citrus

Winter citrus brightens cold days in Tokyo

東京に来たとき、柑橘類の木を見て驚きました。冬に果物が熟成しますが、寒すぎるのではないかと思いました。最初、このハッサクは食べれないと東京の人はみんな言いました。去年カナダ人の友だちが、閉鎖された公立学校の庭でハッサクを収穫して、商店街の人たちと一緒にマーマレードを作りました。装飾にも食用にもなります。

Freezing temperatures and icy streets are keeping me indoors. But I am always amazed at how much still grows in Tokyo’s winter months. The most spectacular and surprising is this large citrus called “hassaku.”

For years I believed general comments about how the fruit is too sour to eat. Then I participated last year in Edoble’s hassaku marmalade-making. This tree can be seen everywhere in Tokyo, so it must be well suited. I like how it’s both decorative and edible!

Pasona’s new farm and landscaped building

UPDATE: I posted a revised article, “Sensing Four Seasons at a Tokyo Office Building,” on Huffington Post on July 30, 2010.

Some friends and I visited Pasona’s new office last week. They are a large Japanese staffing farm that had a highly publicized basement farm in their old Otemachi headquarters. This year they moved nearby to Yaesu in their own newly built, nine story headquarters between Tokyo Station and Nihonbashi. Pasona has unveiled a much more elaborately landscaped interior and exterior.

The image above is my favorite because it highlights the interface between the futuristic farm, dependent on a variety of grow lights including LEDs, and the urban environment outside. I am certain that the indoor vegetables will give them the most attention again, but actually I believe the exterior landscaping is more inspiring and impactful.

Below is a brief tour of interior and exterior. After the photo tour, I will suggest some metrics for judging the success of this very visible corporate monument to urban nature.

Glowing all the way across the wide downtown street even in daylight, a spectacular rice paddy with dozens of strong lights occupies the main lobby entrance of the building. The entrance doors are flanked on the outside by beautiful apple trees in giant rusted steel planters.

Almost the entire first floor of the building is devoted to the spectacle of vegetables planting, growing, and ripening under powerful grow lights: rice, tomatoes, melons, corn, eggplants, herbs, and lettuce. A large cafe features wood posts hung at angles and supporting canvas bags with soil and corn. One wall has a series of metal cases with purple lights and tiny fans that have a very “next century” feel.

There is also a room with racks and racks of lettuce, and a field of giant sunflowers. And everywhere vegetables and seedlings are arranged in attractive vignettes. Elsewhere, tomatos hang from the cut-outs in the ceiling. (Click to enlarge the photos below).

What I think works are the following:

  • Pasona demonstrates its commitment to bringing nature into the city by devoting so much valuable space and employing great landscapers and designers.
  • Pasona packages its vision in a combination of high design and new technology that is visually stunning, unique and in many ways hopeful.
  • It is interesting how the cafe and second story meeting spaces are divided and enhanced by greenery. The constant changing as plants plants grow and get replaced, and juxtaposing informal meeting spaces with living plants is a welcome change from most office interiors.

But I also have to point out where the vision falls short.

  • It largely fails as a public gathering place. The giant lobby rice paddy is at once open free to the public and oddly devoid of people, except for a few curious first time visitors. The strange color, strong heat, and loud sound of the lights seems to repel people. In fact, the employees use a side entrance, and bypass the lobby. There is no sense that employees or neighbors will use most of this space, except for suited young people using the cafe and second floor meeting rooms.
  • The intensity of the lighting and sheer quantity beg the question of energy expenditure. Pasona must address how sustainable this idea of indoor agriculture is, and whether they see energy production or usage changing in the future of urban farming.
  • There is no sense of season or natural habitat. It is understandable that birds and wildlife are not permitted inside, but their absence makes the interior seem sterile. Why is the corn ripening in May?

While the indoor farm will generate the most attention for Pasona, I think that the exterior landscaping is more impressive and ultimately more interesting for urban habitat creation and the integration of nature with work space. Two thirds of the building front and at least one side have been carefully planted on handsome screened balconies to produce four seasons of color. Included are citrus trees, wisteria vines, Japanese maple, blueberries, and flowering vines like clematis.  Although the plants are small now, it is easy to imagine the exterior becoming a unique vertical forest and colorful garden over the next years.

The exterior vertical landscaping has 200 species of plants, and many trees that lose their leaves in the winter. The idea is that the plant mass will reduce carbon emissions, summer shade will keep the building cooler, and winter bare branches will allow more direct light during the cold season. While the public is not invited to the upper floors, it appears that the exterior plants are all on balconies that are either accessible or viewable from inside the offices. Click below to see posters that explain the exterior landscape and the designers who worked on this project, and how the exterior garden appears from the sidewalk below.

I am looking forward to watching the exterior of the building grow into its potential. And I am eager to hear how the office workers feel about the outdoor plants that are so close to their interior work spaces.

I’ll end this post with a dandelion weed I spotted on the edge of the rice field. It is this type of unplanned feature that makes natural landscapes so enchanting.

Zoushigaya walk: winter citrus trees (part 2)

On our walk through Zoushigaya, we came across this mature yuzu tree, growing in the small space between the street and a residence. Yuzu is a special, perhaps only in Japan citrus fruit.

It’s also another example of how a tree planted in a styrofoam container managed to send roots through the disintegrating styrofoam, down a sidewalk crack, and into the earth below. It is amazing what a great climate Tokyo provides for plants to go renegade.

We also saw this gorgeous orange tree full of fruit. The oranges, the old house, and the hill above make you feel that you are far from the big city.
