This article would be much more interesting for my Kinder class. This article would be awesome for an ocean unit and tying it in to literature about the Kraken and sea monsters. This information is actually very exciting and interesting because of the ideas that I have about an inquiry unit and bringing in Guided Language Acquisition Design Strategies. Using a pictorial input chart and chants about zoologists. So much learning can go on.
Renowned zoologist and team shed new light on seldom-seen creature

In ancient legend they were called the kraken, fearsome sea monsters of giant proportions that would drag sailors down to their doom.
More than 2,000 years later, the world still remains mystified by the creatures we now know as giant squids.
But researchers, led by internationally renowned zoologist Tsunemi Kubodera, are doing their best to unlock the secrets of the fabled deep-sea denizens.
Last week at the National Museum of Nature and Science in Tsukuba, Ibaraki Prefecture, Kubodera conducted a dissection of a 394-cm-long specimen along with a team of researchers from universities and other institutions around the country.
“The giant squid is a very rare animal,” said Kubodera, who in 2012 became the first person in the world to film one of the giant creatures in its natural habitat, descending nearly 1 km beneath the surface in a small submersible to record the creature near the Ogasawara Islands about 1,000 kilometers south of Tokyo.
“We have learned a lot about the makeup of giant squids’ bodies, but we want to learn more,” he said. “We have researchers here today who want to find out about the squid’s nervous system, its eyes and its blood. I’m a taxonomist, but today we’re looking at the giant squid from a physiological perspective. We’re looking at it from lots of different aspects. Everyone here is interested in giant squids and we want to find out more about them.”
Giant squids are one of the most seldom-seen animals in the world, and much about them remains unknown.
They are believed to be able to grow up to 13 meters long, and can weigh almost a ton. They live at depths of anywhere between 300 and 1,000 meters, and have eight arms and two additional longer feeding tentacles. These are tipped with hundreds of jagged suckers, which they use to snatch prey from up to 10 meters away.
Giant squids have two eyes the size of dinner plates — the largest in the animal kingdom — and a sharp beak similar to a parrot’s. The main part of the body is called the mantle, which houses all the basic organs. On the underside of the body is the funnel, which the animal uses to exhale, expel waste, lay eggs, squirt ink and propel itself through the water.
“One of the things that I like best about them is their size,” said Kubodera, who in 2004 became the first person in the world to photograph a giant squid in its natural habitat, and in 2006 became the first to film one in any environment when he caught one with bait off the Ogasawaras.
“You don’t normally see squids as big as that,” he said. “When you dissect a normal-size squid, the stomach is very small and so are all the other parts. When you dissect a giant squid, you need to use your whole body just to move it. They really make an impression. They have the same bodily makeup as normal squids, but they are much larger. That’s the appeal for me.”

Professor Mitsunaga Narushima, chief of the department of plastic and reconstructive surgery at Mie University, was invited to assemble a team of researchers to take part in the dissection. The 15 team members were drawn from a range of medical fields and assigned different roles according to their area of expertise.
“This was a very valuable opportunity, so I asked a lot of people from different fields of research to come and look at the giant squid from a medical point of view,” Narushima said. “We have people looking at the nervous system, at the eyes and at the blood.
“My field of research is the nervous system. Plastic surgeons do a lot of treatment on peripheral nerves and I am looking at developing a new treatment. I’m trying to create a model based on experiments on live squids. No one really understands the workings of squids, so I have been trying to find out by asking people like Kubodera. He said no one really knows, so he asked if I would like to come along and get involved. I thought it would be interesting to do that from a medical point of view, looking closely at the nervous system.”
The team dissected a squid that had washed up in the Bentenhama area in Itoigawa, Niigata Prefecture, in March 2014. It was frozen the same day and then stored at the museum in Tsukuba. The squid was thawed the day before the dissection.
Kubodera began by laying the squid on the floor of the dissection room, washing it with a hose and then spreading the tentacles out to be measured. The total length of the animal was 394 cm, with a 165-cm-long mantle and tentacles that extended up to 187 cm. It weighed 174 kg.
Kubodera cut open the mantle as the researchers looked on, and removed the internal organs including the stomach, liver, reproductive organs and hearts. Giant squids have two hearts — one brachial and one systemic.
“We found out it was a mature female,” said Kubodera. “It was a female and it had very large ovaries. The fallopian tubes were also very large, and it seemed as if it was in a condition where it would have laid eggs that year. I’ve never seen fallopian tubes as big as that.”
Once the parts of the squid were separated, the researchers took a closer look at the areas that interested them.
“Squids are special,” said Chihena Banda, a postgraduate student in Narushima’s plastic surgery department at Mie University who moved to Japan from his native Zambia in April. “They’ve got giant nerves and it’s a nice way to study how nerves function. You can apply that to human beings as well.
“I knew the professor is into nerve research, but I didn’t think we would be studying it on a squid. But it’s exciting because it’s got special features that no other animal in the world has, and an opportunity like this — to explore this animal, study it and finally get to translate all this hard work into human benefit — is a good opportunity for me.”

