The first anime version of Chihayafuru came out in 2011, and it was a hit right away.
Chihayafuru’s protagonist, Chihaya Ayase, first appeared in a josei manga that featured the traditional Japanese competitive game of Karuta.
All of Chihayafuru’s seasons have been created by Madhouse Productions. No information about Season 4 of Chihayafuru has been announced by Madhouse.
There has been no official word on a release date as of yet. If the show gets the go-ahead, it might debut in 2022 or 2023.
There are three seasons of the Chihayafuru anime, each with 24–25 episodes. All of the available anime seasons can be viewed in their entirety on Crunchyroll.
– Asami Seto as Chihaya Ayase – Mamoru Miyano as Taichi Mashima – Hoshimasa Hosoya as Arata Wataya – Ai Kayano as Kanade Oe
Since the show has not been greenlit, your prediction that there will be no official trailer has so far proven accurate.
