Meiji 44 Hall (Former Karuizawa Post Office): A Mint-Green Western-Style Treasure in the Highlands
Tucked into the wooded grounds of Karuizawa Taliesin, beside the gentle waters of Lake Shiozawa, stands a charming two-story Western-style building painted in soft mint green. This is the Meiji 44 Hall, originally built in 1911 (Meiji 44) as the Karuizawa Post Office and now registered as a National Tangible Cultural Property of Japan. For over a century, this elegant little building has witnessed the transformation of Karuizawa from a quiet post town along the Nakasendo road into one of Japan's most beloved highland resorts, beloved by foreign missionaries, diplomats, and Japan's most celebrated literary figures.
Historical Background: From Post Town to International Resort
Karuizawa's modern history began in earnest in the late nineteenth century, when the Canadian missionary Alexander Croft Shaw and his friends rediscovered the town as a cool summer retreat in 1886. As foreigners and influential Japanese figures began building summer villas in the highlands, the demand for reliable communication services grew rapidly. The original Karuizawa Post Office had been established in 1872, but in 1911 it was upgraded to a Class 2 post office—the only one of its rank in the entire Saku region of Nagano Prefecture—reflecting Karuizawa's rising status as an international resort.
To match this new prestige, a brand-new post office building was constructed that same year on the bustling Kyu-Karuizawa Ginza shopping street. The architect was Koda Ryokichi, a railway carpenter and contractor who had just completed work on the renovation of Karuizawa Station. The new building was a Western-style wooden structure designed to harmonize with the cosmopolitan atmosphere of the resort town. It served the community as a post office and became a hub of social exchange where vacationing foreigners and Japanese alike gathered news from afar.
The building continued in service as a post office until the mid-twentieth century, after which it was repurposed in 1971 as the Karuizawa Tourist Information Center. By the 1990s, however, the structure had grown old, and in the mid-1990s it was carefully dismantled, transported to the grounds of Karuizawa Taliesin near Lake Shiozawa, and reassembled in its current location. It opened to the public in 1996 under the name "Meiji 44 Hall," chosen to honor the year of its original construction.
Why It Was Designated a Cultural Property
On April 18, 2008, the Meiji 44 Hall was officially registered as a National Tangible Cultural Property under Japan's Agency for Cultural Affairs. The recognition reflects several distinctive values that make this building stand out among the surviving Western-style structures of the Meiji period.
First, the building is a fine surviving example of Meiji-era Western-style public architecture in a highland resort context. While Karuizawa is famous for its private foreign-style villas, public buildings of this kind are far rarer, and the post office served a vital civic role in the town's development as an international destination.
Second, its symmetrical façade with a centrally projecting porch, hipped tile roof, and German-style horizontal lap siding (doitsu shitami-ita-bari) represent a refined adaptation of Western architectural vocabulary by a Japanese craftsman. During the relocation, the exterior was carefully restored to its original color scheme—the now-iconic pale mint green—based on historical research.
Third, the building is treasured alongside other Karuizawa landmarks such as the Old Mikasa Hotel and the former Karuizawa Station as one of the few surviving public-character buildings from the formative years of the resort. Together they form a precious record of how Western architectural styles took root in a uniquely Japanese alpine setting.
Architectural Highlights
The Meiji 44 Hall is a two-story wooden structure with a building area of approximately 181 square meters. The roof is hipped (yosemune-zukuri) and finished with traditional Japanese tile, while the walls below are sheathed in distinctively Western horizontal clapboarding. This combination of a Japanese tile roof with a Western timber-frame body is itself characteristic of Meiji-era public buildings, where local materials and techniques met imported design ideas.
The principal façade is strictly symmetrical. A pent roof (geya) shelters the front, and a small entrance porch projects in the center to greet visitors. The pale mint-green exterior is one of the building's most photographed features, providing a striking contrast against the deep greens of the surrounding forest in summer and the snowy whites of winter.