The dissection was organized by filmmaker Shinichi Motoki, who is currently making a documentary about Kubodera’s work. Motoki will also film Kubodera hunting giant squids in Toyama Prefecture next January and February, and he aims to complete his documentary by April or May. He intends to market the film to an international audience.
The expedition on which Kubodera filmed a giant squid in the wild for the first time was part of a collaboration between NHK and the Discovery Channel, and produced ground-breaking programs which aired on those channels in 2013. Kubodera’s work has not been broadcast since then, however, and Motoki is keen for the world to take notice.
“Kubodera is interested in squids from a very pure point of view,” he said. “He wants to know all about them. What is a squid? He’s not interested in discovering what medicine can be developed from squids or doing something from a business point of view. He just wants to know how they live, and I think that’s a great thing.
“It’s a very basic form of science. Why is a leaf green? If you know the answer to that, that leads to something further. He’s always searching, always pursuing something.”
Giant squids live in all the world’s oceans, but sightings are most common off the coast of Japan. Motoki explains that trenches in the Sea of Japan act as a trap for the animals and the cold water temperatures in winter force them to the surface, where they are swept toward shore by strong winds.
“Giant squids are one of the rarest animals to see, but you can see them in the seas around Japan,” he said. “You can see them come right into ports, but you only see that in Japan.
“I want to tell the world that the animal that was known in history as the legendary kraken can be seen in Japanese waters. I want people to know about squids and I want people to know about Japan’s seas. That’s why I’m making this documentary. I want to convey the wonders of Japan’s seas, with the giant squid as a symbol.”
Kubodera is now 67 and technically retired, and he has been given the title of curator emeritus at the National Museum of Nature and Science. He has also researched octopuses and normal-size squids over the course of his career, but he acknowledges that it is always the giant variety that appends itself to his name whenever he is mentioned in the media.
As he goes about his business in the dissection room, pointing out details to the researchers and peering with wonder at the creature’s inner workings, it is clear he wouldn’t have it any other way.
“I’m too old for new challenges,” he said. “But there are still things that I’m involved in that I have to make sure I do properly. I’m still involved in surveys in Japan. There are varieties of octopus and squid that still don’t have names. We have to give them scientific names, and that is one job I am involved in.
“Then there is the next generation of children. I want to teach them about the interesting things that live in the sea. So I am still involved in filming underwater in Japan and putting that information out there.”

After the architecture lecture, this was a wonderful read tying in to what I learned about it last Saturday. The issue of Japan being a scrap and build society versus lasting architecture and renovation is an interesting topic to bring up. A question to pose to students when tasked with an architectural project is what materials would be best to use, that will deteriorate least/ weather gracefully? How will your building maintain itself or generate funds to be able to maintain itself, future reparations? Where would you build? What would you use it for? Who is your intended audience/ consumer? How important is nostalgia/history when deciding to redevelop?

The future of Tokyo’s Nakagin Capsule Tower hangs in the balance as architectural enthusiasts attempt to preserve the fading landmark
CHRIS RUSSELL
Staff writer
In the 1970s, if you were to take a walk through a certain part of Tokyo’s upscale Ginza district, one building in particular would have almost certainly caught your eye. Eschewing anything resembling traditional design, the zig-zagging geometry of its array of small, gleaming pods cutting against the azure sky, the Nakagin Capsule Tower was, and remains, a striking sight.
While the building exuded a technology-fueled optimism at the time of its construction in 1972, the structure, designed by renowned architect Kisho Kurokawa (1934-2007), gives off a different impression today, with the building seemingly hemmed in by the towering glass-and-steel structures that now surround it and a large net almost forlornly cast over the building ever since one of its windows fell onto the street below — not so much a future that awaits but a future lost.
Unsurprisingly, its unique, forward-looking design has seen the building become a minor pop cultural fixture, featuring in numerous music videos as well as films such as “The Wolverine” starring Hugh Jackman — in the latter case as a love hotel in Hiroshima Prefecture, naturally.
Although the Nakagin Capsule Tower is still capable of lending such productions a futuristic sheen, its reality is one of neglect and decay. The threat of demolition has long hung over the building even as a committed group of residents and architectural enthusiasts have fought to save it, with their battle now entering a crucial stage.
Today, the capsules have long lost their luster and are rusting on the outside, the structure’s earthquake resistance is deficient, there are problems with hot water, drainage, leaks and the air conditioning, and the building is full of asbestos.
“To solve (the problems), basically the only solution left is to exchange the capsules,” says Tatsuyuki Maeda, head of the project to preserve the building.

