Summarized from ComiPo! Manga-Making Program to Get English Release on Anime News Network:
As of 2010-12-15, Manga creator Keiichi Tanaka (Minari no Seishun, Doctor Chichibuyama) was still the Tokyo-based software company Web Technology Com Corporation's General Manager & Solution Sales Division. The company is developing an English-language version of ComiPo!, a program that allows users to create their own manga with pre-created 3D characters and settings. According to the company, even "people who can't draw" can create manga with this software, similar to the way that people who cannot necessarily sing can create vocal songs with the Vocaloid software tools.
