A commitment to lifelong craftsmanship
Our representative is determined to remain an active on-site craftsman for life. Working on site every day enables a genuine connection and mutual understanding with clients.
The ability to understand wood
When renovating old shrines, temples, or traditional homes, we must anticipate how long-assembled timber will twist when dismantled and determine whether old coatings are pigments or dyes. Work must begin only after careful consideration of such factors to avoid irreversible damage.
Traveling worldwide to build
Hanamasu's craftspeople travel worldwide to build Japanese wooden architecture. We undertake Japanese-style renovations of overseas offices, hotels, public facilities, embassies, gardens, residences, and apartments.
Corporate clients: collaborations welcome
As carpentry subcontractors, Hanamasu's master carpenters handle carpentry, construction management, and coordination of plumbing, electrical work, and delivery of residential equipment. Our understanding of the entire process allows smooth additional estimates, cost calculations, and timber procurement, making us ready to contribute on site.
Lectures for clients (free)
We hold client lectures sharing important information for creating valuable new buildings. In an enjoyable, accessible 1-hour session, participants learn about miyadaiku skills, practical wood knowledge, architectural history, academic perspectives, and legal considerations.
Our commitment to shrine and temple architecture
A landmark for 100 years into the future
Hanamasu's carpenters create beautiful, strong buildings each day with centuries ahead in mind. We continue refining our craft, envisioning a future in which these buildings remain loved by local communities and someday become a source of national pride.
3 essential conditions for proposing valuable buildings
Reassuring support from construction law specialists
Refined, beautiful, timeless designs by architects
The finest carpentry skills and ability to bring ideas to life
Only when these 3 conditions come together can a client's dream take shape.
Where carpentry skill shines
What beauty cannot be shown in drawings?
Hanamasu's carpenters faithfully inherit advanced traditional layout geometry and timber joinery, and refine their understanding of wood and use of planes and chisels every day. The delicate flowing curves cannot be captured in drawings: this is where miyadaiku craftsmanship truly shines.
Above all, before being a carpenter, one must remain a person with a sincere and pure heart. Humility and this purity of heart give rise to beautiful forms. This too is beauty that drawings cannot show.
Shrines and temples that house deities and Buddhas are crafted with advanced miyadaiku skills and, above all, a pure heart, proper attitude, and positive spirit. This gives them an unseen, dignified beauty. Though buildings, these halls become more than objects: they are places brought to life by miyadaiku hands, living alongside their communities for years to come. Their beauty emerges through use by worshippers—the highest expression of functional beauty, and the beauty of true quality and value.
Could what you truly want to achieve be something beyond a building?
What clients truly wish to achieve is often more than a building. At its root is the value of using it or a vision of the future: a place where people gather smiling, a peaceful refuge, a space to share feelings, mark life's memories together, preserve what has been inherited, or strengthen and spread shared beliefs. What do you truly hope for? Take this opportunity to think together and share those hopes with Hanamasu's carpenters.
A carpenter's deep love of wood
At Hanamasu Mokko, you can specify the origin of your timber. We seek sacred wood from places important to you—local forests, Mount Fuji, or the region of your head shrine or temple—and incorporate it into your building.
Sustainable use of wood
When old timber that supported a main hall has fulfilled its role, or trees on site must be felled for development, we preserve their precious life by turning them into furniture, pillars, or charcoal for the new building as part of our sustainable use of wood.
Hanamasu's history
Mokko in Hanamasu Mokko expresses our commitment to crafting with wood. Hanamasu is the longstanding trade name of a family business making floral ornaments for shrines and temples, founded in Kan'ei 17. Its current representative is the 14th generation of Hanamasu in Asakusa, Tokyo, carrying on the family's spirit of craftsmanship as a miyadaiku carpenter.
The importance of a dedicated miyadaiku carpenter
Does the relationship end at completion?
Shrines and temples are beautiful buildings whose character deepens with use and age. Completion is not the end of a wooden building's story; it marks the true beginning of the relationship between clients and miyadaiku carpenters.
We often hear from clients who hired distant shrine and temple builders and then struggled to arrange maintenance or small jobs. Choose miyadaiku carpenters in Kanagawa and Tokyo to preserve your buildings for years to come. Always nearby, we can respond promptly with hand tools, 24 hours a day, 365 days a year.
Our representative loves wood and carpentry and intends to remain a craftsman for life, carefully maintaining the shrines and temples he has worked on. He visits sites daily, works with his own tools, and checks every detail. This close personal relationship offers lasting reassurance.
