Ecotwaza at Aoi Shobo, Roppongi!
10 Aug 2010
I am pleased to announce that Aoi Shobo (by Roppongi, Exit 3) has been kind enough to agree to sell our magazine Ecotwaza.
Thank you!
The shop is somewhat hard to find, so I will give a quick description.
First, the exterior.
Located on the first floor of a building, you can see the "book" sign in the back.
The cashier is right inside.
Of course, you can simply ask here for the bilingual magazine, Ecotwaza.
Since it is new here, however, it is possible that the salesperson will not know of it.
In that case, please look in the Western magazine section.
This section is in the back of the store.
...and, looking down, at the bottom...YES.
Please do not give up, it is there somewhere.
It would also be great if you could spread the word to your friends once you have read the magazine, and keep the cycle going.
Thanks!

A Line of Drawers
10 Aug 2010
Good morning everyone!
I hope the humidity hasn't gotten to you too badly.
It's been at the back of my mind for a long time now that there were two large
wooden drawers in one of the rooms of our Kunitachi office.
They are very old and belonged to my grandmother, but I've never been able to muster
the courage or energy to throw out these family antiques.
I asked my friend Kazuhiko - an architect and a fellow Kunitachian - about the drawers,
and it so happens that they can be remade.
He also convinced me that there were sure to be buyers!
They are beautiful drawers, so apparently they are still of value if given enough space
(or simply just a little more space than our cramped and humble abode).
Feeling sorry for having cooped them up in a dark and dusty room for years, I decided
to give them some air and sunshine.
They look like koinobori.....?
Since I don't take apart drawers on a daily basis, it wasn't until today that I realized that
they come apart to become three separate parts.
This definitely helped when carrying them out into the open (imagine having to carry
a whole chest of drawers through the house...)
I was also amazed to see that the drawers were not all the same size, and that each
drawer had its specific place.
I had already asked most of the kimonos in the drawers to be remade, but I've decided
that I will get the rest remade too.
Remaking my kimonos and the chest of drawers, I feel refreshed and energized.
I'm sure you also have old things lying around in the house.
How about taking a look at them and recycling them before thinking of throwing them
out?
It creates a flow that helps the balance between functionality and tradition.

The Making of the Cover for Ecotwaza Vol. 10
|
|
20 Jul 2010
Today, I would like to take you behind the scenes for the making of the cover for Ecotwaza Vol. 10, published at the end of last month. As usual, I start by sketching an artistic masterpiece (?) and submit it to the designers.
Our photographer, Kuro, works hard to get a photo. He looks like a very suspicious character in this one!
You may be wondering what he was trying to photograph crouched in this awkward position in the middle of the city... The title of his picture: Shinmaru Building from Behind the Hedge! He responded magnificently to the extremely difficult task I gave him of including the shrubs in the shot. Thanks Kuro!
All that was left for us to do was to hand this photo to our genius designer Mr. Suzuki, who worked his magic to turn this picture into a cool and trendy cover. As it turns out, for various reasons, I happen to be in the picture... Anyone who is able to find my discreet presence may have a happy windfall...maybe??? We have been very surprised by the success that this issue has enjoyed so far. It must be because of the cover.... Look out for an even better one next time!

Mitsubishi Estate's Eco-Friendly Efforts
13 Jul 2010
On July 2, a preview for the Hybrid Air-Conditioning System utilizing ceiling panels was held at the head office of Mistsubishi Estate.
Mistubishi Estate has renovated a room in its corporate headquarter building into an energy saving system. Currently, systems for saving energy have been instituted in new buildings, but not in the buildings which already exist. Here, Mistubishi Estate have tried to validate the system for an existing building. These technologies are known as "Ceiling radiation hybrid air conditioning system" and "LED task and ambient lighting system."
"Ceiling radiation hybrid air conditioning system" is being introduced in Japan for the first time. It is expected to reduce CO2 emission, improve comfort, and reduce maintenance costs. The amount of power needed is reduced to a quarter of the normal air conditioning. In addition, the energy necessary will be created and stored in a more efficient fashion through late-night storage.
Though this system seems to be widespread in Europe, they have to examine whether the function will work in the hot and humid climate in Japan. Experiments to answer this question are being run in a room in Mitsubishi headquarters. The system incorporated is a Japanese version of technology developed by MWH Barcol-Air AG, Switzerland.
In terms of the "LED task and ambient lighting system," ceiling lights are set to 300 lux. Individual workers can adjust the brightness of the lamps at their desks depending on their personal needs. Through these adjustments, CO2 emissions are expected to be reduced to half the original amount.
Through this type of energy conservation, we will not have to endure heat and discomfort for the sake of being environmentally friendly. These new technologies will enable us to care for the environment in comfort.

