A Buddhist ceremony held on specific anniversaries after a person's death, such as the 49th day or the first Obon.
Next month we have a Buddhist memorial service for the third anniversary of my grandmother's death.
We will hold a memorial service for my grandfather next week.
I went back to my parents' house to attend a relative's memorial service.
We hold a memorial service for my mother every year.
We consulted the priest and decided on the date for the memorial service.
