Tone Rion (兎眠りおん) is a Japanese VOCALOID developed and distributed 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. In December 2016, Rion's voice provider was confirmed to be's Nemu Yumemi.[3]

Rion was updated to the VOCALOID4 engine in February 2017.[4]


Her brief back-story 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 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.

Tone Rion's character status

Rion was popular upon release with the Vocaloid otaku crowd, although was not the most popular of the VOCALOIDs released in 2011. On December 11, 2013, research shows her as the least popular release for VOCALOID3. She also failed to get any songs in the Nico Nico Douga rankings in the week of her release and has mostly stayed off the ranking since release.


Although Tone Rion received an "SE" release, she was dropped from further developments for VOCALOID3. As a result, she is currently the only "Yamaha" VOCALOID who did not later receive a VOCALOID NEO release.


In 2015 a survey was made based on the popularity of Vocaloids on website Nico Video. For the year 2014, Tone Rion was the 32nd most popular Vocaloid and the 5th least popular Japanese capable vocaloid.[7]
