In this system, the planet Jupiter is associated with the element of wood (木). Thus, 木曜日 refers to the day associated with the planet Jupiter in the original naming system adopted in Japan. The characters 木 (moku) which means "wood," refers to the Jupiter as the wood-element planet. And the characters 曜日 (youbi) are the "day of the week."
