Awaji

Awaji lies between the shores of Honshu and Shikoku, guarding the eastern entrance to the Inland Sea. At Sumoto, a mountain castle overlooked the island's eastern shore. Wakisaka Yasuharu took possession in 1585 and rebuilt it with stone walls. After the fall of Osaka in 1615, the Hachisuka lords of Awa received Awaji; their retainers later made Sumoto the centre of their administration of the island.
