Tone Rion (兎眠りおん) is a Japanese VOCALOID developed and distributed by the YAMAHA Corporation,[1][2] and was created in collaboration with Dear Stage (Moe Japan, Co. Ltd.). She was released in December 2011 for the VOCALOID3 engine.

Rion was updated to the VOCALOID4 engine in February 2017.[3]

In December 2016, Rion's voice provider was confirmed to be's Nemu Yumemi.[4]


Her brief backstory states that she is 16 and was born in the year 2095. Rion performs on the "Dear Stage" (ディアステージ) located in future Akihabara set 100 years from the current time. She is based on the idea of "VOCALOID + idol = Vocaloidol" and was the first of the Dear Stage VOCALOID "Vocaloidol" concepts of which 5 vocals were planned. The vocals would come from within Moe Japan's own vocalists.


The kanji for Tone Rion's name means 兎 (bunny/rabbit) and 眠 (sleep), however the phrase itself, "兎眠" (rabbit's sleep), has no significant meaning in Japanese. Though the company does not give any account, Rion's name is believed to be a double pun on the English word Tone and the musical instrument Tenori-on produced by YAMAHA.


The design has the distinct appearance of a 'cooking' maid. However, based upon her background, the design is meant to portray an Akibamaid (秋葉原 メイド), a cosplay girl whose role is that of a waitress rather than a cook.

Her VOCALOID4 design was intended to highlight her link to Yumemi Nemu. This includes a drastic change in color scheming and her physical features such as her hair and eye colors.

Additional informationEdit


Tone Rion is the first VOCALOID to be specifically sold as "Moe" and the first to focus on the otaku-based culture. Rion is also the first to target this particular classification directly with her character design, and her vocal was designed around the commonly considered moe traits of Japanese manga and anime characters.

In VOCALOID4, however, marketing focus was turned to Yumemi Nemu with very little focus being placed on Tone Rion anymore.

Tone Rion's character status

Rion was popular upon release with the VOCALOID otaku crowd, however, she was not the most popular of the VOCALOIDs released in 2011. On December 11, 2013, research showed her as the least popular release for VOCALOID3. She also failed to receive songs in the Nico Nico Douga rankings in the week of her release and had mostly stayed off the ranking.


Although Rion received an "SE" release, she did not receive any further updates until May of 2015, where she was given a VOCALOID NEO update.


In 2015 a survey was made based on the popularity of VOCALOIDs on Nico Video. For 2014, Rion was the 32nd most popular VOCALOID overall and the 5th least popular Japanese capable VOCALOID.[7]
