Grand Sensei Dareth's Mojo Dojo

Grand Sensei Dareth's Mojo Dojo is a dojo in Ninjago City that is run by Grand Sensei Dareth, a self-proclaimed master of Karate. He normally teaches a small group of young students, but his dojo was also used by the Ninja to teach Lloyd Garmadon Spinjitzu and his power.

While the Ninja sailed to the Dark Island to confront the Stone Army, the dojo was used as a place of refuge against potential attacks for the citizens of the city. Following the final battle, Dareth moved to Sensei Wu's Academy with the other ninja, presumably abandoning the dojo.

Pirates Vs. Ninja
The Ninja came to the dojo looking for a place to train Lloyd. Dareth agreed to allow them to train there under the condition that one of them bested him in a fight, which Kai did with ease. As Lloyd was training, he persistently tried to outdo him but succeeded in doing little other than humiliating himself.

Ninjaball Run
The dojo was going to be destroyed by a company called Darnagom Enterprises (which was actually a fake corporation created by Lord Garmadon) unless Dareth could pay $50,000. Dareth was despondent as he had no money, but Nya informed the Ninja about the Ninjaball Run, a race with a $100,000 cash prize. Lloyd and the Ninja entered the competition and won, saving the dojo.

The Day Ninjago Stood Still
When a Stone Warrior entered the dojo and attempted to attack Dareth's students, he tried to defend them with weapons in the dojo. Unfortunately, Dareth's attacks had no effect on the indestructible soldier, forcing him and his students to flee.

Return of the Overlord
When General Kozu was shot out of Garmatron's cannon, he flew into Ninjago City and crashed through the window of Dareth's dojo. At Dareth's command, his students mobbed the general.

Following the Final Battle
After Lloyd defeated the Overlord, Dareth moved into Sensei Wu's Academy with the other ninja, presumably abandoning the dojo.

Description
The dojo has several punching bags and a back room. It also has a shelf with Dareth's treasured trophies, which he reveals to be fake in the episode Pirates Vs. Ninja.
