Voltage, Inc. is a Japanese developer of Romance Game Visual Novels for mobile phones. The company originated in 1999, based in Tokyo, and began to expand to English-speaking audiences in 2011, releasing English-language versions of their games through the Apple Store and Google Play. Expanded versions of several of their games were previously released through GREE, a social gaming network which provides the games Free-to-Play on a limited daily basis with the option of further advancement via Microtransactions. Support for the GREE versions of the games ceased in 2014, replaced by the similar free-to-play/social media "PARTY" versions of several games.
Voltage's American subsidiary, Voltage Entertainment USA, was formed to market adaptations of existing Voltage, Inc. games which have been heavily localized to appeal to Western audiences, including replacing the anime-style character sprites and CGs with new artwork in a more Western style. Beginning in 2013 with Speakeasy Tonight, however, the subsidiary began producing original games marketed directly to their English-speaking audience.
In 2017, both arms of Voltage shifted from releasing titles as individual apps to each division using a single app as an interface through which multiple titles can be accessed. Earlier Voltage Inc and Voltage USA titles were gradually shifted into these two library apps, respectively titled Love 365 and Lovestruck, and new titles starting with Voltage Inc's Rose in the Embers and Voltage USA's Love & Legends are exclusively available through them. The free-to-play "PARTY" apps remain available separately, and two titles with unique gameplay (Liar! Uncover the Truth and Ayakashi: Romance Reborn) have since been released as standalone apps.
Voltage has also ventured into AR apps featuring simulations of their popular characters for players to interact and take photos with. The first of these was Let's Snuggle! AR in 2017, followed by apps featuring individual characters from their various romance games.
In late 2021, it was announced that the USA division would be shutting down.
