Going as far back as the Jomon, Yayoi, and Kofun periods, this book examines the significance of constellations in the daily life of farmers, fishermen, sailors, priests, and the ruling classes throughout Japan’s ancient and medieval history. As well as covering the systems of the dominant Japanese people, he also explores the astronomy of the Ainu people of Hokkaido, and of the people of the Ryukyu Islands.
