I've never seen such a clean construction site before.

It's really awesome to have a native English speaker and professional Japanese carpenter do thiels kind of content. Thank you! Hope you keep going.

I'm impressed by the concrete work. Never seen such perfection of angles and finish on a foundation.

The only time you see this kind of detail in a structure in the US is when a timber frame carpenter builds their own house. It’s really beautiful.

Just wanted to let you know as a Japanese dude, I've learned a lot from your video. I applaud you for getting into these industries infamous for the rigid traditional ways and your boss for the flexibility in accepting you as an apprentice.

I'd love to see how that foundation was poured. A variation of only 5mm in height is impressive.

The wood material itself is already a work of art. Nicely done!!! 👍👍

Japanese carpentry is amazing. So much precision and care goes into every part of the frame. Unlike Australia where dozens of errors are fixed with extra nails or an offcut or not at all.

Having began my adult life building houses and now in IT here in the US, I can say with authority that my crew would have screwed up the hold down fastener itself from step one, and it would have gone downhill from there. That was 40 yrs ago when we had apprentices, so it terrifies me how bad it is today. I am impressed on so many levels- starting at the formwork/finish for the concrete- stunning!

the craftsmenship and precision is unmatched compared to other countries, shows also alot of respect for the client

I love seeing the modern construction materials blended with the traditional proven carpentry and joint cuts. You guys do great work.

Very impressed by the precision I see here. Wish American builders routinely took this level of pride in their work.

12:30 WOW! That has to be a mountain of maths to get all that to meet up properly in the end! I've built a LOT of modular structures with similar connections before and I've NEVER put all the pieces in place and locked down BEFORE the connecter that joins them. Wow! Intense respect for doing this this way...the precision coordination required across multiple people or even whole crews to do this like this is astounding to me. We have a hard time here just finding someone to clear trash in a proper manner...wow.

The amount of thought and careful work that goes into this is amazing, i want to buy the house just from seeing this

This is one of the most satisfying videos I think I've ever watched. I think you have to have done a little bit of building to understand just how difficult it is to get all of the pieces of this project to fit together so smoothly. The concrete foundation has to be poured to such tight tolerances, the curing and milling of those wood beams has to be done so perfectly, the measuring of the bolt locations has to be literally perfect, the hand drilling of the bolt holes has to be spot on along perfect along two axes, and the joints have to be cut so, so precisely... I mean, just looking at those toshibashira joints waiting to receive the corner posts makes me break out in a sweat, I would never attempt anything like that because my cuts would be slightly off and the post wouldn't fit. So freaking impressive.

We been to a construction site a few years ago, where many of 'us' constructors felt it was way over complicated and rather slow paced (just doing the foundation can easy take up days, we wrap it up in max a day), the sheer accuracy is basicly mesmerizing. The entire process from concrete pooring (plus groundwork) to the skeleton structure is all measured down to milimeters, no wiggle, no slack, it fits insanely tight. Though we mostly build fully concrete (walls, foundation) wich have a huge margin due to hardening, their buildprocess is considerable longer (we done tops 12 months, often less, where avarage japanse house can go 1-1,5 years), it really is a quality over quantity story. I hope to visit US sites this or next year, we in Europe just have a complete different material/construction approuch that such insane accurate measurements are just 'brushed away' with some extra drywalls and we accept nothing is perfect (they showed us a room that was to the mm 420x420mm, where ours done often vary upto 1-3cm each side).

This is cabinetry level carpentry on a house foundation, amazing!

It opens my heart to see the value put in the work and the product. Respect to japan people from Germany!

its insane how straight you drill with such long drill bits

👏🏼🌳🏠 The craftsmanship and attention to detail in traditional Japanese construction is truly impressive. It's inspiring to see how the foundation beams, or Dodai, are carefully laid out and leveled to create a sturdy base for the building. It's a shame that we don't see more of this kind of precision and care in modern construction, especially in the US. This video serves as a reminder of the beauty and value of traditional building techniques.

Thank you for documenting and sharing your hands on experiences; truly enjoyed learning Japanese home building joinery techniques

REALLY great info, and vid and craftsmanship, interesting mix of modern and traditional, and little western with Japanese. Really cool bro

You are such a brilliant teacher and film maker: really excellent, clear, concise explinations. I was already interested in the subject matter but your films really increase my interest, thank you.

丁寧で綺麗な仕事をする大工さんたちだなあ。日本の大工さんでもこういう建前が出来る大工さんはどんどん減っているので貴重です。

Really cool video. Japanese carpentry has always mistified me and the way everything just fits together. Wonderful stuff.

The joinery really caught my eye, and the care taken in marking and drilling the anchor bolt holes for what appears to be sill plates is just fascinating to me. Artisan joinery requires very accurate measurement, marking and experienced craftsmanship all of which I witnessed in this video. Learned something about chestnut which I didn't know. Outstanding work. I am glad I found this video.

