Sensei, 先生

This is important to emphasize for respect for his teacher…The Sensei/Teacher of Daniel Rominski, Sensei is Roger Wehrhahn, Shihan.

Although Daniel Rominski, Sensei also had the great privilege of studying Iaido many times with his teacher’s teacher Mitsuzuka Takeshi, Sensei during trips to dojo, seminars, camps, visits from Japan and visiting Japan Roger Wehrhahn, Shihan is his direct Sensei.

However San Shin Kai Iaido lineage at TheDOJO is handed down by Mitsuzuka Takeshi, Sensei to Roger Wehrhahn, Sensei to Daniel Rominski, Sensei. Mitsuzuka Munehiro, Sensei (the son of the late Mitsuzuka Takeshi, Sensei) is also a senior instructor, Shihan and advisor of continuing his father’s legacy of the San Shin Kai in North America; whom Daniel Rominski Sensei now also has the great privilege of studying with as well.
