Former Igarashi Dental Clinic: A Taisho-Era Gem on the Old Tokaido Road
Standing along the historic Tokaido highway in Kambara-juku, the Former Igarashi Dental Clinic (旧五十嵐歯科医院) is a striking example of Japan's early 20th-century architectural experimentation. This two-story wooden building, registered as a National Tangible Cultural Property in 2000, seamlessly blends Western exterior styling with traditional Japanese interior design — a fascinating hybrid known as giyōfū kenchiku (pseudo-Western architecture). Once a functioning dental practice and private residence, it now serves as a public cultural facility where visitors can step directly into the Taisho and early Showa periods.
Historical Background
The building's origins predate the Taisho period, when it stood as a conventional machiya (townhouse) along the old Tokaido road in Kambara, a post town that had flourished since the Edo period. In approximately 1914 (Taisho 3), the owner Hitoshi Igarashi — a graduate of Tokyo Dental College (now Tokyo Dental University) — returned to his hometown and converted the family residence into a dental clinic. To project an image of modernity and medical professionalism, he commissioned local carpenter Genkichi Yoshida to redesign the exterior in Western style while preserving the traditional Japanese interior layout.
The building underwent further expansions: the west wing was added around 1918, and the east wing followed around 1940–1941, gradually forming the unified Western-style facade visible today. The dental practice continued until approximately 1970, after which the building served as a private residence before eventually becoming vacant. In 1998, the town of Kambara purchased the land, and the Igarashi family generously donated the building. After earthquake-proofing work completed in 2000, it opened to the public in 2001 under the management of the NPO "Association to Preserve the Former Igarashi Residence."
Why It Was Designated a Cultural Property
The Former Igarashi Dental Clinic was registered as a National Tangible Cultural Property on September 26, 2000. The building earned this distinction for its unique architectural character: it preserves the floor plan and spatial organization of a traditional Tokaido post-town machiya while presenting a thoroughly Western exterior. The hipped tile roof features large glass windows that flood the interior with natural light, while the remaining wall surfaces are finished with horizontal clapboard siding. Decorative elements such as cornice moldings and dentil ornamentation along the eaves of the main entrance and the west wing frontage add refined Western accents to the structure.
This kind of hybrid building — where a local craftsman adapted Western architectural vocabulary to a pre-existing Japanese framework — provides invaluable evidence of how international influences were absorbed and reinterpreted in small-town Japan during the Taisho era. The building's total floor area of approximately 199 square meters encompasses a remarkably complete record of early modern provincial life, combining domestic, commercial, and medical functions under one roof.
Architectural and Cultural Highlights
The Western Facade
From the street, the clinic presents a clean, modern appearance with its light-colored clapboard walls and generous glazing. The facade was designed to convey the trustworthiness and sophistication associated with Western medicine — a deliberate choice by Dr. Igarashi to distinguish his practice in this small post town. The old-style signboard, rendered in pre-war kanji characters, remains in place above the entrance.
The Japanese Interior
Step through the entrance and the atmosphere shifts dramatically. The interior retains the spatial character of a traditional machiya, with tatami-floored rooms arranged along a corridor. Lavish fusuma (sliding door) paintings and intricately carved ranma (transom panels) — including one depicting Mount Fuji and pine groves — demonstrate the wealth and taste of the Igarashi family. A VIP waiting room on the second floor, adorned with particularly fine decorative elements, once hosted distinguished visitors including Count Mitsuteru Tanaka, a Meiji-era statesman who later served as Minister of the Imperial Household.
The Second-Floor Dental Office
The upstairs dental treatment room offers a remarkable window into early 20th-century medical practice. Original equipment, including a period dental chair and technical instruments, remains in situ. The room features large south-facing windows that provided the natural light essential for dental work, with the floor finished in light blue linoleum — a distinctly Western touch within the otherwise Japanese building. Dr. Igarashi ingeniously installed a pump system to bring well water up to the second-floor treatment room, an impressive feat of engineering for a time when Kambara had no public water supply.
The Garden and Storehouses
Behind the main building, a traditional Japanese garden unfolds with a central well topped by a hand-operated pump. Two substantial storehouses (kura) stand at the rear of the property, still housing historical artifacts from the clinic's operational years. The garden also features a distinctive square-shaped Goemon-buro (traditional iron bathtub) with tiled upper portions — an unusual design that reflects the doctor's refined sensibilities. Visitors can also discover a telephone booth with the number "23" painted on its wall, a relic from an era when a district needed 25 subscribers before telephone service could be established.
Hand-Blown Glass Windows
The second-floor study room preserves original hand-blown glass panes from the Taisho era. These slightly wavy, imperfect glass panels possess a unique transparency and subtle distortion that modern machine-made glass cannot replicate. They are among the building's most treasured details, casting a soft, shimmering light that evokes the atmosphere of a century ago.
Visitor Information
The Former Igarashi Dental Clinic is open to the public free of charge. Volunteer guides from the NPO "Association to Preserve the Former Igarashi Residence" are on hand to offer detailed tours of the building, sharing stories about the Igarashi family and the history of Kambara-juku. No advance reservation is required for individual visits.
Opening hours vary by season: from March through October, the building is open from 9:30 AM to 4:30 PM, and from November through February, hours are 9:30 AM to 4:00 PM.

The nearest station is JR Shin-Kambara Station on the Tokaido Main Line, from which the clinic is approximately a 10- to 15-minute walk northwest along the old Tokaido highway. Visitors arriving by car can use the Tomei Expressway Shimizu Interchange, followed by a 20-minute drive toward Fuji. Limited free parking is available in the Kambara-juku area.
Surrounding Attractions
The Former Igarashi Dental Clinic sits at the heart of Kambara-juku, a remarkably well-preserved Edo-period post town that is the only settlement in Shizuoka Prefecture designated as a Historic National Road. A leisurely stroll through the neighborhood reveals numerous points of interest.
Just a short walk away is the Hiraoka Honjin Site (West Honjin), where the original palanquin stone and storehouse recall the days when feudal lords rested here during their sankin-kōtai processions. The Former Izumiya Rest House, a jōhatago (high-class inn) dating to the Tenpō era (1830–1844), has survived earthquakes and centuries to display its distinctive second-floor lattice railings. A stone monument near the old highway commemorates the famous ukiyo-e print "Kambara: Night Snow" by Utagawa Hiroshige — one of the masterpieces of the Fifty-Three Stations of the Tokaido series, notable for depicting this warm coastal town blanketed in snow.
For nature lovers, Gotenyama Park offers panoramic views over Suruga Bay and is celebrated as one of the region's finest cherry blossom viewing spots each spring. The ruins of Kambara Castle, a mountain fortress built by the Imagawa clan and later besieged by Takeda Shingen in 1569, provide both historical atmosphere and scenic hiking. Nearby Yui, the adjacent post town, is famous throughout Japan for its fresh sakura ebi (cherry blossom shrimp), available at local restaurants overlooking the harbor.
