About Us

Malström is a publisher that sells and translates TTRPGs into Japanese, as well as web media distributing varieties of news about TTRPGs at home and abroad. In the Publishing department, we sign contracts with foreign indie designers or companies to sell Japanese versions, mainly in PDFs. The Media Site Division provides various information on new releases and feature articles related to small or mid-scaled indie games in the overseas TTRPG market.

Malström is the Swedish word for Maelstroms. We will continue to connect TTRPG players around the world as a Maelstroms that straddles the ttrpg industry in Japan and the rest of the worlds.
