- Japanese House No. 2 - Timber Frame Construction Series - "Tatemae" - July 2021
In this series, we are in Machida, Japan where we are participating in a new Japanese house build. The house design is based on a very traditional Japanese building style. The architect, chose a more classic design with his client and utilized a lot of natural land features to help increase the comfortability of the house itself. The positioning of the house along side a hill provides cool air during the summer months and a protection from too much loss of heat during the winter months. It is difficult to juggle the somewhat extreme climate fluctuations in Japan. The hot and humid summer months and cold and dry winter months are equally as long and difficult to comfortably adjust to.
House Information:
Land Area: ~436.18 sq. meters (~132 tsubo) (~4695 sq. feet)
Building Area: ~105.29 sq. meters (~32 tsubo) (~1133 sq. feet)
Total Living Area: ~134.66 sq. meters (~41 tsubo) (~1450 sq. feet)
1st Floor Area: ~92.54 sq. meters (~28 tsubo) (~996 sq. feet)
2nd Floor Area: ~42.12 sq. meters (~12.74 tsubo) (~453 sq. feet)
The house has a two stories with the common living area situated on the first floor. The 1st floor has a large 12.5 tatami great room and a dining, kitchen, and tea area are adjacent to the large great room. Also downstairs is a full bathroom with the toilet room separated. There is an outdoor terrace space that faces the hillside which will provide cool and shade during the summer months. The second floor is available space for rooms or storage. This house is designed for communal family living where all members of the family will reside in the same room.
In Part 2 of the House No. 2 build, we are continuing the raising of the timber frame from the second floor to the roof. The joinery starts to get more difficult as there are several pieces that need to slide perfectly together in order to set a wooden pin.

Japanese Craftmanship = Perfection.
The house was made with the utmost respect from the carpenters. The work isn't rushed. They take their time to measure everything for it to be perfect.
This is so beautiful! it makes my heart happy that there are still people in the world who care about their work so much and have such attention to detail.
Makes you want to have the privilege to attend such a wonderful teaching
Yes
This is a more solid build that will last for centuries. It reminds me of the old structures in North American that were of a pole and beam style and many of these homes are still being used. This style of building does so much better in strong storms.
Impressive. I love the way they did that scarf joint on two round and very irregular beams at the 2:30 mark.
I can not thank you enough for this series of Japanese wood work…
Priceless!
Due to the solid nature of the construction, I doubt very much that here will be creaking floors or steps in the structure when it is completed. They aren't just slapped up like in the US utilizing flimsy studs or excessive nail gunning. These are very precise builds done with pride and craftmanship. I especially enopyed them using the larger levels too.
@@mstrdiver Exactly my thought. Houses like this could be standing firm after ten (twenty?) US houses have fallen and been rebuilt.
ditto - it is so fascinating
Amazing craftsmanship; if I were younger I would want to work with these guys. I could learn so much!
Great !
Beside all the theories behind these building process, I just love how respectable they are at work. It's a work that not only need brute strength but also precise thinking and experience.
In North American, we welcome with f word before even work starts 😅
Their so accurate they don’t need and center ridge lines perfect 👍
Beautiful to watch this beauty coming into shape!
Nice work very good. Be carefull guys
One thing that jumps out to me is how clean that lumber is. Straight and furniture quality. Compare those 2x4 in this video vs the dimensional lumber you get in Home Depot or just any construction site in North America.
Japan has cedar tree farms, and they trim the branches everyday to make them grow straight and true, those lumber are worthy enough to be used as pillars in Japanese temples
@@pihermoso11 i wish we could smell through TH-cam
"One thing that jumps out to me is how clean that lumber is. "
It has to be. Japanese homes are premanufactured and arrive at the job site in kits. If they ship a warped piece of lumber then the builder has to ship it back and wait for a replacement.
My same thoughts. The reason is yellow pine grows faster and is cheaper but ugly.
I think maybe you're comparing this home to the mass-produced homes here in the USA.. Watch videos on American post and beam builds, they will much more reflect more this level of production. Additionally, this home you're seeing, if built in the USA would cost 1.5 mil or more to build, so you can see this is no "normal' home.
Thank you for another great instalment that virtually brings me there to the build site. Nice animation on the Nuki joint!
Glad you like it! The Nuki information was difficult to explain, but I hope the animation simplified the explanation. Thank you for watching!
I really wish I could work with you guys and learn this. Looks incredible
Truly beautiful work and a super structure.
Great video. I'm in Japan now from the states. About to get some tatakinomis ! All thanks to you and your videos
Have fun!
