Yoshinori Yanagisawa is a Professor of Economics at Y University. He always walks on the right side of the road and only crosses the street at designated pedestrian crossings. He will walk the extra mile in search of cheap and tasty "saba" (mackerel). This story is an entertaining record of the life of a civilized scholar who abides by the the laws of the road and by the laws of the free market.
