Can I remove Favor tokens from Kyuden Otomo to pay for the Limited action of Writ of Justice?
Writ of Justice: Will only attach to a Courtier. When it enters play, put Favor tokens on Writ of Justice equal to the Courtier's Personal Honor. Political Limited: Bow this Personality and remove three Favor tokens to bow a Dishonored Personality. Political Limited: Bow this Personality and remove six Favor tokens to destroy a Dishonored Personality.
Kyuden Otomo: You may remove a Favor token from your Stronghold to pay the cost of discarding the Imperial Favor. You may lobby to add a Favor token to your Stronghold.
Political Open: Once per turn: Name a legal Wind you dont control. Remove from the game a Wind you control. Bring the named Wind into play from outside the game.

No. You cannot remove Favor tokens from other Writs of Justice, either.
