How active is a Shiba?

Excuse me, could you elaborate on the activity level of a Shiba Inu? Are they known to be highly energetic and require a lot of exercise, or are they more sedentary and content with shorter walks and play sessions? Additionally, how does their temperament and behavior impact their level of activity, and are there any specific characteristics or habits of Shibas that make them more or less active? I'm interested in understanding the overall activity profile of this breed to ensure that I can provide an adequate environment and routine for a potential Shiba Inu companion.
