In the iconic opening sequence of the anime series Pokémon, the titular pocket monsters are shown in various states of activity, including when they 'evolve'. As the little electric mouse Pikachu grows into Raichu, a bright flash of light accompanies the physical transformation. The moment is accompanied by a burst of 'pikapika' to emphasize the gleaming effect.

In the popular video game Animal Crossing: New Horizons, players can customize their islands with various decorations. Certain items, like the 'Festive Tree' during the winter holiday season, will display a 'pikapika' effect indicating that they are sparkling. Players use the word 'pikapika' to express their delight at the appearance of their virtual surroundings when lit up.

In the 2012 J-Pop song, "Heavy Rotation" by AKB48, the lyrics reference the excitement many feel towards something shining. The phrase "pikapika" is used in the chorus to describe the visual appeal of an adored object, like a newly bought dress. The song's energetic performance and catchy tune further amplify the effect desired.

'Pikapika' has achieved significant cultural traction because of its versatility and evocative nature. The word conveys a sense of brightness, cleanliness, and appeal. It is easily understandable, even for those who are not fluent in Japanese, due to its onomatopoeic structure. The repetition of the sound 'pika' itself mimics the flash of light and visual effect.

Its use in children’s programs such as Pokémon helped to solidify its place. The word became associated with exciting events and desirable items, thus ensuring it would become adopted by younger audiences. The application of "pikapika" isn't limited to a formal context or subject. The word has evolved to describe things of value, like trophies, accomplishments and things of perceived material value. Additionally, in many online communities, 'pikapika' can be used as slang to describe something exceptionally attractive or shiny. This versatility has allowed it to transcend these initial contexts and permeate everyday language, making it a familiar word.
