The castle is well known for being mainly built from large earthen embankments. There is very little stonework and that os mainly to fortify some foundations. The large main keep looking building is a museum and is not an accurate representation of an Edo Period yagura. The Omotemon Gate however was faithfully reconstructed in 2001. The Omonogashira Gobansho (guard house) is the only remaining original structure on the site. The castle was much bigger and more interesting that I expected. The earthen embankments around each Bailey are in interesting feature and I tried to highlight them in some of the photos here.
Osumiyagura Museum is open 9-4:30, closed Dec 1 to March 31; 100 yen
