Gassho is simply putting your hands together, in some cases with a mala (beads) involved.
In Jodo Shinshu the mala or Onenju rests between the thumbs and fore fingers, encircling the fingers on both hands for example.
I'm not too familiar with Nichiren-shu, but in Shinshu we gassho when listening to passages from the Sutras or writting of the patriarchs, when reciting Nembutsu after chanting a Sutra, and after dropping a pinch of incense into the burner.
Also upon entering or leaving the Hondo.
