Mutaito's Training Grounds is the highland full of strong enemies where Master Mutaito trained himself. It is located southwest of the Divine Crossing and northeast of the Northern Wastelands. Tien Shinhan and Chiaotzu were training there right before the arrival of the Saiyans on Earth.
In the Nintendo DS game Dragon Ball Z: Attack of the Saiyans, Master Shen kidnaps Chiaotzu and takes him there before the arrival of the Saiyans, to exact revenge on Tien Shinhan for humiliating him and his brother at the 23rd World Martial Arts Tournament. Tien, Yamcha, and, Krillin soon track them down, and are forced to fight Shen's secret weapon: the Tao Pai Pai EX. After defeating the robot, Tien threatens Shen into leaving him alone forever.
- One of the grounds there in Attack of the Saiyans, which can only be accessed by a suspension bridge, looks very similar to the Dead Field.
