The row of luxury shops (and row of apartment towers) at Roppongi Hills is along Keyakizaka, a curved street with a double sidewalk separated by planters. The inside track is for window shoppers, the outside for slightly faster strollers.
There's less street furniture in Tokyo than one might expect: trash bins, vending machines, bicycle parking, etc. are often handled within buildings instead of in the public way.
Interestingly, Minoru Mori is "possibly the world's largest private collector of works of art by Le Corbusier." A 1999 Urban Land article about him by Richard Rosan includes a preface: "[his] plan... runs counter to much of the thinking now popular in North America and Europe. His plan is a response to the Japanese urban landscape of today, which, many would agree, is oppressively dense and congested when judged by western standards. Looking at Mori's plan in that context makes one understand the validity of his vision."
