The fourth season of Haikyu!! known as Haikyu!! To The Top is being done as a two-cour season with the first cour starting back at the beginning of January 2020.
The previous seasons were streamed by Crunchyroll with Sentai Filmworks licensing and releasing it on home video in bilingual form.
The second half was set for a summer 2020 debut originally but our friend the Coronavirus gave that a like and it ended up being delayed.
At the same time, Tsukishima is invited to go to a special rookie select training camp for first-years in Miyagi Prefecture.
