Former Yokohama Specie Bank Head Office: A Stone Sentinel of Meiji-Era Finance
Step out of Bashamichi Station in central Yokohama and you will find yourself face to face with one of the most commanding pieces of architecture in modern Japan. The Former Yokohama Specie Bank Head Office (旧横浜正金銀行本店, Kyū Yokohama Shōkin Ginkō Honten) rises from the corner of Minami-naka-dōri with the gravitas of a European capital. Its massive stone façade, banded with Corinthian columns and crowned by a great octagonal dome, tells a story far larger than that of a single building. It is a monument to the moment Japan emerged onto the world's financial stage, designed by one of the three giants of Meiji architecture and saved across a century of earthquakes, war, and reinvention. Today it serves as the Kanagawa Prefectural Museum of Cultural History, where the architecture is itself the most prized exhibit.
Historical Background: The Bank that Financed an Empire's Trade
To understand the building, one must first understand the bank that built it. The Yokohama Specie Bank (横浜正金銀行) was founded in 1880 (Meiji 13), just two decades after the port of Yokohama opened to foreign commerce. The word shōkin literally means "specie" — that is, gold and silver coin rather than paper notes. The young Meiji government, alarmed that foreign merchants and foreign banks controlled almost all of Japan's international trade settlements, established the bank as a national instrument to recapture that business and to handle foreign exchange in hard currency.
What began as a defensive measure soon became a powerhouse. By 1900 the Yokohama Specie Bank was lending some forty-five million yen a year — four times the combined lending of all the zaibatsu banks. Branches were opened in London, New York, Lyons, Bombay, Shanghai, and Beijing, and the institution eventually grew into one of the three great exchange banks of the world. Its presidents included men who would later serve as Minister of Finance, among them Takahashi Korekiyo and Inoue Junnosuke, and the novelist Nagai Kafū once worked as a clerk at one of its overseas branches.
By the turn of the twentieth century the bank had outgrown its original premises and commissioned a new head office worthy of its global stature. Ground was broken in March 1899 and the new building was completed in July 1904 at a reported cost of 1.1 million yen — an astronomical sum at the time.
The Architect: Tsumaki Yorinaka, Master of Meiji Modernity
The man entrusted with the design was Tsumaki Yorinaka (妻木頼黄, 1859–1916), today regarded alongside Tatsuno Kingo (designer of Tokyo Station and the Bank of Japan) and Katayama Tōkuma (designer of the Akasaka Detached Palace) as one of the three towering architects of the Meiji era. Tsumaki was unusually cosmopolitan even by the standards of that ambitious generation. Orphaned in childhood, he studied at Keio University, then crossed the Pacific to New York as a teenager, eventually graduating in architecture from Cornell University in 1894. He also spent time in Berlin, working in the offices of Wilhelm Böckmann and Hermann Ende, two of the German architects then advising the Japanese government on its new capital.
This triple grounding — British-influenced training in Tokyo, American university education, and direct German experience — gave Tsumaki an unusually broad palette. He went on to design the Nihonbashi Bridge in Tokyo, the Yokohama Red Brick Warehouses, and numerous Ministry of Finance buildings across the country. The Yokohama Specie Bank head office is widely considered his masterpiece.
Why It Was Designated: A Building Recognised Twice Over
The Former Yokohama Specie Bank Head Office is one of only a handful of properties in Japan to hold two separate national designations. It was registered as an Important Cultural Property (Jūyō Bunkazai) on March 12, 1969, primarily for its architectural value as a representative work of early-twentieth-century Western-style construction in Japan. The citation by the Agency for Cultural Affairs notes that the exterior is exceptionally well preserved and that the design is of outstanding quality among Meiji-period Western buildings.
Then, on June 27, 1995, the surrounding grounds were designated a National Historic Site (Shiseki) — a particularly remarkable honour because it was awarded simultaneously with the Hiroshima Atomic Bomb Dome, making this pair the first modern (rather than ancient or medieval) properties to receive that status. The historic-site designation recognises the building's central role in the development of Japan's modern international trade and finance. In 2007 the Ministry of Economy, Trade and Industry further added it to the list of Modernization Industrial Heritage Sites of the Yokohama port area.
Architectural Highlights: A Lesson in Neo-Baroque on Japanese Soil
The style is generally described as Neo-Baroque with strong German Renaissance influences. The building is three stories tall with a single basement, constructed in reinforced brick faced with stone — a hybrid technique that proved decisive in its survival of the 1923 Great Kanto Earthquake.
The Grand Corinthian Order
What strikes the visitor first is the magnificent giant order of Corinthian columns and pilasters that wraps three faces of the building, those facing Bashamichi, Minami-naka-dōri, and Benten-dōri. The capitals were carved in deep, finely worked stone, executed by master stonemasons under the direction of the Ibaraki-based stone contractor Nakano Kisaburō. Three different stones were used in carefully chosen positions: Makabe-ishi for the columns and main entrance details, Shirochōba-ishi for the plain walls of the second and third storeys, and Kitagi-ishi for the cornice mouldings and stairs.
"The Ace Dome"
Crowning the central façade is the great octagonal copper-clad dome that has become the building's emblem. It is affectionately nicknamed "the Ace Dome" (エースのドーム). In Yokohama, three nearby towers are traditionally called the King (the prefectural government headquarters), the Queen (the customs house), and the Jack (the Port Memorial Hall) — playing-card names said to have been coined by foreign sailors. The museum staff later gave the bank's dome the matching name of "Ace," completing the set and inviting visitors to feel a deeper affection for the building.
