Nobunaga's Ambition (信長の野望) series
Koei's long-running grand strategy series in which players command warlords during Japan's Sengoku period. Capturing and developing castles is the central gameplay loop — virtually every castle in this database appears as a location. The series spans over 15 mainline entries from 1983 to the present.
Castles Featured
Himeji Castle
姫路城 · Himeji-jo
📍 Hyogo — Kansai
The undisputed king of Japanese castles — the only one that has never been captured, never burned, and never rebuilt.
Osaka Castle
大阪城 · Osaka-jo
📍 Osaka — Kansai
Japan's most famous castle story wrapped in a 1931 concrete tower — the history is spectacular, even if the building isn't original.
Kumamoto Castle
熊本城 · Kumamoto-jo
📍 Kumamoto — Kyushu
Japan's mightiest castle complex — proven in battle, broken by earthquake, and rising again through one of history's most ambitious restoration projects.
Nagoya Castle
名古屋城 · Nagoya-jo
📍 Aichi — Chubu
Nagoya Castle is mid-renovation — visit now for the stunning reconstructed palace, return in a few years for the completed wooden tower.
Inuyama Castle
犬山城 · Inuyama-jo
📍 Aichi — Chubu
The oldest surviving castle tower in Japan — compact, dramatic, and perched above a river just as it was when Oda Nobunaga's family built it in 1537.
Nijo Castle
二条城 · Nijo-jo
📍 Kyoto — Kansai
The castle where the shogunate both began and ended — Nijo is a palace of power politics, famous for floors that sing and paintings that dazzle, not for towers or battles.
Aizu-Wakamatsu Castle
会津若松城 · Aizu-Wakamatsu-jo
📍 Fukushima — Tohoku
The castle where samurai Japan ended — Aizu-Wakamatsu carries the weight of the Byakkotai tragedy and the Boshin War's last stand, making it Japan's most emotionally resonant castle site.
Hiroshima Castle
広島城 · Hiroshima-jo
📍 Hiroshima — Chugoku
The castle that atomic fire erased and Hiroshima's spirit rebuilt — visiting here is inseparable from the city's most profound history.
Edo Castle
江戸城 · Edo-jo
📍 Tokyo — Kanto
The largest castle ever built in Japan — now the Emperor's residence — where you can walk the foundations of the tower that ruled a nation for 265 years.
Kanazawa Castle
金沢城 · Kanazawa-jo
📍 Ishikawa — Chubu
The silver-roofed castle of Japan's wealthiest samurai clan — best experienced alongside Kenrokuen, the garden that its lords spent 300 years perfecting next door.
Sendai Castle
仙台城 · Sendai-jo
📍 Miyagi — Tohoku
The mountain stronghold of the One-Eyed Dragon — where Date Masamune's equestrian statue surveys the city he founded, from ruins that speak of a castle that never needed a main tower.
Odawara Castle
小田原城 · Odawara-jo
📍 Kanagawa — Kanto
The castle that Hideyoshi could not storm — famous less for its tower than for the legendary city-swallowing earthworks and the indecisive council that became a Japanese proverb.
Ueda Castle
上田城 · Ueda-jo
📍 Nagano — Chubu
The castle that humiliated Tokugawa twice — Ueda's surviving turrets are modest, but the history of Sanada Masayuki's impossible victories makes it one of Japan's most compelling castle sites.
Gifu Castle
岐阜城 · Gifu-jo
📍 Gifu — Chubu
This is the mountain where Nobunaga declared he would rule Japan — and the view from 329 meters makes it easy to believe him.
Fukuoka Castle
福岡城 · Fukuoka-jo
📍 Fukuoka — Kyushu
One of Kyushu's largest castle complexes, now a cherry blossom park overlooking the bay where the Mongol armadas once appeared on the horizon.
Odani Castle
小谷城 · Odani-jo
📍 Shiga — Kansai
Where Nobunaga's sister lived, loved, and lost — the mountain castle of the doomed Azai clan, with one of the great tragic stories of the Sengoku era.
Azuchi Castle
安土城 · Azuchi-jo
📍 Shiga — Kansai
The most historically important castle in Japan — Nobunaga's revolutionary 1579 masterpiece that invented the Japanese castle as we know it, gone after three years, its foundations still visible under the trees.
Kiyosu Castle
清洲城 · Kiyosu-jo
📍 Aichi — Chubu
Where Nobunaga launched his conquest of Japan and where Hideyoshi's genius at the 1582 conference made him the successor — Japan's most consequential castle for two of its greatest leaders.