Change the title to "American carpenter en Japan" and will increase to 7 millions of viewers in two weeks! A job well done! congrats!

if you ever decide to return the states, i can see you leading massive workshops teaching framers who have clients interested in this type of construction. this content is one of a kind

"Measure twice, cut once" doesn't make enought justice to your work guys. Beautifull carpentry!

thank you for explaining important matter. in the case of a Nuno-Kiso (布基礎)/Beta-Kiso (べた基礎), Dodai (土台) is bolted to the concrete foundation. in the case of a Ishiba-Date (石場建て), stone foundation will be Hikari-Tsuke (光付け).

The attention to detail of how the wood lines up with the anchor rods to make the frame perfectly flush to the edge of the slab is so nice. American construction companies would just let it be crooked with gaps and overlaps 😂.

Japanese wood work is another lvl. New favorite channel.

Foundation assembly was the first video I watched on your channel. Every part of the process is interesting and you do a great job going into all the relevant details. Hope you guys are having a nice weekend.

Absolutely incredible precision and pride in that foundation

This is really Hand crafting a building. Since my early youth, Japanese culture has fascinated me. Such a wealth of Knowledge and precision in application, working along with the forces of Nature. Thankyou for your videos.

Never seen a site that neat before. You lads have taken a lot of pride in this and I'm here for it

Its So satisfying to see the japanese construction culture

Japanese house construction is really an art.

Wow, amazing detail and craftsmanship for house framing.

In Tokyo I usually see a ~1-inch thick wide rubber gasket placed onto the ribs of the concrete foundation (instead of elm/keyaki pieces used in this video), and then the wood is bolted on top of that. As far as I understand, this is to allow the house to move/flex in an earthquake by relieving stress. It also forms a kind of seal to keep water out of the contact (although the underside of the house itself is ventilated with ports in the concrete foundation in order to prevent mold).

OMG, hands down! This is such beautiful workmanship and technique. Super Cool! I've just finished building my first house in New Mexico. I designed and drafted the floor plan myself (it's not a Japanese style though, a simple minimalistic house), but during the building stage, I had to compromise on every single detail because my builder and contractors didn't closely follow the design, leading to all the details becoming so messy. As a Japanese, I was really disappointed by the lack of workmanship. But, I've learned the hard way. Watching your video has been incredibly thrilling for me. I'm planning to build an outdoor sauna using Japanese construction methods myself. Thank you for this video; I'm definitely going to watch more.

Such beautiful attention to detail and precision. It's just an absolute pleasure to see such craftsmanship!

Ah, the life of a craftsman. I wouldn't change it for the world. Excellent video. Thank you so much for making the time to share these skills. I envy you a bit sometimes. I would love to work in Japan.

After watching a few of these videos I definitely want a Japanese carpenter to build my house no matter where it is. Attention to detail and craftsmanship is top shelf.

Very impressive the time and detail put into it! Keep up the great work!

I don't usually leave comments, but I just had to say thanks. I really love this type of video, it's really relaxing and instructing as well, the way you break down each step is really nice. Keep up the good work ! :)

everything looks extremely clean

Truly a perfectionist's paradise.

Lived in Japan for 7 years I always watched them build it’s fascinating!

Subscribed.Great introduction! Love this かっこいい外人の職人さん！❤

impressive, I love this kind of thing, and really love the attention to detail and how much work and effort is put into this level of construction. I am absolutely in love with Japanese wood working and the quality of workmanship that goes into all the fine details. Wooden structures built completely without metal nails standing for thousands of years.

The building precision is insane!

Very interesting. Clean simple and well explained. Thank you

This is so pure and so amazing.

Listen to how quiet and soothing this construction site is!

My OCD loves it, all so neat, accurate, clean ….. beautiful 😍

NICE, clean work, perfection, lots of pride.

This makes me want to design a new type of foundation for an adaptation to new American style materials. SO much craftsmanship in this.

Such interesting methods. Love learning new ways of constructing things.

大工仕事より基礎に目が行ってしまう、今まで見たことが無い正確できれいな基礎です

what pride in the craftsmanship

It's not construction mate. It's ART!! :) Just found Your chanel, so i've got a lot to watch

Impressive workmanship.

Incredible that houses are built with such precision.

Very intwresting construction method. I hope to follow the entire build. Learning how the construction methods developed the way they are is fascinating.

than you for sharing. I ve watched multiple times and enjoy every time. I want to come work for you

The concrete has an impressive finish. so smooth!

Love this type of construction and level of craftsmanship. I wish I could be working in construction in Japan some day. Thanks for your detailed explanation.

Dude smacking the chestnut shims with the ridiculous cooling fan vest has probably made coat hangars nicer than anything I have or will make

Very impressive to see the techniques from different building styles.

How could you not feel good living in a home with so much perfection and attention to detail...I guess thats where it starts as a culture, perfect harmony from workers, no bitching about salary, stupid jokes about beers after work..just a meticulous pride from the cleanest job site I've ever seen to joinery that's an art form....no wonder the Japanese are such perfectionists.

