Completed in 1622, this diminutive castle of the Ii family of daimyō (domain lords) is rightly considered a national treasure; much of it remains in its original state. One unusual feature: teppōzama and yazama , outlets for shooting guns and arrows, designed to be invisible from the outside until being popped out for use. Upper storeys have great views across Biwa-ko. Surrounded by more than 1200 cherry trees, the castle's also very popular for springtime hanami (blossom viewing).
The castle is a 10-minute walk up the street from the station (take a left before the shrine, then a quick right, or walk through the shrine grounds).
