Where does the Slam Dunk anime end in the manga?

The anime's last episode, broadcast March 23, 1996, ends with Shohoku leaving Kanagawa for the Inter High. Everything the manga is most famous for, the Toyotama game and the Sannoh game, happens after that platform scene and was never animated in the series.

The clean continuation point is chapter 198, the start of the national tournament, found in volume 22 of the original 31-volume tankobon. The anime's closing episodes adapt material up to roughly chapter 197 with original content woven in, including the combined-team practice game, so chapter 198 is where a viewer becomes purely a reader with no overlap to unlearn.

This is the single most-asked navigation question in the fandom, and the shelf answer is simple: the anime is the road to the tournament, the manga's last ten volumes are the tournament, and the 2022 film covers the final game from inside Miyagi's head.
