Watanabe-tei is a historic estate located in Sekikawa Village, Niigata Prefecture, with roots stretching back to the Edo period. In 1954, the main house, rice storehouses, and sake storehouses were designated as National Important Cultural Properties. Additionally, its exquisite garden was designated as a National Place of Scenic Beauty in 1963. The main house features a rare "ishioki-kofubuki-yane" (stone-weighted wooden shingle roof), one of the largest of its kind in Japan. This structure is designed to withstand harsh natural environments while maintaining a stunning aesthetic. The vast grounds offer a seamless blend of historical buildings and seasonal landscapes, allowing visitors to experience the profound harmony between traditional Japanese architectural techniques and the natural world.
The history of the Watanabe family began in 1667 (Kanbun 7) when the first head, Giemon Yoshi taka, moved to this location. Throughout the Edo period, the family maintained a close relationship with the Yonezawa Domain, evolving into a wealthy farming lineage that contributed significantly to the regional economy through industries such as sake brewing, shipping, finance, and large-scale agriculture. Their high social status was reflected in their ability to receive official recognition from the Shogunate. The buildings themselves, including significant renovations in 1817, stand today as a testament to this legacy. More than just a residence, the estate serves as a vital cultural monument preserving the history of the region.

The most striking feature is the main house and its unique roof structure. The "kofubuki-yane" (wooden shingle roof) reinforced with stones is an extremely rare architectural style. Inside, visitors can observe preserved sliding doors (fusama) and paper screens (shoji) that offer a visual window into the lifestyle of the Edo period. The garden is designed as a "stroll garden" (kaiyu-shiki-teien) following the Enshu school style, embodying the philosophy of "Teiya Ichinyo"—the unity of architecture and garden. Every detail, from the intricate wood-joining techniques that use no nails to the exquisite carvings on the lintels (ranma), showcases the high level of craftsmanship of the era.
Watanabe-tei presents a completely different face depending on the season. Visitors can enjoy the fresh greenery of spring, the lush deep greens of summer, the vibrant autumn foliage, or the serene, silent snowy landscapes of winter. The seasonal changes in the garden ensure that every visit offers a new discovery. The facility is open from 9:00 AM to 4:00 PM (last entry at 3:30 PM). Please note that during the winter season (December 20 to February 20), the hours change to 9:30 AM – 3:00 PM (last entry at 2:30 PM); checking the schedule in advance is highly recommended.

To deepen your understanding of this historical space, various guide services are available. On weekends and holidays, a free guided tour is offered (10:30–11:15 and 14:00–14:45, excluding winter). A paid professional guide service is also available for 1,000 JPY per person. Additionally, seasonal events such as "New Year Decoration Workshops" are sometimes held, providing a rare opportunity to learn about traditional life and architectural techniques firsthand.
The Sekikawa Village Office is located directly in front of Watanabe-tei. For a more comprehensive cultural experience, you can purchase a combined ticket to visit the nearby "Rekishi to Michi no Kan" (History and Road Museum). There is also a combined ticket available for the "Yu-mu" day-trip hot spring facility, allowing you to pair your cultural tour with a relaxing soak. Sekikawa Village is widely known as a land of mountains, rivers, and hot springs, offering beautiful natural scenery throughout the area.
Because the grounds are vast and include gardens and historical structures, we highly recommend wearing comfortable walking shoes. As the interior features tatami mats and uneven surfaces, shoes that are easy to slip on and off are very convenient. Payments can be made via cash, credit cards, or transit IC cards. Please note that English signage and staff support may vary, so it is wise to check the official website for the latest information. We also recommend dressing appropriately for the weather, as seasonal changes can be sudden.
