The preservation of Japan's built cultural heritage has extraordinary allies in Billy Dillon and Adam Miller of Kominka North America
We are thrilled to share that the preservation of Japan's built cultural heritage has two extraordinary new allies and advocates in Billy Dillon and Adam Miller of Kominka North America! We met Billy and Adam on the Timber Framers Guild Spring Tour in April and are delighted to have the opportunity to join forces going forward. Billy and Adam bring a vast and diverse wealth of experience in carpentry and the building trades. United by a deep commitment to craftsmanship, they share a passion for both traditional and innovative construction techniques. Their global journeys have allowed them to learn from experts in regional carpentry traditions across countries including England, France, China, Sweden, Germany, and Japan. Billy's career began with an apprenticeship in the carpenters' union, and over the course of 50 years, he has worked extensively in both residential and commercial high-end construction. He has also shared his expertise by teaching courses on stair building, tangent handrailing, and eyebrow dormers, in addition to judging carpentry competitions at SkillsUSA. Adam, mentored by the pioneers of the North American timber frame revival, has been a key figure in the field. Since 2018, he has edited Timber Framing, the quarterly technical journal of the Timber Framers Guild. More of Adam's work and publications can be found at www.adammillercarpentry.com.

Kominka North America and Uncarved Block Inc. give a beautiful kura a second life as part of a timber framing woodshop
Our wonderful new partners, Billy Dillon and Adam Miller of Kominka North America, were in Shinshiro in early November to disassemble an extraordinary structure. This 130-year-old kura was once the storehouse for a silk mill, but some years ago part of the roof broke and began to leak, making preserving the kura difficult. The building was going to be torn down in December, but Billy, Adam and Brad Morse, owner of the timber framing company Uncarved Block, came to the rescue. The kura will be rebuilt to become part of Uncarved Block Inc’s new timber framing workshop space. We have all been hoping for a way to save this gorgeous structure, and that this is happening is really something. Heartfelt thanks to Kominka North America and Uncarved Block Inc! This kura is an exceptional structure due to its beautiful joinery and large size. While in rural settings or smaller villages, kura were often built to store grains, tools, or other agricultural products, these were typically around 6 meters in length and 4 meters in width. For wealthier families or merchants in towns or cities, kura would be larger to accommodate larger quantities of goods, including precious items like silk or rice. These might reach lengths of 10 to 12 meters or more. The kura from Shinshiro is 27 meters in length, making in a particularly large structure. Like other kura, this storehouse had thick, fire-resistant walls and a robust, functional design, with thick earthen walls, a tile roof, and small windows and heavy doors: Kura doors are often made of thick, heavy wood and sometimes reinforced with iron, making the structure more resistant to break-ins or natural disasters. Historically, kura storehouses were an essential part of rural life in Japan, often found on farms, merchant properties, and in towns. Today, kura continue to be admired for their craftsmanship and resilience, embodying traditional Japanese building techniques that prioritize durability, functionality, and aesthetic harmony with the natural environment.
Two weeks of exploring Japan's traditional building arts with the Timber Framers Guild Fall Japan Tour
The Timber Framers Guild Fall Japan Tour was a carefully crafted journey through Japan's rich architectural and cultural heritage, with a particular focus on traditional woodcraft, joinery, and sustainable building practices. From November 7th to 21st, a group of timber framers, carpenters, and woodworking enthusiasts explored the country's finest examples of craftsmanship, both ancient and contemporary, immersing themselves in the unique world of Japanese architecture and timber construction. Tokyo: The Beginning of the Journey The adventure began in Tokyo, one of the most vibrant cities in the world, blending the ultra-modern with the traditional. The group was welcomed and oriented in this metropolis, where they set the tone for the tour by diving into the roots of Japan's architectural traditions. Kigumi Joinery Museum A highlight of the Tokyo leg was a visit to the Kigumi Joinery Museum. Kigumi is a traditional Japanese carpentry technique used in timber framing, involving intricate wooden joinery that requires no nails or metal fasteners. The museum offered a deep dive into this ancient craft, showcasing both historical examples and modern applications. Visitors had the opportunity to observe tools, techniques, and exhibits on the intricate ways timber was worked to build homes and temples in Japan. Asakusa Area The group also spent time in Asakusa, one of Tokyo’s oldest districts, known for its traditional atmosphere. Walking through its ancient streets, they explored the famous Senso-ji Temple and enjoyed the blend of old-world charm and lively shopping streets, where artisans still practice their craft. Onsen Experience After days of exploration, the group unwound at a serene onsen hotel. Soaking in the healing waters of a traditional Japanese hot spring was the perfect way to rejuvenate before moving on to the next leg of the journey. Odawara Castle and Kezuro-kai Annual Competition Next, the tour ventured to Odawara Castle, a historic fortress that showcases traditional Japanese construction techniques and timber-frame architecture. Here, the group learned about the defensive engineering and historical significance of Japanese castles. The tour continued with a visit to the Kezuro-kai Japan Annual