In this instance I was riding to a shop on a busy 4-lane stroad. Since I was turning right at the last intersection and moving to the sidewalk I moved to the right side with the intent of getting on the sidewalk. This is another area with a narrow 50cm / 18 inch wide sidewalk. There were already two women walking on it so I had to skirt the edge of the road until I passed them. This is not uncommon in Japan. Often, on sidewalks such as this, if two pedestrians pass one another, one has to step down into the road. The parking lot the driver was going into is not for public use. It belongs to a taxi company and only taxis may park there. Until he honked his horn, I wasn't upset. He was making an illegal turn and didn't check the sidewalk for bikes or pedestrians, almost hit me and then blamed me for his mistake.
