This is one of my favourite long running projects on youtube. It's always a pleasure seeing this channel pop in my feed.
Happy to hear it - and it's definitely a long running project!
Absolutely, I agree.
I have the same reaction.
🙂🐿❤️🌈
I've been watching him from the start and have loved it. It'll be a bittersweet day when he decides his home is finished.
I love this content too. Do you have recommendations on any other content like this? It doesn't have to be japanese related.
@@emanon9642 It really depends on your likes. I'm into crafts and woodworking so my favourite long running project channel is "Advoko Makes". He does stuff that I won't ever attempt but it's quite interesting. Sometimes videos take quite a while though.
that thermal camera was your smartest move, bro.
Yes, need to do another video with it.
I can’t imagine the sense of accomplishment you will have when this is all done. Best of luck!
Thanks very much! Looking forward to the day when I can say “finished”.
@@bobrobrudolf1243 thanks you! How do you you keep your house warm?
@@TokyoLlama If I learned something living in a house built by my grandfather in the 70s. With a house you are never "finished" ;)
It's never going to be "done". It's a hobby now isn't it.
@@Rockmaster867 with old houses, when you think you are done, you suddenly decide to redo something you did in the past. The never ending project
One really does get a sense in these videos that you put the same meticulousness into what work goes on behind the camera, as with in front of it. Superb editing, videography and narration.
Thank you very much! I do enjoy the process of both the house and making the videos.
Yes, but why that ghastly loud music in parts?🙃
@@wewerecamerashy5190 In my humble opinion, when you are not talking, no music would be better and, when not talking Traditional Japanese music would be sp appropriate and you should have access to recordings and advice in what genres would be effective and affordable, maybe free.
DUDE.
Just shy of 500 bucks for proper insulation? That's a steal, mate.
Really good work, by the way; I've insulated a couple attics, and you did that really well; a pro would probably charge well over a thousand (USD) for that job, and you nailed it for half to a quarter of the price!
Keep it up!
Looks great!
My only concern is the pot lights. Here in the US you'd probably have a code requiring a cover (hat, if you will) to protect the insulation from directly touching it & causing a fire.
This was my immediate concern, as well.
Most likely LED lighting and thus not rally an issue. Old incandescent bulbs and or transformers got much hotter
he even shows on the fixture that it says not to cover it. And with google translate it seems to say do not cover with wood as there is a risk of fire. Not sure why he highlights this label if he goes on to cover the fixture anyway.
Yes, I'd think you would just build a simple box over it so it's not in direct contact with insulation.
I'm about to start the insulation process on my 150 year old minka in Nagano. This past summer I re-insulated the kitchen using rock wool .... after removing a foot and a half of straw, dirt, and dust, which was i guess the insulation of the day. Great timing for this video! Cheers!
Nice! What are you planning to do with your roof? I'm thinking rock wool or the Earth Wool, perhaps Neoma foam, keep changing my mind!
@@TokyoLlama I'll do the inside cielings with rock wool and make that as tight as possible for now ( baby steps to retain heat). in time maybe put layer on layer. When it comes time to do the inside of the thatched roof, I really don't know. There is a nice part of the old house where I can reclaim a large room with exposed beams... the question is how many beams do I wish to expose vs. how insulated do I want to make it. A friend of mine did a similar reclamation and used beautiful pink fiberglass and finished with gypse. It seems to make sense for the uneven surface ... but seeing you work with the neoma foam looks so satisfying! I'm just getting started and loving it. I can't wait to hear about your windows, double pane glass sounds like a dream!
@@EricJMcA sounds great. Same here with the exposed beams but I’m going with beauty over practicality, so we’ll expose the all of the beams in the attic. In regards to the windows I found that the custom wooden windows are not much more expensive than custom sized hybrid ones. If off-the-shelf sized windows fit your openings that’s the cheapest way though.
I live in Austria and Minka here is the name people give to a cow or cat. 😅
What a wonderful struck of luck to have found a house from the 80s built in the traditional style.
