NTT Solmare is a publisher and platform operator with two active strands: MangaPlaza, its digital manga service in the United States, and the Poker Dolls ARG, which it is adapting into a Steam game for 2027.
NTT Solmare is described in the two stories as a publisher and operator based in Osaka. Its main market-facing business in the United States is the digital manga platform MangaPlaza, which passed 1 million registered users at the end of July, five years after launching there. Paying subscribers are about 90 percent female readers, and the platform carries titles from more than 120 publishers. The company also runs the Japanese platform Comic C'moA, and the two services share a marketing and technology team. Manga Mirai, described as a cousin service, is closing and moving its content to MangaPlaza.
Separately, NTT Solmare works in web-native mystery fiction. The company announced on September 15 that its ARG "Poker Dolls" will be adapted into a game for release in 2027 on PC via Steam. The adaptation is a mystery adventure game with a new story, and a video and landing page have been released. The original ARG was released in March 2026 and had passed 2 million page views as of June.
The two strands sit at different points of maturity. MangaPlaza has five years of operation in the U.S. behind it, a stated user figure, and a consolidation move as Manga Mirai's content comes over. The ARG side is newer: an original work from March 2026 that is now being carried into a conventional game format with a different story. The stories do not connect the two businesses beyond shared ownership, and no figures are given for the game adaptation beyond the 2027 release window and the PC via Steam platform.
