How do you find certain JAV Actress' Date of Birth?

[ArgentGrace]

I usually use alot of sites' resources to find JAV Actresses' date of birth like
asianscreens.com or sougowiki, etc, etc
but there are 4 jav actresses that I can't find date of birth, no matter how many times I google or check any site.

Any one know for these?

Momo Minato

Tenno Uta

Ichika Nagano

Kudou Rara

Kudou Rara 30.04.2001 - https://ja.wikipedia.org/wiki/工藤ララ
Ichika Nagano 23.11.1997 - https://ja.wikipedia.org/wiki/永野いち夏

For most actresses you can just google their name written in japanese and you'll get their wiki page, which more often than not includes their date of birth.

Some sites claim 3/29/2002 for Uta Tenno.