This video highlights my inferior house build. Fascinating to watch.

Thank you. Although I'm from Europe and usually I design stone homes, sometimes comes a house made from wood. It's totally different to what I see here and it's very interesting.

This is an amazing technique with such respect for precision. I love it.

Absolutely amazing craftsmanship! The joinery is amazing and strong! Such an amazing concrete pour. Corners are so clean as is every square inch of the pour. The craftsmanship is jaw dropping. Thank you for sharing. From the province of Saskatchewan in Canada…have an awesome day🙂.

Very cool to see this in contrast to what we do in the US, thanks for the effort.

The thing I find most intriguing is the fact that in Japan they still cut allot "natural" wood connections. You had to layout all the beams and actually mark and cutout all those connections to fit. In Europe or America they would use metal bracing that gets nailed/screwed into the beams, which is allot faster with less labour.

I should see that video before I build my house. Incredible .

the cleanliness and the amount of air left under the house is astonishing to me as a wisconsinite. We have basements, and i often imagine building my house on a concrete slab (it is SO much more doable in any city here) but it was how he connected the bases, as that’s just pure genius.

Japanese discipline at its best !!!

what a wonderful world of possibilities presents itself when you construct with millimeters instead of inches.

It's absolutely nuts how much attention to detail the Japanese people put into things. In the UK they seem to build things with a "it's good enough, it's not my house" attitude.

Fantastic that you are doing this work as a daiku, you must be learning so much from your master, compared to western methods, the Japanese are miles ahead irt building with timber. Respect the tree, it gave its life for your craft.

I can't thank you enough for the info of your videos. I have been eager to learn japanese carpentry and this is just amazing

I mean, their houses have to match earthquake-resistance levels basically unheard of in the rest of the world, and Japan has many densely populated areas packed w/ buildings quite close to each other. The safety standards have to be incredibly high so buildings won't collapse and fall, destroying themselves and surroundings. So yes, it makes sense they would become incredibly skilled in engineering. The cleanliness has probably a lot to do with their culture of "trying to not be a bother/not get in other's people's way". It's not rare to see people/companies bringing small gifts to the neighbours to apologize for any inconvenience in advance (simple consumable things, like cookies, a scented candle, fruits...) when they are moving, building... Etc.

this was so insightful! Loved it!!

Wow!!! The precision!

Absolutely astounding. Been doing foundations for years.... What you are putting in the mudsill would be fine finish carpentry anywhere in America.

I used similar construction technique when I built my 8x12 shed on six individual foundation piles. I cast threaded rod in concrete poured into the CMUs, held in place and vertical using styrofoam spacers, though scrap wood could have also worked. For termite-deterrence I capped the footers with sheet aluminum flashing, and spaced the girt and beams off of the concrete/cap using stacked stainless steel washers.

I don't know what this is called in English, but in Japanese, it's called 'beta kiso' It means Raft Foundation. "beta kiso" is a foundation where the entire surface under a building or facility machine is a flat concrete slab reinforced with steel plates. Compared to a strip foundation, the foundation's bottom area is larger, which helps to distribute the load, transmit it to the ground or slab, and increase durability and earthquake resistance against uneven sinking. However, it also incurs additional costs. It is mainly used for heavy buildings or when the ground bearing capacity is low, and piles can be added as necessary. Since the entire floor surface is made of reinforced concrete, it also serves as a moisture-proof measure. Traditionally, it has been used for prefab houses and two-by-four houses, but since the late 1990s, it has also been used for wooden post-and-beam construction due to the moisture-proof advantages." There is a comment that says wood and concrete may deteriorate over time, but to prevent this, painting is applied to the foundation and wood is treated with chemicals.

I live in NYC so this video is helping me get my mind off all the atrocious new condos being built everywhere

This is beautiful craftsmanship, and interesting to understand the practical experience that led to this kind of design. Also, your filmmaking and explanations are great, it makes it so clear as to what is going on!

Japanese concrete work... me drooling. Amazing. Then the woodwork comes... me drooling again. Never change, Japan! Never change!

Yet another thing done with impressive Japanese quality. It was very interesting to spend 3 weeks with my Japanese friends. Even the cast iron manhole covers had different scenes that varied from city to city. This house build is typical quality construction done with care & not banged out US style. The opposite occurred in SE Asia where house construction left a lot to be desired but done cheaply...

Holding my breath now to see those vertical pillars go in - I was spellbound - and it was a wrench to come back to the real (untidy) world when the video ended.

Very interesting and informative video, explained it clearly and simply. Thank you so much for sharing with us.

Great video. Make sure we find you when we move to Yokohama from Oregon!

see that is what i call a good old woodworking, so nice to see, looks really really really awsome and beauty, cant wait for next vid :D

Mindblowing! That's next-level carpentry. Looking at the architecture of the houses around the construction site, it's almost a shame that same attention to detail is not given to the plain walls and windows.
