Cameos[]

Ashita no Joe[]

Episode 229; When it's finally Gintokis turn in the dating sim tournament, he's conditions are vastly changed to a boxing match! (this scene does also contain dramatic lighting)

Isao Kondo dresses up like Danpei Tange and tries to encourage Gintoki (which he keeps refering as Joe). Gintoki is however every pessimistic about the situation and even says that he has no tomorrow. (sort of reflects how in Ashita Nno Joe, they are fighting for tomorrow)

(Not to mention "Ashita" is tomorrow in japanese duh)

Episode 253; After Gintoki getting replaced as the main character, he gets caught by the yakuza and they torture him. When the boss comands to stop, they see that Gintokis silver hair has turned into white and that he has burned it all to ashes. (Gintokis dialogue is similar to Joes last words)