Want to rebuild but unsure where to start? The 1 way to resolve the problem
Have years passed without construction funds or prospects for a construction committee or other preparations? There is 1 way to move forward: take the first step. Consult Hanamasu Mokko about turning long-held hopes and ideas into action. Our ability to think alongside you toward the same goal, together with specialist, architectural, and legal knowledge, the psychology of well-being, and examples of completed projects, will be essential support.
Hanamasu Mokko offers free lectures for worshippers and organizations, with an enjoyable 1-hour introduction to achieving an ideal shrine or temple on a limited budget, and bus tours exploring wood through forestry and sawmilling. Our specialist knowledge also draws on the psychology of well-being to help people gather at shrines and temples, providing useful insights for the future. Every long journey begins with a single step.
One Team Cost, Simple Cost
A carpenter's discerning timber selection avoids waste, and our manager's role as a craftsman eliminates unnecessary management costs. Where possible, we hire local or congregational craftspeople in ten trades: carpentry, stonemasonry, plastering, roofing, carving, gardening, scaffolding, joinery, tatami making, and electrical and plumbing work. Those involved continue supporting the building for years—a practical, resourceful use of local materials and skills.
Avoiding waste also makes pricing simple. Hanamasu Mokko provides valuable buildings using quality materials while keeping costs simple. We consider your budget from your perspective and propose solutions as one team working toward the same goal.

TRAINING
Miyadaiku training that becomes second nature
Hanamasu Mokko Shaji Kenchiku's miyadaiku training program, where real miyadaiku skills become second nature.
Not "teaching and learning" but making it "second nature".
A hands-on miyadaiku training curriculum
Thousand-year skills for the next thousand years
We are neither a timber merchant nor a sawmill. Hanamasu goes directly into the forest to choose timber on site — the "ability to see through wood" — and generously passes on to young craftsmen our experience of building around the world.
We position creating an environment for training young people as our top priority and devote ourselves to training new miyadaiku.
Our training curriculum is hands-on.
Because our curriculum is hands-on, real miyadaiku skills become second nature. What matters most is awakening a "feel" by making skills second nature rather than "teaching and learning".
Traditional apprenticeship, handed down since ancient times, has become practically impossible, and in the Heisei era the number of companies training craftsmen from scratch fell sharply due to the recession. As a result, wooden construction specialists have decreased sharply and Japan's advanced traditional wooden construction skills have declined markedly.
In addition, the turnover of young miyadaiku is high and the training of wooden construction specialists is declining. To reverse this, we run training that passes on authentic miyadaiku skills directly from active master carpenters, the ability to respond case by case on site — the most important skill for a miyadaiku — and communication and perseverance as a craftsman and a person before being a working adult.

TOURISM
Miyadaiku tourism with a master carpenter
A special program to experience the world's oldest wooden construction skills
FY2021 Agency for Cultural Affairs certified project
Selected for the Agency for Cultural Affairs' project to add high value to cultural assets to promote visits to Japan by travelers seeking high-quality tourism services
This program was selected as a project promoted by the Agency for Cultural Affairs to create high-value tourism content using Japan's cultural assets. Its purpose is to let travelers from Japan and abroad experience the world-class skills of miyadaiku.
What is a miyadaiku?
A carpenter who builds and restores shrines, temples and palaces — repairing buildings built hundreds or thousands of years ago and passing them on to the next era. It is one of the most sacred professions.
A miyadaiku's work is not mere construction. It creates places that serve the gods and Buddha and gives shape to people's spiritual home. It demands facing wood, accepting the laws of nature, and both reliable skill and deep spirituality.
Miyadaiku tools
Chisels, planes, carpenter's squares and other tools used by craftsmen for many years
The miyadaiku's perspective
A craftsman's view that sees not only buildings but people's hearts
Spending time in history
Skills from 1,400 years ago are still alive today
Miyadaiku story
In the Man'yo era, the way of Shikishima was said to be the way of waka poetry. Like flower arrangement and tea ceremony, some ways have formal schools yet are widely practiced.
Yet in the world of miyadaiku, who have long served the gods, there is still no name for such a way, because this skill has always been handed down "for the gods and Buddha".
The handwork of these craftsmen shows a world opposite to modern architecture. Fitting wood to wood and erecting buildings without nails — this skill has survived 1,400 years and is still alive today.
Why miyadaiku tourism now?
The world's oldest wooden building, Horyuji. Its history goes back about 1,400 years. Many of the world's other oldest wooden buildings are also Japanese shrines and temples — why?
The secret lies in Japan's unique wooden construction skills: shrine and temple structures with intricate wood carvings, and buildings still standing after hundreds of years. Behind these mysterious skills are miyadaiku techniques registered as UNESCO Intangible Cultural Heritage "Traditional Skills".
