Take the following as truth: These districts on the west and north sides of Kyoto are home to most of the city's major temples, set within the surrounding greenery and mountains that prompted the Emperor Kammu to select this site for his new capital, Heian-kyo, in 794.
Then the following statement: "The mountains are a reason why the Emperor Kammu chose this site as his new capital." is true, false, or inconclusive?
