>> Question: Is money considered "dirty" in Japan?
To slightly change the context, but directly answer the wording of your question - Yes, historically, commercial enterprise was always the lowest of the four classes in Japan. Up until the Meiji restoration in the 19th century, trade (hence money) was considered dirty. Echoes of this attitude survive in the culture today.