You own a jewel of a house and are preserving it beautifully while bringing it into the XXI century.
Man how do you even have the energy? Making videos is hard. Home Reno is so hard. Both? And kids? Be my mentor
You'll be a master carpenter by the time you finish the house. This is the neatest insulation job I have ever seen. Looks fantastic.
Thank you!
One of the silver linings (excuse the pun) is that you will have a very complete record of everything you have done including materials used, difficulties and solutions. Invaluable for future projects, maintenance and repairs. For us it is invaluable as your mistakes don't become our mistakes. Thanks.
No worries! That’s very true as I’ve referred back to my videos a few times to check to see how something was done when planning a new project.
My house in Ibaraki was 8 years old when I bought it last year, a newish home by Japanese standards. Still cold in the winter and supposedly has more than average insulation, but under the house is very sparse. Once I heat it its fine, but those early mornings are chilly. We have double pane windows and the engawa heats up nicely on those bright winter days. It certainly is something to consider here in Japan when buying a home, but as with everything there are work arounds and solutions.
I'll have to upgrade the underfloor insulation at some point unfortunately. Wish I knew more when the carpenters were working on the floor as I would have been more demanding, and saved a whole lot of work down the track.
The house really has come a long way since you started years back. Even as a viewer I feel a sense of pride in where it is at today. Great work!
Nice to get an update of the house! If you plan on using more of the blue foamboards in the future, maybe you should look into an electric hot knife or hot wire cutter. Looks like it was a struggle to cut through. Thats what we used to make architecture models with in university (don't know if it is common to use in building constructions). Anyway, just a tip:) and don't forget a respirator-mask or something. Those fumes are not pleasant!
Thanks very much - yes, it was a bit of a struggle cutting through the foam, will check out the tools you mentioned!
@@TokyoLlama jigsaw is also a good contender to it. And something you can also use on many other projects.
@@heuhen I’ve got a jigsaw, the problem was finding a 75mm blade!
@@TokyoLlama I see that
@@TokyoLlama Take and check "bayonet saw" the question will be then, do you need it for just some insulation work.
I know nothing about renovating houses, but I love watching your videos.
Thanks very much!
Man that amount of work makes me just wanna spray-foam the whole thing haha
It would be easier...
Haven't looked at you in a while, finally something good to start the day. For 200k subscribers you make videos like a high end channel. Probs!
Thanks a lot - appreciate it!
Really my favorite channel on CZcams . Thank you and have a smooth " ending" on the project.
I always love to watch other people renovating houses, since I have done that in Norway. And since I have done renovating house before, there is always times where I go: "oh, I wouldn't do that!"
It is also very fun to watch how different people around the world do things. For example cables in the walls, In USA they just put normal cable inside with the isolation. While in Norway we put an vapor barrier between the isolation and the inner room, and build a little out for air flow and cable management, where we put cables inside flexible-pipes, to prevent fire/damage/electrocution/ and ease of maintenance (replacing cables).
If it was in Norway, with our high difference between inside and outside temperature, we would for example on the ceiling put down a vapor barrier and then isolation (not those in bags).
When the electrician came in to replace the lights I asked him about keeping the wires outside the insulation and he said it was okay, but it was something I wondered about. In terms of vapour barriers seems the Japanese generally feel the bags are sufficient!
This is the home renovation project that I've been following since the beginning and I love seeing everything you've accomplished. Congratulations and a giant hug from the other end of the world Chile.
Thanks very much for watching for so long!
Is always nice to see your updates! We're all rooting for you. Cheers from Brazil!
Thanks, appreciate the support!
Awesome work insulating, it's so interesting about the things to think about when insulating a traditional Japanese home like yours, really cool. Love your videos and seeing the progress! Your boys should be nice and warm in their room for winter!
That is a lot of work. But it will be worthwhile in the end.
I hope so! Got to be done.
