Many people claim to have spotted the huge creature in the Himalayas in Nepal.
Rumours about the yeti, also known as the abominable snowman, have been around for years.
No proof
But there's still no proof he exists.
Now a 14-strong team of Japanese explorers have set out to track yeti down once and for all.
'I'll shake hands with him'
Team leader Yoshiteru Takahashi reckons he's seen yeti's footsteps before, and he's definitely real.
"I'll take pictures and shake hands if I meet him," he said. "But we will not capture it."
