Azuchi Castle Castle

Azuchi Castle was a late 16th century Japanese castle built by the warlord Oda Nobunaga on the shores of Lake Biwa in what is now Shiga Prefecture. Constructed as both a military fortress and a stately residence, it was known for its tall central keep and ornate design.

The castle was destroyed in 1582 following political turmoil in the region, and only stone bases and archaeological remains survive on the original hilltop site. Excavations and on-site displays, plus a nearby museum, present artifacts and reconstructions that interpret the castle’s original layout and appearance.

The ruins lie near the modern town of Azuchi on the southern shore of Lake Biwa, and the location is accessible from regional transport links; the site is valued for its historical importance in Japan’s Sengoku period.

• Founder and style: Originally built as the fortress and lavish residence of the warlord Oda Nobunaga in the late 16th century and noted for its tall central donjon and innovative architecture for the period.
• Current remains: Destroyed shortly after 1582 and today the site is largely archaeological with foundations and exposed stonework; a museum nearby displays finds and interpretive material.

Azuchi is in Ōmihachiman area of Shiga Prefecture near Lake Biwa. From JR Omi-Hachiman Station (on the JR Biwako Line) take a local bus or taxi to the Azuchi castle site; it’s a roughly 15-20 minute drive. Regional trains from Kyoto and Osaka connect to the Biwako Line.
