Seiko Epson Founding Memorial Hall (Former Daiwa Kogyo Office): Where Japan's Watchmaking Story Began
On the eastern shore of Lake Suwa in Nagano Prefecture stands a modest two-story wooden building with whitewashed lap-siding and rows of evenly spaced windows. To a passing visitor, it might look like an ordinary mid-century office. In reality, this is the cradle of one of Japan's most remarkable industrial stories — the place where a small wartime workshop grew into Seiko Epson, the company that would later give the world its first quartz wristwatch and its first compact digital printer.
Officially registered as a National Tangible Cultural Property in February 2023, the Seiko Epson Founding Memorial Hall — formally known as the former Daiwa Kogyo Office — has been thoughtfully preserved and is now open to visitors as part of the Epson Museum Suwa. Stepping inside is like opening a time capsule of postwar Japan, and of the quiet determination that turned a lakeside town into what locals once dreamed of calling "the Switzerland of the East."
A Building Born from Postwar Resourcefulness
The building was completed in October 1945, just two months after the end of the Pacific War. It was constructed by Daiwa Kogyo Limited, a precision watch parts manufacturer founded in May 1942 by Hisao Yamazaki. With wartime shortages still gripping the country, the founders had no easy access to fresh building lumber, so they turned to an unexpected source: timber salvaged from local agar (kanten) warehouses, a regional industry once central to Suwa's economy.
The result is a structure that tells two stories at once. From the outside, the building is unmistakably Western in spirit, with a covered porch on the west side, neatly lapped wooden siding, and rhythmic bands of paired windows on both floors that flood the interior with natural light. Inside, however, traditional Japanese carpentry takes over. The roof is supported by a simple wagoya timber frame, the kind used in Japanese houses for centuries, and the floor plan reflects a practical office layout: a side corridor pushed to the west on the ground floor, and a central corridor running the length of the second floor.
The building covers roughly 193 square meters and stands two stories tall under a hipped roof of pan tiles. Its understated dignity speaks of a moment when Japanese craftspeople had to make do with what they had — and made something beautiful in the process.
From Wheel Oscillators to the World's First Quartz Watch
To understand why this small office matters, you have to follow what happened inside it. The first product Daiwa Kogyo manufactured was a tiny precision component called a "wa-furi," or wheel oscillator — the regulating heart of meteorological clocks and patrol clocks. From this single part, the company expanded into watch movements and complete timepieces.
Founder Hisao Yamazaki carried a simple but powerful philosophy: seijitsu doryoku, meaning "sincere effort." The phrase is engraved on a stone monument just outside the memorial hall today, and it became the foundational ethos of the company. Yamazaki dreamed of rooting a world-class watch industry in the Suwa basin, with its clean air, soft water, and skilled hands.
That dream came to fruition in stages. The company became Suwa Seikosha and produced the legendary Marvel watch in 1956 and the first Grand Seiko in 1960. Then, in 1969, engineers working under the same corporate lineage stunned the world with the Quartz Astron 35SQ — the first quartz wristwatch ever sold commercially. A few years later, in 1968, the team developed the EP-101, a compact lightweight digital printer that became the seed of the Epson brand. The very rooms where these innovations were planned and the early watches assembled are still here, preserved.
Why It Was Designated a Cultural Property
When Japan's Agency for Cultural Affairs reviewed the building in 2022 and 2023, two qualities stood out. First, the structure remarkably preserves the look of an emergency postwar building made from repurposed agar-warehouse timber — a vivid physical record of how Japan rebuilt itself with whatever materials were at hand. Second, the building has tangible industrial-historical significance as a monumental site marking the birth of Japan's domestic wristwatch industry.
For Seiko Epson, this was the company's first cultural property registration. For visitors, it is a rare chance to experience a place where craftsmanship, corporate philosophy, and Japanese industrial history converge under a single tiled roof.
