Comments for the name Itsuki

It can be a girl's name.

Itsuki Koizumi is one of the main characters and an esper on the show, the Melancholy of Suzumiya Haruhi.

Pronounced its-kee.

This COULD technically be used on a girl as well with different kanji. It doesn't seem like a super-common name these days. I would use Itsuki on a girl using the kanji 生連基 and it probably never would have crossed my mind for a boy. That said, ki can be an ending for names of either gender... though certain kanji are more likely to be used on 1 gender or the other. However, I guess the kanji I have here could probably be used on a boy as well.
