Since being certified as the first Santaland outside of Norway by Oslo, the home of Santa Claus, in 1984, this event has been held every year in the spirit of "love, peace, gratitude and service." The Santaland Christmas Market sells food and drinks and distributes hot drinks for free, and the Santaland Sound Festival also features a mini concert by the Hiroo Santaland Jazz School, a high-level performance by the ensemble group "Sora," a husband-and-wife duo from Hiroo Town called "The Marbles," and a mini live performance by "Chima" from Office CUE, making for a spectacular stage lineup.

The climax of the event is the illumination lighting ceremony, where a switch is pressed along with a countdown, causing the trees and facilities in the forest park to light up all at once, creating a fantastic Christmas atmosphere throughout the park. At the end of the ceremony, fireworks are launched, creating large flowers that bloom in the clear late autumn sky.
