The Visual Art’s brand is best known as publisher for the Key label (Kanon, Clannad, Little Busters) but they are actually one of the biggest if not the biggest eroge publisher in existence. They are also based in Osaka and not Tokyo, although I am sure most of their studios are spread across those two regions. They are releasing a book called, ‘All About Visual Arts ~VA20 miracle~’ and they are selling it as the history-of-visual-arts-the-company, containing long interviews with Vava, Hinoue Itaru, Jun Maeda, etc. It’s also got interviews with Tanaka Romeo, Ryukishi07 & other excellent guests. Then an introduction to the various products that they have put out in the past. It even says it’s got the latest information on the Angel Beats Game so obviously fully confirming the game’s existence now (as if anyone doubts that anymore). That character on the left is Saya from Kisaragi Gold Star by Saga Planets.
According to vndb.org, this is a list of all their studios: 13cm, Amedeo, B Works, Bonbee!, Catwalk, Concept, Craftwork, E.G.O., Flady, Frill, Garden, Giant Panda, Hadashi Shoujo, Harvest, Hayashigumi, Image Craft, Iris, Key, Kur-Mar-Ter, KuroCo, Kuuchuu Caricature, Lapis Lazuli,LimeLight, Mana, Moe., Ocelot, Otherwise, PlayM, Ram, Rio, Saga Planets, Sirius, Zero, riffraff, tone work’s.
