Seventy-seven-years-old grandma Keiko Wakabayshi isn't nicknamed the "Samurai Granny" for no good reason - she's recently been hired to train Italian soldiers in hand-to-hand combat!
Miss Wakabayshi, who stands exactly 5ft tall, looks tiny compared to her charges who are mostly over 6ft.
But the pensioner is a trained master in an array of martial arts disciplines including jujitsu, jojitso, kenjitso, judo, kendo and karate.
She wipes the floor with soldiers of the Folgore brigade at their barracks in Livorno on a daily basis.

Perhaps the saps they hire ain't real sapphires at fighting?
Anyway, Granny ROCKS.
