Yes

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

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 KZfaq

"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.

In North American, we welcome with f word before even work starts 😅

Glad you like it! The Nuki information was difficult to explain, but I hope the animation simplified the explanation. Thank you for watching!

Have fun!

"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.

leap away, clueless troll

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?🤣🤣

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.

This is a traditional build and the majority of Japanese housing is prefabricated unfortunately. Yes, it’s beautiful. Thank you for watching!

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'.

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?

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

Hi, thank you for watching. So the tool you are referencing can be found explained in another video. Check out this video: kzfaq.info/get/bejne/pZmAm6tqu6zRioU.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.

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.

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.

Yes, it is a specialized tool with a plumb bob inside.

Most common brands for Hozo Kiri are Ryobi, Makita, and Hitachi.

I typically see 3 different brands: Ryobi, Makita, and Hitachi.

Unfortunately no...

These shoes are called tabi(足袋)

I hear you. You would need to get a working visa otherwise we can’t provide you with one.
