Take warm clothes if you are visiting outside of summer.... its much colder here than the other parts of japan that we visited.
But loved it! i have seen some complaints about the morning prayers only being 'performed' by two monks... well i thought it was wonderful to witness. They aren't there to 'perform' its a beautiful prayer and just as great that they allow tourists to take a peek. What voices!
Really really recommend a late night walk through the cedar forest.... a little unnerving but completely worth it.
