How Churches, Hotels, and Villas Shaped Karuizawa's Landscape

Last updated: 2026-07-15

Pixel-art imaginary scene of How Karuizawa's churches, hotels, and villas changed use and owners, from the Former Mikasa Hotel to Raymond's own villa, sourced

The buildings that remain in Karuizawa cannot be explained by style alone. Who used them, and how their roles kept changing, shaped this cultural landscape.

The Former Mikasa Hotel became a government office and then an occupation-forces facility; the former Konoe villa changed hands three times and was relocated twice. Many of Karuizawa's surviving buildings do not stand today in the form they were first built.

This article traces three building groups, hotels, churches, and villas, not as a catalog of styles but through how their use and their users kept shifting over time, with sources throughout.

Hotel Buildings as Traces of Modernization

The Alps Wing became a cultural property while remaining in active use as lodging, while the Former Mikasa Hotel passed through hotel, government, and occupation-forces roles before becoming a cultural property.

The Mampei Hotel's Alps Wing

1936, Registered Tangible Cultural Property

The Alps Wing, the Mampei Hotel's surviving Western-style building, was completed in 1936, designed by architect Kume Gonkuro. It was registered as a Tangible Cultural Property in 2018. From 1976 to 1979, the Lennon family made Room 128 in this building their regular summer retreat. Even as it has continued operating as a place to stay, the building itself has accumulated historical value in its own right.

The Former Mikasa Hotel's shifting roles

1905 to 2025

Planned by businessman Yamamoto Naoyoshi and designed by architect Okada Tokitaro, the Former Mikasa Hotel was completed in 1905, with construction overseen by Sato Manpei of the Mampei Hotel. Meiji-ya Co. acquired it in 1925, operated by its subsidiary Chuotei, and the hotel suspended operations in 1944 because of the Pacific War. In 1945 it housed a Karuizawa office of the Ministry of Foreign Affairs, and in 1947, under occupation, it served as a rest hotel for officers of the US Eighth Army. After the occupation ended in 1952, it reopened as 'Mikasa House,' and in 1974 it was moved 50 meters north on rollers and repaired. It was designated a national Important Cultural Property in 1980, and structural renovation work including seismic reinforcement proceeded from 2020. One building kept changing roles, from hotel to government office to occupation facility and finally to cultural property.

Buildings Raymond Left Behind

Antonin Raymond left Karuizawa buildings serving very different purposes: a church and his own villa-office.

St. Paul Catholic Church

1935, designed by Antonin Raymond

St. Paul Catholic Church in Kyu-Karuizawa was founded by the English priest Father Ward, with its design handled by architect Antonin Raymond. Its exterior, marked by a steeply pitched triangular roof and exposed concrete, projects a presence distinct from the resort's villa architecture, one particular to religious buildings.

The Karuizawa Summer House

1933, Raymond's own villa and office

The Karuizawa Summer House was designed and built by Raymond in 1933 as his own villa and office. It is known for its distinctive butterfly roof, sloping down toward the center, in a wood-frame building partly two stories tall with a sheet-metal roof. Ramps and double-height openings create a sense of movement and openness inside, and it is regarded as a pioneering example of wood-frame modernist architecture using traditional Japanese techniques. It was relocated to its current site in 1986 and designated a national Important Cultural Property on September 25, 2023.

The People Behind Karuizawa's Villa Architecture

The former Konoe villa, Muro Saisei's villa, the Hatta Villa, and Meiji 44 Hall each survive today in a different form.

The Former Konoe Fumimaro Villa (Ichimura Memorial Hall)

Built by Amerika-ya, passed through several owners

Now known as the Ichimura Memorial Hall, the former Konoe Fumimaro villa was built by the construction firm Amerika-ya and first owned by Nozawa Genjiro. Konoe Fumimaro purchased the villa in Taisho 15 (1926), and in 1932 Ichimura Kesazo bought it and moved it to Minamihara the following year. In 1997 it was relocated again, to its current site at the eastern end of Amemiya-ike pond, and on May 24, 2016 it was designated a Karuizawa town cultural property. The hall now displays materials related to Konoe Fumimaro and Amemiya Keijiro.

The Muro Saisei Memorial Hall

Built in Showa 6 (1931)

The villa used by the writer Muro Saisei was built in Showa 6 (1931) and is now open to the public as the Muro Saisei Memorial Hall. Muro Saisei spent every summer here until 1961, the year before he died. It is an example of a single villa building shifting roles, from a private summer residence to a memorial hall for a writer.

The Hatta Villa's architectural details

Wood-frame, two stories, an irregular facade

The Hatta Villa, known as the first villa built by a Japanese owner, is a wood-frame, two-story building whose facade became irregular because of the shape of its original lot. When it was first built, it had neither electricity nor running water: water came from a well on the grounds, and light came from oil lamps. The stone jizo statue in the garden is said to have washed down from upstream during the great flood of 1910. The building was donated to the town of Karuizawa in fiscal 2014.

Meiji 44 Hall, a story of preservation

Former Kyu-Karuizawa post office, relocated to Taliesin in 1996

Meiji 44 Hall, relocated and restored at Karuizawa Taliesin, was originally built as the Kyu-Karuizawa post office. It was constructed by railway carpenter Koda Ryokichi, who also worked on rebuilding Karuizawa Station, and was relocated and restored at Taliesin in 1996. Centered on Lake Shiozawa and gathering a garden, an art museum, and historic buildings, Taliesin has also become a place that gives retired buildings a new home.

FAQ

Why does Karuizawa have several buildings by Antonin Raymond?

Architect Antonin Raymond built the Karuizawa Summer House in 1933 as his own villa and office. Because an architect with such deep ties to the area also designed a church building, St. Paul Catholic Church, several works in different styles survive here together.

The Mampei Hotel's shift from a wayside inn to a hotel is covered in a separate article, 'How Karuizawa Outgrew a Nakasendo Post Town,' and the organizations and commercial figures behind resort culture are covered in 'Who Built Karuizawa's Summer Resort Culture?' This article focuses specifically on the buildings themselves and their changing uses.

Can I get current admission fees or opening hours for these buildings?

This article covers architecture and changing use; it does not include pricing or opening-hours information for active facilities. Please check each facility's official information directly.

How did Mount Asama's eruptions affect these buildings?

The volcano's landforms and eruption mechanics are covered in a separate article, 'How Mount Asama Shaped Karuizawa's Water and Forests.' This article keeps its focus on architecture and changing use.
