As I reach the bottom of Japan, before starting my return to Tokyo, lies the most important stop. Just between Fukuoka and Shimonoseki lies a shitty little island called Ganryu-ijima. Covered in sea roaches, hornets, sand fleas, crabs, clams, and other creepy crawlies that tried to eat me. No electricity and just a handful of ferries a day, but on the little island, over 400 years ago the most famous samurai duel in history took place between Miyamoto Musashi and Kojiro Sasaki. Musashi's boat had capsized on the way to the island and he lost his sword in the water, only a single boat oar remaining he carved it into the shape of a bokuto(now referred to as a Suburrito) since he was extremely late, Sasaki in his rage met Musashi in the water and lunged at him, with the sun behind his back hiding his creation, he crushed Sasaki's skull with a single downward stroke. This was his last battle and afterwards retired to write The Book of Five rings. A strategy book still used to this day by generals all over the world and the inspiration to Tsun Zu's Art of War.
