Hatsune Miku

Hatsune Miku (初音ミク Hatsune Miku) is a singing synthesizer application and its personification, both developed by Crypton Future Media. She is the first in line of Crypton's "Character Vocal Series" and is powered by Yamaha Corporation's Vocaloid 2 synthesizing technology.

The program, and by extension, the character Hatsune Miku, becomes famous throughout Nico Nico Douga as a performer of many fan-based compositions, and eventually becomes a major icon in Japanese pop culture.
