The quality of this house is already amazing. Here in the united states 2 x 4s and plywood are standard for framing, walls, subfloors and the roof. The fact that plywood was only used as a temporary floor during this build says a lot about the quality. This level of hardwood and craftmanship would cost a fortune in the US. We build for effeciency and never think of quality in our builds, which is a real shame. Great work!
@@kai6424 the headers are mortised into the columns, no need for extra trimmers, this style of construction is very different than American style construction. It's more like timber framing. The screws and bolts aren't the structural weight bearing part of the house, the wood is doing that, because all the wood is bearing on more wood. Take the screws out and the house still stands. Take the nails out of an American house and it falls over.
@@Montezuma03 The screws are for seismic reason because the traditional Japanese timber frame cannot withstand the shear loading when the timber frame moves during an earthquake. The screw bolts keep the timber frame in place during an earthquake. On the other hand, the American 2x4 and 2x6 framing is slightly better in earthquake but it still require additional seismic reinforcements as we learn more about earthquake. The Japanese use timber framing because it is the traditional construction for a Japanese house. The modern timber frame, all the cuts are computerized at the factory instead of hand cut mortises and tenons. It's not better or worse, it is different and it is a traditional construction method in Japan. 2x4 and 2x6 framing is a traditional American construction. It is lightweight and serves the American house very well given it is used on millions of homes, in some of the most seismic active regions on Earth.
@@shanedevon6447 You have to give the source information because homes in Japan fell down during an earthquake. Many grand temples look pristine because many of them were rebuilt on a regular basis because of rots and other stuff so this is pure anecdotal evidence at best. Western framing is used in Japan for years but it is not as common as in the West.
@@shanedevon6447 the same thing when millions of homes didn’t collapse during decades of earthquakes in Los Angeles. Using the evidence of home collapse numbers during an earthquake to determine the seismic design difference between post and beam versus space framing is non sensical at best
@@2Phast4Rocket Western framing is used in some places because it was cheaper to produce and was sold as a way forward after WWII, which devastated housing in many areas, especially the Kobe region. It was marketed as a way to build a great number of homes in a short amount of time and at lower cost. Many of the houses being analyzed after the Great Hanshin earthquake of 1995, were in fact of newer (western) construction techniques. Many of the older buildings, as you stated, had suffered insect degradation and the fitment of heavier tile roofs. Keep in mind that pre 1980, there was no national build code. Also important to keep in mind that while earthquakes are somewhat common in some regions, others are more likely to see typhoons.. and as such are built differently. If you want a detailed analysis of traditional techniques and some of the common failures there, you can look to Professor Toyo Ito's work on the subject. He's a famous Japanese architect and recipient of the 2013 Pritzker Architecture Prize. I can summarize what little I remember but insufficient diagonal bracing, poor foundations and heavy roofs were the main modes of failure in the earthquake analysis. Probably the most extensive structural analysis group in the world is the Hyogo Earthquake Engineering Research Center (aka E Defense). Full scale building testing at true seismic level events. As you can imagine, a lot of good data analysis is coming out of this center. All of the best performing structures to date are much closer to Eastern design than Western, with adequate diagonal bracing and the like. ruclips.net/video/s1h1fBUlaH8/видео.html
I love the insight you give into older building traditions that were still around even 40 years ago. Obviously not all of them have stuck around, but it really shows how social even construction would be, and the owner personally catering a meal and drinks for their workers would be unheard of here nowadays.
The addition of the English narration is creative and fantastic. What a great innovation to your great videos in sharing your Master Carpenter skills. 👍🔨😎
Love the owner feeding and respecting the workers. This is how it should be, every contractor I've ever hired was treated like family. This house will be amazing.
Your style is very intricate yet very simple. The discipline that you employ while working is the best. Am a carpentet hobbyist from kenya i love woodworking a lot. And since i started following you av learnt and enjoyed waching you work. And hope to learn more to become better from you guys and other great carpenters around the world. Respect.
That framing is impressive. Wonderful craftsmanship. Amazing at the speed of erection. Having a solid frame essentially weathered in after 2 days of work is absolutely amazing. I am impressed with the insulation already tightly installed and essentially air tight in the roof. I wish that was more the case in our country. Our building codes don't even begin to touch this quality of construction.
The manufacturing for the posts and beams began long before the day of the framing. The timber had to be trimmed, the mortise and tenons were cut by CNC machine at the factory. They were trucked to the construction site and they are expected to be fitted perfectly since they were cut by computer.
I was working on a crew of 4 and we were framing a 2200 square foot house every week. Monday we would start installing the sill plates and the first floor joists and decking and by Friday we were sheeting the roof. All the houses were stick framed, some were 2x4 exterior walls and some were 2x6, and sometimes the roof was a bastard hip with rafters cut on site. The next Monday we would start on the next house. We weren't timber framing but it was built well.
