The replica of Kontengi located to the right of the worship hall is the device for observing the position of the planets and the stars. Since ancient times the movement of the stars has been thought to teach people about directions and the future of the nation. The calendar was made based on the movement of celestial bodies. Furthermore, the calendar was used to divine whether fortune would be good or bad. Kontengi placed in the precinct of Samukawa-jinja Shrine has four dragon statues at its corners in accordance with the legend of dragons supporting heaven.