It is worth noting that the original dome did not in fact survive the twentieth century intact. The 1923 Great Kanto Earthquake itself did not topple the structure, but the firestorm that followed gutted the interior and destroyed the dome. The bank was rebuilt without it. The current dome is a reconstruction completed in 1967, when the building was converted into the prefectural museum, restoring Tsumaki's original silhouette to the Yokohama skyline.
The Former Entrance Hall
Of the interior spaces, only the former entrance hall on the first floor retains its Important-Cultural-Property designation, the rest of the interior having been remodelled across successive renovations. The hall preserves the dignified marble, plaster, and ironwork of an Edwardian-era banking palace and is open to public viewing and photography.
Surviving the Twentieth Century
The building's biography reads like a chronicle of modern Japan itself. It opened in 1904 to handle the foreign-exchange business that financed the country's rapid industrialisation. It was scorched by the firestorm of the 1923 earthquake and rebuilt the following year. It continued as the Specie Bank's head office through the 1930s, when the institution had branches across Asia, Europe, and the Americas. In 1946, with Japan's defeat in the Second World War, the bank was dissolved by order of the Occupation authorities; its foreign-exchange business was inherited by the Bank of Tokyo, which through later mergers became today's MUFG Bank.
In 1964 Kanagawa Prefecture purchased the building, and after careful restoration — including the reconstruction of the dome and the addition of a new wing — it opened as the Kanagawa Prefectural Museum in March 1967. A further round of renovation in 1995 transformed it into the present Kanagawa Prefectural Museum of Cultural History.
Visitor Information
Today the building is operated as the Kanagawa Prefectural Museum of Cultural History (神奈川県立歴史博物館). Its permanent exhibition presents the history of Kanagawa across five thematic sections, from the ancient peoples of Sagami through the medieval samurai capital of Kamakura, the highways of the Edo period, the opening of the port of Yokohama, and modern Kanagawa.
Please note: The museum is currently closed for major structural-renovation works and is scheduled to reopen on October 16, 2026. Visitors are strongly advised to confirm the latest status on the museum's official website before planning a visit. Even during the closure, the magnificent exterior of the building can still be admired freely from the surrounding streets — and arguably this is when its sheer architectural presence is appreciated most directly, without the distraction of the modern entrance flow.
When the museum is open, standard hours are 9:30 a.m. to 5:00 p.m. (last entry 4:30 p.m.), closed on Mondays (or the following day if Monday is a public holiday), during the New Year period, and on designated collection-maintenance days. Admission to the permanent exhibition is typically 300 yen for adults, with discounts for students and seniors. Photography is permitted in the historic former entrance hall.
Getting There and Surrounding Attractions
The building stands at one of the most accessible cultural-history clusters in all of Japan. Bashamichi Station on the Minatomirai Line is roughly one minute on foot from the entrance, via Exit 5. From the JR lines, both Kannai and Sakuragicho stations are within a comfortable five-to-eight-minute walk.
Once on foot, a remarkable concentration of heritage architecture is within easy reach:
- The Yokohama Red Brick Warehouses (Akarenga Sōko), also designed by Tsumaki Yorinaka, now reimagined as a popular shopping and event complex.
- The Yokohama Three Towers — the King (Kanagawa Prefectural Government Office), the Queen (Yokohama Customs), and the Jack (Yokohama Port Opening Memorial Hall). The latter two are themselves Important Cultural Properties.
- The historic Bashamichi shopping street, named for the horse-drawn carriages that once carried foreign residents through what was Japan's first cosmopolitan district.
- The Yamashita Park waterfront and the moored ocean liner Hikawa Maru.
- The vibrant streets of Yokohama Chinatown, the largest in Japan.
- The futuristic Minato Mirai 21 district, where the historic core meets contemporary high-rise Yokohama.
A leisurely half-day itinerary can easily combine the exterior viewing of the Specie Bank with the Three Towers, the Red Brick Warehouses, and a lunch break in Chinatown — a walk through the layers of modern Japanese history.

Q&A
- Can I go inside the building?
- When the Kanagawa Prefectural Museum of Cultural History is open, visitors may enter through the modern museum entrance and view the permanent exhibitions, as well as the historic former entrance hall (the only interior space that retains its Important Cultural Property designation). Please be aware that the museum is currently closed for renovation works until October 16, 2026; the exterior, however, remains visible from the street at any time.
- What is the "Ace Dome" and why is it called that?
- The great octagonal dome that crowns the building has been affectionately nicknamed the "Ace Dome." Three other nearby towers — the prefectural government office, the customs house, and the port memorial hall — are traditionally called the King, Queen, and Jack of Yokohama, said to have been named by foreign sailors. The bank's dome was later christened the Ace to complete this playing-card-themed quartet of Yokohama landmarks.
- Is the dome the original Meiji-era one?
- The current dome is a faithful reconstruction. The original dome was destroyed in the fires that followed the 1923 Great Kanto Earthquake, and the building was repaired without it for several decades. When the structure was converted into the prefectural museum in 1967, the dome was rebuilt to restore the silhouette designed by Tsumaki Yorinaka.
- How does it relate to today's banks?
- The Yokohama Specie Bank was dissolved in 1946 by order of the Allied Occupation authorities. Its foreign-exchange business was inherited by the Bank of Tokyo, which through subsequent mergers became today's MUFG Bank. The Specie Bank can therefore be considered one of the institutional ancestors of one of Japan's largest contemporary financial groups.
- Is there an admission fee just to see the building from outside?
- No. The exterior stands on a public corner in central Yokohama and can be admired freely from the surrounding sidewalks at any time of day. Many visitors choose to circle the building, since each of its three principal façades — facing Bashamichi, Minami-naka-dōri, and Benten-dōri — offers a different view of the great Corinthian columns and dome.