Kind of impressive how so many of your crew have harness, even visible tethers yet are not using these personal tethers. Is that typical? Have only your reflexes and balance to protect you?
What a great video, great production, so entertaining and informative, thank you! I jolted at that young carpenter using his Makita impact driver as a hammer to tap that board 😂😂.
i love to have this kind of house 🏠, but its impossible to build that kind of house 🏠 here in Philippines .the wood material here so cozy ..plus dnt have the fabrication here for wood ..
Such a cool video. Love how you build. Any chance we could get a video on the factory that precuts all the timber ? Do they ever make many mistakes with the pre cut timber ?
Dear sir. Recently I began thinking about what happens on rainy days when houses were being erected. Do builders wait for the wood to dry? Does it affect the wood in anyway? And then you uploaded a video that I have found most informative and answered some of the questions that I had. I have no background in this field but I have always been interested in carpentry and maybe, hopefully, one day build a house. Thank you for sharing your knowledge and expertise through your channel.
Love watching you excel at your craft. I respect you and all of your coworkers and your hard work. Hearing about all the tradition is very inspiring. Thank you for sharing and I will wait patently for the next video! 😄
The framing joinery you use is amazing. Framing in the USA is not nearly as strong, both in the size of the material and the joinery methods. I wish this were available here.
The lack of nails is the most outstanding thing to me, in the US we'd be going thru thousands of nails as we framed up, these are probably crazy rigid as it is but I'm curious if they ever bother using wood glue in it's joints.
This type or framing isn't as rigid as it seems. Notice the bolts that were used to tie the beams to the posts. These are required to hold the timber in place during an earthquake. Without these bolts, the timber frame will come apart and the house will fall down.
I love the idea of having a sturdy timber frame that's a mixture of groves and long metal bolts. Is the wood treated in any way to prevent rot from being wet? or is that a non issue for this type of building? Good use of a hanging blumb-bob to level the walls. That roof looks super solid and well built too.
love how everything is a jigsaw puzzle and slips in thats great workmenship and labour, but at 4:33 , that splitting on the end grain is that going to be a problem 10 years time?
Absolutely love how this all comes together - Great job on the narration, but still giving a good understanding of the culture. Is this a typical build style in Japan, or a higher end "custom" build?
First I want to say I love the channel . That being said I don’t like the fact that they screw mostly everything. Which is not good cause screws snap well nails bend . Especially in a place known for a lot of earthquakes. On another note the amount of respect and courtesy the Japanese people have amazes me. What a fascinating culture and people .
When your standing the columns and inserting the tenon into the sill , is there a dowel added later or does it remain floating? Another great video i love watching these 😊
I would be very interesting to know how much work would be need to fix a house after earth quake ? 👀 . I live in Christchurch New Zealand with thousands of earth quakes.
If you could be so kind, could you tell me the cost of cypress in Japan? For the Grade A, no knots? I've been trying to find a reliable source for hinoki, as I build fine furniture using traditional Japanese tools and techniques, but unfortunately, all I usually find are small pieces at an outrageous price.
It is a cool video and an amazing process but I can not unsee people with security harness but not a single line attached to a safe point... or even to any point.
ONCE IN A LIFETIME. That resumes all. What an experience for the owner and sense of pride for the builder! With these feelings, it is normal that there are beautiful traditions that unite them in the process. Apart from that, how much quality of materials! One question, could you say how much would this house be from 1 to 10 in terms of quality standards (materials, insulation, type of construction) in Japan? 一生に一度。 それはそれを要約します。 所有者にとっては何という経験であり、ビルダーにとっては誇りです。 これらの感情で、その過程でそれらを結びつける美しい伝統があるのは普通のことです。 それとは別に、素材の質の高さ！ 1 つ質問ですが、この家は日本の品質基準 (材料、断熱材、構造の種類) で 1 から 10 のどれくらいになると思いますか? これはGoogle翻訳からのものです。これで十分だと思います... 😅😅
In a later video he shows how internal reinforcement walls are framed. Those are very clever designed, with diagonal bracings and a lot of hardware that give them rigidity and fix to the foundation. I guess those houses are very very sturdy at the end. 💪🏻
American inspectors would be going crazy about the crew using screws for the frame work. What do you guys think? Do you think Americans are wrong about the disallowing of screws in most frame work?
One thing that I've noticed is that you don't use levels much, it looks like you use a square instead. In the US we use levels for everything, I'm curious if you have levels and if it's just the way your trained to use a square instead of a level? The workmanship your doing is great!!!
Probably for privacy reasons, they take that stuff very seriously in Japan. Given that the framing wood was all precut at a factory, they probably labeled the material with the name of the homeowner so they know where it goes.
Imagine if an american framer bowed before starting a job!? 😂 However they would definitely start each day with salt and saki…pallets of saki for “self purification”!
That type of construction and the synchronized pounding of those large mallets would never fly here in the states because one carpenter would be looking at his phone and the other would be smoking a joint.
Now... is this true craftmanship and cares about quality and the structure. We "American" lost that value and doesn't care our quality and craftmanship such shame..
If you are interested in the (very traditional) German way to build wooden house frames, search for "Fachwerkhaus". Comparable build technique but with embedded diagonal support beams for shear reinforcement . After all Germany and Japan are in many ways similar when it comes to quality and philosophy