Ecoland, Less is Beautiful
08 Jul 2010
Tokyo, the capital in which Ecoland operates, is arguably one of the most expensive cities in the world—not only the price to get brand-new goods but also the price to get rid of the old ones. This goes to the point that most of the time it is more expensive to buy new furniture than to move them to one’s new place. Ecoland is a business model built around the very mantra of ecology: reuse, recycleand a touch of its authentic concept—re-arise. Their slogan says ‘less is beautiful.’
Ecoland literally does business by collecting what people do not want. The keyword for their business is the ‘zero mission,’ a mission to reduce the number of unwanted “garbage” to nothing. In Japan, there are delivery service cars who would come to one’s home and pick up the mailing goods. Likewise, Ecoland is a delivery service, for the unwanted goods to the new owners.
If you are wondering where these unwanted goods go, it first go online. Eco-auc.jp acts as the company-owned eBay for the collected goods. It features any household things from furniture, personal computers to bicycles. This is the first skirmish for the zero mission.
Recycle shops are a common sight in a Japanese city. It is the place where people sell their old goods and others come to buy those second-hand bargains. This is one of the channels through which Ecoland turns the unwanted furniture into a new form of products.
Lastly, if an unwanted piece of furniture fails neither to impress the Internet bidders nor to make it to the second-hand shelf, re-arise comes in. Think of this as a taylor-made furniture, made from unwanted ones. When your old piano becomes a deadweight of a move, Ecoland can collects it, takes them apart, and reassembles them into a compact musical box with the memory of the old piano. It is not only recycle; it is making new products arise from old memories.
What skeptics said about the Japanese ‘eco’ to be overhyped as well as overrated certainly does not apply to Ecoland. The business model represents a delicious matchup between economic niches and environmental awareness.

MALSEC Report
|
|
06 Jul 2010
In May,an exhibition for light-weight and high-strength material and technology(MALSEC) was held at Tokyo Big Sight. In this report, let us introduce you to one of the exhibitions,“Meguru”.
4 small companies in Osaka stood up to co-develop an EV (electronic vehicle) tourist taxi for the world-famous city Kyoto. The EV is named“Meguru”. The kanji standing for “Meguru” is “環”, which means “to return in a circle”. The Japanese word for “Environment” (“環境”) includes this kanji as well.
This three-wheeler motor-driving EV, weighing only 230kg, has a maximum speed of 40km per hour. Integrated inside is a lithium-ion rechargeable battery and its mileage per hour is 40 to 50 km. Apart from the ecological aspect of this little vehicle, its appearance is also very unique. Conjuring the image of a Japanese shrine, the surface is lacquered-coated and the door is replaced by a gigantic Japanese fan made of Kyoto Washi (a Japanese paper). “Meguru” not only has the possibility of making sight-seeing in Kyoto eco-friendly, but it also resembles the collective effort of traditional craftsmanship and latest technology owned by small companies of Japan.
The leader of this project, Mr.Ogura, who is also the CEO of Yodogawa Co. Ltd, a small factory making preproduction prototypes for big companies, says that he“wanted to show the passions of small factories in Japan, and what they can do”.

Sakai Office Live in Canada
02 Jul 2010

Whereas some art forms encourage symmetry, perfection and complex design, Japanese gardens are noted by their thorough emphasis on asymmetry, natural imperfection, and simplicity. That is what Sakai Office is striving to show the world.
Yasushi Sakai, chief designer and CEO of Sakai Office, had his overseas debut since cooperating with Ecotwaza last week in Canada. Mr.Sakai has been creating Japanese gardens in Tokyo metropolitan spaces for 30 years. This time, he decided to take it to the next level by remodeling a Canadian garden, giving it the simplified Japanese aesthetics. It is the prelude of the project to transform the garden into a learning center for Japanese culture and philosophy over the next several years.
For the remodeling, Mr.Sakai began by a group planting of fundamental flowers required in his usual repertoire of Japanese gardening. He then moved on to pruning the bushes at the entrance of the garden—less is better than more, as the Japanese saying goes. After that he gave it a finishing touch by trimming the ground cover in bonsai style. Japanese gardening greatly values the passage of time. According to Mr.Sakai, the truly completed garden can only be observed at least three to five years from now. The wait is surely painstaking, but appreciating the time is also at heart of Japanese gardening and philosophy.

