The Fountain of Strength was the source of power for Yodoshi and the place where Gabrielle had to place Xena's ashes to bring her back to life (although couldn't). Xena was required to drink from it and gain enough strength to defeat Yodoshi. It is located atop Mount Fuji in Jappa, the same place where Xena killed Yodoshi and Gabrielle killed Morimoto.