Forty capsules have fallen into such an extreme state of disrepair that they are now unusable, with some having been used to grow plants — an echo of metabolism, the name of the architectural movement underpinning the tower, of which Kurokawa was a key figure. Another 80 are used as offices, second homes or hobby rooms — the capsules’ soundproofing lends them to practicing musical instruments — and 20 people actually live there.
Maeda himself owns 15 of the capsules, with his first purchase coming in 2011, and he sits on the building’s management board. Initially passing the tower on journeys to school and, later, working nearby, in many ways his involvement in the Nakagin project is the culmination of a lifelong interest.
Currently, the preservation project is in talks with a foreign company — Maeda is unable to say who — that attempts to conserve old buildings and neighborhoods and is interested in buying Nakagin. The current owner of the land seeks to redevelop the complex, and, if a purchase is unsuccessful, demolition is a likely outcome.
The foreign company also supports the replacement of the capsules, which, including additional renovation work, a construction company has estimated could cost at least ¥2 billion, excluding the price of land. A more detailed estimate of the total cost, which will be used to formulate a bid, is currently being drawn up, with a final offer expected to be reached by February, although it could take longer.
“If possible, they are considering paving the path toward (registering the towers as) a World Heritage site, or as a Tangible Cultural Property,” says Maeda, adding that the International Council on Monuments and Sites has already come to inspect the building.
That the building is still around to be considered for such a distinction is a small miracle in itself. In 2007, support for demolition by capsule owners passed the crucial 80 percent threshold, but the Nakagin Capsule Tower found an unlikely savior — the global financial crisis. With the resulting hit to the economy, Nakagin Group couldn’t proceed with its plans for redevelopment.
“Fortunately, they stopped the development and demolition,” says Kenji Watanabe, chair of the Japan chapter of Docomomo, an international organization dedicated to researching and conserving modern architecture. “That’s why it’s still there.”

Between the cost and litany of problems facing the tower, you might reasonably ask what the point of saving it is. But the ideas that lie behind Nakagin give the building vast historical and architectural importance, with metabolism being Japan’s first postwar architectural movement of international significance.
Responding to both the devastation of Japan during World War II and the socioeconomic transformations that followed it, metabolism posited an idea of urbanism that saw cities and buildings as evolving and developing in the manner of living organisms — a radical challenge to existing ideas of city planning, with the metabolists prioritizing process over grand, fixed visions for the urban environment. A sense of the significance of the movement is given by the fact that three architects associated with metabolism have won the Pritzker prize.
“This metabolist movement presented the idealism of architecture in the 1960s: Many goals they set for the movement or for architecture or for city design remain the high kinds of ideals of many architects,” says Zhongjie Lin, an associate professor at the University of Pennsylvania’s Weitzman School of Design and author of “Kenzo Tange and the Metabolist Movement: Urban Utopias of Modern Japan.”
Much of the work of the metabolists, however, remained theoretical, with few built examples in existence — other notable buildings include Tange’s Yamanashi Press and Broadcasting Center — further increasing Nakagin Capsule Tower’s importance.
In particular, the ideas behind the tower of modularity, industrialization and an embrace of recyclability and compact living still resonate today, says Lin, who points to ongoing attempts to build prefabricated towers and the existence of the small, yet adaptable Muji Hut as examples of Nakagin’s enduring relevance.
“Nakagin Capsule Tower represents the dream of a new type of urban living and a completely new urban form,” Lin says.
Metabolism itself tended to overreach, however, with many ideas not being supported by the technology of the time. Although Nakagin’s capsules were envisaged as being replaceable, with owners changing and upgrading their capsule, or even moving it to a completely different location, as they wished, the building design doesn’t quite allow for such a free-wheeling approach to city living — capsules were installed from the bottom up, meaning that moving one requires all of those above it, too. The planned modularity of Tange’s Shizuoka Press and Broadcasting Center, also located in Ginza, has similarly gone unrealized.
And at the time of its construction, Nakagin Capsule Tower was pitched toward a more prosaic demographic — salarymen used to working long into the night and in need of a centrally located space in which to live and work. Pitching the building to those staying in the office until 2 a.m. now seems slightly jarring in a world of high-profile incidents of karōshi (death by overwork), but Maeda insists the ideas behind the tower were ahead of their time and today’s lifestyles have finally caught up, citing trends toward minimalist living, nomadic lifestyles and the embrace of koya (cabins) as living spaces.

