The series page doesn’t list yet what language options will be available for it beyond the Japanese with English subtitles.
That’s now been set as Netflix US has revealed a December 18th, 2018 debut for the series.
The original work, Grappler Baki, began back in 1991 and ran for 42 volumes through 1999 as done by Keisuke Itagaki.
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.
