Born in Chiba Prefecture, HiroshiMiyauchi is pretty much the most profilic actor of {{Toku}} genre. (How prolific? In the KamenRider 40th anniversary and SuperSentai 35th anniversary movies, he portrays two roles ''each'': V3 and Zubat in the former, and Aoranger and Big One in the latter. And that's not counting coming back as DaChief in Ohranger.) While these years he hasn't been seen, he's been in many {{Toku}} shows that [[HeyItsThatGuy you can recognize him easily]] if you do watch some old school ones.

No relationship with HiroshiFujioka (who is more or less his KamenRider equivalent when it comes to {{Memetic Badass}}ery) or [[Creator/{{Nintendo}} Hiroshi Yamauchi]].