With the added insulation, assuming you utilize a vapour barrier system, you will have changed the dynamics of the sit flow throughout your attic. One way to increase the flow of air at a small cost is to utilize “Roof Turbine Vents” which will pull a lot of air through your space, which will keep the areas moisture free. Just a though. Love your home and what you’ve accomplished. Excited for more content.
Thanks, yes, I’m thinking of something like that, particularly once we insulate the roof.
Ive been following along since the very first video and these are by far the most inspiring, wholesome, beautiful, and soul satisfying videos to watch. Such a treat whenever a new update comes along
Thank you!
Instead of just insulating, using some air gap sealing tape would be hugely effective. Any air gaps even in the ceiling will lead to a lot of heat loss that can't be mitigated with fibreglass insulation
I’ve been waiting for this kind of content from you! My own house project wrapped up over a year ago now, and I kind of miss the whole process. Looking forward to seeing the rest!. (Oh, and I appreciated that snowy shot too. We don’t get much of it down here in Mie.) 🍻
Thanks Jordan, jealous you’ve finished already. Haven’t had any snow so far this winter but saw some on the forecast for next week.
Better not to finish too fast or you might run out of content!
@@shiromochi-kun Haha I was thinking the same thing. (That’s my experience. 😆)
@@shiromochi-kun I don’t think I’m in danger of finishing too fast!
@@Jordan-inJapan My experience with old houses, when you are finish renovating it, is that you suddenly decide to redo something you did in the past
After seeing how your house develop from the first video (i found you somewhere on 3rd one) Im so impressed on your progress :D.
So happy that it's going well without much trouble. Can't wait for next vid.
Thanks a lot of for watching for so long! Still a long way to go - will try to get the next vid up sooner rather than later.
Is it wise to put insulation directly on the downlights? A short can cause a fire. I suppose they are LED so there is very little heat but I would still put a metal cup or something on top of the connections.
These lights are rated for insulation to be placed directly over (probably should have showed it in more detail), whereas the old ones I replaced weren't.
YAY! You're back!
Thanks, that's good to know it's probably going to be worth it!
Sir I believe your slowly turning into Bob the Builder, the hard hat just solidified my belief. 😅🤣
No but really I love watching your videos and I always get excited when one of your videos pops up on my feed.
Good luck on your future projects in your lovely home. Cheers from Houston,Texas, USA!!
Living in a place where we have cold winters, it's very satisfying to see lots of insulation being installed. I bet your house will be a lot more cosy next winter!!
I think you are the first renovator I've seen for homes in Japan that takes thermal bridging seriously. I'm looking at vapor permeable 透湿シート housewrap for a job myself to get the wind barrier without trapping moisture anywhere.
Insulation....the bane of my house. Kudos to you for getting it done and also giving an accurate account in USD, instead of the lazy man's "100 yen is $1" nonsense. 😂
I look forward over time to the heating/cooling efficiency comparison that I just know you already have a plan to do in each season!!!!
Yes, I put smart thermostats on the outside and inside of house last year, recording the temperatures so can do a comparison over time!
Babe wake up new Tokyo Llama video
As an architect, who has a particular interest in Japan, it's culture and traditional architecture, I'm envious. As I practice Japanese carpentry in my spare time, the thought of being able to find and move into and renovate an a old abandoned house would be my dream.
8 million Akiya houses available in rural Japan in 2023.
There will be more and more available, just hope that not too many get knocked down.
I’m enjoying the videos very much. When i lived in Japan in the 1980s it seemed such a shame so many beautiful places were being torn down so great to see its turning around. My question is why are you insulating both the ceiling of your boys room as well as the roof? when I renovate here in Canada, a knee wall area would be either/or. You want a continuous insulated envelope but in a cold place you don’t want to trap the air outside the sealed envelope (say in a knee wall area in a sloped roof) because you will get mold. Some heat will always escape from the boy’s ceiling into that space and it is moist.
