A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

Thunder Dragon Bay; gives people +1F when you perform a thunder action. I don't see any cards with [Thunder Battle:] so im assuming that cards with the thunder keyword are considered Thunder actions. Do battle actions on personalities with the Thunder keyword count as a thunder action? Or do battle actions on cards performed by personalities with the Thunder keyword count?
Also, if a personality at another battlefield, has a reaction can it be used?
Hachigoro, if i control no units at the battlefield can i still use his battle action cause it would bring him into play for the rule of presence?

Here are the keyword rules for abilities: http://rules.l5r.com/CE_Card_features#Abilities
Just for giggles, I'm going to replace all if the examples, which use "Ninja" in the online wiki, with "Thunder".
"Ability keywords: An ability has any boldface keywords that appear immediately before its designator. "Example: “Thunder Battle:” In this case, the ability is a Thunder ability.
"A card has any keywords of its abilities. "Example: A card with the ability “Thunder Battle:” has the Thunder keyword.
"An ability also has any keywords that are on its card. "Example: An ability on a Thunder card is a Thunder ability.
"EXCEPTION: Keywords that a card only has from one of its abilities are not given to other abilities on the card. "Example: A Thunder ability on a card does not by itself give Thunder to any other abilities on that card.
Each word in an ability’s own keywords is a separate keyword. Example: A “Bushido Virtue” ability is a Bushido ability and a Virtue ability."
