I don't know who decided to put so many Torii gates in a row, but it was a great idea. One of the most recognisable and photogenic tourist attractions in the world, this site is just pleasant to look at and walk through. Beware of the tourist hordes that always get in your pictures and are here any time of the year. If you want to avoid them come much earlier with the first rays of sun. Alternatively go slightly higher up the hill where there are less people as most of them seem to lack the stamina to finish the hike up the hill. Fun fact: the torii gates are payed for by businesses or influential rich people for good luck and fortune. The one who pays decides the writing on the gates, so I saw one which said Guest House in English. Anyways. great spot and I'm sure you were planning to go anyways.
