Literal
First-visit, divine-blessing [subject-が] exist [nominalizer-の] [topic-は] where [genitive-の] shrine?
A New Year's shrine-visit question. 初詣 (はつもうで) is the first shrine or temple visit of the new year, a major cultural tradition in Japan — people go in the first few days of January to pray for the year ahead. ご利益 (ごりやく) is 'divine blessing,' 'spiritual benefit,' 'the boon from praying to a deity.' Shrines and temples are often known for specific 'specialties' of ご利益 — some for love, some for academic success, some for health. The question is asking 'which shrine is most known for producing results?' ~のはどこ ('where is the one [such that] X') is a cleft question.
