I can't help but feel that recently this channel quality has gone down. Don't get me wrong, the production is great, but similar to the other recent Japanese episode, these videos feel slow, stretched on. Like you keep hearing the same facts repeated over and over again over with the same graphic showed over and over again. Basically very little interesting information given the duration of the video.

[@zwesithu901]

the first picture of pagoda is not from India .

[@yellads]

Should rename the Tower to "The Tower That Tempts Fate" T4F lol

[@kalfunai]

what is this thing bhagoda?

[@MartensFamilyHomeMovies]

First you write "Why?" and write なぜ, which is pronounced Na-Ze, next you write "How?" and then write 何故　which is pronounced Na-Ze, (because you wrote the same exact word, it does mean why) 'How' is usually written as 'Doh' or 'Doh yatte' (You're welcome)

[@Zezetheb]

I don’t know why I’ve never considered how those ancient pagodas have withstood earthquakes after all this time. Such a fascinating design and super cool to see that homage in the sky tree!

[@rych7852]

Sadly a lot of them were destroyed during WW2, not natural disasters. If you go to the Sensoji Temple (not too far from Skytree) Its basically a replica nowadays

[@cashewnuttel9054]

Do you think the Chinese will be super upset with this video?

@@cashewnuttel9054 If this makes them angry, I think Chinese people are pretty short-tempered.

The duty to maintenance and general taking care as a society through the ages is also a key part of the longevity. It's also why old stuff of the modern era doesn't look as old as it would in other countries - it's about the people as much as the structure itself.

[@johns7539]

@@rych7852it’s said that no Japanese pagodas have fallen down in a earthquake. Off course some fave burnt down afterwards, you know candles, all wooden structures, a little shaking

[@danirey425]

The sliding joints of the temple was pretty impressive, Japan has really been ahead of the pack in earthquake resistance

On my opinion this is the most intersting and also the most beautiful TV tower in the world both in terms of construction and appearance. What the Japanese have built here is amazing. LOVE THIS 😁😁

Yeeah. The skytree is so nostalgic for me 🥺transferring alone for the first time from narita to haneda and seeing the tokyo skytree as a landmark

[@TheB1M]

Thanks for watching our last video of 2024! Remember that the Tokyo Skytree is a "tower" and not a "building" or a "skyscraper" so it isn't included in the ranking of the world's tallest buildings. Details on what qualifies here 👉 www.theb1m.com/article/what-makes-a-building-a-skyscraper-2020

I saw the Skytree in person. The 'lattice' of steel tubes is super impressive. Looks way bigger in real life than on video. How the tubes fit together, the amount of welding, truly awesome.

[@calvinl2149]

Definitely agree that the Sky Tree looks bigger and stronger in real life than on video. I grew up in Toronto so saw the CN tower all the time but it looks so slim compared to the Sky Tree which has so much more girth than I think people expect because of its see through outer lattice.

I read about this in grade school and still fascinated by the way the Japanese architecture works

[@clinto72]

I've been up in the sky tree tower and the view is amazing. But what's more amazing is how big Tokyo really is. It's so spread out, with lots of city skyscrapers everywhere. Definitely worth a look if you go there.

[@zam023]

Did you try to look for Tokyo Tower when you were up there? I did but it took some time for me because visibility was bad on that day due to rain >_

[@clinto72]

@@zam023 I saw the Tokyo Tower in person and that was cool but wasn't really looking for it while I was up there as there was just so much to look at.

[@RF-zo3wy]

It's a megalopolis. Tokyo(Metropolitan) is very large. It influences my city, its skyscrapers continue my city, despite that my city takes 40km from Tokyo(station).

[@Stone_624]

Awesome stuff about Japan from you lately. As someone who's been in Japan since 2013 (Lived here since 2016), I love being a part of this city and this culture. The scale at which Japanese do things, and the organization and craftsmanship of their work, is something I've aspired to for over a decade now. It's tough living and working here (For a magnitude of reasons), But it's 1000% worth it in my opinion.

[@alexander3925]

It really is remarkable how such a tall structure can stand in one of the most vulnerable earthquake zones in the world, while still having this aesthetically pleasing design! Great video with really good explanations how this is possible!

[@DieFlabbergast]

It hasn't had to stand up to a strong earthquake yet. The 2011 Tohoku Earthquake (the one that generated the disastrous tsunami) hit when the tower was mostly finished, but that quake's epicentre was a 373 kilometres away from Tokyo. Nonetheless, even if a major earthquake occurs near or underneath Tokyo, I think we can be confident that the tower will be able to take it. Japanese engineers are REALLY good, and they know everything about earthquakes and earthquake-resistant designs: they have to.

