Didn't you learn anything, Kal?
It is very difficult for also Japanese to answer Sagamibara.
Sagamibara is located Kanagawa prefecture, but Kanagawa has 2 big cities, Yokohama and Kawasaki...so we are always blocking the name of this third biggest city!
I knew Tokyo as usual, Osaka I remembered my geography teacher taught us that it was once called manchester of Japan. Hiroshima - nuclear bombs, Yokohama - shipping hub, Kobe - longest suspension bridge, and other cities I guessed though !
