear in figurative expressions: 白い目で見る (shiroi me de miru) means to look at someone with cold, suspicious eyes — ‘white eyes’ implying distance or disapproval.
Don’t confuse 白い (shiroi, white as an adjective) with 白 (shiro, white as a noun or in compounds). Say 白い雪 (shiroi yuki, white snow) but 白黒テレビ (shirokuro terebi, black-and-white TV). Also watch out for 白っぽい (shiroppoi), which means ‘whitish’ or ‘off-white’ — useful when the color isn’t quite pure white. In casual speech, 白 alone is often enough when the context is clear, like naming a color in a game or choosing paint.
白 combines the sun radical (日) with a small stroke at the top, and its original pictographic meaning points to the pure light of the sun. The character is used in many compounds: 白黒 (shirokuro, black and white), 告白 (kokuhaku, confession), and 空白 (kuuhaku, blank space). The i-adjective suffix い turns the standalone noun 白 into the descriptive form 白い.

In Japanese tradition, white carries deep ceremonial significance — it is the color of mourning at funerals, where mourners wear white, and also the color of purity in Shinto rituals. Shinto priests and shrine maidens (miko) wear white robes, and the white of freshly washed rice is associated with sacredness. This dual role in both death rites and purification rituals reflects how 白 occupies a liminal space in the Japanese symbolic imagination, unlike in Western cultures where white is primarily associated with weddings and celebrations.
In modern Japanese pop culture, 白い is frequently used to describe aesthetic ideals. The phrase 白い肌 (shiroi hada, white skin) appears often in beauty advertising, reflecting longstanding beauty standards that prize lighter complexions. Meanwhile in anime and manga, characters with silver or white hair (often described as 白い髪, shiroi kami) are frequently coded as powerful, mysterious, or otherworldly — a visual shorthand that Japanese audiences immediately recognize.
