The Tree Where Morning Starts
Somewhere in the Tanggu Valley (汤谷 Tānggǔ), in the boiling waters of the eastern ocean, grows a tree so vast that its canopy touches the sky and its roots reach the ocean floor. This is the Fusang Tree (扶桑 Fúsāng) — the cosmic roost where ten suns rest between their turns crossing the sky, and the launchpad for every sunrise the world has ever known.
The Shanhaijing (山海经 Shānhǎi Jīng) describes the Fusang with characteristic matter-of-fact precision: "In the hot water there is the Fusang tree. The ten suns bathe there. It is north of the Black Tooth nation. In the water stands a great tree. Nine suns rest on its lower branches and one sun rests on its upper branch." More on this in Women Warriors of Wuxia: Breaking Boundaries in the Martial World.
The Ten Suns System
In Chinese mythology, the sky does not have one sun — it has ten. These ten suns are the children of Dijun (帝俊 Dìjùn) and Xihe (羲和 Xīhé), the solar goddess. Each day, one sun climbs from the lower branches of the Fusang Tree to its crown and then crosses the sky in a chariot driven by Xihe. At day's end, the sun descends to the Ruomu Tree (若木 Ruòmù) in the far west. The next morning, a different sun takes its turn.
This system ran perfectly for eons — a celestial shift-rotation schedule as organized as any modern workplace. The suns took turns. Xihe managed the schedule. The world received exactly the right amount of light and heat.
Then, one day, all ten suns decided to appear simultaneously. The earth burned. Crops died. Rivers evaporated. And the archer Houyi (后羿 Hòuyì) shot nine of them out of the sky, leaving only the one sun we see today. The Fusang Tree presumably still stands in the eastern ocean, but now it holds only a single tenant where ten once roosted.
The Boiling Sea
The Fusang Tree grows in water described as boiling — the Tanggu, or "hot valley." This detail is not decorative. In Chinese cosmological thinking, heat is the natural byproduct of solar energy. Ten suns resting in the same body of water would produce enough heat to boil the ocean around them.
This is mythology operating with an internal logic that approaches physics. The Shanhaijing's authors did not just imagine ten suns in a tree — they imagined the thermal consequences of ten suns in close proximity. The boiling sea is not a random fantasy. It is a logical deduction from premises that happen to be mythological.
The hot springs and geothermal activity found along the eastern coasts of China and Japan may have contributed to this imagery. Ancient sailors encountering warm ocean currents or volcanic heated waters would have had a ready explanation: they had sailed close to the place where the suns bathe.
World Trees Across Civilizations
The Fusang Tree belongs to a global pattern of World Tree mythology. The Norse Yggdrasil connects nine realms. The Mesoamerican Ceiba tree links the underworld, the earth, and the heavens. The Hindu Ashvattha is the cosmic tree of life.
But the Fusang has a distinctive feature that sets it apart from most World Trees: it is specifically astronomical. While other mythological trees connect abstract spiritual realms, the Fusang is the physical infrastructure of the solar cycle. It does not merely symbolize the connection between heaven and earth — it mechanically enables the sunrise. Remove the Fusang, and the suns have nowhere to roost, nowhere to launch from, and the daily cycle of light and darkness collapses.
This mechanical quality is characteristic of Chinese mythology's approach to the cosmos. Where other traditions treat cosmic phenomena as the whims of gods, the Shanhaijing describes them as systems — complex, interconnected, and functionally dependent on specific cosmic infrastructure.
Fusang and Japan
The word Fusang (扶桑 Fúsāng) became the classical Chinese name for Japan. The connection is straightforward: Japan lies to the east of China, in the direction of the rising sun and the mythological Fusang Tree. By naming Japan "Fusang," the Chinese were locating the island nation within their cosmological framework — Japan was the land at the edge of the world, nearest to the place where morning begins.
Japan itself embraced this solar connection. The Japanese name for their country, Nihon (日本), literally means "origin of the sun." The Rising Sun imagery on the Japanese flag connects to the same symbolic geography: Japan is the land closest to where the sun rises, the terrestrial equivalent of the Fusang Tree.
Whether the Fusang Tree myth was inspired by actual knowledge of lands to the east (including Japan) or whether the myth existed first and was later mapped onto geography is debated by scholars. The Shanhaijing's Fusang predates reliable records of Chinese contact with Japan, suggesting that the myth was cosmological in origin and geographic in application.
The Fusang in Art
The Fusang Tree became a common motif in Chinese art, particularly during the Han dynasty (206 BCE–220 CE). Bronze mirrors, tomb paintings, and silk banners frequently depict the tree with birds (representing the suns) perched in its branches. The Jinwu (金乌 jīnwū), the golden crow that lives inside each sun, is often shown with three legs — the San Zu Wu (三足乌 sānzúwū), one of the most distinctive images in Chinese iconography.
A spectacular bronze "money tree" (摇钱树 yáoqiánshù) excavated from a Han dynasty tomb in Sichuan shows a tree with birds, coins, and mythological figures in its branches — a direct artistic descendant of the Fusang image, blending cosmic mythology with wishes for earthly prosperity.
The Fusang Tree endures because it anchors one of the most fundamental human experiences — sunrise — in a specific image of breathtaking beauty. Every morning, when light breaks the horizon, the myth whispers its ancient explanation: somewhere in the eastern sea, a golden crow has left its perch in a colossal tree, carrying the sun across the sky one more time.
