What should Yudansha be called instead of Sensei?

In martial arts, the term "Yudansha" refers to a person who holds a black belt rank. While "Sensei" is a common and respectful title used to address a teacher or instructor in martial arts, Yudansha can be referred to with other titles depending on the context and relationship.

Choosing "Mr./Ms." signifies a more general and formal approach to addressing someone while maintaining respect. It is appropriate in situations where the hierarchical distinction of "Sensei" may not apply, such as when the person is viewed as an equal or not in a teaching role at that moment.

The other titles like "Sir/Madam" or "Coach/Trainer" can imply different relationships or roles, which might not suit the specific context of addressing a Yudansha. For example, "Coach/Trainer" suggests a role focused on athletic training rather than the ethos of martial arts instruction. "Professor/Instructors" could imply an academic setting, which does not align with the traditional martial arts teachings where titles reflect respect for rank and experience rather than education level.

Therefore, using "Mr./Ms." provides a respectful and neutral way to address a Yudansha without the specific connotation of a teaching role highlighted
