Note 70 — Japanese Female Names

Sometimes this name is shortened into O-Tsu. In Tōkyō at the present time it is the custom to drop the honorific "O" before such abbreviations, and to add to the name the suffix "chan,"—as in the case of children's names. Thus a young woman may be caressingly addressed as "Tsu-chan" (for O-Tsuru), "Ya-chan" (for O-Yasu), etc.
