Koma River Cleanup
On Sunday, there will be a river cleanup and vegetarian barbecue at Koma in Saitama. Alishan Organic Center (link on the left) is organizing this event. Everyone is welcome.
I found a nice satellite photo of the Arakawa river system (marked with red lines), reaching from Saitama prefecture to Tokyo Bay.
Can you find Tokyo? Yokohama? Mount Fuji? Narita Airport...?