I'm so used to seeing XPS board used as a crafting material for miniature landscape etc that I was genuinely startled to see it used for insulation, which made me laugh. I guess it shows what kind of stuff I watch/do on a regular basis.
very clever solutions. i like how you use you shop vac to clean the floors and wall cavities after cutting and before installing the insulation panels. a contractor would not be so tidy. its a good job. this is a timely project too. it seems we may have some -6 degree days next week. be warm!
Thanks. I got that from watching the Japanese carpenters, always vacuuming as they went along. Yes, looking a bit chilly in a few days!
Well the only thing I would have done there as extra would have build some walkways over the insulation. Its just if you ever need to go to the space with the insulation to do or check something. It makes so much easier to have at least a narrow walkway that you can use without worrying about the insulation itself or where you can step. Like if he ever needed to run some new wires or something for lamps and such would make that way easier.
Another great video Jaya. It is a balancing act in these old houses when it comes to insulation. The house needs to breathe and it is also needs to retain heat. There is no perfect solution it is what it is with these kominkas.
Thanks mate, notice the cameo of your house in the video?
Yeah the old girl still looks the same 😂
Houses don't need to breathe, you just need to control where moisture goes.
@@rsmith02 These houses do.
I definitely feel your pain. My wife and I currently live in Kyoto prefecture and received a lot of snow this winter. Our house has a traditional house with no insulation or double glazed windows. The wind pours through and we cannot retain heat. My wife and I actually have chosen to move into my company provided apartment just to stay warm also, to save on the electric bill, which last month was more than I have ever spent in my life on electricity.
I discovered your channel only a couple a weeks ago, and I've binged all the videos. They're amazing! Keep up the good work - love from Norway
Great, thanks for watching!
Thank you for the R value conversion. I wondered how the R value for insulation here could be so low. Now I get it. Appreciated.
Jays, You know a video has good content when you watch it several times☝️All your videos seem to be meticulously researched , edited and delivered to a high standard. Did you get much video of the ceilings being fitted and lowered? Can’t remember a video of it. There must be loads of work in Japan just dropping ceilings in these old properties. Look forward to the window video. 👏
Thanks Stephen, I didn't get much footage of them doing the ceiling as at that time I was only coming to the site once a day or so, so missed a lot of stuff. Wish I had more to refer to as I'm going to do a dropped ceiling on the main roof.
You have really invested so much in that house. I like to follow your house project, it's really enjoyable. Thanks
I hope you were rewarded for all your hard work. Next up: the blue tarp. 😂
Blue tarp is already gone! But fixing that roof is next on my list.
Yay!!!! thank you for posting 🙏
So excited to see the video
I'm very excited whenever you upload a new video. I love seeing renovation work like this.
Awesome! Thanks very much.
Cant wait to see you get it all done!!!
You're doing an excellent job! You'll end up with 200mm mineral wool laid over the ceilings wich is a huge improvement, check if you're happy with your heat losses after this. Here in the UK 270mm mineral wool is pretty standard to achieve the minimum U values required by building regs for new houses (0.16). It's quite a high standard to be fair but if you want to go above and beyond maybe in the future you can install a 3rd 100mm layer and bump it up to 300mm insulation! Best of luck, can't wait for the next video!
Thanks, I'll see how it goes but hoping since it's going to be an internal ceiling space once the roof is done it will be sufficient.
Rock wool is also good for sound deadening which is a bonus!
Yay! , a new Llama video.
This is so good
That's probably the best insulation job I have ever seen done, Good job planning doing this during winter, When I did this in my attic as a kid it was summer (not smart).
I did most of the work just as winter was starting. Definitely couldn't do it during the summer!
Wow! Nice work.
