The Nippon Center has a very well executed and authentic Japanese garden complete with an large dry garden or Zen garden. There is a restaurant in the center of the garden called 'Yagoto'. Unfortunately the Center has lost its funding, has closed its gates, and is rapidly falling into disarray.
In the distance,
Neither flowers nor maple leaves
Are to be see
Only a thatched hut beside the bay
In autumn's twilight.
Hana mo momiji mo
Ura no tomaya no
Aki no yugure.
