Tokyo theater company Office Endless is producing a stage adaptation of 2018 DC anime film Batman Ninja, to be performed at Tokyo's Theatre Moliere Shinjuku from October 10 through December 31.
Few other details of the production are known, but an official site for the live action Batman Ninja has been set up, along with a promotional image seen here.
Here's Warner Bros. Animation's official synopsis of the original animated film:
"Batman Ninja takes a journey across the ages as Gorilla Grodd's time displacement machine transports many of Batman's worst enemies to feudal Japan - along with the Dark Knight and a few of his allies. The villains take over the forms of the feudal lords that rule the divided land, with the Joker taking the lead among the warring factions. As his traditional high-tech weaponry is exhausted almost immediately, Batman must rely on his intellect and his allies - including Catwoman and the extended Bat-family - to restore order to the land, and return to present-day Gotham City."
