Two three-story turrets stand side by side — a Harima castle five minutes from the station
Built in 1619 on Hitomaru Hill in Akashi, Hyogo Prefecture, Akashi Castle was Ogasawara Tadazane's Tokugawa stronghold watching the western daimyo. No keep was ever raised, but the Tatsumi and Hitsujisaru three-story turrets still stand together — both Important Cultural Properties.

Top 3 Highlights
1.The Twin Three-Story Turrets Standing Side by Side
Two three-story yagura standing together on the southern stone walls of the inner bailey is a sight found in very few castles. The Hitsujisaru came from the Fushimi Castle keep and the Tatsumi from the Funage Castle keep — both are now Important Cultural Properties.

2.Tatsumi Yagura — National Important Cultural Property
A three-story layered tower five ken wide and four ken deep, the Tatsumi Yagura was identified in 1982 as a relocated Funage Castle keep. Its first floor opens free of charge on weekends and holidays in spring (March-May) — a rare chance to inspect the timber framework up close.

3.Cherry Blossoms with Stone Walls in Spring
Inside the inner moat lies Hyogo Prefectural Akashi Park, on Japan's Top 100 Cherry Blossom Sites list. The contrast of stone walls and pink petals along the moat-side promenade makes it one of Kansai's premier hanami spots, drawing crowds every spring.

Insider Tips
- 1.The Tatsumi Yagura opens its first floor free of charge only on spring weekends and holidays (March-May), and the Hitsujisaru only on autumn weekends (September-November). Plan around the season, or check the official site for the current opening calendar.
- 2.From the north exit of JR Akashi Station you can already see the turrets and stone walls from the platform itself. Take a shot from the north end of the platform before going through the gate to capture station and castle in a single rare frame.
- 3.The Musashi Garden in the third bailey was laid out in 2003 to honor the swordsman's role in planning the castle town. The small gravel-and-stone garden is free to enter and pairs naturally with the keep ruins for travelers tracing Musashi's trail.

Detailed History
Akashi Castle's history begins in 1617 (Genna 3), when Ogasawara Tadazane, newly transferred from Matsumoto as daimyo of the 100,000-koku Akashi Domain, was ordered by Shogun Tokugawa Hidetada to build a castle. The Tokugawa chose this site as their second western stronghold after Himeji to watch the tozama daimyo. Akashi sat on the San'yo highway where roads to Tanba split north and ferries ran south. Hitomaru Hill on Mount Akamatsu was chosen for its natural defensive pond. Hatamoto officers were dispatched as commissioners with one thousand kan of silver. Timber was salvaged from the dismantled Miki, Takasago, Edayoshi, and Funage castles. Tradition holds the Hitsujisaru used materials from Fushimi Castle and the Tatsumi from Funage Castle, and Hosokawa Tadaoki sent parts of the Nakatsu Castle keep. Construction began in early 1619, and by 1620 Tadazane had moved in from Funage. A stone tenshu platform was raised but no main keep was ever built; four three-story yagura (Tatsumi, Hitsujisaru, Inui, Ushitora) were placed at the corners instead. Chronicles including the Sekishi-shichu-ki and Harima-kagami record that Miyamoto Musashi, then a guest of Tadazane, directed the town layout. In 1632 (Kan'ei 9) Tadazane was transferred to Kokura. A rapid succession of lords followed — the Toda-Matsudaira, Okubo, Matsudaira (Fujii), and Honda — until 1682 (Tenna 2), when Matsudaira Naoaki of the Echizen branch took possession with 60,000 koku. The shinpan Matsudaira held the castle for ten generations and 189 years. Because the buildings were salvaged timber, they aged quickly, and the second lord Naotsune carried out major repairs in 1739 (Genbun 4). The 1874 Abolition of Castles ended its role under the last lord Matsudaira Naomune. The Ushitora Yagura was dismantled in 1881 for school construction, the Inui in 1901 to repair the Hitsujisaru. Citizens opened Akashi Park in 1883; the prefecture took over the park on April 15, 1918. The Tatsumi and Hitsujisaru became Important Cultural Properties on June 18, 1957, and the site a National Historic Site on September 30, 2004. The Great Hanshin Earthquake of January 17, 1995 caused major damage; a five-year restoration completed in 1999 lifted the turrets, repaired foundations, and replaced the wooden wall. On April 6, 2006 it was selected as Japan's Top 100 Castles, number 58.
Cultural Significance
Akashi Castle's greatest cultural value lies in two three-story yagura from the early Edo period that still stand side by side. The Tatsumi and Hitsujisaru Yagura became Important Cultural Properties on June 18, 1957, and the site became a National Historic Site on September 30, 2004. During 1982 (Showa 57) renovation work, both turrets were confirmed as relocated keeps — the Hitsujisaru from Fushimi Castle and the Tatsumi from Funage Castle — re-establishing them as key examples of late Sengoku and early Edo architecture. Miyamoto Musashi's role in the town layout is recorded in the Sekishi-shichu-ki, Harima-kagami, Bansyu-akashi-kiroku, and the Memoirs of Ogasawara Tadazane, and the castle is now a pilgrimage site for kendo and budo enthusiasts. The fifth daimyo Matsudaira Nobuyuki chose ten scenic spots within and named it Kiharu-jo, the Castle of Joyful Spring. After the 1898 Imperial designation and 1918 park opening, the inner moat grounds joined Japan's Top 100 Cherry Blossom Sites. In 2018 NHK's Rekishi Hiwa Historia featured the castle as a definitive example of standardized turret architecture by master builder Nakai Masakiyo. For the 400th anniversary, large-scale re-plastering was carried out in 2019, and Akashi City now plans to reconstruct the Taiko-mon gate, more turrets, the chief retainer's residence, and earthen walls.
Architectural Details
Akashi Castle is a hybrid layered-bailey hilltop castle on Hitomaru Hill (Mount Akamatsu): the inner bailey at center, second and east baileys east, third bailey south, Inari bailey west. The Akashi River formed a natural outer moat west, a canal-harbor (today's Port of Akashi) ran south, and the Kounoike pond protected the north. Main bailey stone walls were built by the Tokugawa directly; the third bailey was a joint project. The southwestern tenshu platform measures roughly 25m east-west and 20m north-south — about 152 tsubo, large enough for a five-story keep — but no tower was ever built. Three-story yagura took the corners instead. The Tatsumi measures five ken wide, four ken deep, and seven ken one sun tall, with an irimoya roof whose gables face east-west, and incorporates the Funage Castle keep. The Hitsujisaru measures six ken wide, five ken deep, and seven ken two shaku nine sun tall, with gables facing north-south, and incorporates the Fushimi Castle keep — the Compendium of Japanese Castles calls it a substitute keep. The differing gable orientations are unusual, and the towers are cited as a definitive Edo example of the standardized system by master builder Nakai Masakiyo. Stone walls damaged in 1995 were restored over five years using a hikiya building-move to lift the turrets, repair foundations, and return them to position, completing in 1999.
