Father's day

The last Sunday was the father's day in Japan.
Is it international holiday? I am not sure about it. Anyway, I think I need to do something for my father.
My father is not lucky person concerning family especially in his childhood so I think it is my responsibility to make sure
that he does not feel lonely or sad.
So I decided to invite my parents to my apartment and cook for them. They actually changed the plan saying they find my place is
too small and can not stay more than one hour and prefer to go somewhere together and eat something nice.
I agreed with them.
