We visited Suwa Shrine 諏訪神社 in October. This is a sprawling Shinto shrine located a top a very long set of stairs.
During our visit, they were setting up for a festival so there were plenty of workers climbing up and down the stairs. It was super hot on this day which made the climb up the stairs a bit tiring.
One you get up the main steps, there's plenty of things to look at and you can also walk to other nearby shrines in the area.
