MEIKO VOCALOID1 VOCALOID3 | Piapro Studio | Songs Albums Notable Originals

MEIKO (メイコ) is a Japanese VOCALOID originally developed by Yamaha Corporation and distributed by Crypton Future Media, Inc.. She was one of the 4 known "Project Daisy" vocals. Her VOCALOID3 update was developed and distributed by Crypton Future Media. She was initially released in November 2004 for the first VOCALOID engine. There has since been a second installment developed for the VOCALOID3 engine, dubbed MEIKO V3. Her voice is provided by the Japanese female singer-songwriter, Meiko Haigō (拝郷 メイコ Haigō Meiko).

As of August 31, 2019, there will be no further installments with the VOCALOID program. Instead Crypton is focusing on their own program, Piapro Studio.[1][2]



"MEIKO" comes directly from her voice provider's name, "Meiko Haigō" .

MEIKO's codename was "HANAKO";[3] it likely came from "Hanako Yamada (山田花子)", a placeholder name for female characters, and the Japanese equivalent to "Jane Smith". "Megumi" was also a name considered during her development.[4]

She is often misnamed Sakine Meiko by fans. The name originates from the eponymous derivative character, depicted as herself in her younger days.


MEIKO has no official given age. In Maker Hikoushiki Hatsune Mix she is usually portrayed as a middle-aged woman, however KEI mentioned in a magazine interview that what he depicts in the comic is not official.[5]

Spurred on by the items held by Hatsune Miku and KAITO, it became popular to feature MEIKO with One Cup Ozeki (sake).

MEIKO's original illustration was done by Shogo Washizu, often called わっしー(Wasshi), a former member of Crypton.[6][7] Crypton placed this product on the market with a box art that depicted a female character. This character initially had nothing to do with the singer's image, but her anime-based appearance appealed to a mainstream audience and the software sold well.

This design hid the front of MEIKO's sleeveless jacket, making it difficult to tell what the design looked like. Due to this, there are many different interpretations, including depictions from the official company and accounts.[8]

The Microphone in her original V1 boxart is based on a variant of the Sennheiser MD421 model, one of the most widely popular microphones and was first released in 1960.

Wat described how different the intention of the CV series was to the concept of KAITO and MEIKO during the development of KAITO V3. Consequently, Crypton took a different direction with their updates in comparison to the Appends of Hatsune Miku, Kagamine Rin & Len, and Megurine Luka.

The microphone in MEIKO V3's release is based on the iconic Shure Brothers microphone, the model 55s, Multi-Impedance "Small Unidyne" Dynamic, which was first released in 1951. Her mic is based on the modern "55SH Series II" variant, which is much curvier than the original version.

  • KAITO - A complementary voice bank with masculine vocals.



The original release of both KAITO and herself was noted for their lack of marketing. Aside from a DTM MAGAZINE article, both Japanese Vocals went largely under the radar. MEIKO fared better then KAITO despite this, with the reasons being contributed to the majority readership of DTM Magazine being male, she went on to be one of the more successful of the 5 original VOCALOID vocals. The most noted marketing that was done with MEIKO was that a competition was held in 2006, entries submitted original songs. Prizes were given out and 80% of all entries received a special "signed" version of the VOCALOID MEIKO interface.[9][10] Despite her success, the prospect of MEIKO and KAITO receiving updates being impossible post-VOCALOID and it was expected that Hatsune Miku would take over their roles going into VOCALOID2. There was no plan to update the pair originally. Much of this had to do with the state of the market at the time of VOCALOID.[11]

The overall lack of focus on VOCALOID was still notable. Some focus was given to the older engine, but only after VOCALOID2 had gained popularity, with basics such as tutorials produced where there was once not anything at all.

However, despite this the act of putting a character on the boxart was popular, though the image was not of MEIKO originally. The act of putting a character on the boxart was carried over to following VOCALOIDs to encourage creative activities by individuals, expanding the characters based on each user's individual needs.[12][13][14]

MEIKO's V3 release repeats many aspects of what made the CV series popular, and she was already due a series of "beginners guides" in magazines such as DTM before release.


The following covers the VOCALOID software, for future releases see Piapro Studio releases.

MEIKO - Straight
MEIKO's original release was aimed to be a professional and standard vocalist with no distinct traits.[15] When MEIKO was updated, the voicebank had to be completely re-done with a similar tone to the original, thus some aspects of the vocal have changed in consequential versions. The vocal was also originally a counter-partner to the KAITO "Straight" vocal.
MEIKO - Power
A more powerful version of the "Straight" vocal. Its conveyed tone is similar to the "Power" voicebanks of Kagamine Rin.

