According to the ruling, in July 1990, the victim and the five plaintiffs went
on a Hoyu-no-kai-organized outing to a spa resort in Miyazu, Kyoto Prefecture,
along with other members of the group and their families. At the time, the five
reproached the man for the absence of his younger sister, also a believer, from
group activities. They then hit the man in the face and threw him in the sea.
