Kawaii ( かわいい ) is a Japanese term and aesthetic referring to the broad cultural concept affirming items, behaviors, and visual styles that evoke childlike cuteness, sweetness, and charm; qualities that "make one's heart flutter." While often associated in the West with specific media such as "chibi" (the stylized, small-bodied caricature popular in manga/anime), the concept of kawaii in Japan is far broader and more complex. It has diversified significantly over the decades to encompass concepts far removed from simple cuteness. For example, the aesthetic has spawned hybrid styles such as Gurokawa ("creepy cute") and Erokawa ("erotic cute"), which combine cuteness with darker or adult themes. The kawaii aesthetic is a staple in J-fashion, and many of its derivative sub-aesthetics originate from the Harajuku neighborhood and surrounding Shibuya district of Tokyo.

In ancient Japanese, the words “kawayushi” (かはゆし) and “kaohayushi” (かほはゆし) were used. Different to the nowadays "kawaii", they were associated with a negative image, referring to something "so pitiable one can't stand it". Later on, those words were replaced by "kawaii" and started to take on a positive strength, instead of being seen as a weakness. However, before the term became used the way it is now, it was mainly used by men to objectify women, and during the 60s, it was very common to be catcalled "Kawaiko-chan" (かわい子ちゃん), which is similar to the English "cutie". Later on, the meaning of "kawaii" changed once again when women started to use it to describe everything that is just like them: cute.

In the 70s, the number of people who use the term "kawaii" exploded, resulting in the birth of kawaii culture. The Japanese word "kawaii", which previously was just an adjective, has come to have symbolic value. During that time, the company Sanrio gave birth to Hello Kitty, which soon would become one of the most iconic "kawaii" characters in history. Beyond that, "non-standard girlish script" (変体少女文字) was introduced as the typeface in 1974, and this overly cute writing style became so popular among high school girls, teachers started to have issues reading their homework. Another change of that time was among girl's manga magazines. Previously, they mostly came with posters and stickers of popular boy groups, similar to western girl's magazines, but in 1975 this changed to "kawaii" stationary goods with characters from the mangas printed on them.

In 1982, the magazine "Olive" (オリーブ) was launched by Heibon Publishing (now Magazine House) and gave birth to the first wave of "kawaii revolution" (かわいい革命) as well as "otome" culture. The fans of the magazine dolled themself up in ribbons and frills, lace, floral prints, and other girly styles. Popular with those girls that idolized its style were brands that gave off a fairytale-like feel, such as Pink House by designer Isao Kaneko. The designer did not hesitate spreading the new meaning of "kawaii" as "by women for women" which is precisely why the brand has been considered a leader of spreading kawaii culture ever since. Its followers would collect things that appealed to their sense of cuteness and mix them, expressing their individuality, and this is would evolve into what is referred to as Harajuku or kawaii fashion nowadays.

Kawaii visuals are in a range of colors, but are most commonly associated with pastels , with white as a neutral and pink as the most popular color. However, this is not necessary in all of the aesthetic's visuals, as different examples show that this is not the case; for example, neon with Decora and black with some Sanrio characters. Lighting is always bright, with few to no shadows. Photo-editing is highly utilized in kawaii, as people often add additional stickers and sparkles, enlarge their eyes, and smoothen the photo to look more maximalist and hyper-cute.

Sweets are a common visual motif in kawaii. These can include cakes, macaroons, flan, cotton candy, iced cookies, ice creams, parfaits, and even sweet drinks like ramune or boba. These sweets are done in the Japanese style with specific references to the culture, such as having the food shaped like certain characters, elaborate whipped cream decorations, having desserts in pastel/bright colors, etc., as opposed to Western sweets. Decorations are mandatory, with multiple textures and colors present via sprinkles, drawn-on icing, etc. Strawberries are an incredibly common motif due to repeated use in early artworks and merchandise. Additionally, savory foods may appear in the form of bento boxes with food shaped as different characters. Nature-inspired motifs, such as skies, flowers, and small critters, are also very commonplace in form of minimalistic drawn stars, clouds, rainbows, butterflies, and cherry blossoms.

Anthropomorphic illustrated characters, are the most unique and recognizable feature of the aesthetic. The most popular characters originate from the Japanese company Sanrio, which created Hello Kitty, Cinnamon Roll, My Melody, and more that can be viewed here . Another popular company would be San-X, with characters like Rilakkuma, Sumikko Gurashi, Sentimental Circus, Mamegoma and more, which can be viewed here . Other examples include Care Bears, Moomins, Pusheen, and different Animal Crossing characters like Isabelle and Tom Nook, and different Pokémon such as Pikachu and Eevee. There are multiple commonalities between these kawaii characters; many of them are simple in design, with features that are simultaneously distinct enough to be different from other competing characters, but also following the guidelines in character design that make characters look friendly and child-like. These include round bases for bodies, large eyes and heads with small arms, and a lack of intense shadow and angularity. These characters' immense popularity allows them to easily be marketed as merchandise, with a variety of stationery, home goods, clothing, and even large vehicles such as airplanes.

Human characters could also be classified as kawaii if they are innocent and childlike. These are called Moe, and tend to come from anime and manga, as the trope is from Japanese pop culture. Like the critters, these characters have large eyes, round shapes, and unique colors and outfit designs. Their intense and open displays of emotion are related to people's affection for them, and often appear as either helplessness and/or upbeat cheerfulness. One such character is Hatsune Miku, the most universally recognizable Vocaloid. Gifs and images of these Moe characters often appear in kawaii blogs and websites.
