Sometimes life just doesn't work out the way you had planned it.
In 1846 a young samurai teacher from Kyoto was residing in Tokyo, when he was assassinated. To avenge his death, his older brother, Amano Shinsuke, traveled incognito to Tokyo, and developed a plan to hang out next to the highway, thinking that he would surely be able to catch the killer there: everyone who traveled to or from Tokyo was bound to pass at that point. In order to observe the travelers he started a small shop making and selling sweet sake (amazake).
He never ever found the man who killed his kid brother, but the shop is still there, now run by the 7th generation of incognito samurai.
