Anime in Star Trek crossovers

During the saga of Star Trek there were many times when, due to a temporal rift (or something like that), some stuff from the world of anime came over to here.
Some explames are:
*The USS Yamato
*In the episode Yesterday's Enterprise, the fatal shrapnel embedded into Captain Garrett's head was a wing from a VF-1 Valkyrie from the Japanese animated series The Super Dimension Fortress Macross.