It was nice to see the owner of the house coming to the building site and making a connection with the carpenters.
What’s most impressive is how respectful and peaceful those workers are.
The quality of this house is already amazing. Here in the united states 2 x 4s and plywood are standard for framing, walls, subfloors and the roof.

What I love is no ego, no BS, just good work getting done.
I am 100% sure this building will be stronger then the average house made in America! I bet that building could withstand tornadoes!

It’s really good to see how much can be done by a good team of workers in just two days
A butter knife to finish the caulk. I like it.
I think westerners should go to Japan to learn this amazing craftsmanship!!

The special long screws you use are called Torx.
Thanks for sharing the awesome videos! we're just curious the lumber prices change in your country like USA
The quality of the lumber in this video is just unbelievable. I walk into Home Depot and Lowe’s and there’s nothing but shitty lumber everywhere. 😂
love how everything is a jigsaw puzzle and slips in thats great workmenship and labour, but at 4:33 , that splitting on the end grain is that going to be a problem 10 years time?
It would be nice to know, how much a house of this quality costs? I hope u are allowed to answer this question :)
I wonder what was used traditionally in Japanese houses for insulation? Just full of awe at looking the building process...
I thought it was being filmed over a couple days until he said “we’re hungry, it’s lunch time”
Absolutely love how this all comes together - Great job on the narration, but still giving a good understanding of the culture.

一生に一度。 それはそれを要約します。 所有者にとっては何という経験であり、ビルダーにとっては誇りです。 これらの感情で、その過程でそれらを結びつける美しい伝統があるのは普通のことです。
それとは別に、素材の質の高さ！ 1 つ質問ですが、この家は日本の品質基準 (材料、断熱材、構造の種類) で 1 から 10 のどれくらいになると思いますか?
これはGoogle翻訳からのものです。これで十分だと思います... 😅😅
Why is there only 70mm of insulation in the roof ? That’s a very small amount.
Mann kann es auch uebertreiben mit den guten Wuenschen.
Wow that’s like a lego set it’s already cut and ready to be put together in Canada and the us we have to frame it ourselves out of 2x4s and joists
The roof is foam, furring strips, plastic sheet, cedar boards, rubber matting, then metal? That's a lot of layers
Why dont japanese carpenters use diagonal beams in the walls? How do you achieve rigidity in your walls?

At 1:57 is that a stone base already attached to the column?
yes to locate the post and prevent it from being moved to far out of plumb
Title with thumbnail says "Framing Over Two Days Build a House Using Conventional Meth" :DDD
2 days!!!
Framing alone would cost $100,000 here with all that nice wood
So when the place swells up you won't need fasteners.
😎👍👍
One thing that I've noticed is that you don't use levels much, it looks like you use a square instead. In the US we use levels for everything, I'm curious if you have levels and if it's just the way your trained to use a square instead of a level? The workmanship your doing is great!!!
why are some parts of the beams pixelated?
Probably for privacy reasons, they take that stuff very seriously in Japan. Given that the framing wood was all precut at a factory, they probably labeled the material with the name of the homeowner so they know where it goes.
In America carpenters get drunk after work
In Japan the lumber gets drunk during work 🤣🤣
This video confirmed that we build our houses with a pile of firewoods here in Canada.
Imagine if an american framer bowed before starting a job!? 😂 However they would definitely start each day with salt and saki…pallets of saki for “self purification”!
That type of construction and the synchronized pounding of those large mallets would never fly here in the states because one carpenter would be looking at his phone and the other would be smoking a joint.
Now... is this true craftmanship and cares about quality and the structure. We "American" lost that value and doesn't care our quality and craftmanship such shame..