Inside, the ground floor now houses a pasta restaurant called Sonett, which serves seasonal dishes made with highland vegetables in a wonderfully nostalgic setting. The second floor is occupied by the Fukazawa Koko Wild Flower Museum, dedicated to the works of Western-style painter Fukazawa Koko (1903–1993), who spent more than twenty summers painting the wildflowers of the Karuizawa highlands. A reconstruction of her atelier, watercolors, oil paintings, and her personal collection are on display.
What to See and Do
A visit to the Meiji 44 Hall is best combined with a leisurely day at Karuizawa Taliesin, the resort park in which it stands. The mint-green building rewards both close-up appreciation of its detailing and wide-angle photography from across the lawn or the lake. In summer, white hydrangeas bloom around the building, creating a beautiful floral frame. Autumn brings vivid foliage, and the building looks particularly photogenic against the colors of the surrounding maples.
Inside, you can pause for a meal at Restaurant Sonett on the ground floor, where the historic atmosphere adds quiet charm to the dining experience. Upstairs, the Fukazawa Koko Wild Flower Museum offers a tranquil escape into delicate watercolors of the alpine flora that defines the Karuizawa landscape—asama-kisuge lilies, matsumushi-so scabious, primroses, and many others. A small museum shop sells postcards and reproductions, perfect as gentle souvenirs.
Karuizawa Taliesin itself spreads around Lake Shiozawa and brings together several other historic buildings, art museums, an English rose garden, and recreation facilities including rowboats, go-karts, and a cycle monorail—making it ideal for travelers of every age.
The Surrounding Area
Within Karuizawa Taliesin, visitors can also explore the Peynet Museum, the Karuizawa Kogen Bunko (Highland Literature Museum), and the relocated Suikyu-so villa once used by writer Asabuki—buildings that together tell the literary and artistic story of Karuizawa. The English rose garden is at its peak in June, while Lake Shiozawa offers gentle boat rides in warmer months.
A short drive away lies the Old Karuizawa Ginza area, where the Meiji 44 Hall once stood and where you can still feel the atmosphere of the early resort days. The Old Mikasa Hotel, another beloved Meiji-era Western-style building, sits a little further north and complements a visit to the Meiji 44 Hall as a study of early Karuizawa architecture. The Karuizawa Shaw Memorial Chapel and Hoshino Hot Springs are also worthwhile additions to a longer stay.

Q&A
- When is the best time of year to visit the Meiji 44 Hall?
- Late spring through autumn offers the most rewarding experience. June brings fresh greenery and roses in the surrounding garden, summer is the classic Karuizawa season with white hydrangeas around the building, and autumn (mid-October to early November) frames the mint-green façade with brilliant foliage. The Karuizawa Taliesin park reduces hours and some facilities close in the deep winter months, so it is best to check the official park website before visiting between December and February.
- Do I need a ticket to enter the Meiji 44 Hall?
- The Meiji 44 Hall sits within Karuizawa Taliesin park, which charges an admission fee. The Fukazawa Koko Wild Flower Museum on the second floor has its own admission as well, while Restaurant Sonett on the ground floor is open to diners. Combined tickets covering Taliesin entry plus the museums are available and offer the best value for visitors who plan to explore the whole park.
- How do I get there from Karuizawa Station?
- From JR Karuizawa Station, take the local circular bus or a Seibu bus and get off at the "Shiozawa-ko" stop, then walk a few minutes to Karuizawa Taliesin. The Meiji 44 Hall is located just inside the park, near the main gate. By taxi, the journey takes about ten minutes. By car, the park is roughly fifteen minutes from the Usui-Karuizawa Interchange of the Joshin-etsu Expressway.
- Why is the building painted mint green?
- The pale mint-green color is the building's original color scheme from the Meiji period. When the structure was relocated to its present site in the 1990s, careful research was carried out to restore the exterior to the colors used at the time of construction. The shade has since become one of the most beloved visual features of the building and a favorite photo subject for visitors.
- Is the building still functioning as a post office?
- No, the building no longer operates as a post office. It served that function for several decades and was later used as the Karuizawa Tourist Information Center. After being relocated to Karuizawa Taliesin and reopened in 1996, it has housed Restaurant Sonett on the ground floor and the Fukazawa Koko Wild Flower Museum on the second floor. A modern, separate Karuizawa Post Office continues to operate elsewhere in the town.
