This is a small settlement in the Mantis Islands which is technically ruled by the Tortoise, occupied by a dozen Kasuga and hundreds upon hundreds of Yoritomo. While it is often stated the Mantis gifted the city to the Tortoise to demonstrate brotherhood, more likely it was little more than a bribe. Regardless of the truth, the Tortoise have been able rulers, amiable to Mantis desires and happy to be able to keep a closer watch over their trade with the gaijin.
