VY1 (codenamed: MIZKI) is a Japanese VOCALOID originally developed and distributed by Bplats, Inc., under the YAMAHA Corporation. Her VOCALOID3 and VOCALOID4 updates were developed and distributed by the YAMAHA Corporation. VY1 was initially released in September 2010 for the VOCALOID2 engine. There has since been a second installment developed for the VOCALOID3 engine and dubbed VY1v3. Both products are released in deluxe and standard editions. In December 2014, a third installment was developed for the VOCALOID4 engine and was dubbed VY1v4. A fourth installment was developed for the VOCALOID5 engine in July 2018.

The voice provider for VY1 has never been revealed.


VY1, along with its partner vocal VY2, is designed to head YAMAHA based products. VY1 has been released for more versions of the VOCALOID engine than any other voicebank, including VOCALOID first, iVocaloid, and VOCALOID EDUCATION.


The acronym for VY1 is "VOCALOID YAMAHA 1".[2]

The original VY1 codename for "MIZKI" is a reference to hanamizuki.[3] "Mizki" is often used in error to refer to the VOCALOID or voice by fans of the software. A similar situation same can also occur for VY2 with its codename of "YUMA". Vocadol uses the codename, however, the game's content is considered "non-canon".


Unlike past Japanese VOCALOIDs, VY1, along with the voicebank's partner VY2, has never had an official avatar established for it, with the aim of allowing for creative freedom that other VOCALOIDs do not. The character of the VOCALOID was intended to be the producer themselves rather than the product. As highlighted by VY1v4, because of VY1 being avatarless, there is no product-image guidelines attached to the products using its voice and as a consequence, no avatar-based restrictions.[4] 'It' also has no official gender, though the vocal is "female". The placeholder image for VY1 is of a fan and pin, which are both forms of "Kanzashi", a type of traditional Japanese flower-based hair ornements.[5]

The refined version of the character "Kobushi Kiku" from the VesFes contest has been used as a concept for VY1, but has not been established as its official avatar. Other designs that were used included one for the eVY1 module and a second which was used in the Vocadol game. 9 more concepts were originally shown on her release date CD feat. VY1. A total of 12 designs have been used so far to represent VY1's vocal.

Due to the professional design of VY1, the vocal often appears in apps and equipment that involve derivative products produced by YAMAHA either on its own or with VY2.

  • VY1 voiced VOCALO Revolution's introduction and credits, with CUL being the mascot character. Consequently, many fans have confused VY1 and CUL as being the same VOCALOID. Later, CUL herself was announced to be released for VOCALOID3. VY1 and CUL (VOCALOID) have no relation whatsoever for VY1 only provides voices for VOCALO Revolution's videos.


VY1's character status

VY1 was first announced during the time when the focus was on Lily, and comparisons between the reaction in Japan towards Lily and VY1 have been noted and often brought up. Whereas Lily had many songs upon her release, VY1 was apparently slow to gain popularity. Due to its nature, some producers felt it was unemphatic and impersonal.[6]

However over time, VY1's biggest hits in Nico Nico Douga were to come from 'new' producers who had never uploaded work using 'VOCALOID' before.

The song Cyber Thunder Cider reached the 1 million mark on Nico Video.


VY1, and its following vocal "VY2", were developed to head official YAMAHA products. Since their release, the majority of VOCALOID related products produced by YAMAHA included VY1 as one or the initial vocal heading the software. Its large number of releases have over time seen it grow in popularity and is among the most popular and common VOCALOID.


An independent search on Nico Nico Douga revealed that most VOCALOIDs had less than 1,000 videos uploaded on Nico Nico Douga in 2011 between July 1st and December 15th, with VY1 falling into that category as well.[7]