Competition, a premier event celebrating the art of Japanese woodworking. Participants had the chance to see master carpenters and artisans demonstrate their incredible skills, competing in various disciplines such as joinery, traditional timber framing, and woodworking. Kyoto: The Heart of Traditional Japan After a journey through the modern and historical realms of Tokyo and its surroundings, the group traveled to Kyoto, the cultural heart of Japan. Chisetsu Temple Stay & Morning Chanting The group stayed at Chisetsu Temple, a tranquil location that provided an authentic, immersive experience. They had the rare opportunity to witness early morning chanting by the temple’s monks, an awe-inspiring ritual that resonated deeply with the participants and set the tone for their continued exploration of spiritual and architectural traditions. Path of Philosophy & Kawai Kanjiro's House The group wandered the Path of Philosophy, a scenic walk lined with temples and natural beauty. Along the way, they visited the house of Kawai Kanjiro, a renowned ceramic artist, where they learned about the intersection of traditional craftsmanship and art in Japanese culture. Tool Shops and Temples A series of visits to traditional tool shops introduced the group to the tools and materials used by master craftsmen in Japan. They also explored various temples and sites of architectural interest, gaining insight into the symbiosis of religion, craftsmanship, and design that defines Japan’s built heritage. Day Trip to Nara: The Ancient Capitals One of the most memorable excursions was a day trip to Nara, Japan’s first permanent capital. The group visited Todaiji Temple, home to one of the largest bronze statues of Buddha in the world, and the Horyu-ji Temple, a UNESCO World Heritage site known for its ancient wooden structures and architectural significance. Kobe: Takenaka Carpentry Museum The group then traveled to Kobe to visit the Takenaka Carpentry Museum, a stunning institution dedicated to the history and evolution of Japanese carpentry. Here, they learned about the tools, techniques, and materials used in traditional carpentry and timber framing, including how Japanese artisans approach precision and joinery. Miyama Village: Roof Thatching & Traditional Kominka Miyama Village, a picturesque area known for its thatched roof kominka (traditional farmhouses), offered a unique glimpse into sustainable building practices. Led by Haruo Nishio, a master thatcher, the group learned about the art of roof thatching—a time-honored practice that involves weaving straw to create weather-resistant roofs. They also spent two nights in Haruo Nishio’s beautifully restored kominka, gaining firsthand experience of life in these traditional homes. Sustainable Forestry Walk with Sachiko Takamuro A key part of the tour was an educational sustainable forestry walk with expert Sachiko Takamuro. This excursion emphasized Japan’s innovative practices in forest management, highlighting the balance between human activity and environmental conservation. The group learned about forest stewardship and how timber framing in Japan aligns with sustainability. Kumiko Master Shinichi Murayama A visit to Shinichi Murayama, a renowned kumiko artisan, provided an opportunity to see this intricate form of Japanese woodwork in action. Kumiko involves creating delicate latticework patterns from thin wooden slats, a technique that requires immense skill and patience. The group observed Murayama at work and explored his philosophy behind this beautiful and intricate craft. Workshop with Ryosei Kaneko & Jay van Arsdale The group participated in a hands-on woodworking workshop led by master carpenter Ryosei Kaneko and Japanese woodworking expert Jay van Arsdale. The workshop focused on traditional Japanese woodworking techniques and offered participants the chance to create their own pieces, guided by these two experts. Hoshino Shrine & Kominka Preservation The tour then visited Hoshino Shrine and spent a day with award-winning temple designer and builder Shigetaka Mochizuki. Mochizuki shared his philosophy on temple design and the traditional methods he uses to create sacred spaces. The group also toured various kominka, including one that was relocated from Niigata to Aichi and is now the office of Toda Komuten, a leading architectural firm specializing in traditional buildings. A tour of vacant kominka led by Toda Komuten introduced the group to the challenges of preserving and restoring these historic structures. Participants learned how these buildings are repurposed while maintaining their architectural integrity. Yakisugi and the Art of Wood Preservation One of the more unique demonstrations was the yakisugi process, also known as shou sugi ban, a traditional technique of charring wood to preserve it against the elements. The group watched as artisans demonstrated this ancient method, which imparts both beauty and durability to timber. Yoshihiro Takishita: Father of Kominka Preservation In Kamakura, the group had the privilege of visiting Yoshihiro Takishita, known as the father of kominka preservation. Takishita’s three beautifully restored kominka exemplify the commitment to preserving Japan’s architectural heritage. His work continues to inspire a new generation of architects and carpenters dedicated to keeping traditional building techniques alive. Farewells in Tokyo The journey concluded with farewells in Tokyo, reflecting on the experiences, knowledge, and insights gained throughout the trip. Participants departed with a deeper understanding of Japan’s building arts, an appreciation for the precision and beauty of Japanese woodworking, and a renewed commitment to sustainable and traditional craftsmanship in their own practices. The Timber Framers Guild Fall Japan Tour was an unforgettable exploration of craftsmanship, culture, and history—an enriching experience for anyone passionate about timber framing, woodworking, and traditional building techniques.