Google Trends



MEIKO was positively received and sold well compared to her counterpart KAITO, originally being the most popular of the two. For a long time she was the best selling Crypton Future Media VOCALOID, selling 3,000+ units. This lasted until the release of Hatsune Miku. 3,000+ units was three times the number of sales she needed to sell to be classified as successful.

By 2010, whereas KAITO appeared in the Crypton ranking of their best-selling products, MEIKO had fallen from popularity, receiving the least amount of attention of the Crypton VOCALOIDs. In the same year, MEIKO was ranked as the 7th most popular VOCALOID product they sold and the least popular of Crypton Future Media's own VOCALOIDs.[17] On December 10th, 2011, MEIKO, along with the Kagamines' append, were the only VOCALOID software packages not on the top ten list.

A month after MEIKO V3's release, MEIKO took the number one spot on the charts. This was the first time MEIKO had ever held a spot in the top 10 since the charts began. However, her no.1 spot was short lived, and by April she had dropped to the no.3 spot. This was a much faster fall from no.1 than KAITO V3, who managed to stay in the position for several months after release. Meiko soon fell behind KAITO V3 in popularity, constantly being one or two places behind his package. By August 2014, MEIKO V3 was in 6th spot, while KAITO V3 held the 3rd place position, loosing out only to Hatsune Miku V3 who claimed the no.1 and no.2 spot in the ranking. She also lost out this particular month to the Kagamine Rin & Len VOCALOID2 package, which had temporarily returned to the rankings.

In 2014, Crypton's Sonicwire website reported that MEIKO V3 had been the 3rd most sold VOCALOID product.[18] In 2015 the package came 7th.[19]


Despite the lack of media coverage, MEIKO was better received and more successful than Leon, Lola and Miriam. She was overall the most successful of the VOCALOID products when initially released.[20] It was generally believed that the success of MEIKO was attributed to the reader demographic of the DTM magazine, of which 80% were male. It was also thought to be the reason why Kaito failed.[21]

After revived interest began to occur in her counterpart, KAITO, following Miku's release, MEIKO users also attempted to rekindle her popularity. Consequently, the Japanese fandom has taken great measures to push her voice to its limits. This is demonstrated by the fanmade derivative "Sakine Meiko," which was the result of producers testing MEIKO's capabilities to create a much younger sounding voice. Although this involves heavy investment of time to make such a big adjustment to her vocals, it does highlight the overall potential of VOCALOID era voicebanks, as the same techniques have also from time to time been applied to others of the same software with the same level of results.

MEIKO is generally taken as the 6th most popular "Crypton" VOCALOID, making her the least popular overall. This impacts things such as merchandise and she is the least likely of all the Crypton VOCALOIDS to see merchandise.


MEIKO's success lead to a number of trends that impacted VOCALOID for years to come. This includes style of boxart and favouring of female vocals.


An independent search on Nico Nico Douga revealed that most VOCALOIDs had less than 1,000 videos uploaded to the site in 2011 between July 1st and December 15th. MEIKO, however, did manage to be the 2nd most popular VOCALOID when a mean count was done, with 423 views and 21 mylists.[22]

In 2015, a survey was made based on the popularity of VOCALOIDs on the website Niconico. For the year 2014, MEIKO was the 9th most popular VOCALOID.[23]

  • A Japanese electro-pop artist, Susumu Hirasawa, announced that he used a female VOCALOID in the original soundtrack of "Paprika" by Satoshi Kon on his blog. Since Susumu Hirasawa did not reveal which VOCALOID he used for quite some time, except the fact it was a female, many producers speculated it was MEIKO. However, he later mentioned in a magazine interview that it was LOLA.[24]
  • An old myth within the overseas fandom is that her samples were not from Meiko Haigō, but from a computer that generated samples to sound like her. It is estimated this originates from the fact that the original VOCALOID engine based its results on voice analytic instead of vocal samples.
  • She is the third vocaloid to feature the model 55s microphone in her boxart, the first being Sweet Ann and second being Lily (V2 and V3 releases). This has been one of the most notable models of microphones featured on Vocaloid boxart and is also seen on the boxarts of Cyber Diva and Hiyama Kiyoteru V4 - Rocks.
