Segata Sanshiro (せがた三四郎 Segata Sanshirō?) is a fictional character created by Sega to advertise the Sega Saturn in Japan between 1997 and 1998. He is a parody of Sugata Sanshiro, a legendary judo fighter from Akira Kurosawa's Sanshiro Sugata. He is also a playable character in Project X Zone 2.


Sanshiro is a Judo master that tracks down and punishes those who do not play the Sega Saturn. His name sounds similar to the phrase "You must play the Sega Saturn!" (セガサターン、シロ! Sega Satān, shiro!?) as well as "Sega Saturn, White" (セガサターン、白 Sega Satān, Shiro?), a reference to the new white color version of the Japanese Sega Saturn which followed the original gray version.

Sanshiro lives as a hermit high on a mountain, devoting his life to intensive Sega Saturn training. He trains physically every day by carrying around a giant Sega Saturn on his back and punching buttons on its giant controller, as well as mentally by breaking stacks of blocks with his head. His intense training has resulted in his ability to make people explode twice by throwing them, which he does with ease. He also frequently visits the city to seek out people who are not playing the Sega Saturn, and harshly teaches them a lesson. Sanshiro is a serious man with a firm sense of duty, who believes that playing video games is one of the most treasured activities in life.

The character became very well known in Japan and helped make the Saturn successful in that country. When the CD music single was released, it sold more than 100,000 copies.

When the Saturn was phased out and the Sega Dreamcast released worldwide, Sanshiro's end came in the form of a commercial involving a missile directed at the Tokyo headquarters of SEGA, implied to be launched by Sony and Nintendo. Sanshiro heroically jumps off the roof of the building, onto the missile, deflecting it into the atmosphere while riding it, in which he lives his last few moments chanting out "Sega Saturn Shiro!!" for one last time, and is presumably killed in the subsequent explosion. Shinji Nakae narrates that "Segata Sanshiro will live on in your hearts," followed by a display of the game Segata Sanshirō Shinken Yūgi, a Sega Saturn game in which Sanshiro plays a major role.

His legacy lives on through his son, Sega Shiro. It is later revealed in the 2020 Sega's 60th anniversary commercials that Segata had survived the rocket explosion and has been watching Shiro grow from afar, waiting for the day his son becomes worthy enough to protect Sega's legacy as Segata did in the past.

Other Appearances[]

Segata appeared in Rent-a-Hero No.1, Sonic the Hedgehog of Archie Comics (In issue 269), and in Sonic and All-Stars Racing Transformed, riding the rocket from the final commercial and carrying a giant Sega Saturn on his back (though he only appears in the final lap of Race of Ages).


Segata's theme is "Sega Saturn, Shiro!"


Sega Saturn, Shiro!

Sega Saturn, Shiro!

Crosspedia Entry[]

A powerful man who has mastered the way of play.

To the feckless youth of today, bored by their ephemeral existence, he strives to communicate the value of devoting oneself tirelessly to a task, using himself as the ultimate example. "Segata" is his surname, but everyone always says it first.

Blessed with superhuman reflexes, he is an expert in many martial arts, his many honors including a 1st degree black belt in karate, a 3rd degree black belt in judo, and a 4th degree black belt in battoudo.

He can also break ten tiles with his head, return a baseball from a pitching machine with a kick, and fillet a fish like an expert.

The quintessential man among men, he has a supernatural power called "Dragon Force" that allows him to make identical copies of himself.

You must play the Sega Saturn!


Enemy Unit[]

  • The Path of Play (Special): Segata begins by flying forward with a jump kick, followed by a surprisingly powerful roundhouse kick, sending his opponent flying away. Segata then uses his impossible speed to dash forward ahead of his enemy as they continue soaring. Just when the foe is about to hit the ground, he grabs them, throws them against the screen, and they bounce off, exploding upon hitting the ground, whilst Segata walks away from the blast.
  • Dragon Force (MA): As an aura exudes from him, Segata summons an army of duplicates of himself to charge forward, tearing his enemies apart. Said enemies then get sent into the air, and fall into a perfect pile in front of him. Sanshiro finishes them off by performing a downward headbutt, damaging all of them.