Wow!!!
Interesting work, it’s good to learn from other cultures and ways! 👍
This usnby far one of the best build I have seen interested in more if possible
We have a lot to learn from Japanese housebuilding, absolutely stunning. I would love to have my house built be these professionals who take pride int heir work and deliver top notch quality. I really love the Japanese sense of perfection, it turns into art in the end. Simply great!
These guys inspire me to be a better person, to have dedication to something like they do is a rare thing indeed. I will learn from their attitude 🙂
"We have a lot to learn from Japanese housebuilding"
No we don't. American homes are the highest quality homes in the world. Our building standards produce homes that last 100+ years. Japanese homes are disposable and only last for 30 years. At 15 years they have no value at all.
Japanese carpentry is really cool, but modern japanese homes are disposable and don't come anywhere close to American homes in terms of quality.
@@jimbeam-ru1my are you claiming this house they're building will only last 30 years?
@@jimbeam-ru1my
The reason Japanese houses last only 30 years is because Japan has high humidity, which has a great effect on wood decay. Also, termites like high humidity, and they parasitize and eat the trees that make up the house, which is the cause of hastening the deterioration of the house. However, with high airtightness, high heat insulation, and good ventilation, it is possible to keep it for more than 30 years. Some wooden structures in Japan have been preserved for over 1000 years. It all depends on the maintenance of the people who live there.
By the way, most of the houses made by major Japanese housing construction companies are disposable because they are prefabricated in a factory and then assembled locally. However, the current situation is that there are other small and medium-sized building contractors that have adopted the construction method shown in this video.
My dream is to build just a small cabin with Japanese woodworking principles ❤
That is amazing
looks like a forever home going up one timber at a time
leap away, clueless troll
Wunderbare Arbeit !
This is beautiful work! The precision. .. They are adjusting things down to the millimeter. Here in the US, its good enough if its within a foot or two of where it should be. On the flip side, we can frame a multi story house beginning to end in an afternoon.
amazing. you guys are building building as furniture. Our carpenter here only shoot hundreds of nails in connections.
I think I was Japanese in my past life. I have been chastised over and over "we're not building cabinets, it ain't gotta be perfect"
Nothing pisses me off more than hearing that on a jobsite. Like sure it doesn’t HAVE to be, but it definitely makes a difference and people will notice
@@erk9822 exactly! I remember names two ways - one, when the construction impresses me; two, when the construction pisses me off. And I will talk about the construction that impresses me to anyone wanting to know a good person for the job. But I will talk about the construction that pisses me off _by name_ to anyone who will listen.
Or when they say “can’t see it from my house “ how many times have you heard that?🤣🤣
Typhoon proof for sure.
Garrett, you are doing something wonderful here - please keep it up. I hope you will take some time to create more 'how to' videos away from work. I'd love to know more about the details of the Japanese carpentry work that you are learning (for example) what are the marks that a Japanese carpenter would put on a beam (for example) when laying out a mortice? I'd also like to know more about the Japanese names for 'things', cuts, joints, tools etc.
Very soon, I will be working on learning more about Sumitsuke (墨付け) or marking the wood with ink to draw the profile of joints in the near future. I hope to go more in depth with other videos. Thank you for watching.
6:43 I assume no glue in between those half lap joints?
Is this a traditional build or how most homes are built in Japan? Either way its beautiful! Almost like a fine peice of furniture.
This is a traditional build and the majority of Japanese housing is prefabricated unfortunately. Yes, it’s beautiful. Thank you for watching!
Love you videos, I have one question on this one: at 4:04 you have a illustration of how to use nails to lock the Nuki in place. I don't understand how the nails are placed, it seems they are next to the Hozo-ana or inside the gap. Could you explain? Thanks a bunch and keep making these videos!
I love the construction style of the wood work! I noticed that you had a pencil holder on your helmet. Where can I find some of them?
Major wood working skills here! Never seen anything like this. But I’m wondering how this will hold up in an earthquake? Is there any flex in this type of construction?
You guys are master Carpenter love watching I noticed the level could you please give me the brand ? Or one day make an episode of complete carpentry that you use every Day? Thank you by the way for sharing this is precious ,😃🙏🏻
Thank you very much for such a valuable information about japanese carpentry. I like the canal because you give us access to details and practical side of the work to foreign people don´t understand Japanese.
Can you recommend a book in English that covers the practical information about japanese carpentry frame construction?. I mean, I´ve read some books about japanese carpentry or archiquecture but they are more teorical, general or visual than practical.
