The previously revealed Japanese cast includes Nobunaga Shimazaki as Baki, which is a change from when Masami Kikuchi voiced him in the previous anime series.
The original work, Grappler Baki, began back in 1991 and ran for 42 volumes through 1999 as done by Keisuke Itagaki.
That includes Houchu Ohtsuka as Biscuit Oliva and Kenta Miyake as Jack Hammer.
