Sorry, but it is not a kamikaze tanto, just an aikuchi (guardless) tanto. For more info on Japanese military tanto see my page at:

Possibly a kwaikan (ladies sleeve tanto) based on size and simple same' covering. Not ruling out a late tourist knife or even Chinese fake however.
It needs to be seen up close and personal to tell.
