The massively multiplayer online role-playing game will receive updates every ten weeks, with additional quests releasing for the next ten years, reports Andriasang.
Producer Yosuke Saito confirmed the ten-week update plan on Twitter, as well as the addition of weekly story quests, but has never previously put a time frame on content support.
The news comes after the game's Wii launch in Japan. A Wii U version is also planned, featuring improved visuals and cross-platform compatibility.
The game's 2011 announcement caused Square Enix stock prices to fall. Fans were reportedly frustrated with the news that Dragon Quest X was an online multiplayer game with usage fees.
Recent titles such as Dragon Quest VII and Dragon Quest VIII have appeared on the PlayStation and PlayStation 2.
Dragon Quest IX: Sentinels of the Starry Skies, meanwhile, was released on Nintendo DS in 2010.