Yamayoshida Shrine Theatre was going to be torn down. We hope to find a home for the beautiful dismanlted frame and materials.
This 85 year old structure was a theatre on the grounds of a shrine built in 1649 in a very pricturesque mountainous area of Shinshiro in Aichi Prefecture. The theatre building is shown next to the shrine in the photograph and was a place where people in the village gathered and various events were held – on our initial visit, hula dancing was listed as the first performance listed on the program for a community gathering. As a theatre, it had few posts to support the roof and a high ceiling, making it easy to use as a large open space. Japanese shrines are built of Japanese cypress and cedar, not pine. Therefore, most of the materials used in this building are cypress. It is in good condition, with some restoration having been done to some of the columns and beams. As the shrine theatre was going to be torn down, the decision was made to disassmeble it in the hopes that someone would give it a new home in Japan or overseas. Its frame and other materials are now kept in the Toda Komuten’s Nagara storehouse. This past year we are extending the range of structures we are trying to save to include a range of other traditional buildings as more and these structures are also also being torn down. Among those that we are currently trying to relocate to save are a temple, two temple gates, a temple keeper’s house, a small shrine, two barns, a kura storehouse, and several exquisite portable teahouses made of very old yakusugi - as well as a number of kominka and already disassembled frames, such as the Yamayoshida Shrine Theatre, and materials.
Zen House Kominka in beautiful Wallowa County, Oregon is described by owner Kiyomi Koike as "a Japanese tea house where you can stay."
In 2021, the owners of what is now the “Zen House Kominka” guesthouse, Kiyomi Koike and Bill Oliver, learned that Eric Carlson, a Kominka Collective board member, was rebuilding a minka on his property ten miles down the road from where they live. Kiyomi san is a tea ceremony teacher and the founder of Sei Mee Tea, a company selling Japanese green tea. She sold the company last year, but at that time she was hoping to have a small tea house on her property to use for tea ceremonies and as a space for quiet reflection. The timing was somewhat serendipitous as, having successfully sent Mikawa House to Wallowa County, Oregon, we were already planning that our next step in this project would be to create a 200 sq ft “minka studio” in Japan – as a kind of kit - and send it to Oregon to be assembled for use as non-residential structure that, as such, would not require planning permission to build. As it turned out, this was exactly the type of small space that Kiyomi san was looking for. The studio was designed with input from members of our team, with details worked out over numerous Zoom calls across time zones, and then crafted in Japan using new and old materials by carpenters at Toda Komuten. For various reasons, we were fortunate to be able to use Japanese cypress for much of the studio, and this certainly adds to the beauty of the structure. As with Mikawa House, we packed the studio and all types of furnishings and fixtures – including an old ladder to reach the loft area, shoji screens, decorative ceramic roof tiles, doors, tansu, new windows, and new roofing material - into crates which went into a 40 ft container, and we sent it on its way to a beautiful setting near the Wallowa Mountains of northeastern Oregon. Minka Studio arrived in early October 2022 and was assembled and completed over about a month by members of our team and a few kind and curious friends – although Eric spent a few more months doing finishing work on his own, including the interior and exterior plastering as we were concerned that the plaster might crack enroute to the US were we to do it in Japan. Being Oregon and being October, an early snow added a certain unexpected excitement to the reassembly process. During the planning of the Minka Studio, Kiyomi san decided that she wanted to extend the structure to make it a place where people could stay and where, as a certified life coach, she could hold wellbeing retreats in the calm setting of a kominka. On the Japan side, we found a small kominka that was going to be torn down, was the right size, and had a wonderful beam structure, and disassembled it and carried out the work in the workshop to prepare to send it to Oregon. This minka, which we referred to as Obu House due to its original location in the town of Obu in Aichi Prefecture, was approximately 90 years old and had at one time been surrounded by rice fields and vegetables patches. When we visited the minka, the town had closed in around the house and it was essentially a farmhouse in a somewhat urban setting in a rural area. During the visit, the owner and her adult son kindly showed us around the house. At that time, no one was living there, but furniture and various furnishings, as well as decades of memories - the family altar, ceramic vases, and other beautiful items that one would expect to find in an old folk house - were still in place throughout the house. We asked the owners how they felt about a house that had been home to their family for decades being disassembled and sent to Oregon, and they answered that they were so delighted and grateful that the minka and many of its furnishings would be given another life. When we left, the owners generously insisted that we take some lovely small decorative items from the minka’s tokonoma altar area with us to remember our visit, and we gratefully did so. It was wonderful having the opportunity to spend time with the owners of Obu House and it is equally wonderful knowing that, thanks to Kiyomi san and Bill san, the key elements of the house have a second life as a space for mindful reflection. Nothing could be better. Returning to the topic of the second phase of the Zen House Kominka project, as one might imagine, logistics of how to connect the two structures in a practical and aesthetically pleasing way, specifics of the design of the second structure, and details regarding planning permission were worked out over many hours of Zoom meetings. Designing this second structure with the aim of attaining permission to build required some strategic thinking outside the box, and now, going forward, we are more confident about knowing how to approach this. We are also keen in the future to use more reclaimed materials in traditional and modern ways, keeping the principle of “mottainai” – nothing going to waste – closely in mind during all stages of the planning and building process.
