m-Lab Inc. (Headquarters: Chuo-ku, Tokyo; Representative Director: Shinya Murakami) is pleased to announce the official release of its metaverse mahjong parlor "Metajan" on Wednesday, April 15, 2026. With this release, we will begin offering a new "gifting function" and a "paid plan (980 yen per month)" to further enhance the interaction experience between users and with casts. ## Main Updates of the Official Release - ① Implementation of Gifting Function A "gifting function" has been implemented, allowing users to send their support to casts. This will enhance not only the play experience but also the value of communication. *Gifting is limited to casts (not available between users). - ② Launch of Paid Plan (980 yen per month) The following benefits will be provided to paid members: - Unlimited use of private mahjong table spaces - Ability to invite non-member users - Ability to play matches while enjoying conversations in a private space This will meet the needs of users who "want to play thoroughly with friends" or "want to converse with peace of mind." In the future, paid member-exclusive events and cast appearance projects are also planned to be rolled out sequentially. - ③ Commencement of Cast System Expanding on the popular guest appearances in the open beta version, a new "cast system" will officially begin operation. Various casts will be stationed daily to play matches and interact with users. This creates a mechanism where users can enjoy a different experience each time they enter. - ④ Enhanced Staff Support System From April 1, 2026, a permanent staff system will commence. Even first-time Metajan users can use the service with peace of mind. Both staff and casts are scheduled to be permanently stationed primarily from 20:00 to 23:00. Cast permanent hours may change due to circumstances. ## What is Metaverse Mahjong Parlor "Metajan"? "Metajan" is an online mahjong platform that recreates the experience of "gathering around a mahjong table" itself in a metaverse space. Players can gather around the same table with their avatars and enjoy conversations while playing matches, allowing them to experience the "feeling of playing with people" that is absent in traditional online mahjong. Furthermore, by eliminating automatic notifications for "calls" (鳴き) and "dora," the design allows users to enjoy elements unique to real mahjong, such as overlooking opportunities and strategic bluffs. Through the cast system, we also aim to create a new platform where mahjong players and streamers can thrive. ## Features of Metajan - No app required, can join immediately from a browser - Realistic mahjong experience with conversation during matches - Authentic match design without call navigation - Community formation through interaction between casts and users - Metaverse space capable of simultaneous connection for up to 1,000 people ## How to Play This service can be used without account registration.
