So, Conditions. I think they are pretty OK hack for current social system that doesn't require much tinkering with how rest of the game is resolved; basically, this is a "codified way to use Social Skills". This is going to have 3 starting posts, and remember - these are drafts and concepts. Basic outline, not details and finalized product.
Condition
Condition is an effect inflicted upon character due to certain events taking place. Some of them are beneficial, some of them are harmful; and there are some that are mix of both.
Conditions can be aquired by samurai deciding to take certain actions; for example, Samurai proceeding with action that is considered highly dishonorable for his current Honor Rank might end up with a Guilt condition, reflecting how he feels about what he just did. Sometimes, Conditons are simply inflicted upon Samurai due to outside forces; being shamed in public also can, for example, invoke Guilt and Shame. Most reliable way to inflict Conditions upon someone is to use Social Skills - good use of Courtier [Rhetoric] might make someone feel Inspired, while Seduction can turn someone Greedy.
Conditions usually have at least two levels of magnitude - Minor Conditions can evolve into Major Conditions, and sometimes, powerful events or Courtiers can dive directly into Major Conditions.
Conditions bestow negative of positive effects, usually in form of TN or rolled dice modifications. They also usually encourage to roleplay character in certain way - this isn't a compulsion, but character "giving into" the condition can usually gain some kind of benefit; most commonly, regain one point of Void.
Of course, delving into negative condition won't have only positive effects - surrendering to the temptation often will lead into losses of Honor and Glory, while resisting it may reward the character with Honor, Glory, etc. In general, what is rewarded and what is penalized, depends on specific Condition and character's Honor / Glory, as per Condition's description.
Conditions can be resolved - resolving a condition equals to removing it from the character in question. In general, most of Minor Conditions can be resolved by either taking appropriate roleplaying action, making proper Skill Roll and spending a Void Point, or - preferably - both. Most common ways for Samurai to purge their souls are visiting the temple and undergoing ritual purification; meditating upon Bushido or some other important dogma; visiting Geishas; and socializing with friends in informal setting . In general, situations where character isn't forced to wear their face are best suited to removing Minor Conditions. Of course, these aren't the only possible options; in general, anything fitting the Condition and character in question is fair game. After all, while Akodo might recite Bushido 1000 times to forget about his love, Kakita may do the same by immersing himself in duels.
Conditions descriptions also often propose some specific way of resolving them.
Major Conditions are harder to get rid of. They usually take more time to resolve, and "generic roleplaying action" rarely will be sufficient to defeat them. Accompanying Skill Roll is also usually harder. In order to defeat Major Condition, you usually need to take some special action; again, anything major and making sense, accompanied with a successful roll and Void Point expenditure should suffice. Most of the time, characters will try to degrade Major Condition into it's lesser version, and then deal with it permanently; removing Major Conditions outright is quite hard.
