Miku turns nineteen, and the national university joins in

Lazia, 3 September 2026 — Hatsune Miku turned nineteen on 31 August, and among those marking the day was the Mahusetan National University. It is a birthday kept by a great many people, in a great many countries, and it has been for years.

What is being counted is the day she went on sale. Crypton Future Media released her on 31 August 2007 as CV01, the first of its Character Vocal Series: a voicebank for Yamaha’s VOCALOID2 engine, sampled from the voice of the actress Saki Fujita and sold with a drawing of a girl with long turquoise hair. The company gave her a name and an age and left the rest alone.

The rest was done by everybody else. Twenty-two thousand original songs had been written for her by the summer of 2010; a year later the figure being reported was a hundred thousand, and that was fifteen years ago. Most were made at home, by people who are not professional musicians, and given away.

That this could happen was a decision. Crypton put the character out under a licence permitting non-commercial use, so the drawings, the songs and the stories people made with her were theirs to make and theirs to pass on. A company that had sold a voice found that its customers had built a singer, and let them keep her.

She has been performing since 2009, projected onto a screen in front of a live band. In 2014 alone she opened for Lady Gaga, played alongside Bump of Chicken and turned up on American late-night television. The crowds at these concerts are the point of them: they arrive knowing every word of songs written by strangers, and they sing them back.

That is what makes her worth a university’s attention, and it is not really a question about software. It is an audience that made its own singer and has gone on making her: a catalogue with no label behind it, a character who in some measure belongs to everyone who has ever drawn her, and a great many people who know the words.

The university has form for this. Its book club, put to readers on 27 August, came with a shortlist of twenty-two titles running from science fiction to scripture, on the view that what people actually read is worth taking seriously. Marking a birthday kept by the people who sing along with her is of a piece with that.

Readers who would like to wish her a happy birthday in person will not have far to go. MIKU EXPO 2026 EUROPE opens at The O2 in London on 12 November and reaches AFAS Live in Amsterdam on 15 November, before Berlin, Düsseldorf, Paris, Madrid and Lisbon. Nineteen years on, the songs are still arriving; the character is still sixteen, and the people who write for her are not.