Visiting barns & kayabuki kominka in Miyama
We went to the Miyama area in late August and spent a wonderful day visiting really gorgeous old naya (barns) with Haruo Nishio san - who we had the pleasure of meeting at the 2024 Minka Summit - and his friend Kobayashi san. Impossible not to fall in love with the naya in the first slide right? A truly memorable day and just wow are we impressed by all that Nishio san is doing to preserve minka and other structures in this area. Kobayashi san's eggplant tempura and roasted chestnuts were also unforgettable! After seeing some really lovely naya, we went to a few of the kayabuki kominka that Nishio san has recently renovated. Again - so impressed by all the amazing things he is doing to save kominka and so excited that we will stay at some of his futon & breakfast accommodations with our good friends from the Timber Framers Guild in November as part of the TFG Japan Fall Tour. Just down the hill from this minka, a short walk, Nishio is turning another lovely old structure into a restaurant. "What kind of food are you going to serve?" we asked. Nishio replied that he is not yet sure. But, that's the thing, right? Save the minka first and figure out the rest next. Just so darn inspiring.
Rebuilding Mikawa House in rural Wallowa County
Alarmed by the loss of Japanese folk houses and other traditional structures, we decided to try to send the frame and other parts, materials, and furnishings of a 120-year-old kominka to Oregon to be reassembled and rebuilt. In doing this, we wanted to find out if this was possible, with the hopes that sending kominka that are going to be demolished abroad might be a way of giving them a new life. We also hoped that this would be way to give people outside of Japan opportunities to learn about and enjoy these extraordinary structures as private and public spaces, and that this might then also contribute in some way to a greater awareness and appreciation of their value back in Japan. The first kominka that we sent overseas, the 600 sq ft Mikawa House, was carefully disassembled and wooden parts were numbered so that we would know their location when we rebuilt it in its new location. The disassembled house was taken to the Toda Komuten workshop where the wooden components – beams, posts, ceiling panels, and other parts - were washed, along with 800 ceramic tiles which had been affixed to the roof with mud. The house was preassembled in the workshop, repairs made as needed, and we packed the parts into 14 crates. With Mikawa House we sent shoji screens, ranma, tansu, kurado and other doors, and an array of old and interesting items that would have been destroyed had Mikawa House been demolished – including silkworm pallets that had been in the attic, two pack saddles, scrolls, and a number of other items. To our surprise and delight, when people learned that Mikawa House was going to Oregon, they gave us any number of treasures to send with her, and it pleased us knowing that this lovely small house would begin its new life together with so many familiar items. Once in Oregon, the Mikawa House frame was assembled over the course of a day with guidance by Kunito Niwa, who had documented the disassembly of the house. The owner, Kominka Collective member Eric Carlson, has been rebuilding the structure between his other projects, and it is likely to be completed in December 2024. As is the case with kominka that are relocated within Japan, Mikawa house is being built using new and old materials. As many of the original materials as possible are being used in the rebuilding, although sometimes in new and creative ways – such as ceiling panels being used as wainscoting. The structure has been designed to meet building codes and requirements regarding insulation are met or exceeded.
A 350 year old temple gate will find a new home at a Zen Buhddist Temple in the mountains in Oregon
These lovely onigawara and roughly 500 roof tiles will be sent together with this 350-year-old temple gate to be part of a Zen Buddhist temple in rural Oregon. The temple gate here in Japan was set along a busy city street, and we like to think the onigawara will enjoy their new life fending off evil and bringing good fortune to their new home in a peaceful wooded area deep in the mountains.
