There are 11 individual upgrades/secret techniques able to be learned within Okami. Upgrades are either bought or obtained after the fufillment of certain requirements. These upgrades are not required to complete the game, but allow for more powerful moves to be performed and for the acquisition of certain collectables such as stray beads, clovers, and treasures that could not be obtained otherwise.

These technique upgrades cannot be obtained until about halfway through the game, therefore I would avoid this guide if you are still in the early parts and are looking to avoid spoilers.
