Sakaiminato Japan. Wedged between sea, sky, and mountains, this small fishing port has been known for centuries for its superb seafood. Here, the Sea of Japan yields up both crab and hon-maguro. The prized Blue-fin tuna is esteemed by gourmets around the world. Sakaiminato is also your gateway to a very ancient region of Honshu. West of the city lies Izumo-Taisha, one of the oldest and holiest shrines in Shinto.