Highlights of a Visit
The Founding Memorial Hall is one half of the Epson Museum Suwa; the adjacent Manufacturing History Museum (Monozukuri Rekishikan) houses the broader product story. Inside the memorial hall itself, three exhibition rooms unfold the company's history with care.
Exhibition Room 1 — Sincere Effort takes its name from Yamazaki's motto and follows the years from Daiwa Kogyo's founding in 1942 to the launch of Suwa Seikosha. On display are the company's first complete women's wristwatch, the celebrated Marvel — once nicknamed the "miracle watch" for its accuracy — and the first Grand Seiko, which set Japanese precision watchmaking on a world stage.
Exhibition Room 2 — Creation and Challenge recounts the company's victories at international chronometer competitions and showcases the Crystal Chronometer, a quartz clock that engineers shrank from locker-sized to portable. It captures the moment Japan moved from imitating Swiss precision to defining its own.
Exhibition Room 3 — Technology for People centers on the leap from watches to broader electronics, featuring the Quartz Astron 35SQ, the EP-101 digital printer, and the 06LC six-digit liquid-crystal quartz watch with seconds display. Together these objects tell a story of miniaturization and ingenuity that few corporate museums anywhere can match.
Beyond the exhibits, simply standing in the building is moving in itself. The exposed beams of the upper floor, the wide-plank flooring, and the soft light through the rows of windows give a strong sense of the postwar workshop atmosphere — a setting that helped shape the disciplined, detail-oriented culture for which Suwa's industries are still known.
Planning Your Visit and Exploring the Area
The Founding Memorial Hall sits on Seiko Epson's headquarters campus in Suwa City, about a fifteen-minute walk from JR Kamisuwa Station. Visits are by complete reservation only, made through the museum's web booking system, and admission is free. Tours are guided in Japanese; visitors who do not speak Japanese are warmly welcome but are encouraged to bring an interpreter to get the most from the experience. Visitors aged sixteen and older are asked to present photo identification at reception, and minors must be accompanied by a guardian.
Suwa rewards a longer stay. Lake Suwa itself is a beautiful place to walk at any season, with steam rising from hot-spring inns along its eastern shore. Kamisuwa Onsen, just minutes from Epson's campus, offers public baths and traditional ryokan stays. The four shrines of Suwa Taisha — among the oldest in Japan — are scattered around the lake, each with its own ceremonial atmosphere. The Suwa City Museum and the elegant Katakurakan, a former silk-mill bathhouse turned cultural facility, round out a satisfying day or weekend of industrial-heritage and nature-rich travel.

Q&A
- Can anyone visit the Seiko Epson Founding Memorial Hall?
- Yes, the hall is open to the public, but visits are by reservation only through the museum's web booking system. Admission is free, and tours run on weekday mornings and afternoons. Guided tours are conducted in Japanese, so non-Japanese speakers are encouraged to bring an interpreter for the best experience.
- What is the easiest way to get there from Tokyo?
- Take the JR Chuo Line limited express Azusa from Shinjuku Station directly to Kamisuwa Station, a journey of about two and a half hours. From the station, the memorial hall is roughly a fifteen-minute walk through central Suwa City.
- Why is this small office building considered nationally significant?
- It is recognized for two reasons. First, it preserves the appearance of an emergency postwar building constructed with repurposed timber from local agar warehouses, which is increasingly rare. Second, it is the birthplace of what would become Seiko Epson, making it a monumental site in the history of Japanese watchmaking and precision industries.
- How long should I plan for the tour?
- Allow about forty-five to sixty minutes for the Founding Memorial Hall alone. If you also visit the adjacent Manufacturing History Museum, plan for ninety minutes to two hours total. Combining the visit with nearby Lake Suwa or Kamisuwa Onsen makes for an easy half-day or full-day trip.
- Are there gifts or watch demonstrations on site?
- The site is a museum rather than a retail facility, so there is no on-site shop selling watches or printers. Visitors interested in Seiko Epson products can find them through authorized retailers in Japan or internationally. The focus of the visit is the history, craftsmanship, and architectural heritage of the building itself.
