History Trivia / TaiyoNiHoero

** Tetsuya Watari, Ishihara's HeterosexualLifePartner joined the cast for the final episodes. He earlier appeared in ''Daitokai'' and ''Seibu Keisatsu'' with Ishihara, while Western fans remember him more in Nikkatsu's action films ''Film/TokyoDrifter'', the ''Outlaw Gangster VIP'' series, and the [[VideoGame/{{Yakuza}} Yakuza games]].

* TheCastShowoff: Doc is frequently seen skiing if the episode takes place at a snowy mountain. That's because Masaki Kanda is fairly good at skiing; any time you see Doc doing so, it's likely Kanda actually doing so.

** The appearance of Creator/KenWatanabe in Episode 574 was his on-screen rehearsal for a future role as a regular (see the next entry), but for whatever reason, the producers did not decide to push through with casting him.

** The 600th episode's name? "Shinjuku Case No.600." How creative.

* {{Improv}}: In the SeriesFinale, [[https://www.youtube.com/watch?v=wsu3Haq28qA Boss has a monologue with the sister of a man who has kidnapped Blues and convinces her to give up the location of her brother.]] This was completely unscripted and was meant to be Yujiro Ishihara's last tribute to his fans, as well as a summation of his own life and personal philosophy. These days it is well-remembered by fans of the show as "Ishihara's Five Minutes".

** Masaya Oki (Scotch) had a short first run on the show as he was in high demand as an actor. He returned to the show in 1979 because a show he was in at the time didn't do well in the ratings, and due to Jun Miyauchi's departure (and as it happened, Akira Onodera's upcoming farewell). He was brought back to help boost the ratings and stuck around Episode 493, where [[spoiler: he got KilledOffForReal.]]

** Tappei Shimokawa said he once suggested two stories regarding Pops. The first had him act as an escort for a criminal and get killed off; the other was centered on the birth of his grandchildren. In another interview, he also mentioned proposing that Pops be killed off by engaging in a gun duel with bank robbers. Oddly enough, the latter two tie in rather neatly during his last regular appearance on the show as he tries to arrest Rocky's murderer, who robbed a safe and killed the owner (and left behind kids of his own).

* SpecialEffectsFailure: The episode "Balloon Bomb" has the titular weapon's flight get poorly-rendered on a [[DrivingADesk rear-projection screen]].

* McLeaned: As with the show's infamous habit of KilledOffForReal, this was the main reason for the latter trope being enacted by the producers. Not that it wasn't necessarily a bad thing however - character deaths were considered a sort of "graduation" ceremony by the cast and crew. Behind-the-scenes footage and pictures even show the departing cast members being congratulated by the crew following the filming of their death scenes.