Kami no kousakujyo: Beautiful Eco-Friendly Paper Artifacts from Japan
01 Jul 2010
Anyone who has watched an episode of the hit NBC television series “The Office” will know how hard it is for a small-sized paper company to compete in the world today. For those unfamiliar with the show, it is a comical and satirical documentary of a small fictional paper company and its struggles against superpower retailers. Recently, however, I was lucky enough to have the chance to observe such a small paper-industry business first hand, and was struck by the importance of such often-overlooked and ridiculed enterprises. Fukunaga Printing Company is a small-scale paper and printing company based in the outskirts of Tokyo, Japan. With only thirty or so workers on a small plot of land, it is definitely not competitive with large-scale companies in terms of production. However, what they lack in sheer mass and numbers they have made up for through a combination of brilliant creativity, traditional technology, hard work, and personal touch. Especially eye-catching is its “Kami no kousakujyo” project. Using ideas received from designers from across the nation, workers at Fukunaga collaborate with “template-making” craftsmen to hand-make templates for paper artifacts, according to the particular design. These templates consist of a wood base and razors in a specific design, so that when paper is pressed against them in the paper-cutting machines, certain patterns are cut into it. When folded, this paper transforms itself into objects of wonderful aesthetic and practical appeal, ranging from paper vases to flashlights to miniature models to greeting cards. All of their products are extremely eco-friendly; in fact, some, such as the paper vase, are manufactured from the leftover scraps from other products. Equally as picturesque as the products is the factory itself. The 50-year-old machines (which still function perfectly well) and the workers who have been in this industry for decades give a truly intimate feel, and it is hard to imagine such delicate artifacts being created in a factory on a larger and less personal scale. In fact, some of the products are still hand-made as the intricate processes cannot be maneuvered by the robotic arm. The “Kami no kousakujyo” project from Fukunaga Printing Company is a wonderful collaboration of creative ideas, environmental consciousness, and intimate personal touch. However, it is only one of many small- and medium-sized businesses present in Japan today that have supported the country for decades but are now being forgotten under a mass of large-scale retailers. Although these chain stores do have some advantages, there are countless ways in which the small- and medium-sized enterprises are irreplaceable. Perhaps it is time to pay them more attention once again, and to recognize and respect their true worth and potential.

Taking on the Challenge of Building a Solar-Powered Log Home Part 2
01 Jul 2010
When building their home, the builders wanted to flatten the lot, remove all rocks, and drain off excess water. However, the Sheppard’s insisted on retaining the terraced landscaping and on keeping and using unearthed rocks, thereby minimizing runoff.
Installing 4.25 KW of solar panels allowed them to go fully electric and implement a ‘no burn’ policy for cooking and heating, and lots of wood and windows provide passive solar energy to warm the house. Double walls ensure the retention of cool in the summer and warmth in the winter.
The house features 450 tsubo (approx. 1,500 m2) of former vegetable garden and orchard. The logs for the house were imported from Finland, a decision that came down to economics. To repay the atmosphere for carbon used in transporting the logs, the Sheppard’s have planted over 300 trees and bushes including kiri, mimosa, sakura, Himalaya pine, and more.
The result of their endeavors is Hillside Place, a highly sustainable, solar-powered log home with clean air, wonderful views and a peaceful atmosphere. Their next project is to build a guest house that is totally ‘off the grid.’ For more info check out www.hillsidebridal.com

