During the “Gintama Haru Matsuri (Ka)”, Yoichi Fujita who is one of the main directors addressed the issue of whether the anime would be continuing at a later date after ending last week at 201 episodes. His answer went along the lines of, “The creator [Hideaki] Sorachi didn’t come today, and I think he’s undoubtedly writing new story scripts. Once we have gathered the stock material, we staff members want to work on it again.”
The other main director, Shinji Takamatsu reassured the crowd by telling them that the Gintama anime is definitely not over yet.
So it should start up again once the manga has created more material to choose from.