Again, thanks a lot.
Thank you for watching. I can't recommend any books at the moment. I have been learning from the other carpenters daily and I try to look through some of the Japanese textbooks that are out there. There is one book called "Wood Joints in Classical Japanese Architecture" by Sumiyoshi and Matsui which has a lot of pictures of the joinery with dimensions. The book also talks about the common places in a structure that this joint would be used. There is also some information about the failure of the joint with diagrams explaining their failure test done. Also, "the Complete Japanese Joinery" by Sato and Nakahara is a pretty good reference that covers some of the joinery and also has information about wood selection, workshop spaces, and tools. I hope this helps.
I know one book about traditional japanese house construction called 'Minka'.
Love these videos 👍. What size chisels are being carried around?
Normally for the Tatemae you will see a mix of chisels from 15mm to 30mm. However, most carpenters will bring their normal chisel roll with the full set of chisels in the event that there needs to be major rework done. Thank you for watching.
Such beautiful craftsmanship. I truly admire Japanese carpentry. What types of wood are being used?
In Japan, the most common wood used are Hinoki (Japanese Cypress) and Sugi (Japanese Cedar). For round beams called Maruta a Japanese Pine is used.
@@thecarpentrylife do they do much sho sugi ban anymore? I was surprised to see where wood and concrete or stone came in contact that those spots weren’t sho sugi ban.
@@thecarpentrylife Chamaecyparis obtusa and Cryptomeria japonica? Pinus thunbergii (Japanese Black Pine), Pinus parviflora (Japanese White Pine) and Pinus densiflora (Japanese red pine), which one do they use the most?
I really enjoy this video as much as the last part ! haha
It's really awsome to compil all that knowledge and technical terms !
I have 2 questions :
At 5:18 min, we can see some grrove on the wood, for what purpose ?
And at 5:23 min, there is one vertical pillar, the closest. He has a perfectly flat fit ... Why they don't cut the pillar to perfectly take the forme of the maruta ? He could be offer a better structural support, no ?
Thanks again for everything :)
Thank you for the kind comment.
To answer your questions:
At 5:18 mark: the groove and dado are 30 mm wide and designed to fit the 30 mm thick tongue and groove floor boards (made from Sugi (Japanese cedar)) that will be installed later. The use of 30 mm wide is common in Itakura style architecture. This particular house build is a mix of different eras of Japanese architecture.
At 5:23 mark: the Tsuka (束) or vertical strut (short pillar) in the foreground hasn't been settled into position yet. Sometimes to help facilitate the joining of the roofing beams some of the pillars are left loose until ready to be hammered down with the roofing beam. As the house settles and the joints are squeezed together you will not see any gaps. In addition, it is easier to cut into the Maruta and make it square to fit the square pillar than vice versa or cutting the profile of the Maruta to the pillar. Typically the top sides of beams showcase less joinery intricacy as the underside which would be visible by the homeowner.
I hope this answers your question.
Thank you for watching. I will try to capture the reasoning for a lot of these details in later builds. The reasons for doing things are often kept in the mind of the carpenter which is sometimes difficult to extract.
@@thecarpentrylife Yes, yes, of course and you do a great job ! Sure, it's not easy to capture all explanations of them work ...
I understand well, thanks to this explanations ! :)
I just saw your 6 videos at Hayama, i will jump on it right now ! hahahah
Hope to see the next video soon ^^
Oh, yes, in 2022, i will work with Takami Kawai, a Japanese carpenter, do you know him ?
He created Suikoushya (翠紅舎), a school to learn traditional Japanese woodworking
Is there any video that shows the cut guy? I sort of wanted to see how they are measuring and cutting.
There are so many lines of cracks, doesn't it take down the structure's integrity?
Hello, are the woods used in the construction of the house not receiving any kind of treatment? And what type of wood is being used?Regards from Brasil!
what kind of wood did they use for the beams, its very beautiful wood. I like the red coloring.
Much of this house was Sugi (Japanese Cedar) and some of the showcase pillars are Hinoki (Japanese Cypress). The main pillar of this house is made of Cypress and has no knots which is pretty rare due to its size.
Has anyone done a comparison between US and Japanese building techniques where they look at the longevity of the structure vs the cost of construction? My first guess would that with all these joints this would hold up better to the environment and age compared to the US construction but then I think well.... does it? Actually detailed analysis would need to be done to get a real answer. It definitionally looks better but does it preform perform better. We would also need to define "preform better".
It's beautiful but I can't see the structural optimisation here.... there is a lot of wood for little living space.
