If you're interested in rituals related to the afterlife, but after more adventure and mystery, then check out The Ghost Bride. Slice of life fans will be more at home with The Last Dance.
You'll need a box of tissues for both of these films. They each portray characters dealing with death and coming to terms with their grief via traditional rituals. The Last Dance is more focussed on family dynamics whereas Spirits' Homecoming navigates a political taboo: Korean comfort women.
