Thanks to Tokugawa's destruction of the castle after the Battle of Sekigahara, there is not much left to see. There are a couple trenches and if you follow the trail down into the Taiko Kuruwa, you can see some nice remaining earthen embankments around the bailey. Around the Honmaru, there are 2 places where there should be a few stones from the original stone walls, but I could only find one. The second was recently uncovered and may have been weeded over again when I visited. The best reason to visit Sawayama Castle is for the great views of Hikone Castle.
