Experience countless stories in a traditional Japanese architecture accommodation with 16 rooms, nestled in Narai-juku.

Narai-juku, with a 400-year history on the Nakasendo, remains as Japan's longest post town, preserving much of its original charm. Located at the midpoint of the 69 stations of the Nakasendo, this post town flourished with many travelers and was affectionately known as "Narai Senken." As we inherit four historical buildings as the Property BYAKU Narai, we have chosen not to give each building a new name. Instead, we decided to return to the "yago" (traditional house names) passed down from the Edo period, such as calling the sake brewery "Suginomori Shuzo," established in 1793 and a symbol of the town, "Toshiyoshiya." The 16 Rooms are unique and diverse, utilizing the structures of the four historical buildings, each with different layouts and purposes. Immerse yourself in spaces that embrace the historical architecture, and experience the history and countless stories these buildings have witnessed over time. We offer a unique stay experience in these traditional houses, distinct from typical Hotel Rooms, where you can feel the essence of a place that has supported various lives and activities for generations.

  • I visited on the 17th and 18th of last week for a refresh vacation. When I arrived, there were so many people along the Narai-juku street that it was difficult to make my way in.The garden outside my Room was spacious and could be enjoyed from the floor-to-ceiling window, creating a calm atmosphere where time seemed to slow down. I was able to spend some quiet, relaxing moments.Both the food and drinks were absolutely delicious!I was also very satisfied with the dinner pairing—the selections matched perfectly.Personally, one dish featuring locally grown vegetables and the gin and tonic served as part of the pairing were especially memorable!The staff at BYAKU Narai were easy to talk to, and I really enjoyed our conversations—it became a wonderful memory.This time I missed out on trying the whisky, so next time I’d like to make sure I don’t forget. I also forgot to buy a bottle for home (haha).

  • With little prior knowledge, I made a Reservation for one night on my way back from Kamikochi. I had long been interested in renovated spaces like old sake breweries and post-town buildings, and the cuisine suited my taste far more than expected—making this an Accommodation I’d love to revisit. The team worked with great care and respect for Nagano ingredients. This time I stayed in Room 110 at Ueharaya, but next time I’d definitely like to stay in the main building, Toshiyoshiya, in a room with a semi-open-air bath. I also liked the staff’s friendly service.

Hundreds of stories residing in the region

BYAKU is a Property. But it is not an ordinary Property. It is a Property that delivers a hundred experiences rooted in the local area to our guests and preserves architecture from a hundred years ago for the future. This is the essence of BYAKU (百). If you look closely at the Japanese character for "宿" (inn), you will find the character "百" (hundred) hidden within it. When you interpret this character, you realize it holds the meaning of "a hundred homes" and "a hundred people." From this, we drew inspiration. Beneath a home of a hundred years lies the connection of a hundred people. These connections preserve the building for hundreds of years and spread the sentiments to hundreds of people. We aim to explore this timeless essence of what a Property should be. Surely, the hundreds (HYAKU) will overlap and become thousands (BYAKU). To add beautiful memories to your life, we have prepared a hundred local experiences and look forward to welcoming you.
