At Sanrio's booth in Comic Market 78th held from Aug. 13 to 15, 2010, it was announced that AH Software and Sario were developing a new Vocaloid, and a demo song "信濃川(Shinanogawa)" was played at the booth. At this point, the avatar and the name of the Vocaloid was kept secret. See http://vocaloid.blog120.fc2.com/blog-entry-6514.html.

Later, a rough sketch of the avatar was revealed on DTM Magazine October 2010 edition released on September 8th. The edition had a companion DVD including two demo songs "クレプシドラ(Clepsydra)" and "Shinanogawa". The name "Nekomura Iroha" became known to the public on September 16th, because the name was written on an ad of the book "Vocaloidをたのしもう" (Let's enjoy Vocaloid) Vol.5 released on September 23rd. See http://vocaloid.blog120.fc2.com/blog-entry-6706.html. Almost at the same time, AH Software officially revealed the details of the product, the character name "Nekomura Iroha" and Iroha's character design as a Vocaloid.