❤
This is an incredible venture. I am curious about a detail. About 9:40 into the video,
I see what appears to be a caged plumb bob. May I have more detail about this tool?
Thanks, Michael Leake, U.S.A.
Hi, thank you for watching. So the tool you are referencing can be found explained in another video. Check out this video: th-cam.com/video/o3PhH9VFmZQ/w-d-xo.html around the 5:35 mark. This tool is an extremely convenient tool for squaring a structure. They are expensive, but I believe they are worth the expense as a home builder.
So then for the nuki they're using nails? I thought that as the metal has a different expansion coeficient as the wood, they weren't using nails or screws...
[9:16] Is it normal to have all the cracks in the big beams 🤔
I did take lots of pictures of our raising when I could but never took any video. I regret that a great deal now.
🙌🙌🙌🙌🙌
1:30 that pile of beams would cost a fortune in the USA
What kind of wood is that? It looks like cedar.
would love to see watch in sequence, detail, full, if possible, with video length extended more than 40-50 minutes, video end so fast,,,
i love these videos' but they use Japanese language without translate thank u for ur explanations
At 1:08. Is that a level with an integral plumb bob?
Yes, it is a specialized tool with a plumb bob inside.
I can't find a hozo saw anywhere can you give me a brand name for it?
Most common brands for Hozo Kiri are Ryobi, Makita, and Hitachi.
Hi there, what is the brand of the 4 saw blades machine , please !!
Thanks
I typically see 3 different brands: Ryobi, Makita, and Hitachi.
This is traditional building correct? so this isn't typical for all Japanese structures? I'm sure they have many houses built more identical to how they are built in the US. This seems very expensive and time consuming.
Are all houses there built this way?
Unfortunately no...
In America the crew would be 3 guys lol
丸太梁上の束はひからないのですね
What are these shoes called, where can I buy them?
These shoes are called tabi(足袋)
Compare that to the sticks and plywood junk we build in the US
En el idioma japonés no se dice ok
Is there anyway I can intern with you guys? I don't have to be payed, if you give me a place to stay and some food I would love to work for you. I am an American self-employed carpenter and I would love to learn about how to build structures like this.
I hear you. You would need to get a working visa otherwise we can’t provide you with one.
That warning is silly. If the Japanese are renowned for accuracy
Japanese are very good in job but wood have life span ,with time wood rot, with time joint become loosen because of rotting of wood. Try to keep wood safe much as we can by using coupling or 90 degree angle or additional triangle support .
We must work on support system which will work during 9 degree earthquake.
Jay bharat.
Traditional architecture like this is extremely expensive and cannot be built by the general public. Most ordinary houses are two-by-four buildings.
And not a single screw or a nail was used that day...
Why do you play music over the sounds of work? It would be better to hear the work then some music over top it.
I am so impressed. I love watching Japanese carpenter's craftiness.: honto. Here in the USA 😂I have to endure Julio and Jose and all the excrement wood work they do that looks not even 1% in quality to these gentlemen at work. Wish I could hire Japanese carpenters to build my next home.
That's a very expensive house......
Talk about culture that actually cares about the techniques and longevity of their creations. Im in the US where cheap labor and cheap materials to maximize profits is king, ...:/...wack.
This kind of construction is only affordable for millionaire elites and government. If it's government, how much tax needs to be collected to pay for this? There are some public works that deserve this extravagant expense but not many. Taxes are too high just about everywhere I look. High taxes can create a permanent poverty class.
The checks in this material passing through the mortis just seems wrong. 8:49. Sa a regular western carpenter, I would reject these pieces of improperly seasoned timber as would the building inspectors in Seattle. There is some fancy joinery happening here but the lack of seasoned knowledge (and seasoned timber) is disturbing. I hope the architect/designer is smarter than this.
Impressive accuracy but not worth the effort.
haha put that against american framing.. 🤣
I know a lot of you think that this is a fantastic job which it is if it was sourced from the renewable sustainable forest, becue all this timber that was used is like a small forest that had to be cut down for one little house, they could have built a concrete slab for the first level and saved a ton of wood I know that Japan has a lot of trimmers so the house needs to flex, other materials such as steel can do that and for just a2 story building it can be built on a moving slab that will take lateral movements a save all these trees that they cut, I know a lot of people don't understand the value of trees and how we really need them. yes the carpentry work is great and craftmanship is there but at what cost, if you built several of those it would mean the destruction of forests, and that lowers our carbon emissions and creat oxygen ---- so thumbs down for this project
