The kage is the ultimate leader of a village, and is usually respected and often asked for help. Kage run the village and make executive decisions, especially concerning village funds. The title of kage is an important and often stressful job. Be sure you're up for handling not only your village, but your villagers.
Kages get a (territories / 10)% damage boost when fighting on their home territory.
You can challenge the kage of a village after you've done a few things. These things include:
To get to the challenge link, go to Town Hall, Check Kage, and there will be a challenge link. The challengers of a village will get village walls, so the advantage goes to the attacker. There is also a requirement to keep the title, if you ever drop below the 1.5 x pvp average experience needed to be kage, you will be kicked out and replaced with the AI Kage. This means every kage is required to be active and raid/defend for their village. Also, every kage has a 15 minute period after they claim the seat of kage where it's impossible to be challenged.
Do note: You will lose a minimum of 2500 respect in your village if you fail to win your kage challenge. Thus it recommended that you do ample diplomacy in your village before attempting such a task. [old, confirmation required]
