Cheap chinese rental cars tokyo

Hey so I've been looking on skyscanner for rental cars in tokyo recently and the cheapest ones always seem to be not really reviewed, weird chinese companies like "Soukyo Rent A Car", "TK JACAR", "JDM Car Rental" and "HM Rent A Car" via trip.com or klook. I've figured since they are on skyscanner they should be legit, but I do have my doubts. Any experience with these rental companies? Couldn't find any good reviews about any of these online, which in itself is already a bad sign.
