Sapporo - Post Report Question and Answers
What is the typical dress code at work and in public places? Is formal dress ever required?
Rather formal, but Sapporo, as the rest of Japan, takes "cool biz" in the summer very seriously. No jacket or tie required June-August. Once the weather cools, however, it's suits for men and the equivalent for women. Some people wear a suit to commute even if they have a uniform or some other clothes at work. - Sep 2011
