The first sign is specifically for Echinotriton andersoni, though most newts squashed on the roads in Okinawa, especially when it rains, are Cynops ensicauda. The red print says "crossing, take care" followed by the black print saying "ibo imori" or Echinotriton.
The second sign is put up by the prefectural agency in charge of that particular stretch of road, the construction of which incorporated a feature designed to enable animals trapped in drainage ditches that often line both sides of the paved lumber roads in this area to escape from them. The red print on it is a request for anybody who finds small animals trapped in the ditches to rescue them and return them to the forest.
The bird illustrated there is the rare and nationally protected Okinawa Rail (Gallirallus okinawae), a flightless species discovered only in 1981. It is calling to its young, saying "hurry on over". One of them is saying "mama" but the print there is too small in that pic for me to read what the other one is saying
The turtle is probably Geoemyda japonica, also a nationally protected species, and the newts are E.andersoni. I did perform a half-hearted search for andersoni but extensive probing didn't seem such a good idea at the time as the notoriously aggressive Habu pit vipers that inhabit the area are especially active in early December, seeking out ideal hibernation sites. Next time for sure
