eco-system

Barren space between sidewalk and Roppongi Hills

どうして六本木ヒルズの入り口は死んでいるのだろう?

Why is the entrance to Roppongi Hills so ugly and uninviting?

Every time I walk from the subway into Roppongi Hills I am shocked at the extremely ugly first view of this mega-complex. In addition to the elevated freeway, pedestrians are greeted by this horrendous, wide, astroturf-covered dead space in front of Roppongi Hills North Tower.

How could this make people want to enter Banana Republic? And what does this say about Mori Building’s vision for integrating their properties into their neighborhoods and communities? I feel that this forgotten and dirty space implies that the real landscape only begins at the podium level and that the North Tower is not of equal status to the rest of the complex, despite being in the front. It’s as if they imagine that their important customers enter the complex only by car.

This lack of respect for pedestrians, neighbors, and context is completely unnecessary. The smallest gesture would improve this space and make it more inviting and alive. If Mori Building reads this post, I hope they will consider improving this entryway to their otherwise well landscaped property. If anything, improving the entrance might also provide an opportunity to consider how to extend their landscape ideas further out into the neighborhood, creating connections with other shops and residents, and building a larger and healthier eco-system that would benefit Mori and their neighborhood.

Last night I attended the last Pecha Kucha Tokyo of the zeros decade, one block west of Roppongi Hills, and remembered that I had taken this photo weeks ago. Each time I am shocked as if for the first time. Outside of the expensive office towers and glittering malls, I wonder how such an ugly neighborhood can be attractive to multinational companies and foreign ex-pats.

Satoyama and biodiversity

Satoyama and biodiversity

Satoyama (里山), a term I first heard from 5bai Midori, describes a Japanese eco-system that supports biodiversity and is paradoxically the result of human transformation of forests over 2,000 years of rice farming. A fascinating Japan Times article explains what satoyama is, and how it is threatened on the one hand by large-scale agribusiness and pesticides that are sterilizing the land, and on the other hand by the encroachment of forests on villages that farmers are abandoning in rural Japan.

Satoyama are heavily managed forests and fields that replaced Japan’s densely shaded wilderness with a system of concentric rings of sato (village), satoyama (managed woodland), and okuyama (wild forest). In proximity to dwellings, cutting wood for fire provided openings in the forests that encouraged sun-tolerant trees and created habitat for wildflowers, butterflies, birds and other species that do not exist in wild forest. Cultivating rice paddies, and building the irrigation systems of reservoirs and canals that supply them, created aquatic and semi-aquatic habitat for amphibians, insects, water plants, crustaceans and fish. The system depends on the close proximity of all three rings, spread out over a large portion of Japan’s mountainous island habitat.

According to Japan’s Environment Ministry, more than half of Japan’s threatened plant and animal species live in satoyama areas. The Environment Ministry has created at least three editions of a national biodiversity strategy and launched a Satoyama Initiative that has included knowledge sharing with Asian regional conferences. And Japan will next year host the 10th Conference of Parties of the Convention on Biological Diversity (COP10) in Nagoya.

Resources in English include Takeuchi Kazuhiko et al’s book Satoyama: The Traditional Rural Landscape of Japan (Springer, 2002). And there’s a Japanese Environment Ministry video on satoyama on YouTube (no embedding unforuntately).

Kajima and bees

Kajima bee project on Japanese MX television

Yamada Yuriyuki (山田順之) , a biodiversity specialist at Kajima, one of Japan’s largest construction companies, appears in a video on Japanese TV about Kajima’s beekeeping and biodiversity education work. Kajima has started a hive in one of their buildings, and is studying how and where bees travel.

Yamada-san makes the important point that “greening” is not just about aesthetics but about eco-systems. Bees play an important role because they pollinate fruit trees that in turn attract birds. Bees also scare away crows. And it is because of the decline of bees in the wild that farmers need to manually pollinate fruits and vegetables. The video also shows how Kajima has educated school kids about the value of bees.

I am curious how far bee-keeping can take off in Tokyo, and the connections its advocates can make with native plants, urban wildlife, and city agriculture.
