Kawaii かわいい or 可愛い is the culture of cuteness in Japan. It can refer to items, humans, and non-humans that are charming, vulnerable, shy, and childlike. Examples include cute handwriting, certain genres of manga, anime, and characters including Hello Kitty and Pikachu from Pokémon.
The cuteness culture, or kawaii aesthetic, has become a prominent aspect of Japanese popular culture, entertainment, clothing, food, toys, personal appearance, and mannerisms.
The word kawaii originally derives from the phrase 顔映し kao hayhushi, which literally means "(one's) face (is) aglow," commonly used to refer to flushing or blushing of the face. The second morpheme is cognate with -bayu in mabayui (眩い, 目映い, or 目映ゆい) "dazzling, glaring, blinding, too bright; dazzlingly beautiful" (ma- is from 目 me "eye") and -hayu in omohayui (面映ゆい) "embarrassed/embarrassing, awkward, feeling self-conscious/making one feel self-conscious" (omo- is from 面 omo, an archaic word for "face, looks, features; surface; image, semblance, vestige"). Over time, the meaning changed into the modern meaning of "cute" or "shine" , and the pronunciation changed to かわゆい kawayui and then to the modern かわいい kawaii. It is commonly written in hiragana, かわいい, but the ateji, 可愛い, has also been used. The kanji in the ateji literally translates to "able to love/be loved, can/may love, lovable."
The original definition of kawaii came from Lady Murasaki's 11th-century novel The Tale of Genji, in which it referred to pitiable qualities. During the Shogunate period under the ideology of neo-Confucianism, women came to be included under the term kawaii as the perception of women being animalistic was replaced with the conception of women as docile. However, the earlier meaning survives into the modern Standard Japanese adjectival noun かわいそう kawaisō (often written with ateji as 可哀相 or 可哀想) "piteous, pitiable, arousing compassion, poor, sad, sorry" (etymologically from 顔映様 "face / projecting, reflecting, or transmitting light, flushing, blushing / seeming, appearance").
