Overview
What is a Japanese castle?
Japanese castles were built mainly from the 16th century as lords' residences and military strongholds, usually with a keep (tenshu), moats and stone walls. Many were dismantled or destroyed over time, and a number of keeps you see today are reconstructions. A small group of original keeps survives and is highly prized.
Original keeps and national treasures
Only about a dozen castles still have their original keep, and five of them are designated National Treasures: Himeji, Matsumoto, Inuyama, Hikone and Matsue. Posts about these castles are popular on the map, especially Matsumoto Castle with its black walls and autumn leaves in the frame.
Stone walls and mountain castles
Not every castle has a keep. Marugame Castle is known for its tall curved stone walls, and posts about mountain castles such as Takatori and Bitchu Matsuyama show stone walls rising out of the forest. Expect a real climb at mountain sites.
Best seasons and times of day
Spring brings cherry blossoms around the moats, and autumn brings red leaves. Early morning light and illuminations after dark offer a different mood, and some mountaintop castles are photographed above a sea of clouds. Opening hours and illumination dates vary, so check official information.
Etiquette and photo tips
Do not climb on stone walls or step off marked paths, and follow the rules inside the keep, where shoes are often removed and stairs can be very steep. Tripods may be restricted in busy areas. Include moats, bridges or surrounding trees in your frame to show the scale of the castle.
Know Before You Go
Check opening days
Keeps often close on certain days or during maintenance, and some are open only on limited dates. Check the official website before you go.
Stairs inside keeps
Original keeps have steep, narrow stairs, and shoes are usually taken off or carried in a bag. Wear socks and comfortable clothes.
Mountain castles
Castles such as Takatori involve a long uphill walk on uneven ground. Wear walking shoes, bring water and check the weather beforehand.
Respect the stonework
Do not climb or sit on stone walls and do not leave the marked paths. Many sites are protected cultural properties.
Crowds
Famous castles such as Himeji and Matsumoto can be busy on weekends, holidays and in the cherry blossom and autumn leaf seasons. Arriving early is recommended.