I've been following you for years, since you bought the house. In all of your projects, you not only put in a great deal of effort, but also a great deal of thought and consideration. I eagerly await new videos.
oh man im so glad youre still going with your renovation and that its going well. my wife and i actually got ours finished in kyoto. im not trying to show off because thats not my nature i just happened to run into your video after a year since i saw the last one and got reminded of our journey. we were lucky to find one that was smaller than your home and most of the frame wasnt as screwed up from neglect so it meant less work. fortunately her parents have enough money to help us which in turn sped things up and turns out we both like living out there. unfortunately we are still tied up wo the city since i "teach" and she works from home so we live half in the city and half in the country side. eventually we will completely move there when we start a family and more savings but for now we enjoy it half the year
I ha d NO IDEA there was a small "crawl space" between the 1st floor and the attic.... I never really understood how you were able to have that small office space, and just assumed it was because there was a lower ceiling in one of the areas.... but I didn't put to much thought into it all until now..... I think it's a GREAT SPACE to have just for storage!!! BUT you would need to put down some plywood before storing anything of weight in there...
- - The old style of houses NEVER CEASE TO AMAZE ME!!!! And it seems like I'm constantly discovering something new about them LOL
THANK YOU FOR YOUR CHANNEL!! I have learned SO MUCH about my FAVORITE style of houses!!!! :D
Yes, i probably should have done a 3d drawing of how the house is laid out as it’s quite complicated - maybe in part 2. On the other side of the office I’m thinking of making some storage space like you’ve suggested.
Awesome video
So satisfying to watch! 👏🏻 👏🏻
amazing work........
Finally back! I was waiting for this video
He's back!!! 😁
This house is just a beauty
Great Job
Wonderful video! Thanks for sharing it. ✌️
Thank you for your excellent video.
I love your channel! Great to have new episodes when they're ready! :)
I love your home renovation videos! Keep them coming
I thought I saw you around Tokyo. I am glad to see the continuation of the series. I would really love to watch your video on windows.
Looking forward to that.
We might consider buying an old house and renovating like yourself.
thank you for this video! always enjoy watching your work
Always a good day when you put up a video
That is such a beautiful house!
Love checking in every so often.
I am always happy to see another video. Thank you for sharing
Im happy that Tokyo llama is back 🙂👍
Fantastic music choice!!
From zero to hero in no flat timeee
These are such beautiful houses... I am in awe here...
Good jobu! :)
The house wrap was a smart move. The key to insulating this place is to create a vapor barrier between the old wood/structure and your living spaces. Should you seal everything up, you would just create a new problem. This seems like a very smart insulation strategy.
Not sure why you'd want a vapor barrier vs an air barrier. Keep the conditioned air in the conditioned space but let any errant moisture find its way out. Look up smart membranes, vapor permeable housewrap, etc.
AMAZING 🙌🙌🙌🙌🙌🙌🙌🙌🙌🙌
Wow! Over 3 years of being your virtual neighbor.
I love seeing how far your home has come. It's really inspiring.
Thank your for your time and effort to make the videos. They are pure joy to us at home. I
Great to see a new video mate. I cant imagine how cold it must be in those old houses.
Thank you for the update. You’ve explained many of the puzzling questions I have had about Japanese domestic architecture.
such a mammoth job you have undertaken, mate! Doing us Aussies proud over there, keep striving your are an inspiration!
Always the most enjoyable. You established the benchmark.
🙂
ALWAYS good to see you!!!!!
Thank you!
As always, nicely done. I have a mental picture of a smiling wife noticing a warmer, less drafty home. Must admit the earth wool is something I never heard of, interesting.
Loved the video!
Glad to hear it!
Thank you for the upload. Great work!
Thanks!
Well another fantastic video and cant wait for more in the future!
Thanks very much!
Always beautiful job, watching your videos makes you feel that anything is possible with a little hard work!
Your approach to keeping the ventilation is spot on. Nice work and I enjoy the videos.
Ahh yes I always look forward to these updates. Keep them coming :)
Thanks! Will do!
Love the updates ..keep up the great work you are doing.
Thank you!
Watching you lay out that insulation on the ceiling was extremely satisfying
