>> man in brown hat: yaya! >> james: so he has a female student here tonight. this is yaya.first started karate, i didn't know this world. and now i'm learning karate as in the performance and also life. everything is all about love. and karate is showing you if you have this kind of power and the ability to protect yourself, your family, you can be really kind. that's about okinawa i think. okinawan people i think always have this love to everybody. >> anthony: when i first went up this river, i was sick with love. the bad kind. the fist around your heart kind. i ran far, but there was no escaping it. it followed me up river all the way. that was ten long years ago. a previous episode of a previous series in a previous life. yet, here i am again.
