Why Gion Matsuri Exists: Its 869 Origin, Explained (Gozu Tenno & Warding Off Plague)

Why does Gion Matsuri run for the whole of July, and what are those lavish floats for? The answer lies in the festival's birth as a prayer to ward off plague. For dates and access, see the Gion Matsuri 2026 complete guide. This page is the story of why it endures.

It began with the Gion Goryo-e of 869

The origin dates to the Heian period, the year 869. When a plague swept the country, 66 halberds - one for each province of the time - were raised at Shinsen-en, the imperial garden in Kyoto, and portable shrines were sent from the Gion shrine, which enshrined Gozu Tenno, to pray for an end to the disease. This rite, the Gion Goryo-e, is the starting point of the festival. Its 1,150th anniversary was celebrated in 2019.

Gozu Tenno and 'goryo' belief

People of the age believed that epidemics and disasters were caused by the vengeful spirits (goryo) of those who had died unjustly. Within this belief in placating angry spirits, Gozu Tenno was revered as especially powerful against plague. The Gion shrine (today's Yasaka Shrine) enshrined him; in the Meiji-era separation of Shinto and Buddhism the deity was recast as Susanoo-no-Mikoto and the shrine renamed Yasaka.

How the floats became a 'moving museum'

From medieval times, the town merchants (machishu) used their growing wealth to compete in decorating the floats, draping them in imported tapestries until the procession became a 'moving museum'. Ownership of the festival shifted from the court to the townspeople - which is exactly why, though it was halted again and again by the Onin War and later destruction, the townspeople rebuilt it every time. That sense of 'our festival' is the engine behind 1,150 years of continuity.

Why it still continues (in short)

• A universal prayer: the wish for protection from disease and disaster transcends every era.
• Owned by the town: each float neighbourhood, not the government, sustains it - so the line of succession is clear.
• Heritage value: the Yamahoko float event is on UNESCO's Intangible Cultural Heritage list, with structures in place to preserve it.