Kannbatsu: Cutting Trees Instead of Planting
28 Jun 2010
In an age when rainforests all over the world are disappearing at alarming rates due to the human rush for resources, it may be counterintuitive to learn that there are cases of necessary tree-felling that are not carried out. Yet this is a very real phenomenon observed across Japan today. Approximately 64% of Japan’s total land area is covered in forest, of which 45% are plantations. These artificial woods were planted during the country’s period of rapid economic growth following World War II, mainly through former Prime Minister Kakuei Tanaka’s plan to remodel and reform the Japanese archipelago. Most of these plantations are of a single uniform species, with Japanese cedar (sugi), Japanese cypress (hinoki), and Japanese red pine (akamatsu) being the most common types of tree used. With the trees growing within close proximity of each other, and at the same rate, a common problem is that all the trees grow to be thin, weak, and of sub-par quality and price for the harvesters (these are often called “bean sprout forests” in Japan). The forests can also become tangled and unmanageable masses as the thin trees intertwine with each other. In addition, the uniform height of the trees prevents sunlight from reaching the lower regions, denying the growth of grass and shrubbery. Without this growth, the land becomes very prone to landslides. In order to maintain high-quality wood and to deter the dangers of these natural disasters, it is necessary to, once in a while, thin out the forest by felling the smaller trees, giving the taller and more “promising” trees more room to grow while allowing the growth of grass, ferns, and such to prevent landslides. This is the process known in Japan as kannbatsu, and is absolutely vital for the well-being of any plantation. This practice is often neglected, however, as it incurs economic costs (labor costs, etc.) without financial reward. Recently, to help prevent the intentional overlooking of kannbatsu, many groups have taken initiative, utilizing the wood harvested from the process to create products and sell them for profit in order to fund the system. Although this wood may not be thick or strong enough to serve as the framework of a house, for example, it can be used perfectly well as material for smaller goods. Providing people with a wide variety of innovative and useful goods while helping prevent landslides and thus sustaining forestry and the environment, these products made of sustainably harvested wood are great for both their fashionable and their environmental qualities.

Restored Kominka Homes Combine Modern Comforts with Traditional Design Part 2
26 Jun 2010

Jacob’s team preserves the traditional feel of the minka homes while creating modern comforts and safety. Double paned windows are added to fill the homes with sunshine, while keeping in warmth, walls are thickened with insulation to stop air leaks and yukadan (floor heating) are installed to make the homes warm even on the coldest winter nights.
This spring they completed the reform of a 150 year old thatched-roof house which sits at the very top of the village with views of Lake Shoji. The exterior of the home is elegantly Japanese, with oni (gargoyle) statues on the roof and a small koi (carp) pond in the garden. But upon entering one is amazed to find a light-filled, modern kitchen with an open plan and hardwood floors which opens onto a deck overlooking the gardens. The large hikoki (cedar) bath gives one the feeling of being in an onsen (hot spring). An irori (sunken hearth) in the middle of the house sits in a room filled with antiques. Along the eastern face of the home runs an engawa (low veranda) with large sliding glass doors to let the morning light into the private tatami (straw mat) rooms. Most spectacular is the upstairs loft with 3 meter ceilings and the old hand-tied beams still exposed.
For more information on these kominka homes and the nearby Earth Embassy Organic Farm and Guesthouse, visit their website at www.earthembassy.org
Want to buy your own restored kominka home? For sales information or to arrange a viewing, call Jacob on 090-9346-3774.

Restored Kominka Homes Combine Modern Comforts with Traditional Design Part 1
23 Jun 2010

If you are wondering where to find a true example of eco-friendly lifestyles, incorporating all the modern catch phrases -- sustainability, organic agriculture, LOHAS and slow life -- the best place to look is actually to the past. Traditional Japanese villages from the Edo period were self-sufficient, completely organic and the homes were built with readily available materials from nearby forests.
One such village that has escaped the hectic development of modern life is a small enclave of traditional Japanese kominka homes on the shores of Lake Shoji in the Fuji Five Lakes region known as Fujigoko. While nearby Lake Kawaguchi and Lake Yamanaka are cluttered with hotels and chain restaurants, Shoji is a quiet, bucolic community where the locals still grow their own edamame (baby soybeans) and make their own miso.
The one street that runs along the small river in the center of the village is filled with classic Japanese homes dating back to the Edo period. The local family restaurant, Kotobuki, is run by a family that has actually been there for three generations. The menu includes wakasagi fish from the lake, pumpkins grown in the garden outside, organic mint tea from the nearby Solar Café & Farm, and venison from the local mountains.
Ten years ago when Jacob Reiner, an eco-home designer from Cornell University, first found the village, he fell in love with it and decided to restore the homes one by one. Since then his Eden Homes team has been diligently repairing the homes and bringing in families to create new life in the village.

