Kobe Weathercock House is a historic Western-style residence located in Kitano-cho 3-chome, Chuo Ward, Kobe, Hyogo Prefecture. Built in 1904 as the private home of a German trading merchant, the mansion is distinguished by its substantial red-brick exterior and the weathercock standing atop its roof. The weathercock gave the building its popular name, while it is also known as the Former Thomas Residence after its original owner. Designated an Important Cultural Property of Japan, it is one of Kobe’s best-known architectural landmarks.
The mansion was built in 1904 for Gottfried Thomas (1871–1950), a German trading merchant. It was designed by German architect Georg de Lalande in a predominantly Neo-Baroque style. Thomas named the residence Haus Rheinland, meaning “House of the Rhine.” Its imposing German-inspired exterior was complemented by interior details influenced by Jugendstil, the German form of Art Nouveau.
At the time, Kobe was an important international port, and the Kitano district developed into a residential area for foreign merchants and other expatriates. Weathercock House preserves the architectural character of this period, when Western-style residences became an important part of Kobe’s urban landscape.
In 1914, Thomas and his family temporarily returned to Germany so that their only daughter, Else Thomas, could attend an advanced school there. The outbreak of the First World War soon placed Japan and Germany on opposing sides, preventing the family from returning to their home in Kobe.
The residence is said to have been confiscated as enemy property, although the official property register records a sale during the war. The house subsequently passed into other hands, including those of businessman and politician Katsumi Yamagata. It was purchased under the name of his company, Shin Nihon Kisen, and later belonged to the Yamagata Memorial Foundation, which used it as a research facility.
In 1968, the building was sold to Kobe Chuka Dotsubun School. Its profile rose dramatically in 1977, when the NHK television drama series Kazamidori brought the house to national attention. The mansion became widely recognized as a symbol of Kobe’s historic foreign-resident district.
In 1978, the building was designated an Important Cultural Property of Japan under the name Former Thomas Residence. Kobe City acquired the property that same year and opened it to the public, allowing visitors to explore one of the city’s most distinctive historic houses.
Weathercock House is a two-story wooden building with a basement and a tower rising above its hipped, slate-covered roof. Its exterior combines different materials on each level: granite masonry at the basement, brickwork on the first floor, and half-timbered construction on the second floor. This combination gives the mansion a distinctive appearance and reflects the architectural traditions of Germany and other parts of Europe.
On the east side, an entrance porch is reached by a flight of steps, with a balcony above it. A small tower stands at the southeastern corner of the building, and the weathercock rises from the roof as the mansion’s defining feature.
The iron weathercock measures approximately 90 centimeters wide and 80 centimeters high. Designed to rotate with the wind, it indicates the direction from which the wind is blowing. It is also believed to have served a lightning-protection function and to have carried religious symbolism.
The weathercock has become one of the most recognizable symbols of Kobe’s Kitano district. Its image is closely associated with the city’s Western-style mansions and has become part of Kobe’s visual identity.
The first floor is arranged around a central hall. The study is on the north side, the living room to the south, and the entrance on the east. The dining room and a veranda occupy the west side. The arrangement reflects the domestic life of a prosperous international merchant family in the early 20th century.
The second floor contains a hall, breakfast room, bedrooms, a guest bedroom, a children’s room, a bathroom, balconies, and verandas. The rooms are positioned above their corresponding spaces on the first floor: the children’s room is above the living room, the breakfast room above the reception room, the guest bedroom above the study, and the couple’s bedroom above the dining room.
The basement contains office space, a restroom, and storage areas. Above the main floors is an attic room located directly beneath the roof’s pointed tower and weathercock. Approximately the size of eight tatami mats, the small room has a locked entrance and double-layered windows.
The original purpose of this attic room remains unknown. No records explaining its use have survived, leaving it as one of the mansion’s intriguing mysteries.
The mansion suffered damage during the Great Hanshin-Awaji Earthquake of January 1995, including cracks in its brick exterior walls. Restoration work continued for one year and eight months, after which the building was repaired and preserved for future generations.
For many years, the mansion’s completion date was generally given as 1909. However, more recent research and testimony suggest that it may actually have been completed in 1904. Evidence includes signed architectural drawings by Georg de Lalande and records left by Thomas himself.
The color of the building’s exterior timber has also been the subject of preservation discussions. When the mansion was designated an Important Cultural Property in 1978, the timber was painted gray; it was later repainted in a brownish shade. During repainting discussions in 2011, proposals were made to restore the deep green color indicated in de Lalande’s original designs, a color he used on several other buildings.
The mansion entered a period of closure for seismic reinforcement work on October 1, 2023. The project was scheduled for completion by the end of March 2025, with the aim of improving the building’s safety while preserving its historic character. Visitors should check current information before planning a visit, as opening arrangements may change.
Along with Kobe Port Tower, the Kobe Maritime Museum, and the historic buildings of the former foreign settlement, Weathercock House is one of the landmarks that represent the city. Its distinctive silhouette is a familiar symbol of the Kitano Ijinkan district, where Western-style mansions preserve the atmosphere of Kobe’s international past.
For visitors interested in architecture and history, the mansion offers an opportunity to discover how foreign merchants lived in Kobe during the early 1900s. Its combination of German architectural influences, richly designed interiors, and a memorable rooftop weathercock makes it one of the city’s most distinctive historic buildings.
