End of the battle of Okinawa, Southern point of an island of Okinawa.
It means, a last spot where the battle of Okinawa ended and from this cliff, people jumped to the death lather than captured by US soldiers.
People of Okinawa or even all Japanese people were taught by a government and Military that if you were captured by US soldiers, You'd be tortured and slaughtered or if you are woman you'd be raped and murdered. That is why, Civilians or even Japanese soldiers choose to kill themselves.
How beautiful ocean today...
