Tohoku Zunko was released on September 28, 2012 as a VOICEROID+ and plans for her VOCALOID version began after a successful Anipipo campaign.
On May 16, 2013, AH-Software announced that she would become a VOICEROID+. She was going to be recorded as a VOCALOID in August or September 2013 and was slated for a late 2013/early 2014 release.
In December, a tweet confirmed that her deadline was still uncertain.
On April 26, it was tweeted that Zunko's voicebank was complete. She was announced to be released on June 5 that year and a demo was released along with Zunko's official VOCALOID website. Zunko would come with a starter pack as well as Music Maker MX2.
AH-Software released Zunko as a VOICEROID+ voicebank first. VOICEROID allowed several tones of vocals showing different emotions. Zunko had several new features compared to previous VOICEROIDs: she had the ability to adjust strength of intonation, as well as the ability to insert pauses directly into the tuning screen. Users could also directly use ruby pronunciation markers in the text. It also read text up to 4 times fast and can output 22.1 kHz sample-rate audio files. However, it was intended for speech rather than singing. Despite this, VOICEROID offered the chance for users to make rap songs easier or use her VOICEROID in conjunction with her VOCALOID voicebank, allowing for talking during songs.
In 2015, most of the VOICEROID and VOICEROID+ lineup were upgraded to VOICEROID+ ex, including Zunko.
ExVoice contained additional samples for Zunko. This includeed samples for laughter, giggling, weeping, etc. Zunko's ExVoice also includeed samples of the Tohoku landmarks and other things related to Tohoku. Since release, the software was updated to add more samples to the package. Users could log onto the AH-Software website to retrieve the additional samples if they had the old version. More updates on this extension are planned in the future.