For all its impact and audacity, Japan’s hardly stellar record of preserving modern architecture casts a shadow over the project to save Nakagin. Of the 226 buildings so far listed as worthy of preservation by Docomomo Japan, 21 have been demolished. And although a facsimile of the original design was recently built, the demolition of the Hotel Okura’s iconic Yoshiro Taniguchi-designed lobby in 2015 drew an international outcry and highlighted for many how the country’s postwar architectural legacy isn’t always respected.
“The preservation of modern architecture is basically a failure,” Maeda says. “Japan is inevitably trapped in a scrap-and-build culture.”
Talk of preserving Nakagin reaches back to the mid-1990s, when British architect and writer Dennis Sharp, who organized an exhibition on Kurokawa’s work in London around that time, proposed gathering information on registering the tower as a cultural asset.
However, there is a question of how well conservation sits with metabolist ideas of growth and change. World Heritage rules, for example, stress how a building’s “conditions of integrity and/or authenticity at the time of inscription” should be sustained or enhanced, and it is unclear how UNESCO would interpret that in the context of a building designed to evolve like the Nakagin Capsule Tower.

“If the tower is demolished, it would actually be a testament to the theory of metabolism — that the city is ever-changing,” Lin says with a laugh. “But a building is also an artifact. And as an artifact, it actually also embodies human culture, human ideals that we have.”
Kurokawa himself expressed his desire to see the capsules replaced, saying, “if you replace the capsules every 25 years, the building could be recycled for up to 200 years.”
“I designed the building to be an example of sustainable architecture, and it was the first of its kind in the world,” he told Tokyo Art Beat in a 2007 interview published a few months before his death. “I designed the building to have its capsules replaced every 25 years, so it’s ridiculous that 25 years have gone by and nothing has been done.”
Watanabe of Docomomo Japan, meanwhile, stresses the notion of “living heritage” — the idea being that while the facade and underlying philosophy of the architect should be respected, other aspects of the building are much more adaptable.
“Changing the function, changing the material is OK … but please don’t change the important characteristics, the design of the original design, the idea of the architect,” Watanabe says.
Maeda’s own ideas regarding the tower’s possible function post-renovation seem to go along with that, and he foresees the tower becoming less residential and more open to the public, although not completely so, with an emphasis on the curation of art and technology. In a sense, this is an extension of what Nakagin is currently used for, with the capsules being used by hobbyists and hosting TV and photography shoots, a direction Maeda has encouraged. Existing residents tend to work in art-related fields, too.

Looming in the background in the preservation debate is the potential role of government. Over the years, Japan has been very proactive in securing World Heritage listings, for example, but these have tended to be for sites of natural beauty or those linked to traditional culture. Where it has embraced buildings outside those areas, they have primarily focused on those associated with the process of modernization seen during the Meiji Era (1868-1912) — although Japan did throw its weight behind a transnational effort to list work by the pioneer of modern architecture Le Corbusier, which included the National Museum of Western Art in Tokyo.
Last year, the preservation project launched a petition addressed to Tokyo Gov. Yuriko Koike appealing for help in replacing the capsules, attracting just under 8,500 signatures in the process. The petition was subsequently bounced between various departments of the Tokyo Metropolitan Government before, ultimately, it was decided that nothing could be done, as it is not public property.
While Maeda says that the government should intervene in preservation, there is a sense among others that efforts to conserve the tower would be better done through engaging surrounding communities and raising awareness. Watanabe stresses the need to increase appreciation of the value of modern architecture in Japan, arguing that the subject should be taught in schools. Exhibitions can play a role, too, with a metabolism retrospective at the Mori Art Museum in 2011 being a notable example.
Yuka Yoshida, co-founder of Showcase Tokyo, which holds English-language tours of Nakagin, notes how little awareness there is of the building among Japanese people. “I hear a lot of people saying that they asked the way to this building, but none of the people walking around knew about this building, or whether this existed or not,” Yoshida says. “So it’s really amazing — Japanese people don’t know about this building.”
For her part, Yoshida thinks open house events, as seen in other cities, could drive greater appreciation. Still, that can take different forms, with implications for how conservation should be carried out.
“It’s two different kinds of appreciation: It’s appreciation of the building as preserving the history of the past and the appreciation of the building as part of the urban fabric. And right now I think the problem that the Nakagin Capsule Tower encounters is that these two cannot be reconciled,” says Lin, who nonetheless speaks approvingly of Maeda’s intentions for the tower.
“It would be kind of a breakthrough in design and preservation if this can be accomplished,” he says of the plan.
While a path forward for the building has emerged, whether it can take it remains an open question for the time being. What is more certain is the strength of feeling that the Nakagin Capsule Tower elicits.
“The thing that I really feel about doing the tour is that people really have an interest and really have love toward this building, the idea and the theory,” Yoshida says. “A lot of people want to preserve this building, but it doesn’t mean just preserving as it is.
“Everyone really wants to see it metabolize at some point.”
