Ganbare Goemon Wiki

Ganbare Goemon: Jigen Jō no Akumu (がんばれゴエモン 次元城の悪夢? lit. "Ganbare Goemon: The Nightmare of the Dimensional Castle") is a single-episode, twenty-eight minute OVA produced by Konami and AIC studios.

It was originally released in 1991 as part of a campaign to celebrate the 5th anniversary of the Ganbare Goemon series, being distributed as a lottery prize for purchasers of the Super Famicom game Ganbare Goemon: Yukihime Kyūshutsu Emaki (known outside of Japan as The Legend of the Mystical Ninja). It was later distributed as a user gift tie-in for purchasers of Ganbare Goemon 3: Shishijūrokubē no Karakuri Manji Gatame.

It was officially released for purchase in stores on VHS format on March 26, 1993.[1][2]

The OVA stars the voices of Daiki Nakamura as Goemon and Hideyuki Umezu as Ebisumaru, and features segments parodying three other popular Konami franchises: Gradius, Akumajō Dracula and TwinBee.


A humorous action adventure that takes place when a dimensional castle suddenly appears in the outskirts of Edo town. Goemon and Ebisumaru team up once again in order to investigate what's really behind the apparition of this mysterious building. The story takes our heroes in adventures parodying three of Konami's most popular franchises.


One night, a UFO suddenly appears on the sky above the forest at the outskirts of Edo town and crashes into the ground, revealing to be a huge spaceship in the shape of a medieval Japanese castle. The next day, a mysterious little character appears in town, and following his master's orders, kidnaps local belle Omitsu from the tea shop she works at and takes her into the castle. Being informed about this, Goemon and Ebisumaru decide to go investigate.

They break into the castle, where its owner challenges them to dare and reach the top floor where he will be awaiting them; although in order to do so, they'll first have to go through three dimensional floors, each presenting a unique and fantastic adventure. Every time they reach one of these floors, the world around them changes and they transform into the respective protagonists of that world. Their journey takes them through a battle in space, a vampire's castle, and soaring through the sky while riding a fighter aircraft.

They eventually reach the top of the castle, where Omitsu is held captive. Finding themselves cornered, the lord's minion creates an illusion and transforms his master into a very handsome prince, to which Omitsu instantly falls in love with. The happy couple then settle to be married the next day.

At the wedding, the illusion suddenly loses effect and the lord transforms back to his monstrous real form, but the minion quickly recasts the spell and gives his master his good-looks back. The spell doesn't last long, however, and just after a few seconds it once again vanishes away. Horrified by his hideous true form, Omitsu punches the lord in the stomach. The minion once again recasts the spell, but each time the effect lasts less and less time, resulting in Omitsu punching the owner every time he changes back to his real form.

Dimensional castle

The castle resembles a Japanese-style pagoda and has three dimensional floors, making it impossible to reach the top until each one has been cleared. Each one of these floors is based on a Konami game, and once entered, the person becomes a character belonging to that world, allowing them to rewrite its history.

First floor (Gradius)

A space confrontation against a big core while riding the Vic Viper.

Second floor (Akumajō Dracula)

The heroes make their way to the top of the Demon Castle and confront Dracula. However, they find Christine being held prisoner there instead of Omitsu.

Third floor (TwinBee)

The heroes are invited by WinBee (Pastel) to try for that day's highest score. They decide to go to a public bath for a break on the way.
