A partially preserved Edo-period stroll garden on the shore of Lake Biwa, a short walk north of Hikone Castle. Also known as the Ohama Goten Gardens, this was the lakeside villa of the Ii clan, built to take advantage of views across Japan's largest lake. Stone lanterns and pine trees frame the water on three sides; the garden has a quieter, less manicured feel than Genkyu-en.
The garden is undervisited compared to the castle grounds, which makes it a good place to escape the tour groups. The lakeside position means cool breezes in summer. Free entry, open during daylight hours.