Konjac: A Healthy Alternative
21 Jun 2010
Konjac: A Healthy Alternative
Despite all claims that America is the most obese nation in the world – or perhaps as a result of it – the people of the United States seem to be very health-conscious. As a college student in New Jersey, it has been especially interesting to see the use of tofu as a healthy alternative to meat. Throughout the US, meals such as pasta with tofu and barbeque tofu have become commonplace. This varied use of tofu is a result of two factors. One is its taste (or lack thereof) and texture, which lends itself easily to different types of recipes. The second is its health benefits – compared to other foods, it is extremely low in calories and high in protein. Tofu, however, is not the only food that meets these requirements. I would like to introduce another alternative: konjac. Although not as famous internationally as tofu, konjac is a traditional Japanese food that has become a key ingredient in any health-conscious Japanese’s diet. Derived from a plant grown in many parts of Asia, it can be used to create flour that can be formed into a gel of unique texture, slightly firmer than that of gelatin-based products. Being low in calories and high in fiber, konjac is used in a variety of Japanese foods, ranging from oden to fruit jelly snacks. It can be cut into strips to create konjac noodles. Some companies have taken a further step, mixing konjac with bananas and okara (residue left after production of tofu) to create a substance they have named KON-NIKU, which has a texture and protein content similar to meat, minus the calories (http://www.eco-friendly-japan.com/product/99). Konjac is only one of many health-friendly products that exist in Japan today, but are as of yet unknown to the world. In fact, with its high adaptability, great health benefits, and addictive texture, it is surprising that konjac has not yet caught on globally. If given the chance to cross the Pacific, konjac will most definitely have a strong impact and enjoy immense popularity among the health-conscious in the United States.

At TBLI Conference Asia
|
|
15 Jun 2010
On May 27, 2010, I served as a moderator at the TBLI Conference Asia 2010 which was held on May 27-28 in Four Seasons Hotel Tokyo. TBLI Conference is the largest annual global networking and learning event on Environmental, Social and Governance Investing of Asia and Europe. This year’s theme is “Values and Leadership in Finance.”
TBLI Conference has been in existence since 2000 and it consists of two annual conferences. These two-day events give the world’s leaders on sustainability an opportunity to network and exchange information on the latest developments in screening, auditing, reporting, SRI analysis, corporate citizenship, indexes, and research.
 There were a total of 220 attendees from 16 countries and 72 speakers and moderators. There were 3 speakers in Workhop 4—the session I chaired— each representing different field of expertise in green real estate.
Keiko Hosoyama from Japan shared her views on “Environmental Enhancement and Value-Added Practices for Our Trusted Property,” Sethawat Srivirote from Thailand talked about “Analyses and Reflections from a Leading Thai Real Estate Developer / Green Design Firm Towards Sustainability Development,” Takehisa Hirayama from Japan made a presentation about “Green Indoor Climate Projects in Japan - Overcoming Regional Climatic Variety and Project Complexity.”
The speakers and the participants discussed, among many other things, one, the assessment of policies and barriers for green buildings/green developers in Thailand; and two, the potential of converting existing architecture into current usage and reducing energy consumption and substantially improving indoor comfort conditions at the same time, employing a case study of converting a 90-year old bank building in Kyushu, Japan, into a multipurpose office and research building.
The session was professional and educational with the speakers’ global knowledge and practical experience. I enjoyed the active participation of attendees in fruitful discussions and the interdisciplinary and inspiring atmosphere of the conference. I am sure that the participants interested in sustainable practices have benefited from attendance and professionals engaged in the business of real estate have found this session to be relevant, inspiring and motivational in terms of sustainable options.

Evaluation Factors of CASBEE Part 1
|
|
09 Jun 2010

CASBEE or Comprehensive Assessment System for Built Environment Efficiency was found in2001 as a system to provide rankings for buildings based on their environmental friendliness. We feel that it might be interesting to show the criteria by which buildings are evaluated according to their 'environmental efficiency' in Japan.
CASBEE criteria are divided into two groups: load factors and environmental quality.
Load Factors (Environmental load reduction performance)
○ Energy
● Suppression of building heat load
● Use of natural energy
- Direct use, converted use of natural energy

- Air conditioning, ventilation, lighting, hot-water supply, elevators, facilities to make effective use of energy
● Efficient operations
- Monitoring, Operation Management System
○ Resources, materials
● Protection of water resources
- Conserving water, use of rain water, reuse of waste water
● Reduced use of non-renewable resources
- Timber from sustainable forests
- Initiatives to improve the potential for reusability of materials
- Use of recycled materials
- Continued use of existing building frame
- Reduced material usage etc.
● Avoiding the use of material containing pollutants
・ Use of materials containing no hazardous substances
・ Avoidance of CFCs/halon gas
○ Off-site environment
● Consideration of climate change
● Attention to regional environment
- Prevention of air pollution, improvement of thermal environment degradation, suppression of load to the regional infrastructure
● Consideration for ambient environment
・ Prevention of noise, vibration, and odors
・ Control of wind and storm damage and obstruction of sunlight
・ Control of light pollution
