Japanese haiku by women

My longest, most complete haiku anthology includes haiku by men and by women. I don't really find any thematic or formal difference between what each gender wrote.

Chigetsu-ni:

Todas las flores
están en su esplendor
y yo envejezco.

All the flowers
are in full bloom.
I'm getting old.

Sono-Jo

Siento en el pelo
la caricia del niño
a mis espaldas.

I feel on my hair
the caress of the child
behind me.

Chine-Jo

 Por estos bosques
tan profundos no cruza
ni un pajarillo

Not even one bird
is flying through
such a deep forest.
