Modern or Too Old? - Japanese Names

I’m doing research on Japanese names for a story I’m writing, and I don’t know if the following names I’ve selected would be considered “outdated” or “grandparent-sounding” for the time period it takes place in (early 2020s). I want to sound realistic with my names and their usage, so any feedback about whether or not these names would befit Japanese individuals aged 15-20 would be appreciated!

-Emiko.
-Etsuko.
-Homare.
-Hitoshi.
-Hajime.
-Hanako.
-Kenji.
-Kojiro (nicknamed “Ko”).
-Kazuhiko.
-Noriko.
-Sachiko.
-Satoshi.
-Tsutomu.
-Tsubasa/Tsukasa.
-Uigo.
-Umeko.

Any other info about modern Japanese naming customs and alternative suggestions would also be much appreciated!

Not sure how helpful this is, as I don’t know lots of about Japanese names, but here is some info on Top Japanese names from the 2000s:

Thanks for the tips and lists! Good to see that a few names I like rank pretty high in these lists!

I have heard somewhere that “-ko” ending names have become a little dated in Japan, but I am not Japanese so I can’t speak to that personally. I did find at least one article that backs it up, though.

I would second the idea of looking at the recent statistics.
