In a Nippon article by Sakurai Shin, translated, we learn about urban bee culture in Central Tokyo.
“The urban bee farm is the work of the nonprofit Ginza Honey Bee Project, or Ginpachi, founded in March 2006 by Tanaka Atsuo.
“It started when Tanaka, who rented out space in Ginza, learned from a beekeeper that it might be possible to raise honeybees on the roof of the Kami Parupu Kaikan building. From this location, Tanaka learned, the bees could gather nectar from Hibiya Park and the grounds of the Imperial Palace, both within a radius of around three kilometers. Bees are highly sensitive to pesticides and other environmental pollutants, but the Imperial Palace is relatively free of agrichemicals. In this sense, Ginza turns out to be a surprisingly good area for beekeeping. …
“In the 10 years since the Ginza Honey Bee Project began on one corner of a Ginza rooftop, the ripple effect has spread to other parts of Tokyo and far beyond. There are now more than 100 urban beekeeping projects nationwide, and more in South Korea, Taiwan, and elsewhere in Asia.
“ ‘Ten years ago, of course, we never imagined the project would have such an impact,’ Tanaka says. ‘I think it’s because people have been able to make it into their own project, reflecting local conditions and responding to local issues.’
“Tanaka also credits the honeybees themselves, emphasizing what human beings can learn from contact with these industrious insects.
“ ‘For example, when I see the bees returning to the rooftop from their flight around Ginza, I can tell from the pollen stuck to them that it’s safflower season, or the tochinoki [Japanese horse chestnut] trees are in bloom. Spending time with the bees puts us in touch with the natural world and its changes. Ginza may seem an unlikely place to be tackling environmental issues, but it’s becoming that sort of neighborhood.’ ”

This lovely story came to me by way of blogger Asakiyume.

I’d never really thought before of whether, or how, bees would exist in an urban setting. This is fascinating!
Was interested that chemicals (which are bad for bees) are not used at the Imperial Palace. Maybe they are bad for the Emperor — and the rest of us.
