Today is World Instant Noodle Day. Instant noodles were invented in the city we're looking for in today's Geo Quiz. The man who came up with instant noodles was named Momofuku Ando.

World Instant Noodles Association executive Norio Sakurai says Ando started working on the idea after Japan's defeat in World War Two.

"He saw the devastation of the war, and he wanted to create something which is nutritious, tasty, and stirrable, and easy to prepare at a reasonable price."

He did. The world's first pre-cooked instant noodle -- Chicken Ramen -- was born 50 years ago today. It made its debut in a city in Japan's Osaka Prefecture.

That's the city we're looking for today. About 100,000 people live there. Some of them participated in the city's annual Gangara Fire Festival yesterday. It concluded with a torchlight procession up Mount Satsuki.

Others paid a visit to one of the city's tourist attractions. It's the Momofuku Ando Instant Ramen Museum. Heat up the answer to today's Geo Quiz here ...
