It is on SteamDB, right here[0]. It says in giant text "This page was taken down because SEGA is claiming we distribute their game here (we don't)."
However, if you search for the game in the SteamDB search bar (just enter "Yakuza", don't even need the full name), it will show up just fine, with a picture and all, you just won't be able to see the full page. That's how I found that link, so I have no idea how you missed it.
