As of late 2024, Crunchyroll expanded its catalog to include Kochikame —specifically the Kochikame: The Movie (1999) and Kochikame: The Movie 2: The Legend of the Strange Atlas (2003). They also rotate "Best Of" compilations. Unfortunately, you cannot watch all 344 episodes here, but it is the easiest legal way to sample the high-definition movies with official English subtitles.
While the dream of a "Watch All Episodes" button on a mainstream streaming service remains unrealized, Kochikame is worth the effort. The movies and available episodes provide a masterclass in gag manga storytelling. If you are willing to dig through the archives or settle for the movies, you will find one of the most influential comedy anime in history. watch kochikame all episodes
