Hiro Nakamura is Heroes main character (If you are not watching Heroes, what are you waiting for!), he has a sword that belonged to someone called “Takezo Kensei”. The cool thing is “Takezo Kensei” is not a fiction character, he was a real samurai, in fact he is probably the most “famous” samurai ever. If I tell you that “Miyamoto Musashi” is his usual name you will probably know him, but “Takezo Kensei” is how he is called in Heroes. “Takezo” is an alternative reading of Musashi 武蔵, and “Kensei” is the highest rank a samurai can hold, only legendary samurais are considered “Kensei”. “Kensei” could be translated as “Heroe”.
He is the historical Miyamoto Musashi, known in Heroes fiction TV series as Takezo Kensei.
Miyamoto Musashi/Takezo Kensei fought at Sekigahara, one of the most important battles in Japanese history, he survived more than 60 duels “one vs one” during his 61 years of life, he created many fighting styles and he finished his days writing books. He is considered the best swordsman ever.
Spoilers warning! Spoilers warning!
Miyamoto Musashi appears many times in Heroes, in the museum when they are trying to steal a katana, when Hiro talks about Takezo Kensei, and we can even see the “real” Takezo Kensei at the second season’s beginning when Hiro travels back in time to 1671. Another interesting detail that future Hiro Nakamura has the same air style as Miyamoto Musashi .
Miyamoto Musashi air style is very similar to future Hiro Nakamura.
The katana in the TV series is an invention, in the real history Miyamoto Musashi never had a favorite sword. In the katana from Heroes TV series there is a symbol (This symbol can be seen many times in many places). As Ando explains in one episode, the symbol can be created combining two Japanese characters: sai 才 (Great talent, genius), and yo 与(One of the meanings of this kanjis is “godsend”). If you put together these two kanji characters you obtain the symbol from Hiro’s katana that belonged to “Takezo Kensei”:
Are Hiro Nakamura and his father descendants from Miyamoto Musashi/Takezo Kensei? Are Heroes main characters Gods? Is Heroes a battle between Gods?
If you wanna learn more about the real Miyamoto Musashi, I recommend you: Musashi Miyamoto by Eiji Yoshikawa; which is the best book around there. Is huge but I’m sure you will enjoy every line if you are a fan of Japanese culture.
