Momijigari

Momijigari (紅葉狩り) is the Japanese tradition of visiting areas where leaves have turned red in the autumn. The word comes from the two Japanese words momiji (紅葉) meaning "red leaves" or "maple tree" and kari (狩り), "hunting". It is also called kōyō (紅葉).[1] "Kōyō" is another pronunciation of the characters for "momiji". In Hokkaidō another word for it is kanpūkai (観楓会).
