For those wanting to rewatch or catch up on previous seasons of "Tokyo Revengers" before Season 3, doing so is rather complicated as they unfortunately can't all be streamed on one singular platform. Viewers will need access to at least two separate streaming services to watch the first two seasons.
Season 1 of "Tokyo Revengers" is a bit easier to get. It's on Crunchyroll, which has it streaming in both English subtitled and English dubbed formats. However, the first season of the anime is also available on Max, as part of the service's curated selection of anime content. Season 2, on the other hand, is on just one streaming service: Hulu. That means a Hulu subscription is required to stream not just Season 3, but Season 2 as well, making it absolutely necessary for anyone who wants to watch past the initial installment.
To date, "Tokyo Revengers" has not been made available for digital purchase on storefronts like Amazon Prime Video or the iTunes stores. As such, the only way to watch the full series is to get a subscription to either Crunchyroll or Max, and then a subscription to Hulu.