[@yamasho9154]

Being functional is beautiful.

[@earlysda]

But it isn't earthquake proof. Nothing on this planet is.

Thanks so much 🙌

[@xrq3223]

Definitely one of the best videos of the year

[@danmcleod17]

I got to go up both the Skytree and Taipei 101 this year, both phenomenal feats of engineering. The view of Tokyo from Skytree is amazing and you get to somewhat grasp the true size of the city. On a side note, the soft serve ice cream there is delicious!

[@sirromja]

There's also a bang-up katsu restaurant nearby. I stuffed myself silly after going up the Skytree.

[@honolulutei1753]

Amazing access and footage of the parts we don't normally see! Thank you for the behind the scenes look, it's a truly beautiful structure in person.

[@Justyburger]

I was up there about 8 years ago. Amazing place. Tokyo and Japan in general is a great place to visit.

[@commando_spz5943]

When I was living in Japan, I spoke to a guy who was working on one of the top floors of a skyscraper during the 2011 earthquake. He said that all the skyscrapers flexed to such an extent that you could "see around" the surrounding buildings as they swayed, and see other buildings you normally wouldn't be able to see.

[@marion817]

I’ve been up the Skytree - twice! - and it’s amazing to understand now how it’s such a marvel of engineering and structural design. Wow!

[@Train_Shrine_in_Japan]

In Mar 2011, M9.1 earthquake hit Tokyo SkyTree. The tower was still under construction, but the height was already reached 620m. After the earthquake, a chief engineer said "It is no issue and no damages, the team continues to build on schedule".

[@Nunelii]

The Tohoku earthquake didn’t actually hit Tokyo at 9.1. 9.1 was the magnitude recorded at the epicenter (which was located 30km deep, 100km off the Sendai coast). By the time the quake reached Tokyo, its magnitude had already decreased a lot, even though it was still strong. Even Sendai wasn’t hit at 9.1 magnitude. Trust me if tomorrow a 9.1 magnitude earthquake hit Tokyo, there wouldn’t be a lot of buildings still standing. Just a reminder that a 9.0 earthquake is 10x stronger than a 8.0 earthquake, which is already 10x stronger than a 7.0 earthquake (which is the average magnitude of the strongest earthquakes on the planet).

[@HATA0_]

If my memory serves me right, magnitude represents the energy released by the earthquake itself. In Japan, the intensity of the shaking is expressed using a scale defined by the Japan Meteorological Agency (JMA). During the Great East Japan Earthquake, Tokyo experienced shaking levels of 5- to 5+ on this scale (enough to cause furniture to rattle and items to fall from shelves). If Tokyo had experienced shaking as strong as at the epicenter, the damage to buildings would likely have been much more severe.

[@TheFergyme]

There was a documentary recently about the actual building of SkyTree on NHK and the program Project X. It was in Japanese but is hugely impressive, especially about the actual builders and their roles. We live about 30 kilometers away but can see it from our living room window and behind it, of course, is Mt. Fuji, which we can see when the sky is clear.

[@fionngodwin9625]

The production quality on these videos are insane

[@aoki_ch]

I visited the Skytree tower about 6 years ago. It was amazing.

[@kusemunn]

Can you make an video about maintaining these systems? I mean anything with a bushing or a damper wears out sometime.

[@StevenBara]

Given it's height of 634m it can be seen for up to ~90km. This covers all of the greater Tokyo plain. It can be seen up to the most eastern point in Chiba, Chochi and also it's most southern point Minamiboso. And that's just from sea level. (Given a plain line of sight of course) As Japan is rather elevated in many areas, you are able to see it from many mountains surrounding Tokyo, especially in winter when the air is much more clear. And even more so at night with it's bright light on top. Yet every time I'm going hiking here, I'm reminded that I just ascended 1000m+, much more than this enormous tower.

When it opened one could walk down exterior staircases from the top; crazy! Even the highways are designed to “yield”; they have massive steel ropes from the highway deck to the support pillars. Thanks!

Is it possible to explain how such huge tuned mass dampers were hoisted to their lofty heights? What an incredible structure. Happy New Year from Christchurch New Zealand.

[@EduardoEscarez]

Is just assembled on site, because most of it is only weights. There's one in Santiago de Chile that looks like Taipei 101's one, and is just a series of discs joint together and hang out with steel cables. That's the true beauty of the system, is simple and runs mostly on physics. Happy New Year from Valparaíso, Chile, on the other side of the Ocean.

There actually is a balcony at the top of the tip of the Sky Tree. You probably saw that video on your way to the observation deck. I wish the tip was open for public for a higher entrance fee like $200 or so. That would limit the number of visitors, while still giving enthusiasts like us the chance to experience the amazing view.