The miyadaiku's work can be called the world's oldest full-scale business. Letting people today experience those skills and that spirit — that is "Miyadaiku Tourism".
Registered as UNESCO Intangible Cultural Heritage "Traditional Skills"
The miyadaiku's perspective
"Do not speak of temple halls without revering the gods and Buddha"
The most important perspective of a miyadaiku begins with the resolve to build shrines and temples. The gods and Buddha say nothing, but these are places people rely on, feel at ease in and turn to.
We cherish this wish to "build a spiritual home". Here lies the high spirituality of miyadaiku. Building shrines and temples is also building people's hearts.

VOICE
Feedback from miyadaiku experience participants
It was a rare opportunity to learn directly from a master miyadaiku carpenter. The feeling of shaving wood, using tools, and the spiritual side of architecture—I experienced things with my whole body that books could never teach. Discovering the depth of traditional Japanese architecture has inspired my continuing interest.

HANBARA
Why our workshop is in Hanbara, a center of miyadaiku craftsmanship
Skill and spirit carved into Hanbara, the sacred land of miyadaiku
Hanbara, in Aikawa Town, Aiko District, Kanagawa, has long been known nationwide as a renowned home of miyadaiku carpenters. Hanamasu Mokko keeps its own workshop in this sacred land of miyadaiku, which has supported many historic buildings, and continues to face traditional craftsmanship with sincerity.
Japanese wooden architecture nurtured in the sacred land of miyadaiku
The name Hanbara holds special meaning in the history of Japanese architecture. Countless master carpenters left this small mountain village to build and restore shrines and temples across the Kanto region and throughout Japan.
The spirit of the craftsmen still lives on in Hanbara today.
The history of shrine and temple architecture nurtured in Hanbara
Behind Hanbara's prosperity as a home of miyadaiku lie its rich natural environment and historical geography.
【Abundant, high-quality timber】
Blessed with the rich forests of the Tanzawa Mountains, the area produced plenty of hinoki and cedar ideal for shrine and temple architecture, and craftsmen learned from childhood to touch wood and judge its character.
【Close ties to centers of faith】
Being close to centers of mountain worship such as Oyama Afuri Shrine, famous for the Oyama pilgrimage, and the renowned Shorakuji Temple, the area naturally called for advanced woodworking skills.
The techniques refined by craftsmen in this environment spread, mainly in the Edo period, beyond Kanagawa to the whole Kanto region and on to the building and restoration of shrines and temples across Japan.
Legendary master carpenters and the exquisite Hanbara carving
No account of Hanbara's miyadaiku is complete without the Yanai family, including Yanai Seikichi, revered as ancestors of carpentry, and the craftsmen around them. The essence of the skills handed down by Hanbara's miyadaiku lies in two great features.
【Kumimono: bracket joinery that is strong and beautiful】
Traditional joinery that withstands earthquakes, wind and rain continues to support buildings across centuries. This technique of fitting timbers precisely together without nails was refined to the limit by Hanbara's craftsmen.
【Hanbara carving, full of depth and passion】
Exquisite wood carvings vividly adorn the kohai porches and ranma transoms of shrines and temples. Their delicate, three-dimensional beauty still leaves its mark on many cultural properties, shrines and temples today.
Why Hanamasu Mokko keeps its workshop in Hanbara
Hanbara is a sacred land that produced many master carpenters and where the history and passion of shrine and temple architecture run deep. Hanamasu Mokko keeps its own workshop here to inherit the craftsman's spirit and genuine skills that flow through this place and pass them on to the next generation.
【An environment alive with history and skill】
In the workshop, surrounded by Hanbara's clear air and history, skilled miyadaiku do uncompromising handwork from judging timber to shaping it.
【Inheriting and practicing traditional techniques】
From marking and cutting carefully selected timber to traditional woodworking and carving, craftsmen who inherit the DNA of the masters keep honing their skills every day.
【Fusion with modern technology】
Alongside traditional techniques, we actively combine modern seismic and reinforcement technology to deliver reliable shrine and temple architecture suited to changing times.
The focus and pride that only a special place like Hanbara can draw out are poured into every shrine and temple building Hanamasu Mokko creates.
Shrine and temple architecture that lasts into the future, through traditional skill
Protecting historic traditional techniques, and building and restoring reliable shrines and temples suited to changing times.
From our workshop in Hanbara, the sacred land of miyadaiku, Hanamasu Mokko will continue to deliver heartfelt joinery and shrine and temple architecture.
