New year's visit to a shrine

In my corporation, we go to New year's visit to a shrine in every year. But, I can't attend. It's a rule for religion that it's impossible to go to shrine in a year after family's death.
I don't take into such a religion. And, I like to see a building of shrine and the garden. But, my father said me not to go to shrine for a while. So, I decided not to go there.
Old people's religion always plug my way of life.
