I've never done or heard of a way to do this, but here is a try at a complete guess.
Clean the area very well with acetone or isopropyl alcohol. Smear some mustard or other acidic paste into the cracks of the kanji. Wipe the face very well leaving the acid paste only in the kanji. Let sit for 15-20 min then wash it all out really well. This would likely give you a dark patina on all the metal surfaces that brightened over time in there.
Again, I am completely guessing on this and others will likely chime in with better ideas and experience.

Black sharpie.
Since I don’t see any patina, I’ll assume it’s a stainless knife. In that case your only option is to color it in with something. Maybe something like car touch up paint?

Good call on the stainless @Heckel7302 . If that is the case, I'd try black nail polish. Again, clean very well with acetone or isopropyl alcohol and then apply. Nail polish will be durable yet easily removeable with safe chemicals down the line.
Nail polish is a good call. There are non-toxic nail polishes that would lower concerns about any flaking off into food.
The logo is not deep enough to work.
Aha. Well nail polish will still be darkest and probably hold up best, and could be removed with acetone if it doesn’t look good. Alternatively you could force a patina in there with mustard or vinegar or coffee then remove the excess off the flats with flitz or simichrome.
Very easy. First use an Dremel brass brush to clean up the embossed writing You need to completely degrease the area using medical grade alcohol, this is the 99% stuff. Next use engraving tape. it goes on the area around the inscribed metal. Use a fine Exacto knife to cut away the tape from the writing. I use Brownells OXPHO-Blue Creme gun blue. I have used this product for many years on my firearms. use a toothpick the apply it is in a gel form. you can reapply it until you get the coloration you like. It rinses completely free leaving nothing behind to make it unsafe with food. It makes the area treated rust resistant.

Fine tip black sharpie.
Dip the knife in boiling white vinegar for a bit, then polish the patina back off.
Yeah that's basically it, but it'll be more uniform if you just etch the blade entirely
What’s the best way to clean off that forced petina from the whole blade? Simichrome?
Depends on how polished you want it, I'd use a rust eraser or something like bkf on a wine cork. Just nothing soft like a polishing cloth that'll dip into the logo.
Just say no to rust erasers. Way too abrasive. High risk of undesirable scratches. I like flitz. Simichrome works too. For household solution a paste of baking soda and water.
Forgot about Flitz, good call!
The grove on the second logo isn’t deep enough, unfortunately.
It will take the patina off if you dunk the whole knife in an acidic solution.
I just want to remove the black logo. Surely you can’t dunk the handle lol
The Flitz/acid dunk recommendation is related to the forced patina route to solving your problem:
Acid dunk forces patina, Flitz removes patina.
The procedure would be to dip the logo (or the whole knife minus the handle, if you want to force a uniform patina on the entire blade — this seems unnecessary to me) and patinate the stamped area. Then use Flitz to remove/reset the patina on the rest of the blade so you’re left with the patina-darkened stamped kanji.
To get the dark, inky black that it had originally, it seems like you’ll want to go with either Transmaster’s method or the nail polish route. I wonder if you could use a tiny pipette to get nail polish in the stamped area and then use acetone and pointy q-tips to clean off any excess.
Apply nail polish with a toothpick.
Bluing is usually pretty spectacularly toxic.

Thick knives save lives
Proper rust bluing on the other hand, is perfectly fine.
I have a special hatred for cold blue.
