Under his teachers Roshi and King Kai, Son Goku studies important fighting techniques. On his orange training outfit, he wears the Kame sign, the kanji of Master Roshi, who teaches him the legendary Kamehameha. The symbol means “turtle”.
After he arrives in the afterworld, King Kai becomes his new teacher. He teaches him, among other things, the Kaio-ken and the Genkidama. Goku wears King Kai’s kanji, which translates roughly to “world king”, on the back of his training outfit.

Even if you don’t have an orange tracksuit, you can integrate the two masters’ kanjis into your everyday life. All you need is the Dragon Ball Drinking Glass Kame & Kaio. This large drinking glass can hold up to 400 ml – exactly what you need after a hard day of training. The orange and black colour and the two symbols are in honour of your training under Roshi and King Kai.

Please note that the drinking glass does not possess any Saiyan powers and thus can’t survive the microwave or dishwasher unharmed.
