Yostar released the domestic version of MahjongSoul on Steam on July 20, 2026, and conducted the first Japanese closed beta test for its upcoming open-world RPG Azur Promilia from July 2 to July 10. The company also raised prices at its official shop and Akihabara store on July 1, citing rising costs.
Yostar's most recent activity centers on two major releases. On July 20, the company launched the domestic version of MahjongSoul on Steam, seven years after the game's original debut. The free-to-play mahjong game, which has over 15 million registered users, allows data transfer from browser and mobile versions but not from the DMM platform. The Steam release opens a new distribution channel for the established title.
Alongside the MahjongSoul launch, Yostar and its partner Manjuu Games held the first Japanese closed beta test for Azur Promilia from July 2 to July 10. The test, available on PC and Android, gave players hands-on access to the open-world RPG, which blends action combat, creature collection, farming, and life simulation. Over 180 creatures called Kibo were available in the beta, along with a three-person party system, parry and dodge mechanics, and a farm building mode. The preview described the game as continuing the studio's signature character-driven appeal, with unapologetic fan service. Full release is planned for PC, iOS, and Android as a free-to-play title, with no date announced.
Yostar also announced a collaboration livestream for Azur Lane and NieR:Automata, set for July 11, featuring voice actress Ayaka Suwa and Yostar staff. On the operations side, the company raised prices at its official online shop and physical Akihabara store on July 1, citing raw material shortages, supply instability, and rising energy costs. The price hike affected merchandise lines across the board.

Yostar released the Japanese domestic version of Mahjong Soul on Steam on July 20, 2026. The free-to-play online mahjong game, developed by Catfood Studio, is now available on the platform after its global Steam version was previously inaccessible from Japan. Players who have been using the browser, iOS, Android, or Windows versions can transfer their play data to the Steam version by logging in with the same method. However, account data from the DMM version cannot be transferred. The Steam version is said to have the same specifications as the Windows version, according to a 2024 comparison chart from the official overseas X account. The Japanese Steam store page first appeared on May 21, and the release came seven years after the game's initial domestic launch in April 2019. The game features ranked matches, friend matches, and tournament modes, and has hosted collaborations with series such as Code Geass, Akagi, Fate/kaleid liner Prisma Illya, and Sword Art Online.
The first CBT for Azur Promilia, the new RPG from the Azur Lane team Manjuu and Yostar, ran July 2-10. The preview highlights the game's unapologetic fan service, with characters ranging from 'small' to 'large' muchi muchi. Combat is action-based with a monster companion system, while a farming mode offers a slower pace. The review notes the game's visual emphasis may distract from storytelling.
Manjuu and Yostar, the team behind Azur Lane, began a closed beta test for their new open-world RPG Azure Promilia on July 2, 2026. The CBT runs for nine days through July 10 on PC, with the full game planned for Windows, iOS, and Android as a free-to-play title. Players explore the continent of Promilia, befriend creatures called Kibo through a Star Link mechanic that requires reducing enemy HP without defeating them, and use them in battle and on a farm. The combat system includes parries, dodges, Just Evades, Evade Counters, and Stance Break mechanics that double damage on staggered enemies. The game features a three-person party system with switchable characters, each with unique attack actions and skills. Over 180 Kibo were available in the CBT, with a Kibo Fight mode that plays like a card game. The beta also includes a farm building system, crafting for weapons and armor, fishing, and a photo mode. The protagonist is a Star Visitor with amnesia, and the story involves a companion named Symphoria and a fairy named Lumie.
Yostar announced a livestream on July 11 at 20:00 JST to commemorate the Azur Lane and NieR:Automata collaboration.
