Sumoto Castle on Awaji Island is a reconstructed castle but still has many of its original stone walls. There are superb views from the top of the hill where it is located.

Sumoto Castle, now only ruins, is not a well known castle, nor is it very easy to get to. It only operated as a castle for a relatively short period. However, it was an impressive mountaintop castle, and most of the stonework still remains today.
It is located on top of Mount Mikuma, 133 meters above sea level. It looks down on the town of Sumoto, the biggest town on the island of Awajishima. In its day, the castle was a key part of Toyotomi Hideyoshi's defense of his headquarters in Osaka.

History
The first castle constructed was in 1526. Although the English word "castle" is not really appropriate as the fortifications were built of earth and wood and would probably best be described as a fort. Many of the earliest Japanese castles would have been constructed this way.
This initial construction was undertaken by Atagi Haruoki, a retainer of the Miyoshi clan who ruled a part of Shikoku as well as part of what is now Osaka Prefecture.
In 1581 Toyotomi Hideyoshi took control of Awaji Island and put Hidehisa Sengoku in charge of the island and the castle. It is believed it was Hidehisa who began the expansion and rebuilding of Sumoto Castle and the oldest stonework was done under his bidding.
Hideyoshi removed Hidehisa in 1585 and replaced him with Hachisuka Yoshihide. It was he who greatly expanded and reinforced the castle to protect Hideyoshi's main base in Osaka. Sumoto was one of four castles that fulfilled this role, one for each of four directions surrounding Osaka.
After the defeat of Hideyoshi's clan at the Battle of Sekigahara in 1600, the Tokugawa gave Awaji Island to the Ikeda Clan who ruled Himeji Castle. So they abandoned Sumoto Castle and moved to Yura Castle closer to Himeji in the north of the island.
In 1616 after the fall of Osaka Castle the Tokugawa gave Awaji Island to the Hachisuka clan based in Tokushima on Shikoku.
They in turn appointed the Inada clan to govern the island and moved back to Sumoto but rather than occupy the mountaintop castle they reinforced the base of the mountain and governed from there.
Some impressive stone walls and part of the moat still exist today and it is where the Awajishima Museum is now located. The museum has a lot of displays and artifacts from the castle's history.
All the castle buildings on the mountain were dismantled in 1642 under the Edo Period edict that limited each domain to just one castle.
In 1928, the curious concrete keep was built, making it the oldest reconstructed keep in Japan. In scale or design it is not an accurate rendition of what stood there before.
Special emphasis is given to the rulers of Awaji, which was in ancient times a separate province but since the Edo Period was ruled from what is now Tokushima on Shikoku. There's plenty on Sumoto Castle, on the hill above the museum, which was the main castle on Awaji during the Edo Period.

Panorama
A visit to the castle ruins can be enjoyed by those with an interest in Japanese castles, or those who seek out panoramas.
The stone fortifications extend for almost 300 meters along the ridge and give a good idea how impressive the castle must have been in its heyday.
The walking paths around the mountaintop are great for nature strolls and offer some expansive views down to town below. The view extends across Osaka Bay to Wakayama and Kansai International Airport. About 20 kilometers up the coast of Awaji you will see the gleaming, white, 100 meter tall Giant Kannon Statue.
