Kamiyama Family Residence: A Tile-Maker's Estate on the Toki River
The Kamiyama Family Residence sits on the right bank of the Toki River, a short walk north of Kinen Bridge in central Tajimi. It is the home that a brick and tile manufacturer built for himself across the late Taisho and early Showa years, roughly the 1920s into the 1930s. Seven buildings on the grounds carry national registration: the single-storey main house, a two-storey Western-style annex, an east wing, a north wing, a clay-walled storehouse, and two smaller outbuildings standing to the north and west.
The man who commissioned it was Sato Teiji, who later took the Kamiyama name. In the early Taisho years, just as the Mino district was beginning to manufacture architectural tile in earnest, he founded the Sato Decorative Brick Works, the firm that grew into today's Kamiyama Pottery. He went on to serve as the first mayor of Tajimi. The tile factory once occupied the land directly north of the house; that ground now holds a housing showroom, a supermarket and parking, but in Sato's day it was where the tiles were fired.
The estate reads almost as a private catalogue of its owner's trade. Japanese and Western forms stand side by side across the compound, and the same family product, ceramic tile, turns up on roofs, walls and window surrounds throughout.
What the Registration Means, and Why It Is Unusual Here
The legal category is worth getting right. These seven buildings are Registered Tangible Cultural Properties, a status quite distinct from the more familiar Important Cultural Property and National Treasure designations. Japan introduced the register in 1996 to offer lighter, notification-based protection to the very large number of modern buildings that were disappearing before anyone had recorded them. Rather than the strict permit system applied to top-tier monuments, registration works through reporting and guidance, and is meant to keep useful, characterful structures in everyday use.
The Kamiyama buildings were entered on the register on 28 April 2000. They are the only registered cultural property buildings in Tajimi, a city otherwise associated with the National Treasure halls at Eihoji temple in the Kokeizan hills. Most of the seven were listed as models of their building type; the storehouse was listed under a separate criterion, as a structure not easily reproduced today.
What the estate records is a specific moment in regional history. Western Mino became one of Japan's great tile-producing areas in the twentieth century, and here that industry is told through the house of one of its founders, who furnished his own home with the goods his works turned out.
What to Look For
The two-storey Western annex is the anchor of the group and a local landmark. Its lower walls are clad in scratch tile over a stone base, with a German-textured render on the upper floor and a slate gabled roof edged in copper. The entrance, set on the west side, is finished in Japanese style, an odd and deliberate pairing. By the family's own account the works supplied tile for the Imperial Hotel in Tokyo, a claim often repeated locally and best treated as oral tradition rather than documented fact.
The main house faces south. A porch with a gabled, irimoya-style hood marks the southeast corner, a veranda runs along the south face, and a moon-viewing platform projects at the southwest. Small refinements give it away as the work of someone who could afford care: the veranda eaves, for instance, are roofed in slate rather than tile.
Linked to the main house by a covered passage, the east wing is mostly Japanese in feeling, with an irimoya roof and boarded lower walls. At its southwest end, though, a tiled room with a bay window answers the Western annex across the garden. The storehouse to the north is a two-storey clay-walled dozo: a granite foundation laid in three courses, a namako lattice-plaster wall below, black plaster above, and heavy hinged doors under tiled eaves at the gable. It is a storehouse built to be looked at as well as used.
The smaller buildings round out the picture. The north wing held the kitchen, marked by a gabled vent on its roof. The north storehouse is said to have housed the staff who ran the household, and the modest west outbuilding is described as a former live-in study; its entrance was boarded and finished to chime with the annex. Both attributions come down as tradition rather than record.
One practical point: this is a lived-in private residence and is not open to the public. There are no tours and no interior access. The Western annex can be seen from the surrounding streets and the river embankment, and that view is the proper way to appreciate the place. Visitors should keep to public ground and respect the privacy of the residents.

Q&A
- Can I go inside the Kamiyama Family Residence?
- No. It is a private home in current use and is not open for tours or interior visits. The grounds cannot be entered. The two-storey Western annex is visible from nearby public streets and the Toki River embankment, and viewing it from there is the only appropriate way to see the property. Please respect the privacy of the residents.
- How is a Registered Tangible Cultural Property different from a National Treasure?
- They are different tiers. National Treasures and Important Cultural Properties are selected as the most valuable items and protected by a strict permit system. The registration system, introduced in 1996, applies lighter, notification-based protection to a much wider range of modern buildings, with the aim of keeping them in use. The Kamiyama buildings are registered, not designated, and that distinction is part of what makes them characteristic of early twentieth-century townscapes.
- Who built it, and why are tiles so central to the story?
- It was built by Sato Teiji, later Kamiyama, founder of a decorative-brick works that became Kamiyama Pottery and the first mayor of Tajimi. He made his living from architectural tile and brick at the very time the Mino district was establishing itself as a tile centre. His own house became a showcase for those products, which is why ceramic tile recurs across its roofs, walls and window frames.
- How many buildings are protected, and which ones?
- Seven buildings on the estate are registered: the main house, the Western annex, the east wing, the north wing, the storehouse, the north storehouse and the west storehouse. Their registration numbers run from 21-0018 to 21-0024, all entered on the register on 28 April 2000. The areas range from the 142-square-metre main house down to the 17-square-metre west outbuilding.
- I am interested in the tiles. Where can I actually see and learn about them?
- The Mosaic Tile Museum in the Kasahara district of Tajimi is the place to go. Designed by the architect Terunobu Fujimori and opened in 2016, it gathers a large collection of twentieth-century Japanese tile in a building shaped like a clay-digging pit. It is open 9:00 to 17:00 (last entry 16:30), closed on Mondays, with general admission of 310 yen for adults and free entry for high-school students and younger.
