Einstein visited Japan in November 1922, and it was during this trip that he heard he had won the Nobel Prize. Throngs of people showed up to see him deliver lectures, and one lucky bellhop walked away with a once-in-a-lifetime souvenir. The always curious Einstein remained baffled by the country's music, calling it "entirely incomprehensible” in his diary. “Yesterday I heard another one singing away again to the point of making me dizzy.” Tourists looking to trace the physicist's steps should visit Kyoto and Tokyo, as well as other Asian stops Einstein and his wife Elsa made to Singapore, Hong Kong and China.
