The voice sampled for her was confirmed to be that of singer Kyounosuke Yoshitate.[1] She is illustrated byokama, a Japanese manga artist and illustrator.[2] She later released onVocaloid 4 andSynthesizer V Studio 2.
She was originally designed by Sanrio forComiket in 2009.[3]
In October 2010, Iroha was released for Vocaloid 2 with two demo songs, her appearance, and her name. Her voice provider was initially unknown. However, it was said that the voice provider was a female professional singer who passed the audition test set by AH-Software.[4]
Nekomura was one of the vocals set to be released by e-capsule.[5]
Silhouettes for Nekomura Iroha, along with the other vocals by AHS, were revealed on a poster on November 6, 2014, however, at the time, it was unconfirmed what they were for.[6] On November 20, it was confirmed in the livestream forVocaloid 4 that they all, with the exception ofTohoku Zunko, will be receiving Vocaloid 4 updates. On May 14, AH-Software confirmed that Iroha would have a Natural and a Soft voicebank, which allows her to use Cross synthesis and she would release on June 18, 2015. It was also revealed that the design shown in April was for her Soft voicebank. Iroha's Natural and Soft voicebanks would be available for purchase individually or together, and a starter pack version would also be offered.[7]
In another interview, Tomohide Ogata expressed a desire to produce English versions of their Vocals. However, the project would be too complex. He went on to explain that because all of their providers are Japanese, they would rather seek English speakers of a similar voice to the Japanese versions from the United States and United Kingdom.[8]
On May 14, 2025, AHS announced that Nekomura Iroha would be receiving aSynthesizer V Studio 2 voice bank, which would eventually release on October 22 of the same year.[9][10] Despite coming out to the public as being atrans man andhormone replacement therapy changing his voice, the original voice provider Kyounosuke Yoshitate reprised his role as Nekomura Iroha.[11]
Iroha is canonically a "Kittyler", someone who loves the Sanrio characterHello Kitty. She joined theHello Kitty to Issho! Project in early August 2010.[12][13] According to her official profile on theHello Kitty to Issho! page, she is interested inHello Kitty and wants to become a "Platinum Kitty".[14] Also a story about how she became a Kittyler was included.
The speakers encasing her hands are called Dynamic-Phonon Busters. The other set of speakers are called Chorus-speakers. Each of these move around, supporting her. The floating microphone collects her voice, and Announce Booth, which is on her head, works as an amplifier that divides sounds into three classes for the speakers, according to ranges: the sound frequencies fortweeters,mid-range speakers andwoofers.[15]
