Gangara Fire Festival

Ready to feel the heat? Step into the flames of tradition at this blazing festival! Held annually in August in the town of Ikeda, just north of Osaka, the Gangara Fire Festival lights up the night with a stunning display of flames. The event starts with the dramatic lighting of the characters 大 (Dai) and 大一 (Daiichi) on the side of Satsuki Mountain. This is followed by a procession of massive 4-meter torches, weighing 100 kilograms each, carried 3 kilometers through the city streets. The festival is rooted in the worship of Atago, the deity believed to protect against fire, a tradition that dates back to the Edo period. With its giant torches, mountain fire symbols, and dramatic procession, the Gangara Fire Festival is a powerful and must-see celebration of Ikeda’s history.

Immersive Museum OSAKA 2025

What do Van Gogh and Hokusai have in common? Learn more about how Japanese ukiyo-e prints helped ignite Impressionism in Europe at Immersive Museum Osaka. Artists like Hokusai, Hiroshige, and Kuniyoshi depicted everyday life and nature through bold compositions, dynamic perspectives, and in vivid color that struck a chord among artists in 19th-century Parisians, sparking Japonisme in France. Western painters like Monet, Degas, and Van Gogh absorbed Japanese aesthetics found in ukiyo-e, transforming their own styles and reshaping modern art.

In a time before quick global connectivity, these two artistic traditions connected and influenced each other across vast distances. Now, you can step into that shared story, one that transcends continents and centuries, at Immersive Museum Osaka.
