Abstract
Street trees are expected to play an important role in making fine townscape in the Master Plan for Townscape in Muroran City. This study investigated street trees at 16 main arterial roads and made their characteristics clear. Natural landscape in Muroran is quite nice but townscape, especially in built-up area, is relatively poor. One row of street trees at both pedestrian ways is not so enough that combination of street trees and other elements is important. Others mean trees at roadside building sites or parks, hedge or flowers at residential zone and street furnitures or street lights at commercial zone.
